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
