Senior Software Engineer

Job summary

Ont*** is a leader in process control, combining global scale with an expanded portfolio of leading-edge technologies that include: 3D metrology spanning the chip from nanometer-scale transistors to micron-level die-interconnects; macro defect inspection of wafers and packages; metal interconnect composition; factory analytics; and lithography for advanced semiconductor packaging.

Benefits

Qualifications

• Required
• Strong coverage of most below; missing one or two is fine if you bring the fundamentals.
• BS in Computer Science or equivalent practical experience, with 3+ years in DevOps / SRE in production.
• Demonstrated ownership of CI/CD at scale, ideally GitHub Actions with cloud-hosted VM runners built from custom images (Packer / Azure Image Builder / EC2 Image Builder) and OIDC to cloud.
• Experience with GPU-enabled cloud VMs and GPU passthrough for test workloads.
• Working knowledge of C#, MSBuild, NuGet, and .
• NET across the range used here (.
• NET Framework 4.8 through .
• NET 9, plus .
• NET Standard 2.0), including internal NuGet feeds and large package artifacts, and of C++ on Windows (.vcxproj, MSVC, vcpkg / CMake).
• Comfortable extending .
• NET builds to Linux.

Responsibilities

• You will be joining a sharp, tight-knit engineering organization that shares knowledge generously, challenges each other in good faith, and has a lot of fun solving hard problems together.
• Platform: build, test, sign, and ship
• Design and maintain shared GitHub Actions CI/CD (reusable workflows, composite actions, matrix builds) that product teams compose into their own pipelines, with first-class C# / MSBuild / .
• NET and C++ / vcpkg / CMake build paths.
• Own the NuGet story end-to-end: internal feed, large internal package artifacts, versioning, retention, and CI restore performance.
• Design and operate the runner fleet: cloud-hosted Windows-first (plus Linux) VMs running containerized CI/CD jobs from custom images (Packer / Azure Image Builder), including a GPU-passthrough image.
• Pick the right orchestrator for the workload, keep toolchains pinned and reproducible, and own the operational details (driver / CUDA pinning, runner registration, ephemeral vs warm pools).
• Own packaging, signing, and release plumbing: WiX (v4 / v5+) MSI templates, NuGet packaging, Authenticode signing (HSM / cloud signing), SemVer / changelog automation, install / upgrade scaffolding.
• Provide the test integration surface in CI (VSTest / MSTest / NUnit / xUnit for .
• NET, plus the C++ test frameworks in use, including hardware-in-the-loop where applicable).
• Build automation and observability tooling (Python, PowerShell, Bash) and manage the runner and image fleet as infrastructure as code so it is reproducible, reviewable, and auditable.
• Tool choice is open; propose the right one when the need is real.
