That layer is what we build. The ECS Developer Platforms team owns the customer-facing API, AWS CloudFormation resource coverage, AWS Cloud Development Kit (CDK) constructs, and Terraform provider support for ECS. We are looking for a Software Development Engineer II who wants to design, build, and operate the API and Infrastructure-as-Code (IaC) surfaces that hundreds of thousands of AWS customers depend on. You will work in Java, TypeScript, and Go across three IaC ecosystems, collaborate with backend teams on every feature launch, and build internal platform tooling that the broader ECS organization relies on to ship safely. This is a newly formed team where you will have direct influence on technical foundations and architectural decisions that shape how ECS customers interact with the service for years to come., * Design and build customer-facing API endpoints and IaC resource providers (CloudFormation, CDK, Terraform) so that every new ECS capability ships with full developer surface coverage on launch day. * Collaborate with ECS backend pillar teams (Scheduling, Networking, Deployments) and AWS-wide IaC teams to co-design API contracts, resource models, and release plans for new features. * Own internal platform tooling - feature flag systems, automated testing pipelines, and deployment safety mechanisms - that the entire ECS engineering organization depends on to ship quickly and reliably. * Participate in code reviews, mentor fellow engineers, and author API and IaC design documents that define the developer experience for hundreds of thousands of AWS customers. * Investigate operational issues through oncall rotations and root cause analysis, driving permanent fixes that improve the reliability and performance of the API and IaC fleet. A day in the life You might start the morning reviewing operational metrics for the ECS API fleet, then join a design session with a backend team to model a new networking primitive as a CloudFormation resource and CDK construct. After lunch you could be writing Go code for the Terraform provider, reviewing a teammate's pull request for a feature flag rollout, or pairing with a newer engineer on contract testing for an IaC resource handler. You will regularly write design documents and coordinate release timelines with AWS-wide IaC teams. About the team The ECS Developer Platforms team sits within Amazon ECS under AWS Containers, alongside the Scheduling, Networking, and Deployments pillars. We are the only team in ECS with a horizontal view across every feature the organization ships - nothing is customer-visible until it passes through our layer. The team is small (8 to 10 engineers) and engineers own planning, prioritization, and cross-team coordination directly, which means more ownership and broader exposure than a typical software engineering role. We are investing in full IaC parity across all three ecosystems, greenfield internal platform capabilities, and the growing intersection of AI-generated infrastructure code, and we are looking for collaborative engineers ready to help shape what comes next. ## Related Videos - [Navigating the Corporate Jungle: Life as a Developer in a large Company](https://www.wearedevelopers.com/videos/621-navigating-the-corporate-jungle-life-as-a-developer-in-a-large-company) - [Celery on AWS ECS - the art of background tasks & continuous deployment](https://www.wearedevelopers.com/videos/561-celery-on-aws-ecs-the-art-of-background-tasks-continuous-deployment) - [Web APIs you might not know about](https://www.wearedevelopers.com/videos/281-web-apis-you-might-not-know-about) - [Go with the Flow: Stop the Leaks Before Your Memory's a Waterfall!](https://www.wearedevelopers.com/videos/100073-go-with-the-flow-stop-the-leaks-before-your-memory-s-a-waterfall) - [Super scaling for the Super Bowl: How to survive 30 million users hitting your backend in 30 minutes](https://www.wearedevelopers.com/videos/100356-super-scaling-for-the-super-bowl-how-to-survive-30-million-users-hitting-your-backend-in-30-minutes) - [How AWS Generates Polyglot Libraries Based on a Single TypeScript Codebase](https://www.wearedevelopers.com/videos/1026-how-aws-generates-polyglot-libraries-based-on-a-single-typescript-codebase) ## Related Articles - [Where to Find Entry-Level Software Engineering Jobs](https://www.wearedevelopers.com/magazine/397-where-to-find-entry-level-software-engineering-jobs) - [Best Countries for Software Engineers](https://www.wearedevelopers.com/magazine/267-best-countries-for-software-engineers) - [Is Software Engineering Hard?](https://www.wearedevelopers.com/magazine/448-is-software-engineering-hard) - [The 12 Best Jobs for Software Engineers](https://www.wearedevelopers.com/magazine/401-the-12-best-jobs-for-software-engineers) - [The Ultimate Software Engineer Career Path Guide for 2023](https://www.wearedevelopers.com/magazine/146-the-ultimate-software-engineer-career-path-guide-for-2023) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated)
