Ratan

Tata and Tiger Global, and on a mission to make wealth creation accessible to every Indian. From first-time investors to seasoned traders, millions trust us to power their financial journeys. We're not just moving fast — we’re moving with purpose. If you thrive in a high-energy, high-impact environment, you're in the right place.

What you'd own

- Build and maintain our in-house developer platforms — full-stack applications that provision and manage resources across multiple environments, spanning Kubernetes, CI/CD and observability.
- Run a multi-cluster Kubernetes fleet across multiple regions — several hundred production services, with complete GitOps delivery.
- Develop and implement automation for infrastructure provisioning and related tooling to streamline engineering and infrastructure operations.
- Design, implement and maintain infrastructure components.
- Identify, diagnose and resolve performance bottlenecks and issues across environments.
- Advocate for and promote best practices in software development and enhance the developer experience across engineering teams.
- Own scaling, capacity and application performance strategy — defining SLOs and SLIs, managing error budgets, and driving capacity planning across the fleet.
- Manage security and compliance policies as code across the fleet.





Required

- Bachelor's degree in computer science or a related field, or equivalent work experience.
- Proficiency in at least one modern programming language — Python preferred, for building full-scale application services covering web frameworks, databases and queues (not just scripting).
- In-depth experience with AWS, Linux and Kubernetes.
- Proven troubleshooting skills with the ability to diagnose and resolve complex issues.
- Experience with CI/CD and automation pipelines, and familiarity with infrastructure-as-code (Ansible, Terraform) and GitOps (ArgoCD) tooling.
- Sound reasoning about concurrency and failure: idempotency, optimistic concurrency, delivery semantics.

Nice to have

- Understanding of extending the Kubernetes API: CRDs and controller runtimes.
- Service mesh experience, ideally Istio.
- Familiarity with LLMs and MCP, fluency with AI coding tools, and experience authoring skills for coding agents.
- A robust point of view on where AI should and shouldn't be trusted in a safety-critical system
