Senior Backend Engineer

Unico Connect · Mumbai, India, India

About the company

Unico Connect is seeking a Senior Backend Engineer to architect and deliver production backends for enterprise client products. The role spans system design, data-layer ownership, performance engineering, and the mentorship that scales the backend practice. The position is well suited to senior engineers with multi-database production experience, strong distributed systems instincts, and a track record of mentoring junior engineers through complex change.

What you will do

Lead backend architecture for 1-2 enterprise client products

Design event-driven and microservice systems where the trade-offs pay off; keep simpler architectures where they do not

Own the data layer: schema design, query optimisation, indexing strategy, and caching architecture

Implement complex business logic, workflows, and integrations spanning multiple services

Mentor 2-3 junior backend engineers through code reviews, design reviews, and 1:1s

Drive backend standards covering testing, observability, security, and performance

Partner with DevOps on deployment, scaling, and on-call practices

Lead production incident response for backend systems including post-mortems and remediation

Govern security posture across owned services including OWASP, SAST, and DAST practices

Author internal backend playbooks and onboarding documentation

Calibrate the backend interview bar and conduct senior interview loops

Requirements

5+ years of backend engineering with at least 2 in a senior or lead role

Deep expertise in Node.js with TypeScript or Python (FastAPI or Django) at production scale

Production experience across multiple databases (PostgreSQL, MySQL, MongoDB)

Strong fundamentals in distributed systems, caching, queues, and async patterns

Hands-on with Kubernetes, Docker, and CI/CD on GCP or AWS

Excellent code review and mentorship skills

Experience leading architecture decisions in regulated industries (SOC 2, HIPAA, GDPR)

Track record of owning at least 1 system at production scale (high QPS, multi-tenant, or compliance-heavy)

Capacity to read product requirements and translate to technical scope

Bachelor's degree in Computer Science, Engineering, or a related field

Nice to have

GraphQL federation experience (Apollo, Hive)

Performance engineering including profiling and query optimisation

Security hardening track record

Open-source contributions to backend libraries or frameworks

Comfortable with startup pace

Fast cycles, real ownership, low ceremony. You will not be a cog.

Driven by value creation

Output and outcomes matter more than process. You ship work that moves a metric.

You treat the codebase, the deliverable, and the client relationship as your own.
