Senior Software Engineer, Customer Solutions

San Jose, CA

About the role

Muon seeks a Senior Software Engineer, Customer Solutions to join our Software team. This engineer will help Muon's customers integrate their payloads and software before launch, guiding them through the software development kit, payload accommodation guide and best practices for deploying their instruments in a constellation of spacecraft.

You will serve as a technical expert and guide for the customer throughout the early phases of their mission, ensuring that they can test their code and payload long in advance of launch. You will set up appropriate simulations and tests with them to help them gain confidence in what will happen on orbit. You will ensure a seamless transition such that the systems can work the same in test as they will work in orbit, allowing the customer to much more quickly get real data from their spacecraft.

This position is hybrid and requires working on-site in our San Jose, CA office three days per week.

Responsibilities

  • Own the engineering experience for external payload partners integrating with Muon's software platform, including how they can handle commanding, telemetry, payload management, fault detection and recovery, and data downlink.
  • Partner with Flight Software, Mission Engineering, and Systems Engineering to influence design and evolution of our payload interfaces.
  • Run customer-facing technical exchanges, design reviews, and integration test campaigns. Serve as the named software technical point of contact for payload partners.
  • Author and maintain the customer-facing developer guide, sample code, and reference applications for the customer-facing Payload Software Development Kit; contribute to the Payload Accommodation Guide.
  • Maintain up-to-date epics, estimate forward-looking work, and escalate roadmap changes or delays early.
  • Define and track metrics that matter for the customer payload-integration experience (e.g., integration cycle time, customer-blocking issue lead time) and manage OKRs for your area of responsibility.
  • Mentor newer software engineers; raise the bar for code quality, design review, and customer-facing documentation across the team.

Qualifications

  • B.S., M.S., or Ph.D. in Computer Science, Computer Engineering, Aerospace Engineering, or a related field — or equivalent experience.
  • Strong fluency in modern C++ and Python.
  • 7+ years of professional software engineering experience, including shipping software that external customers depend on.
  • Excellent coding and design skills.
  • Demonstrated experience designing and operating service interfaces (gRPC/protobuf or REST), file-transfer protocols, and structured telemetry pipelines.
  • Experience integrating software across organizational boundaries such as vendor SDKs, third-party hardware, or external customer code.
  • Excellent written and verbal communication.

Nice-to-have Skills

  • Working knowledge of Rust.
  • Spaceflight flight software experience, or other safety/mission-critical embedded software experience.
  • Direct experience integrating third-party payloads with a satellite bus.
  • Prior work building developer SDKs, customer-facing technical documentation, or partner-integration programs.
  • Familiarity with Linux-based real-time systems and embedded networking (Ethernet/CAN/serial) at the protocol level.
  • Experience in negotiation and customer alignment.

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.

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities.

Your decision to complete the form and your answer will not harm you in any way.
