- Optimize application performance, including query optimization and caching strategies.
- Design and optimize relational (PostgreSQL) data models
- Write efficient queries, manage migrations and ensure data integrity across services
- Build and maintain CI/CD pipelines for automated testing and deployment
- Work with containerization (Docker) and orchestration (Kubernetes) where applicable.
- Write and maintain unit, integration, and end-to-end tests (pytest, unittest or equivalent)
Cross-functional & delivery
- Communicate proactively with the client's technical and non-technical stakeholders on progress, risks, and design tradeoffs
- Participate in sprint/PI planning and translate high-level or ambiguous requirements into concrete technical designs and acceptance criteria
- Mentor junior developers on the team and review their code, particularly around AI-integration and validation logic
Required Qualifications & Skills
- 5-8+ years of professional software development experience, with strong depth in Python (3.x)
- Backend framework expertise -Django or FastAPI
- Database expertise - strong SQL skills, experience with at least one relational database ( PostGres)
- API design - REST Principles, authentication/authorization patterns (OAuth2, JWT)
- Cloud platform experience - hands-on with AWS, Azure, or GCP (compute, storage, managed databases)
- Version control & collaboration - Git, code review workflows or GitFlow branching strategies
- Testing discipline - strong track record of writing maintainable, meaningful test coverage
- CI/CD - experience building or maintaining pipelines
- Strong communication skills - able to explain technical tradeoffs to non-technical stakeholders and write clear documentation
- Problem-solving and debugging - comfortable diagnosing issues across the full stack, from frontend rendering to backend performance to infrastructure
Nice to Have
- AI/LLM familiarity - exposure to integrating LLM APIs into application workflows
- Prompt engineering - basic understanding of structuring prompts and structured/JSON output handling
