Overview

As a Senior Software Engineer you'll own significant parts of our Python backend — from architecture and API design to performance and reliability in production. You'll work on high-traffic Django and FastAPI services, mentor junior engineers and help set the engineering standards the team follows. We're looking for someone with 3-5 years of experience who has shipped and operated real systems, and who cares about maintainability as much as delivery speed.

Responsibilities

  • Own the design and delivery of backend features and services end to end
  • Architect scalable APIs and data models with Django and FastAPI
  • Improve performance: query optimisation, caching and async processing
  • Lead code reviews and raise the bar on testing and code quality
  • Mentor junior engineers and help them grow
  • Work with product managers to break down requirements into technical plans
  • Participate in on-call rotation and drive root-cause analysis for incidents

Requirements

  • 3-5 years of backend development experience, primarily in Python
  • Deep hands-on experience with Django and/or FastAPI in production
  • Strong SQL skills and experience tuning PostgreSQL or MySQL
  • Experience with caching (Redis) and message queues (Celery / RabbitMQ)
  • Good understanding of system design, API versioning and security best practices
  • Experience writing automated tests and working with CI/CD pipelines
  • Clear communicator who can explain trade-offs to technical and non-technical people

Skills

  • Python
  • Django
  • FastAPI
  • PostgreSQL
  • Redis
  • Celery
  • System Design
  • Docker

Nice to Have

  • Experience with microservices or event-driven architecture
  • Kubernetes, GKE or EKS
  • Observability tools (Prometheus, Grafana, Sentry)
  • Prior experience in HR-tech, payroll or fintech domains

Benefits

  • Competitive salary (₹12-16 LPA)
  • Health insurance for you and your family
  • Ownership of core product areas
  • Learning budget and conference support
  • Flexible working hours
  • Clear growth path towards Tech Lead
