We are looking for an enthusiastic and Senior Software Engineer to design, build, and operate secure, scalable, and high‑performing cloud‑native services.

You will be #LI-hybrid based in Hyderabad and reporting to Director Engineering.

You will work across our modern Python and TypeScript stack, contributing to mission‑critical systems that power our customer‑facing applications and backend platforms.

Our engineering environment spans modern web technologies, distributed systems, serverless services, microservices deployed on AWS ECS and Lambda, and robust event‑driven architectures. We embrace strong engineering fundamentals—clean architecture, high‑quality testing, observability, automation, and well‑documented APIs.

In this role, you will own technical solutions end‑to‑end: from discovery and design through implementation, testing, deployment, and production operations. You will collaborate closely with cross‑functional teams while mentoring engineers, raising engineering standards, and contributing to our long‑term technical strategy.

• Build backend services and APIs using Python, FastAPI, and Pydantic, ensuring clean interfaces and robust data contracts.
• Develop modern frontend applications with TypeScript and React, including shared UI patterns and components.
• Implement lightweight Node.js services using Koa for targeted functionality and middleware scenarios.
• Author and maintain high‑quality OpenAPI specifications and contribute to API documentation via Readme.io.

• Model and optimize relational schemas on Aurora PostgreSQL (RDS) and tune queries for performance.
• Use DynamoDB for high‑throughput use cases requiring fast, low‑latency access.
• Integrate S3 for object storage and collaborate on data pipelines using Glue and DMS where applicable.

• Design resilient asynchronous systems using SNS/SQS, ensuring idempotent processing, retry strategies, and operational safety.

• Deploy and operate services on AWS ECS and AWS Lambda behind API Gateway or ALB, using Terraform for IaC and Docker for containerization.
• Build observable systems leveraging CloudWatch for logs, metrics, and alarms.
• Participate in on‑call rotations and incident response, ensuring quick resolution and strong root‑cause discipline.
• Follow strong security practices using CloudTrail, GuardDuty, and SecurityHub.

• Drive automated testing across pytest, vitest, and TestCafe for backend, UI, and end‑to‑end coverage.
• Maintain healthy CI pipelines using GitHub Actions and Buildkite, ensuring dependency hygiene with Dependabot.

• Work closely with Product and Design on technical discovery, iterative delivery, and prioritisation.
• Conduct design reviews, contribute to architectural decisions, and provide constructive feedback through code reviews.
• Mentor engineers through pairing, knowledge‑sharing, and coaching on best practices.
• Maintain documentation and engineering context in Confluence and JIRA.

• 4 years of experience delivering production‑grade software systems.
• Strong proficiency in Python (FastAPI, Pydantic) and/or TypeScript (React, Koa).
• Hands‑on experience with AWS cloud services, including ECS, Lambda, API Gateway, ALB, and Terraform.
• Solid understanding of relational and NoSQL databases, particularly Aurora PostgreSQL and DynamoDB.
• Experience building event‑driven systems using SNS/SQS.
• Strong testing discipline using pytest, vitest, and TestCafe.
• Comfortable working in CI/CD environments with GitHub Actions and Buildkite.
• Knowledge of cloud observability and security tooling including CloudWatch, CloudTrail, GuardDuty, and SecurityHub.
