Lead AWS Application Developer

We are looking for a hands-on Lead AWS Application Developer to help shape a greenfield internal developer platform from the ground up — one that enables AI-native engineering across the organization, with agents as first-class developers, built-in automation and governance, and a fast, safe path from idea to production. This is a build role close to the code, where the systems and patterns you create become the foundation every engineering team builds upon, making other engineers faster and bringing AI-native engineering within reach for the entire org. Responsibilities Define how applications should be built well and encode that knowledge as reusable patterns and quick starts for other engineering teams Build production APIs and services using Python and FastAPI Develop cloud-native applications and developer tooling on AWS, focusing on delivery platforms and developer workflows Design and maintain infrastructure as code using Terraform Drive engineering work using AI coding harnesses and agents, applying spec-driven development practices Integrate AWS serverless and event-driven services, including Lambda, API Gateway, and Step Functions Automate CI/CD, SDLC, and engineering controls using GitHub Actions, IaC, and automated evidence capture Turn policy and regulatory requirements into code and evidence by building automated governance, compliance, and operational controls into delivery pipelines Apply deterministic scripted checks and agentic applications where judgment-based reasoning is required Maintain strong engineering practices across API design, automated testing, observability, documentation, and secure-by-default delivery Operate independently in a fast-moving program and contribute value from early on Requirements 5+ years of application-development experience with enough real-world depth to define best practices and encode them as patterns for other engineers Proficiency in Python and FastAPI for building production APIs and services Strong AWS application development and software engineering experience, ideally with developer tooling, delivery platforms, or cloud-native developer workflows Skills in Terraform for infrastructure as code Familiarity with AI-assisted engineering practices, including daily use of coding harnesses/agents and spec-driven development Knowledge of AWS serverless and event-driven services such as Lambda, API Gateway, and Step Functions, and how to integrate them Experience automating CI/CD, SDLC, and engineering controls using GitHub Actions and IaC with automated evidence capture Background in building automated governance, compliance, or operational controls into delivery pipelines, turning policy and regulatory requirements into code and evidence Competency in both deterministic scripted checks and agentic applications that reason over judgment-based problems Understanding of good engineering practice as second nature, including API design, automated testing, observability, documentation, and secure-by-default delivery Capability to operate independently in a fast-moving program and contribute from early on English proficiency at B2 level or higher Nice to have Skills in TypeScript and React for web front ends and developer consoles Experience building internal developer platforms or platform-as-a-product Background in building agentic applications, or designing APIs/CLIs and reusable skills for both human and agent consumers
