Skills to Look for When Hiring Salesforce Developers

Hiring a Salesforce developer looks easy on paper. Post the job, get applications, check for certifications, run a technical round, make an offer. The problem is that this process filters for the wrong things. It finds people who know Salesforce on paper but misses whether they can solve your specific business problems inside the platform.

The result is a hire who passes the interview, struggles in production, and leaves within a year. Or worse, stays and builds a codebase that nobody else can maintain.

The skills that actually determine whether a Salesforce developer will work well in your environment are not always the ones that show up first on a resume. This guide breaks down what to look for, what to test, and what to verify before making the call.

Technical Skills That Are Non-Negotiable

Apex Programming

Apex is Salesforce’s proprietary backend language. Any developer doing serious work on the platform writes it regularly. But knowing Apex syntax is not the same as knowing how to write good Apex.

The distinction that separates average Apex developers from strong ones is how they handle governor limits. Salesforce enforces hard caps on resource usage within a single transaction — maximum number of SOQL queries, maximum records processed in a loop, maximum CPU time. Developers who write without accounting for these limits produce code that works in a sandbox with 50 records and throws exceptions in production with 50,000.

When evaluating Apex skill, ask candidates to walk through how they would handle bulk data processing. Ask them to explain what a governor limit violation looks like and how they have avoided or fixed one. A developer who cannot answer this specifically has not built at scale.

Also look for clean code habits: meaningful variable names, modular methods, comments that explain why rather than what, and consistent formatting. Code that only the original author can read is a maintenance liability.

SOQL and the Salesforce Data Model

Salesforce Object Query Language is how developers retrieve data from Salesforce’s database. It looks similar to SQL but has platform-specific behavior that matters.

More important than SOQL syntax is whether the candidate understands the Salesforce data model: how standard objects like Account, Contact, Opportunity, and Case relate to each other, how custom objects and fields integrate into that model, and how lookup relationships and master-detail relationships affect data retrieval and deletion behavior.

A developer who does not understand the data model will write queries that pull too much data, miss relationship traversal, or ignore field-level security in ways that create access control problems.

Lightning Web Components

Modern Salesforce front-end development uses Lightning Web Components, which is a JavaScript and HTML-based framework running on the Lightning platform. If your team needs any custom user interface — a tailored record page, a custom form, an embedded dashboard — the developer needs to know LWC.

Ask candidates to describe a Lightning component they have built. What did it display? How did it communicate with Apex? What event handling was involved? A developer with real LWC experience will answer with specific architectural decisions. Someone who has only read documentation will give a theoretical answer.

REST and SOAP API Integration

Salesforce rarely runs in isolation. It needs to share data with ERP systems, marketing platforms, billing tools, customer support software, and internal databases. Integration is built through APIs, and a developer handling this work needs to understand both REST and SOAP protocols, OAuth authentication flows, error handling for failed callouts, and how to manage asynchronous integration when real-time connections are not practical.

Ask candidates about specific integrations they have built. What was on the other side? How did they handle authentication? What happened when the external system was unavailable? Strong integration developers have stories about failure scenarios and how they handled them — retry logic, dead letter queues, alerting when something stops syncing. Developers without integration experience will not have these stories.

Salesforce Flow and Automation Tools

Not everything in Salesforce requires Apex. Flow is a powerful automation tool that can handle record updates, multi-step processes, screen flows for guided user interactions, and scheduled automation without code. A skilled developer knows when Flow is the right tool and when Apex is necessary.

The distinction matters because Flow is easier to maintain than Apex for non-developers. If a business analyst can adjust a Flow without opening a code editor, that is a meaningful operational advantage. Developers who default to Apex for everything they build are creating maintenance overhead that did not need to exist.

Test this by describing a business requirement and asking how the candidate would approach it. The right answer depends on the scenario, but a developer who always reaches for Apex without considering Flow has a gap.

Platform Knowledge Beyond Code

Salesforce Security Model

The Salesforce security model is layered and complex: organization-wide defaults, roles and role hierarchy, profiles, permission sets, sharing rules, field-level security. A developer who does not understand this model will build features that expose records to the wrong users or block access where it should exist.

Ask candidates to explain how they would implement a requirement where specific users need access to records they do not own, without giving everyone that access. The explanation reveals whether they understand the full security stack or just surface-level profile settings.

Deployment and Version Control

Moving code from a sandbox to production is a formal process in Salesforce. Developers use Salesforce CLI, change sets, or tools like Copado or Gearset to manage deployments. They need to understand how to handle conflicts, how to sequence deployments that depend on each other, and how to roll back if something breaks in production.

Version control matters just as much. A developer who does not use Git or an equivalent source control system is working without a safety net. When something breaks, there is no clean way to identify when it changed or revert to a known good state.

Ask how they manage deployments. Ask what version control they use and how their branching strategy works. If the answer is “we use change sets and I don’t really use Git,” that is a flag for any team managing a complex org.

Salesforce Testing Standards

Salesforce requires 75 percent code coverage by unit tests before deployment. That requirement is easy to game — developers can write tests that cover lines of code without actually testing behavior. A developer who treats testing as a coverage metric rather than a quality check is producing unreliable code.

