Responsibilities

• Build and maintain web applications using React (TypeScript preferred).

• Develop backend services/APIs using Python (FastAPI/Flask/Django).

• Design clean, maintainable, testable code; write solid unit/integration tests.

• Work effectively with AI coding tools:

  • Use AI for scaffolding, refactoring, test generation, and debugging.

  • Validate and correct AI output (security, edge cases, performance, correctness).

  • Document decisions and trade-offs clearly.

• Collaborate in PR-based workflows (GitLab) and participate in code reviews.

• Contribute to architecture discussions and pragmatic technical decisions.

Core Engineering Skills

• 3+ years of professional software development experience.

• Strong React experience (hooks, component patterns, state management, performance basics).

• Backend experience with Python building APIs (REST; GraphQL is a plus).

• Comfort with relational databases (PostgreSQL/MySQL) and/or NoSQL (MongoDB).

• Strong fundamentals: HTTP, async programming, data modeling, error handling, logging.

• Testing experience: Jest/Vitest/RTL/Cypress (frontend) and/or pytest (backend).

• Cloud experience (Azure/AWS/GCP), Docker/Kubernetes.

• Security basics (OWASP, auth patterns, secrets management).

AI-Assisted Development

You should be able to demonstrate:

• Confident daily use of Cursor, GitHub Copilot, or equivalent (your choice).

• Prompting and iterative refinement skills (driving the tool, not being driven by it).

• Ability to spot hallucinations/bugs, correct them quickly, and explain what happened.

• Good judgment on when not to use AI output verbatim (security, correctness, style).

• Using AI to accelerate:

  • Refactoring with confidence (incl. updating tests).

  • Writing or improving tests.

  • Tracing bugs and producing minimal reproducible fixes.

  • Creating clear docs and PR descriptions.
