Muonspace Senior Software Engineer at Muonspace builds and operates scalable, resilient software platform systems supporting internal tooling and customer-facing products. The role requires cross-functional collaboration and ownership from concept through deployment.

Responsibilities

Muon is looking for a Senior Software Engineer to join our Software Platform team. This team builds and operates the paved roads (CI/CD, Kubernetes, Terraform, Bazel, AWS, IAM, data infrastructure, and more) that underpin both our internal tooling and the production systems behind customer-facing products such as Muon Mission Command.
The Software Platform team is critical to the overall growth and success of Muon's software engineering organization: as the number of product teams, services, and customers expands, the leverage this team creates, through reduced cognitive load, eliminated toil, and self-service Golden Paths, directly determines how fast the rest of engineering can move.
This position is hybrid and requires working on-site in our San Jose, CA office three days per week.
Design, build, and evolve high-performance systems that are scalable, resilient, and reliable.
Work across the stack, and cross-functionally to deliver end-to-end platform capabilities.
Contribute to architectural decisions that shape the long-term direction of our core systems.
Identify and resolve bottlenecks, performance issues, and systemic risks in production environments.
Partner with cross-functional teams to translate business and product needs into well-crafted technical solutions.
Participate in code reviews, technical design discussions, and knowledge sharing across teams.
Take ownership of features from concept through deployment and ongoing operation.
