Requirements:
7+ years of experience building production-grade backend systems, with deep expertise in TypeScript and Node.js – Must
Strong track record designing and evolving distributed, event-driven architectures (microservices, asynchronous systems, serverless where appropriate) – Must
Experience building cloud-native systems on AWS, with a strong understanding of tradeoffs in scalability, reliability, and cost – Must
Hands-on experience using Kafka in real production environments, with strong understanding of internals (partitioning, ordering, consumer groups, delivery semantics, scaling, failure modes) – Must
Practical experience with Docker-based workflows and modern containerized development practices – Must
Familiarity with Kubernetes (including EKS) and/or ECS, and understanding how services behave when deployed and scaled in container orchestration environments – Must
Strong experience working with both NoSQL (MongoDB) and relational databases (Postgres), with clear understanding of data modeling and tradeoffs – Must
B.Sc. in Computer Science or equivalent experience
(AI-driven engineering practices)
Experience using AI-assisted development tools (ChatGPT, Claude, GitHub Copilot, Cursor, etc.) as part of daily engineering workflows – Must
Experience leveraging LLMs to improve productivity in coding, design exploration, technical writing, and analysis – Must
Familiarity with LLM APIs (OpenAI, Anthropic, etc.) and having built small tools or integrations using them
Ability to critically assess AI-generated output and apply strong engineering judgment
Interest in emerging AI tooling and how it can enhance, not replace, strong software engineering practices.
