Senior Backend Engineer

About Barsys

Barsys builds connected smart hardware and a first-party advertising network for the U.S. spirits and beverage industry. We're a high-growth technology company with teams across New York, New Delhi, and London, and we're looking for a Senior Backend Engineer to help scale the systems behind our platform.

Location: New Delhi, India (in-person required)

About the Role

We're looking for a Senior Backend Engineer to own critical backend systems end-to-end — from design through production. You'll work across a modern polyglot stack (Go, Python, Node.js) while helping us evolve legacy PHP services, and you'll build on GCP at a company where engineering velocity is a competitive advantage. This is a high-ownership role for someone who wants to shape technical direction, not just execute tickets.

Responsibilities

Design, build, and maintain scalable backend services and APIs

Develop primarily in Go, Python, and Node.js, while supporting and evolving existing PHP services where needed

Design and optimize data models, queries, and persistence layers using PostgreSQL and MySQL

Build and operate cloud-native systems on Google Cloud Platform (GCP)

Own backend features end-to-end — from technical design through deployment, monitoring, and production support

Improve system reliability, performance, observability, and maintainability

Collaborate closely with product, frontend, mobile, and other teams on architecture and delivery

Contribute to technical direction, code reviews, engineering standards, and mentorship of other engineers

Use AI-assisted and agentic coding tools/workflows to accelerate development, testing, debugging, and documentation while maintaining strong engineering judgment and code quality

Core Experience

6+ years of professional backend engineering experience, at a Senior Engineer level or equivalent

Strong proficiency with Go, Python, and Node.js, with hands-on experience across all three

Experience maintaining or developing production applications in PHP

Strong SQL and relational database experience with PostgreSQL and MySQL

Production experience with GCP and cloud-based application architecture

Experience designing and operating REST APIs, distributed services, and asynchronous/background processing

Strong understanding of software architecture, testing, CI/CD, observability, security, and production operations

Comfortable diagnosing complex production issues across applications, databases, and infrastructure

Experience using AI coding assistants, coding agents, or agentic software-development workflows in real engineering work

Ability to work independently, make sound technical trade-offs, and take ownership of complex backend systems

Experience with containers, Docker, and modern observability tools

Based in or willing to relocate to New Delhi; this is an in-office role, not remote or hybrid

Nice to Have

Experience with event-driven architectures, queues, or messaging systems

Experience modernizing legacy systems or incrementally migrating services between technologies

Experience in fast-moving product or startup environments

Why Barsys

Join a fast-scaling team building category-defining hardware and ad-tech infrastructure for a multi-billion-dollar industry, with real ownership over systems used at scale from day one.
