What does an AWS ECS developer do?
An AWS ECS developer builds and operates containerized applications on Amazon Elastic Container Service by defining task configurations and managing service deployments. This role focuses on translating application requirements into running containers within a managed cluster environment. The developer handles the lifecycle of these containers from initial definition through active operation and updates.
- Authors JSON-based task definitions that specify container images, CPU and memory limits, and environment variables for each application component. These definitions act as blueprints that tell the ECS cluster how to launch and run specific containers. The developer registers new revisions of these definitions whenever application code or configuration requirements change.
- Configures ECS services to maintain a desired number of running tasks across the cluster infrastructure. This work involves setting deployment strategies such as rolling updates or blue/green deployments to minimize downtime during releases. The developer integrates these services with Application Load Balancers to route incoming traffic to healthy container instances automatically.
- Diagnoses failed deployments and unhealthy task states by reviewing service event histories and container logs. This troubleshooting process identifies issues related to resource constraints, networking permissions, or incorrect image references. The developer iterates on task definitions and service settings to resolve these operational failures and restore stable application performance.
How to hire an AWS ECS developer on Upwork
Step 1: Post a job
Describe your container orchestration needs in a few sentences and let Job Post Generator powered by Umaโข, Upwork's Mindful AI draft a precise job post for the role. You can write a new post, update a saved draft, or reuse an existing post to start finding candidates quickly.
- Specify requirements for creating Amazon ECS task definitions and configuring services to run within an ECS cluster.
- List necessary experience with AWS networking, IAM roles, and Application Load Balancer integration for secure container communication.
- Define expected deliverables such as updated service configurations and operational documentation for running ECS-based releases.
Step 2: Evaluate candidates
Look for portfolios that demonstrate hands-on management of deployment strategies like rolling or blue/green updates for ECS services. Uma can run instant video interviews and build shortlists with side-by-side comparisons to help you assess technical fit.
- Verify experience registering task definition revisions and deploying them to production clusters using the AWS CLI or console.
- Check for examples of troubleshooting failed deployments and diagnosing unhealthy tasks within the ECS service history.
- Confirm familiarity with CI/CD orchestration tools that launch ECS deployments and manage container image references.
Step 3: Interview your top choices
Discuss specific scenarios involving traffic shifting and service scaling to gauge their practical knowledge of Amazon Elastic Container Service. Schedule and conduct these interviews within Upwork Messages to receive an immediate transcript and summary after each one.
- Ask how they configure deployment controllers to shift traffic between environments during a blue/green release.
- Request details on how they monitor task behavior and adjust desired task counts for optimal performance.
- Explore their approach to updating container images and managing version control for task definitions.
Step 4: Agree on scope and begin work
Define clear milestones for building task definitions and configuring deployment strategies before starting the engagement. Use Upwork Messages and the contract workroom for communication and project management, plus identity verification, payment protection, hourly tracking, and project funds for security.
- Set deliverables for initial ECS task definition creation and subsequent service configuration updates.
- Establish a timeline for implementing deployment configurations and testing traffic shift components.
- Agree on documentation standards for operating and updating the ECS-based release process.
