Principal Platform Engineer (DevOps)

Platform Development & Technical Leadership

You will be responsible for Platform Development & Technical Leadership:

• Own the design and architecture of platform capabilities across AWS Organizations, GitHub Enterprise, Terraform Cloud, and JFrog Artifactory — balancing developer experience with security and compliance requirements.
• Architect and implement complex AWS Organizations structures: multi-account governance, secure account configuration, SCP strategy, permission boundaries, and account vending pipelines that scale with IDEXX’s growth.
• Lead the design of GitHub Enterprise configurations, policies, and automation — ensuring the platform is both highly usable for developers and meets InfoSec and Compliance standards.
• Define Terraform Cloud platform standards: workspace architecture, Sentinel policy frameworks, module registry strategy, and state management patterns.
• Support engineering teams in adopting secure artifact and dependency hosting within JFrog Artifactory
• Write and review production-quality Python — setting the standard for code quality, testing practices, and maintainability on the team.
• Lead and participate in pair programming and code review; your engagement elevates the quality and design thinking of the whole team.
• Identify platform gaps and technical debt and drive initiatives to address them through the backlog and sprint process.

Mentorship & Team Growth

You Will Be a Mentor, Fostering Team Growth:

• Mentor and coach Senior and mid-level Platform Engineers — providing technical guidance, code feedback, and career development support.
• Model collaborative engineering practices: pairing, documentation, incremental delivery, and open communication.
• Help onboard new team members and accelerate their ramp-up on platform tooling, codebases, and team norms.

Agile Team Participation

You Will Engage With Internal Customer Partnerships:

• Partner closely with the Platform Lead Engineer and Platform Agile Practitioner to shape backlog refinement, define acceptance criteria for complex work, and ensure technical clarity before work enters a sprint.
• Collaborate with the Platform Engineering Manager and Platform Product Owner to influence prioritization of technically complex or high-impact work.
• Drive architectural discussions and lightweight design reviews within the team sprint cycle — keeping the team moving without creating heavyweight process.
• Break down ambiguous, cross-team platform problems into well-scoped deliverables.

Requirements

• 8+ years of experience in platform engineering, DevOps, or infrastructure software engineering, with demonstrated growth in scope and ownership over time.
• Subject matter expertise in CloudFormation and Terraform.
• Fluency in Python — you write it fluently, review it critically, and set the standard for quality and design on the team.
• Deep expertise with AWS Organizations: SCP strategy, account governance, landing zone design (Control Tower or equivalent), and multi-account security architecture.
• Advanced GitHub Enterprise administration experience: organization-wide policy design, GitHub Actions at scale, security configuration, and API-driven automation.
• Strong Terraform Cloud expertise: workspace and state architecture, Sentinel policy framework design, module publishing, and governance patterns.
• Track record of mentoring or growing other engineers — technically and professionally.
• Proven ability to handle ambiguous, cross-team problems independently and drive them to clear, well-implemented solutions.
• Strong agile collaboration skills: you know how to work within a sprint team, shape a backlog, and deliver iteratively without losing sight of long-term platform health.
• Excellent communication skills — you can engage confidently with engineers, managers, InfoSec, and Compliance teams alike.
• A collaborative mindset by default — you don’t go it alone, and you don’t let others go it alone either.
