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 safe 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 regulat
