Senior Full Stack Developer

As a Senior Full Stack Developer, you will focus on implementing complex features and architectural improvements across our technology stack. Key Responsibilities and work requirements

• Implement complex features across frontend and backend components.
• Work with architects to implement microservices patterns according to best practices.
• Develop and optimize API gateway implementations.
• Participate in code reviews and technical discussions.
• Implement security best practices and improvements.
• Optimize application performance and scalability.
• Participate in architectural design discussions.
• Contribute to technical documentation.
• Share knowledge and best practices with the rest of the team.
• Participate in Agile ceremonies and technical planning.
• Collaborate with the DevOps team on deployment and infrastructure improvements.
• Collaborate with the Product team and other stakeholders.

• 5+ years of professional software development building and shipping production web applications.
• 3+ years working on at least two of the following in production:
• Modern frontend: React or Angular (TypeScript), including component architecture, routing, forms, and client-side state/data fetching.
• Backend APIs: ASP.NET Core (C#) or PHP (7.4+), including REST design, authentication/session handling, and integration with external services.
• Demonstrated delivery of end-to-end features (API + UI or API + integration), including debugging across service boundaries.
• Experience with HTTP-based integrations in distributed environments (third-party APIs, retries/timeouts, idempotency awareness, session or token propagation).
• Working knowledge of web security basics: input validation, authn/authz patterns, secrets via environment/config (not source control), and safe handling of user-provided data.
• Experience participating in code reviews, technical design discussions, and Agile planning (refinement, estimation, retros).

Strongly desired (meet most, not necessarily all)

• React + .NET experience on a BFF-style backend (orchestrating multiple backends, caching/session stores such as Redis).
• Angular experience on a large, long-lived SPA (including incremental modernization alongside older client code).
• PHP experience maintaining a mature server-side application (Composer, MVC-style layout, public APIs and webhooks).
• Familiarity with cloud-hosted deployments (containers, CI pipelines, environment-specific configuration); you will collaborate with DevOps on releases and infra changes rather than owning all of IaC.
• Exposure to AWS and/or Azure (APIs, identity, or hosted services).
• Automated testing discipline: unit tests (e.g. Vitest/xUnit) and comfort with E2E or integration testing practices on your team.
• Proficient English for written technical work; spoken English for day-to-day team syncs.

Preferred Qualifications

• Experience in HR tech, assessment, or similar B2B enterprise products (multi-tenant orgs, roles, billing, compliance-minded UX).
• Practical use of resilience patterns for outbound HTTP (retries, circuit breakers, structured logging).
• Monitoring and observability (structured logs, traces, or APM) in services you have operated.
• Contributions to shared libraries or internal SDKs consumed by multiple services.
• Familiarity with domain modeling (bounded contexts, clear service boundaries); explicit DDD certification not required.
• Open-source contributions or maintainership.
