Sr. Software Engineer - Chassis Tester Software

Application close date:
Applications will be accepted on an ongoing basis until the requisition is closed.

At Blue Origin, we envision millions of people living and working in space for the benefit of Earth. We're working to develop reusable, safe, and low-cost space vehicles and systems within a culture of safety, collaboration, and inclusion. Join our team of problem solvers as we add new chapters to the history of spaceflight!

This role supports the development and operations of New Glenn, a single-configuration, heavy-lift orbital launch vehicle capable of routinely carrying people and payloads to low-Earth orbit, geostationary transfer orbit, cislunar, and beyond. Its first stage is fully reusable, and the vehicle was designed from the beginning to be human-capable.

New Glenn is Blue Origin's orbital launch vehicle, and all avionics equipment that flies on it must be verified before it leaves the ground. As part of a hardworking team of engineers, you will be a senior technical contributor on the Chassis Tester Software team - the engineers who build the software stack that makes that verification possible. You will work on verification systems and be responsible for requirements, design, implementation, integration and testing of various software components and tools critical for the success of New Glenn's mission.

This is not a test automation role in the traditional sense. You will write Linux instrument drivers, architect hardware-in-the-loop test frameworks, build the operator-facing tools that run on the test floor, and own the automated result-checking infrastructure (Themis) that determines pass/fail for flight‑critical hardware. Your software is the last line of defense before hardware ships.

At Level 4, you set technical direction, make architectural decisions, and are accountable for the quality and reliability of the entire software stack.

• Design and implement production-quality Linux software drivers for test instruments - power supplies, DMMs, oscilloscopes, signal generators, DAQ systems - communicating over SCPI, VISA, serial, USB, and Ethernet
• Own the full driver lifecycle: characterization, implementation, integration testing, and documentation
• Work directly with avionics hardware engineers to understand instrument behavior, define operating envelopes, and validate driver correctness against hardware specs
• Architect and extend automated test execution frameworks and Themis, the team's result‑checking framework
• Implement check logic, pass/fail criteria, limit management, and structured report generation for acceptance and qualification test campaigns
• Own and evolve the Platform Integration Layer common framework and its platform integrations
• Design networking architecture for multi‑instrument, multi-UUT test configurations
• Build and maintain deployment automation (Ansible‑based role architecture) for test system configuration management
• Drive technical debt reduction: decouple legacy behaviors, standardize interfaces, and maintain a clean common codebase
• Design and implement operator‑facing applications - GUI tools and/or CLI interfaces - that allow test engineers and technicians to configure, execute, monitor, and review avionics test campaigns
• Prioritize usability, reliability, and clear feedback for non‑software users operating in a fast‑paced test environment

• B.S. in Computer Science, Electrical Engineering, Computer Engineering, or related field
• 8+ years of professional software engineering experience
• Expert‑level Python - you write clean, testable, maintainable Python and hold others to the same standard
• Proven experience developing software on Linux - process management, file system, systemd, shell scripting
• Experience with the networking stack - socket programming, UDP/TCP telemetry and command transport, packet capture and parsing, network reliability handling and configuration
• Hands‑on experience writing hardware interface software - instrument drivers, SCPI/VISA communication, or equivalent embedded/hardware‑adjacent development
• Experience with automated test frameworks (pytest or equivalent) including fixture design, parametrization, and…
