Platform Engineer (FedD160)

EMPLOYER IS A CONTRACTOR FOR THE U.S. GOVERNMENT. THIS POSITION WILL REQUIRE U.S. CITIZENSHIP.

Role Description

Defense Unicorns is seeking a Platform Engineer to join our platform team — a combined DevOps and Site Reliability Engineering team responsible for the development, maintenance, and reliability of a cloud-based platform environment. The ideal candidate is a strong problem-solver with hands-on experience in Kubernetes, cloud infrastructure, and CI/CD, and is motivated by building and improving the systems that other teams depend on.

In this role, you will work across infrastructure as code, automated deployments, identity and access management, monitoring, and CI/CD pipelines. You will serve as a bridge between application teams and the platform, advocating best practices and helping ensure that the platform is reliable, secure, and scalable. You should be comfortable operating in ambiguity, contributing to documentation and standards where they exist, and building them where they don’t.

Responsibilities

Build, maintain, and improve Kubernetes clusters and containerized application deployments across cloud environments (AWS, EKS, RKE2)

Develop and manage infrastructure as code (IaC) to provision and configure platform resources consistently and repeatably

Own and improve CI/CD pipelines, including GitLab CI configuration, runner deployments, and automated build and deployment workflows

Support identity and access management through tools such as Keycloak, including user onboarding, role configuration, and troubleshooting.

Implement and maintain monitoring, alerting, and logging to ensure platform health and support incident investigation

Manage certificate lifecycle operations, including renewal of public certificates and related automation

Contribute to platform security posture through container security practices, Iron Bank image compliance, and support for ATO processes

Collaborate with application teams to troubleshoot deployment issues, broken pipelines, and platform integration problems

Write and maintain technical documentation, runbooks, architecture decision records (ADRs), and operational standards

Influence the strategic vision by contributing to the strategic planning that aligns technological advancements with the mission objectives.

Participate in on-call rotations and support platform incidents in a tier 2 role

Mentor and support junior engineers through pairing, code reviews, and knowledge sharing

The listed responsibilities are not exhaustive and additional responsibilities may be assigned based on the evolving needs of the organization. We are seeking a dynamic individual who is able to adapt and take on new responsibilities as they arise.
