Job summary

EPAM Systems seeks a Senior AWS Cloud Native Developer to build a paved-road platform enabling AI-native engineering with agents as first-class developers. You will craft patterns, develop Python/FastAPI APIs, and implement cloud-native tooling on AWS, with Terraform-based infrastructure and automated governance.

You will drive delivery pipelines, security-by-default practices, and observability while collaborating across fast-moving teams from early stages.

Qualifications

• 5+ years of application development with the ability to define patterns for other engineers.
• Proficiency in Python and FastAPI for building production APIs and services.
• Strong AWS application development experience, ideally with developer tooling or cloud-native workflows.
• Terraform for infrastructure-as-code usage.
• Daily experience with AI coding harnesses/agents and spec-driven development.

Responsibilities

• Define and encode application-development patterns and quick starts for other teams.
• Build production APIs and services using Python and FastAPI.
• Develop cloud-native applications on AWS including tooling and delivery platforms.
• Design and maintain infrastructure as code with Terraform.

Job description

We are looking for a Senior AWS Cloud Native Developer to help build a paved-road platform from the ground up — one that lets every engineering team build in an AI-native way, with agents as first-class developers, automation and governance built in, and a fast, safe path from idea to production. This is a hands-on, close-to-the-code build role where the systems and patterns you create will serve as the foundation every engineering team works on top of.

Responsibilities

• Define and encode application-development patterns and quick starts that other engineering teams can rely on.
• Build production APIs and services using Python and FastAPI.
• Develop cloud-native applications and tooling on AWS, including developer tooling and delivery platforms.
• Design and maintain infrastructure as code using Terraform.
• Drive engineering work with AI coding harnesses/agents, following spec-driven development practices.
• Integrate AWS serverless and event-driven services such as 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 automated governance, compliance, and operational controls within delivery pipelines.
• Implement deterministic scripted checks and agentic applications for problems that require reasoning and judgment.
• Apply strong engineering practices, including API design, automated testing, observability, documentation, and secure-by-default delivery.
• Operate independently within a fast-moving program and contribute from early stages.

Requirements

• 5+ years of application-development experience with the ability to define patterns and quick starts 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.
• Daily experience using AI coding harnesses/agents, with familiarity with 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, IaC, and automated evidence capture.
• Background in building automated governance, compliance, or operational controls into delivery pipelines, using both deterministic scripted checks and agentic applications.
• Understanding of good engineering practice, 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/React for web front ends and developer consoles.
• Experience building internal developer platforms or "platform-as-a-product".
• Experience building agentic applications, or designing APIs/CLIs and reusable skills for both human and agent consumers.
