We're one of India’s fastest growing fintech platforms, backed by the best in the business, including Mr. 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.
• Experience- 3-5 Years
• 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 strong point of view on where AI should and shouldn't be trusted in a safety-critical system
