we are looking for a Senior DevOps Engineer Platform Engineering.Responsibilities:-Design, build, and operate the internal engineering platform powering ' build, test, deployment, and security validation workflows at scale- Write and maintain production-grade Python and shell tooling that drives platform automation - this is a hands-on coding role, not just pipeline configuration- Architect and manage hybrid cloud/on-prem execution infrastructure, including large-scale Kubernetes runner pools across multiple AWS regions- Own and evolve CI/CD pipelines at scale using GitHub Actions, including reusable workflows, ARC-based runner orchestration, and build caching strategies (BuildKit, sccache, Valkey)-Operate and tune DinD environments (Sysbox, EBS/NVMe, overlay storage, MTU/networking) for build, test, and release workloads- Connect and manage self-hosted and on-prem runners, routing physical device (wbox) test jobs by site and device type- Implement DevSecOps controls including least-privilege IAM, OIDC, isolated runner groups, container signing, and automated security scans- Drive platform observability, cost optimization, and reliability improvements across the engineering infrastructure- Collaborate cross-functionally with hundreds of engineers to improve engineering velocity and release confidence- Take end-to-end ownership of complex infrastructure problems and drive them to resolutionRequirements:
- 5 years of hands-on DevOps experience with a strong software development background - prior development experience is a must- B.Sc. in Computer Science or equivalent practical experience- Strong programming skills in Python (or a similar high-level language); ability to write and own production tooling- Proven experience designing and building scalable systems, automation frameworks, and infrastructure as code using Terraform and Helm- Solid understanding of Linux, containers (Docker), and Git-basd workflows- Hands-on experience with CI/CD at scale using GitHub Actions or similar - including reusable actions, workflow design, and automation frameworks- Deep experience with hybrid cloud infrastructure (AWS and on-prem), including EKS, ARC, Karpenter, ECR, S3, Direct Connect, VPC endpoints, IAM/OIDC, and Secrets Manager- Experience operating spot and on-demand runner pools for builds, DinD tests, releases, and security scans across multiple AWS regions- Experience with DinD environments (Sysbox, EBS/NVMe, memory limits, overlay storage, MTU/networking) and build caching (BuildKit, sccache, Valkey)- Experience connecting on-prem/self-hosted runners and routing physical device (wbox) test jobs by site and device type- Experience implementing DevSecOps controls and improving platform observability, cost efficiency, and reliability- Platform & tooling familiarity: Kubernetes (EKS, on-prem) GitHub Actions ARC Karpenter Terraform Helm Docker/DinD Sysbox containerd BuildKit ECR S3 ElastiCache (Valkey) sccache Direct Connect VPC endpoints IAM/OIDC Secrets Manager self-hosted runnersSoft Sills:
- Strong system-level thinking and troubleshooting skills; able to diagnose and resolve complex infrastructure issues independently- Takes end-to-end ownership and drives problems to resolution without hand-holding- Excellent communication and cross-team collaboration skills; comfortable working alongside large engineering organizationsNice to Have / Advantage-Experience with Jenkis- Familiarity with GitHub merge queue- Experience with MinIO or on-prem S3 caching- Hardware-in-the-loop CI experience- MTU/VPC networking tuning expertise- Monorepo CI optimization experienceThis position is open to all candidates.
