AWS DevOps Engineer (Freelancer)

Mactores is the agent-native AWS modernization firm. Most modernization work doesn't ship, it stalls in pilots, slips a year, or lands at three times the budget. We exist to ship it: production systems running, legacy retired, outcomes measured. Our delivery is built on Aedeon, the agent platform built by Mactores' founders' sister company, which absorbs the repetitive 60–70% of engagement work, discovery, dependency mapping, validation, test generation, that traditional consulting bills human hours against. Forward-deployed engineers own the rest: architecture, judgment, and cutover, on dates we commit to in the contract.

This freelance role sits in our infrastructure modernization work under the Application & Database Modernization pillar: moving legacy infrastructure and large enterprise workloads to AWS, and making the resulting platforms boring to operate. Customers come to us with hand-built environments, release cycles that depend on heroics, and big data workloads that outgrew their monitoring years ago.

You'll work as a hands-on DevOps engineer on customer deployments, Infrastructure as Code, CI/CD, automated monitoring — for enterprise applications, customer applications, and big data workloads. Aedeon absorbs the discovery and validation grind; your billed hours go to the automation and reliability engineering that gets releases out and keeps them out. It's client-facing work: you set customer expectations and then meet them.

What you will do?

• Automate infrastructure creation using Terraform and AWS CloudFormation.
• Run application configuration management and enable Infrastructure as Code through deployment tools.
• Own and manage the build and release cycle for customer projects.
• Share responsibility for deploying releases and other operations and maintenance activities.
• Improve operations infrastructure: Jenkins clusters, Bitbucket, monitoring tools (Consul), and metrics tools like Graphite and Grafana.
• Provide operational support for the engineering team and help migrate legacy infrastructure to the cloud.
• Establish and enforce operational best practices, including monitoring for automated system health checks.
• Build scalable infrastructure for data platforms-Amazon EMR, Redshift, and SageMaker.
• Build our CI pipeline, and train and guide the team in DevOps practices.

What are we looking for?

• 4+ years of experience using Terraform for IaaC.
• 4+ years of configuration management and engineering for large-scale customers, ideally supporting an Agile development process.
• 4+ years of Linux or Windows administration experience.
• 4+ years with version control systems (git), including branching and merging strategies.
• 2+ years of experience working with AWS infrastructure and platform services.
• 2+ years of experience with cloud automation tools (Ansible, Chef).
• Exposure to container services on AWS: Kubernetes, ECS, and EKS.
• A proactive eye for what can be made more reliable — and the follow-through to make it so.

You will be preferred if

• Expertise across multiple cloud providers: Amazon Web Services, Microsoft Azure, Google Cloud Platform.
• AWS Solutions Architect Professional or Associate certification.
• AWS DevOps Professional certification.
