Location: Bengaluru

Level: SDE III, individual contributor

Experience: 6+ years

Stack: Java, Spring Boot, Node.js, React, Kafka, Kubernetes, AWS

About the Role

We're hiring a small number of senior engineers who can take a business problem and deliver a shipped, running system. You'll own a domain end to end (claims, wallet, subscriptions, provider network, or payments), including its design, release, failures, cost, and long-term maintainability. Java and Spring Boot are the core, but you'll also write Node services, ship React screens, and run your own Kubernetes deployments and Kafka consumers.

What You'll Do
Own the high-level and low-level design of your domain, and get both reviewed before building
Build and maintain Java services and reliable APIs that other teams depend on
Get money and health data right: correct, traceable, and secure to retry
Run your services in production, with dashboards, alerts, and on-call ownership
Debug hard, intermittent issues and fix root causes
Set technical direction, review code, and mentor other engineers
Use AI tools (Copilot, Claude, ChatGPT) daily, while reading and owning every line you ship





What We're Looking For

Must have
6+ years of professional development, mostly in Java (8+, ideally 17+) and Spring Boot
Production Node.js and working React
System design experience, both HLD and LLD
Kafka or similar event-driven systems in production
Kubernetes and containers
SQL (MySQL/PostgreSQL) and MongoDB, including query tuning
Observability set up by you (Prometheus, Grafana, Sentry, ELK)
Extensive daily AI use in your workflow
Prior experience as owner and on-call for a system you built

Nice to have
Led a multi-team project or measurably improved a system's reliability, latency, or cost
Run an incident end to end and written the postmortem
Mentoring experience
TypeScript, React Native, or LLM API experience
Payments/fintech or health insurance domain exposure
Experience with regulated or sensitive data

How We Work High ownership, self-driven, quick with tests, and direct and low-ego. We'll assess coding, HLD, LLD, debugging, an ownership deep-dive, and collaboration.
