Backend Engineer - Python/Django

About the Role :

We're looking for a Backend Engineer to own and scale the services that power NymbleUp's workforce-planning and scheduling platform across enterprise clients. You'll work on a Python/Django codebase backed by PostgreSQL and Celery, solving real production problems for large, multi-tenant deployments. This is a hands-on role for someone who genuinely enjoys digging into hard problems, reasoning through edge cases, and shipping reliable systems.

What You'll Do :

- Design, build, and maintain backend APIs and services using Python, Django, and Django REST Framework.

- Model data and write efficient queries against PostgreSQL - FK joins, indexing, and query optimization.

- Build and operate asynchronous workflows with Celery (scheduled jobs, background tasks, queues).

- Debug and resolve production issues across multi-tenant environments - trace root causes, not just symptoms.

- Write clean, well-tested, maintainable code and take part in code reviews.

- Collaborate with frontend, product, and DevOps to deliver features end-to-end.

- Contribute to performance, reliability, and security improvements.

Must-Have Qualifications :

- B.E./B.Tech in Computer Science (or equivalent CS engineering degree) - required.

- 3-5 years of professional backend development experience.

- Strong proficiency in Python and a modern web framework (Django/DRF preferred).

- Solid experience with relational databases (PostgreSQL) and writing performant SQL.

- Strong debugging skills - able to systematically isolate, reproduce, and fix complex production issues.

- Strong analytical and critical thinking - breaks down ambiguous problems and weighs trade-offs.

- Strong logical reasoning - designs correct, edge-case-aware solutions and can defend design decisions.

- Solid grasp of CS fundamentals : data structures, algorithms, complexity, and concurrency.

Good to Have :

- Experience with Celery or other task-queue / async processing systems.

- Familiarity with multi-tenant SaaS architectures.

- REST API design, authentication/authorization, and caching.

- Exposure to cloud infrastructure (GCP/AWS), Docker, and CI/CD.

- Comfort with Git-based workflows and a code-review culture.

What We're Looking For (Mindset) :

- A problem-solver who treats a tricky bug as a puzzle, not a chore.

- Someone who asks why before how, and reasons from first principles.

- Strong ownership - sees issues through from diagnosis to verified fix.

- A clear communicator who can explain technical decisions to peers.
