About the role
Muon Space is looking for a Platform Engineer to own the shared technical foundation of our High Performance Compute (HPC) team. This is an engineering-track, individual-contributor role. You'll own the build flows, test environments, and delivery pipelines that turn FPGA and GPU engineering output into flight-ready artifacts, and the planning and reporting rhythm that keeps the team predictable across a growing portfolio of missions.
As Muon takes on more missions with more varied compute needs, your job is to keep the platform coherent while maximizing reuse across missions, minimizing variations, and making sure our delivery methods and planning methods evolve together.
This position is hybrid and requires working on-site in our San Jose, CA office three days per week.
Responsibilities
-
Platform, Build & Delivery
-
Maintain and evolve the technical build flows, test environments, and delivery and integration pipelines for both FPGA and GPU code, ensuring reproducible, reliable, and fast turnaround from commit to lab-ready artifact.
-
Own the toolchain environments (synthesis, simulation, cross-compilation, containerized builds) and keep them up-to-date, documented, and consistent across engineers.
-
Manage the complexity of delivering into a growing variety of future missions, actively working to keep mission-to-mission variations as small as possible, and promoting shared components.
-
Planning, Delivery & the Intersection Between Them
-
Operate at the intersection of delivery methods and planning methods, ensuring the way we plan reflects how we actually build and deliver, and that both evolve together as the team and mission portfolio grow.
-
Own the team's roadmap in Jira: keep it accurate and trackable at all times; enable on-demand snapshot reporting that shows progress, priorities, and resource utilization.
-
Partner with tech leads and engineers to estimate incoming work packages for upcoming missions and inbound requests from other teams and departments.
-
Establish and track planning-accuracy metrics and use them to improve estimation quality.
-
Publish weekly reports on the team's state of health: successes, risks, opportunities, blockers, and highlights: for team-internal and cross-company audiences and be the single source of truth for status, progress, and Jira reporting for the Onboard Compute organization.
