<h2><strong>About Shift5</strong></h2> <p>Shift5 delivers operational intelligence for onboard OT across defense, aerospace, and commercial transportation fleets. We capture and analyze databus data to detect anomalies, predict failures, and secure critical infrastructure against cyber threats.</p> <h2><strong>The Role & Team</strong></h2> <p>The Platform Engineering team owns four core capabilities: <strong>Operating Systems</strong> (BaseOS, Manifold, Yocto), <strong>Cloud & Infrastructure</strong> (AWS/GovCloud to edge), <strong>Developer Experience</strong> (CI/CD guardrails, internal tooling), and <strong>AI Enablement</strong> (secure AI orchestration and tooling).</p> <p>As <strong>Principal Platform Engineer</strong>, you are the senior-most individual contributor on the team, serving as the primary technical anchor for architecture and a key multiplier for the engineering org. You will drive overall technical strategy, mentor senior engineers, and step into direct team leadership or people management as needed.</p> <h2><strong>What You'll Do</strong></h2> <ul> <li><strong>Release Engineering:</strong> Architect, develop, and operate end-to-end release infrastructure and GitOps delivery pipelines using tools like Atlantis, ArgoCD, Earthly Lunar, GitHub, and internally developed tools.</li> <li><strong>Cloud Infrastructure</strong>: Architect and manage a complicated AWS estate spanning commercial and govcloud using services like EKS, RDS, S3, VPC, Transit Gateway, etc.</li> <li><strong>Supply Chain Security & Compliance:</strong> Lead artifact security (Harbor, Cosign, Vault Transit Engine) and build automated, compliance-by-default pipelines (NIST controls, SBOM generation) to eliminate program friction.</li> <li><strong>OS Lifecycle & AI Enablement:</strong> Support hardware OS image builds (Yocto, Manifold) and productionize internal AI gateways, RAG tooling, and developer AI workflows (Cursor).</li> <li><strong>Technical & Team Leadership:</strong> Author RFCs/design docs, run architecture reviews, plan roadmaps, and mentor mid/staff-level engineers. Provide direct management (1:1s, hiring, performance reviews) during transitions or scale.</li> <li><strong>Cross-Functional Collaboration:</strong> Partner with security, embedded, and field teams to ensure seamless delivery across airgapped and edge environments.</li> </ul> <h2 data-path-to-node="8">What Success Looks Like</h2> <ul> <li><strong>Predictable Delivery:</strong> Release engineering is seamless, observable, and fully trusted across teams.</li> <li><strong>Automated Security:</strong> Compliance evidence and SBOMs are generated natively in CI/CD without manual overhead.</li> <li><strong>Governed AI:</strong> AI tooling is securely integrated, well-documented, and actively adopted by developers.</li> <li><strong>Team Growth & Resilience:</strong> Engineering standards elevate across the org, priorities remain clear, and team leadership operates without single points of failure.</li> </ul> <h2 data-path-to-node="10">What We’re Looking For</h2> <p><strong>Required:</strong></p> <ul> <li><strong>10+ years</strong> in software/platform engineering, with <strong>5+ years</strong> managing production infrastructure at scale.</li> <li><strong>Technical & People Leadership:</strong> Proven track record leading projects, designing architecture, mentoring engineers, and readiness (or prior experience) for direct people management.</li> <li><strong>Cloud & Modern Delivery:</strong> Hands-on mastery of Kubernetes, ArgoCD, GitHub Actions/Earthly, and Infrastructure as Code (Terraform/OpenTofu, AWS/GovCloud).</li> <li><strong>Supply Chain Security:</strong> Strong background in artifact registries, container signing (Cosign/Sigstore), Vault, and SBOM generation.</li> <li><strong>Clearance:</strong> Ability to obtain and maintain a U.S. Security Clearance (<strong>U.S. Citizenship required</strong>).</li> </ul> <p><strong>Preferred:</strong></p> <ul> <li>Background in defense, aerospace, or regulated environments (NIST 800-53, IL4/IL5, CMMC).</li> <li>Embedded Linux/OS experience (Yocto, SLE Micro) and airgapped/edge deployment models.</li> <li>Experience deploying internal AI/LLM infrastructure (RAG, model gateways, governance).</li> <li>Scripting proficiency in Go, Python, and Bash.</li> </ul> <h2><strong><span data-contrast="none">Compensation & Benefits</span></strong></h2> <ul> <li style="font-weight: bold;"> <p><strong>Base Salary: $255,000 - $280,000</strong></p> </li> <li style="font-weight: bold;"> <p><strong>Bonus program and equity in a fast-growing startup</strong></p> </li> <li style="font-weight: 400;"> <p><span style="font-weight: 400;">Competitive medical, dental, and vision coverage for employees and their families</span></p> </li> <li style="font-weight: 400;"> <p><span style="font-weight: 400;">Health Savings Account with annual employer contributions</span></p> </li> <li style="font-weight: 400;"> <p><span style="font-weight: 400;">Employer-paid Life and Disability Insura
