Back End Developer - Bengaluru (Whitefield)

farheen.akhtar@talentcorner.in

Job Title - Senior Back-End Developer

Location - Bangalore (Whitefield)

Experience - 3 to 5 years

Allocated Budget: 10 – 12 LPA (Non Negotiable)

For This is a senior back-end role — we expect depth in Python and in relational databases, and the ability to run what you build.

About the Role:

who writes production-grade server-side code. You will design and build the services and data layer behind our applications using Python, with relational databases underneath — all deployed and operated on AWS

What You'll Do:

• Design, build, and maintain Python (Flask/FastAPI) services and REST APIs consumed by our front ends and partners.

• Write and optimise advanced SQL — multi-table joins, subqueries, CTEs, and window functions — without leaning on an ORM to do the thinking for you.

• Model and evolve relational schemas, design indexes, and tune slow queries using EXPLAIN / EXPLAIN ANALYZE.

• Plan and run schema migrations safely against live data.

• Handle authentication, authorisation, and the security of the endpoints you expose.

• Build background jobs, queues, and scheduled work, and make them safe to retry.

• Write meaningful unit and integration tests for the code and modules you ship.

• Deploy, monitor, and troubleshoot services on AWS, and improve build and release pipelines.

• Review peers' code, uphold quality standards, and mentor less experienced developers. What

We're Looking:

• 5+ years of relevant, hands-on back-end development experience.

• Python — solid backend experience building REST APIs (Flask or FastAPI), not just scripting.

• SQL — ability to write advanced queries from scratch and reason about how they execute; PostgreSQL and/or MySQL in production.

• Schema design, indexing, and query optimisation on real data volumes.

• AWS — practical experience deploying and running workloads (e.g. ECS/Fargate, Lambda, RDS).

• API security — authentication and authorisation (JWT, OAuth2) and common OWASP risks.

• Testing — able to write proper unit and integration tests with pytest.

• Comfort with Git workflows, Docker, and CI/CD pipelines.

This Role Is Not a Fit If…

• You work only in Java and have no Python experience or familiarity.

• You rely entirely on ORMs and cannot write raw SQL queries yourself.

• Your Python is scripting and automation only — you have never built and run a production service. • You have never worked with AWS. (Experience on GCP or Azure is a plus, but AWS experience is required.)

• You have never written tests for your own code.

• You are looking for a role that is mostly front-end work.

Nice to Have

• Async Python (asyncio) and an understanding of concurrency trade-offs.

• Queues and background processing — Celery, SQS, or Kafka.

• Caching strategies with Redis, and knowing when not to cache.

• Infrastructure as code (Terraform or AWS CDK).

• Observability — structured logging, metrics, tracing, and useful alerts.

• NoSQL stores (MongoDB, DynamoDB) alongside relational databases.

• Enough front-end familiarity (Angular or React) to debug an integration end to end.
