Backend Engineer

Roles And Responsibilities

• Design, build, and maintain high-performance backend services and APIs using Python + FastAPI
• Develop scalable systems that power Search, Data pipelines, integrating with ML models, and analytics workflows
• Write efficient queries and manage relational data using PostgreSQL
• Implement caching, async processing, and optimized API patterns for low latency
• Improve API reliability, scalability, and maintainability through best practices and clean architecture
• Debug production issues quickly and confidently (logs, tracing, profiling, root cause analysis)
• Collaborate closely with product + data teams to ship features end-to-end
• Build tooling and developer-friendly systems (internal APIs, admin panels, automation utilities)
• Work closely with Product on feature estimation, planning
• Write robust unit test cases

Required Skills & Experience

• 8+ Years of backend development in any of technologies (Python, Java, Go )
• Strong experience with Python backend development (asyncio, background jobs, queues) is preferred.
• Hands-on expertise with FastAPI (or similar frameworks like Flask/Django + willingness to adapt) is preferred.
• Solid experience with PostgreSQL and SQL optimization
• Experience integrating search systems like Algolia (or Elasticsearch/OpenSearch)
• Strong debugging skills: ability to diagnose tricky performance issues and production failures
• Experience building scalable API systems with performance in mind (rate limiting, pagination, async, caching, batching, etc.)
• Familiarity with system design fundamentals (scalability, concurrency, reliability)
• Comfortable working in a fast-moving startup environment
• Excellent communication skills

Nice-to-Have Skills

• Knowledge of Docker, CI/CD, cloud deployment (AWS/GCP/Azure)
• Familiarity with monitoring tools (Sentry, Prometheus, Grafana, Datadog)
• Experience in proptech, fintech, or data-heavy platforms
• Understanding of ranking/scoring systems, relevance tuning, or search optimization
• Exposure to LLM-powered tooling and workflows

We Love Engineers Who

• are obsessed with clean, readable, scalable code
• treat debugging like a superpower
• think in terms of latency + throughput
• enjoy using tools like Cursor / Copilot / AI-assisted dev workflows