Good testing practice includes testing with realistic data volumes, testing negative cases and error handling, and using test factories to create consistent test data rather than hardcoding values. Ask to see test classes from previous work. How many assertions are there per test? Do the tests cover edge cases or just the happy path?

Certifications: What They Signal and What They Do Not

Salesforce certifications are a useful starting point but should not be the primary hiring filter.

Platform Developer I is the baseline. Passing it demonstrates foundational knowledge of Apex, the data model, testing, and deployment. It is a reasonable minimum expectation for anyone taking on development work.

Platform Developer II is harder and covers advanced design patterns, asynchronous programming, and performance optimization. It is less common and does indicate a stronger knowledge of the platform at depth.

JavaScript Developer I covers Lightning Web Component development. Relevant for developers with a front-end focus.

Salesforce Architect certifications — Application Architect, System Architect, Technical Architect — are relevant when hiring for senior roles that involve platform design decisions across a complex org.

Where certifications fall short is in predicting whether someone can work well under ambiguous requirements, debug a production issue under pressure, or communicate clearly with non-technical stakeholders. These things do not appear on a certification exam and they show up on the job every week.

Treat certification as a filter that rules out people who have not engaged seriously with the platform, not as a guarantee of quality.

Soft Skills That Affect Real Output

Translating Business Requirements into Technical Solutions

A Salesforce developer works with sales managers, operations teams, and executives who cannot describe their needs in technical terms. The developer who can sit in that conversation, ask the right questions to uncover the actual requirement, and then explain the technical approach in plain language is worth considerably more than someone who needs a perfect specification handed to them before they can start.

Test this directly. Give a candidate a vague business scenario — “our sales team wants to see a summary of customer activity before they make a call” — and ask how they would approach building it. Watch whether they ask clarifying questions or jump to a solution. The questions they ask reveal how they think about requirements.

Debugging Under Pressure

Production issues in Salesforce — triggers firing unexpectedly, integration callouts failing silently, workflows creating duplicate records — require a developer who can diagnose under pressure, communicate what they are finding while they work, and make changes carefully rather than frantically.

Ask candidates to describe a production incident they have resolved. What were the symptoms? How did they diagnose the cause? What did they do to fix it and prevent recurrence? A developer with production experience will walk you through this with specific detail. A developer who has only worked in sandboxes will not have a real answer.

Written Communication

Salesforce developers document their work — technical specifications, release notes, runbooks for support teams. A developer who writes clearly reduces the knowledge transfer burden when they are unavailable or eventually leave.

Ask for a writing sample. Review their code comments. Check whether their previous documentation (if they can share it) is something a new team member could use to understand a feature without sitting down with the original developer.

How Advayan Sources Salesforce Developers

Finding a developer who covers all of these bases through a standard recruitment process is time-consuming and uncertain. Advayan provides Salesforce developers as part of a managed service arrangement, which means you get access to a team that has already been evaluated against these criteria rather than running that evaluation yourself.

The team covers the full range: Apex and LWC development, API integration, Flow and automation, data migration, and deployment management. If a project requires a specific combination of skills — an integration-heavy build that also needs significant front-end work — the team draws on multiple specialists rather than expecting one person to cover everything.

For organizations that want to augment an existing in-house team for a specific project, Advayan also provides staff augmentation with Salesforce developers who can work alongside your team on defined deliverables.

FAQ

1. What is the most important skill for a Salesforce developer?
   Apex programming with a solid understanding of governor limits is the most critical technical skill. Beyond that, the ability to translate ambiguous business requirements into working solutions is what separates developers who create real value from those who can only execute precise specifications.
2. Do Salesforce developers need to know JavaScript?
   Yes, for front-end work. Salesforce’s Lightning Web Components framework uses JavaScript and HTML. Developers focused on back-end logic and integration can get by with minimal JavaScript knowledge, but any developer doing UI work needs to be comfortable with it.
3. How do I test a Salesforce developer’s skills before hiring?
   Give them a take-home exercise that mirrors a real scenario from your environment — a bulk data processing requirement, a small integration, or a UI component. Review the code for governor limit handling, test coverage, naming conventions, and overall structure. Also ask them to debug a piece of intentionally broken code and explain what they found.
4. What is the difference between a Salesforce developer and a Salesforce architect?
   A developer writes code and builds solutions within the platform. An architect designs the overall structure of the Salesforce org — how data is modeled, how integrations are structured, how security is layered, and how the system scales. Architects typically have significant development experience and work at a higher level of abstraction. Most organizations need developers first and bring in architect-level thinking when complexity warrants it.
5. Should I hire a Salesforce developer full-time or use a managed service?
   Full-time hiring makes sense when Salesforce development needs are constant, complex, and require deep organizational knowledge built over time. A managed service is more practical when needs vary — a major project followed by maintenance, or specialized skills needed for a defined period. Managed services also remove the risk of a single developer being a knowledge bottleneck.
6. Can Advayan provide Salesforce developers for both short projects and long-term support?
   Yes. Advayan works with clients on project-based engagements with defined deliverables and on ongoing managed service arrangements covering development, support, and continuous improvement. The engagement model is scoped to what the client actually needs rather than a fixed format.
