Senior Software Engineer, Software Platform
About the role 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. Responsibilities 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. Qualifications BS/MS in Computer Science, Engineering, or related field OR equivalent industry experience. 8+ years of software engineering experience, with strong proficiency in Python, C++, or Rust, in production environments. Experience in distributed systems, backend services, or platform development with hands-on depth in Kubernetes, Terraform, and AWS. Demonstrated experience building and operating mission-critical services with uptime, reliability, and performance requirements Knowledge of cloud-native infrastructure (e.g., containers, service orchestration, observability stacks). Strong debugging, profiling, and code optimization skills. Experience mentoring junior engineers or leading medium to large technical initiatives. Nice-to-have Skills Comfort working in a highly interdisciplinary environment with engineers, operators, and domain specialists. Familiarity with real-time data processing pipelines or high-throughput systems. Experience with CI/CD pipelines, infrastructure-as-code, or automated deployment workflows. Contributions to open-source projects or a track record of technical writing and knowledge sharing. Salary The salary range for this role is $184,000 - $208,000, plus a competitive equity grant and comprehensive benefits package. Final compensation will be determined based on skills, qualifications, experience, and geographic location as assessed during the interview process.
