Senior DevOps Engineer

Responsibilities:

Infrastructure Architecture — Own the design and evolution of Merlin's cloud and on-premises infrastructure across AWS and Azure. Make architectural decisions that balance cost, reliability, security, and compliance.
Infrastructure as Code — Lead Terraform-based IaC initiatives across the organization. Establish standards, review infrastructure changes, and drive the team toward fully code-managed environments.
CI/CD Platform Ownership — Set the technical direction for CI/CD pipelines across multiple interdependent systems using GitHub Actions. Drive reliability, performance, and maintainability improvements at the platform level.
Security & Compliance — Own DevSecOps tooling — security scanning (SAST, SCA, container scanning), SBOM generation, and artifact integrity. Ensure pipelines meet contractual and regulatory obligations including export control and CDRL requirements.
Cloud Environment Management — Manage cloud infrastructure across commercial and government-aligned environments, including Azure GCC High or equivalent FedRAMP/DoD-compliant platforms.
Deployment Automation — Design and improve deployment pipelines to test systems, bench hardware, and flight test aircraft using Docker, Debian packaging, Ansible, and JFrog Artifactory.
Cross-Team Collaboration — Partner with flight software engineers, systems engineers, IT, and leadership to ensure infrastructure supports program priorities. Communicate clearly and document your work to drive adoption across teams.

Qualifications:

• 3–5 years of experience in DevOps, Platform Engineering, Site Reliability Engineering, or a related role

• Deep expertise with Infrastructure as Code — Terraform required; CloudFormation or Pulumi also acceptable

• Strong hands-on experience with AWS and Microsoft Azure — AWS is our primary cloud for engineering infrastructure; both platforms are active parts of the role

• Strong experience with CI/CD platforms — GitHub Actions preferred; Jenkins, GitLab CI, or CircleCI also acceptable

• Solid experience with Linux system administration (Ubuntu preferred)

• Proficiency with Docker for building, publishing, and deploying container images

• Strong scripting skills in Python and Bash

• Experience with security and compliance tooling — SAST, SCA, SBOM generation, container scanning, or artifact signing

• Experience with configuration management tools — Ansible preferred; Chef, Puppet, or similar also acceptable — including managing software and configuration state across physical systems and embedded hardware targets (e.g., bench hardware, flight test aircraft), not just cloud or server infrastructure

• Familiarity with artifact repositories — JFrog Artifactory, Nexus, or similar package/container registries

• Strong problem-solving skills, attention to detail, and ability to work independently with minimal direction

• Excellent communication and documentation skills

Nice to Have:

Experience with government-aligned cloud environments — Azure Government, GCC High, or equivalent FedRAMP/DoD-compliant platforms
Experience working in GCC High (Microsoft Azure Government Community Cloud) or other FedRAMP/DoD-compliant cloud environments
Experience with Debian packaging (dpkg, dch, Launchpad PPAs, or S3-hosted APT repos)
Experience with software products that include a physical systems component — aircraft, robotics, medical devices, autonomous vehicles, or similar
Familiarity with distributed pub/sub frameworks (e.g., ROS2) and underlying middleware such as DDS and Zenoh
Knowledge of networking fundamentals and network security best practices
Experience working in a regulated environment (aerospace, automotive, medical, defense) where traceability and process compliance matter
Familiarity with SITL (Software-in-the-Loop) or HIL (Hardware-in-the-Loop) simulation infrastructure
Familiarity with dev containers and containerized development environments
Familiarity with orchestration techniques for automated regression and simulation-level integration testing (e.g., ReSim or similar frameworks)
