DevOps Engineer

DevOps EngineerEngineering Infrastructure · On-site · Mid/Senior · Full-timeAbout us:At Majestic, we're re-architecting systems for the future of AI. We're on a mission to make AI ubiquitous by leveraging groundbreaking technologies. If you're passionate about deep tech and full stack AI, this is a chance to join our world-class team shaping the future of AI.Role Description:We are looking for an experienced DevOps engineer to own the developer infrastructure that the Majestic software stack rides on — CI/CD, dev environments, and internal deployments. You will be responsible for the pipelines that build and test our host SDK, execution runtime, embedded firmware, kernel libraries, and simulator end-to-end; for the dev containers and tooling engineers work in day-to-day; and for the internal sites and services the team relies on. Your work directly determines how fast every engineer at Majestic ships, and how confidently we tape out.What You'll Do:Own and evolve CI/CD across the codebase — selecting the CI system, building the pipelines that validate the full software stack end-to-end (including simulator-in-the-loop runs for firmware and kernels), and keeping them reliable as the team growsMake CI fast: cut build and test times for heavy targets through caching, artifact reuse, and self-hosted runner strategiesOwn the developer experience — dev containers, reproducible local setups, and the PR and code review workflow engineers ship through every dayOperate internal site and service deployments — dashboards, documentation sites, and the internal tools the team depends onStand up production-representative server systems in our dev environment so engineers can develop and test against what customers will eventually run — including provisioning, host OS setup, and keeping these shared systems healthy and available to engineers and CIContribute to observability — pipeline metrics, build health dashboards, flake trackingCollaborate with compiler, runtime, kernel, and hardware teams to make infrastructure fit how the org actually developsRequirements:What We're Looking For:3+ years (5+ preferred) operating production CI/CD systems for a real engineering orgDeep hands-on experience with at least one major CI system (Jenkins, Buildkite, GitHub Actions, GitLab CI, Concourse) — self-hosted runners, matrix builds, caching strategies, reusable pipeline patternsStrong Bazel experience, or strong enough build-system instincts to come up to speed fastStrong Linux, Bash, and PythonContainerized builds (Docker), artifact registries, dependency management across multiple languagesComfortable in repos with serious C++ build systems (CMake, LLVM-scale) and Python packagingNice to Have:Experience supporting ML, compiler, or systems teams (PyTorch, Triton, LLVM, MLIR)Cross-compilation toolchains, especially RISC-VSimulator- or emulator-driven CI (QEMU, SystemC, FPGA flows)Observability tooling for builds and pipelines (Grafana, Prometheus, OpenTelemetry)Background as a software engineer before moving into DevOpsExperience with agent-assisted pipelines and AI-augmented developer workflows
