Python Full-Stack Developer (Flask + Postgres)

Python Full-Stack Developer (Flask + Postgres)

About the Role

We are looking for a strong Python Full-Stack Developer with hands-on experience in Flask + PostgreSQL, especially for data-heavy systems. The candidate must be able to handle backend architecture, optimized SQL queries, and basic geospatial operations using PostGIS. Basic React skills are a plus.

Core Backend Requirements (Non-Negotiable)Python + Flask

• Strong hands-on experience building API-driven backends using Flask (Blueprints, middleware, error handling, request lifecycle).
• Ability to design modular, maintainable backend architectures.
• Experience with data-heavy endpoints, pagination, and efficient serialization.

PostgreSQL

• Solid understanding of relational schema design, indexes, constraints.
• Ability to write high-performance SQL queries (not ORM-only developers).
• Familiarity with query optimization, EXPLAIN plans, avoiding N+1 queries.

PostGIS (Basic but Practical Experience Required)

You don’t want an academic PostGIS user — you want someone who has actually used it.

Candidate should know:

• Basic understanding of geometry/geography types.
• Ability to write geospatial queries:
• Distance
• Bounding boxes
• Intersects / Contains
• Proximity searches
• Awareness of spatial indexing and performance considerations.

Frontend (Good to Have)

(Not mandatory, but preferred)

• Basic to intermediate React experience.
• Ability to build/maintain simple dashboards, forms, and map-based UIs.
• Understanding of component-driven UI and API integration.
• Should be capable of handling front-end tasks independently (not expected to be a React expert at 2–3 years).

Scale & Data-Intensive System Experience

A qualified candidate should have:

• Worked on platforms involving large datasets, heavy SQL queries, or complex ETL pipelines.
• Experience with background jobs (Celery or any queue-based system).
• Understanding of caching layers (Redis), rate-limiting, and performance bottlenecks.
• Experience deploying and maintaining production systems, not just internal tools.

Engineering Maturity Requirements

• Writes clean, readable, well-documented code.
• Able to reason about trade-offs — not blindly follow tutorials.
• Communicates issues early and proposes solutions.
• Understands the difference between a quick prototype and a production-ready system.

Expected Outcomes

• Own backend modules confidently.
• Handle 80% of Flask + SQL workloads independently.
• Support geospatial features without needing constant help.
• Build reliable frontend screens when required.
• Contribute to scaling and architectural decisions instead of creating bottlenecks.
