Flight Software Engineer II

About the Team:

The Integrated Software team is responsible for developing a wide array of software across the entire company. This includes controlling the rocket from launch pad to orbit, providing real-time control systems for engine testing, structures testing, and launch facilities, and lastly (but certainly not least) creating our factory of the future with our proprietary 3D printing technology. This team is at the forefront of driving Relativity Space towards our mission of a multiplanetary future, from changing how we manufacture rockets to how we fly them.

About the Role:

As a Flight Software Engineer II, you will have a major role in the full life cycle of Flight Software from development, integration to the commissioning and support of test and launch operations. You’ll work closely with GNC engineers to integrate complex algorithms for vehicle ascent and re-entry, descent and landing, and closely with Embedded Software Engineers and Avionics to integrate vehicle sensor data such as GPS, IMU, Radar, and to control vehicle equipment such as valves, thrust vector controls, and landing grid fins.

This role is expected to be on-site 3x a week in our Long Beach, CA headquarters.

• Write concise documentation such as Concept of Operations, Interface Control Documents, and Software Design Documents.
• Develop core flight software with a strong focus on meeting system and performance requirements such as latency, allowed jitter, and control frequency.
• Develop telemetry system that prioritizes, filters, stores and forwards, and encodes/decodes telemetry to RF format, and routes that data through ground stations and to data centers.
• Support the development and integration of testing infrastructure such as HITL (Hardware-In-The-Loop) and HOOTL (Hardware-Out-Of-The-Loop) and physics and fluid sims.
• Build automated unit, integration and system level tests in CI/CD.
• Focus on maximizing the team’s velocity by defining processes, best practices, integrating modern tools and technologies.

About You:

• An undergraduate or graduate degree in a relevant engineering discipline (Electrical Engineering, Computer Engineering, Computer Science, Aerospace Engineering) with 2+ years experience of production development experience.
• Professional experience and technical expertise delivering production-level and real time embedded software.
• Experience in Rust, C++, and/or other system languages, as well as algorithms and data structures.
• Experience in Linux Operating System concepts such as memory management, CPU shielding, scheduling, etc.
• Experience in networking concepts such as TCP/IP, UDP.
• Experience with software development processes including: source control, bug tracking, and CI/CD.

Nice to haves, but Not Required:

• Familiarity with developing fault and failure tolerant system and knowledge of voting and internal state synchronization.
• Experience with systems-level programming like synchronization primitives, memory management, etc.
• Experience with different inter-process communication methods.
• Experience with message passing protocol such as flatbuffer or protobuf.
