Software Developer

Team: Engineering

Location: Noida, Uttar Pradesh

Commitment: Full-Time

Workplace Type: onsite

Responsibilities

• API Layer: Build and maintain REST API endpoints using FastAPI — recruiter pipeline actions, candidate management, job configuration, and third-party integration webhooks.
• Data Modelling: Design and implement PostgreSQL data models — schema design, indexing, query optimisation via EXPLAIN ANALYZE, and Alembic migration management for new features.
• Multi-Tenancy: Build and maintain multi-tenant data access patterns — every query correctly scoped by tenant_id, no cross-tenant data leakage, new features inherit the isolation model from day one.
• Async Workers: Implement async worker tasks using AWS SQS and Celery — task design, retry logic, idempotency, and dead-letter queue handling for pipeline automation flows.
• Integrations: Build and extend third-party integrations — Lever ATS webhooks, SendGrid outbound and inbound parse, IMAP polling for the job-watch inbox, and AWS S3 for document storage.
• Testing: Write comprehensive test coverage — unit tests, integration tests, and async/webhook handler tests as a standard part of your workflow.
• Code Reviews: Participate in architecture discussions, code reviews, and technical documentation — raising quality concerns clearly and constructively.
• On-call: Contribute to on-call rotation — diagnose and resolve production incidents, write runbooks, and conduct post-mortems.
