Avionics Systems Engineer (All Levels)

About the Role

Astrolab is The Lunar Operations Company. We design and build the systems and hardware the lunar economy will come to depend on — rovers, power, and data networks for sustained operations on the Moon.

As an Avionics Systems Engineer at Astrolab, you will define the requirements, architecture, and implementation of avionics systems on our planetary rovers. You will own the electrical architecture at the vehicle level, spanning power distribution, data networks, harnessing, and the interfaces between avionics units. You will represent the avionics team in vehicle-level trades with mechanical, software, and thermal teams. You will serve as Responsible Engineer for avionics system design and performance, carrying it from requirements definition through integration, verification, and operations on the lunar surface. This posting covers entry-level through staff-level positions, and leveling will be commensurate with experience.

Key Responsibilities

• Architecture & Requirements: Define avionics system architecture and electrical architecture at the vehicle level, including power distribution, grounding, data networks, and harnessing. Write, flow down, and verify requirements at the system and component level.
• System Trades: Lead design trades and sensitivity studies to select architectures that are robust, fault-tolerant, and meet mission requirements. Represent the avionics team in vehicle-level trades with mechanical, software, and thermal teams.
• Interfaces: Create and maintain technical documentation including system diagrams, schematics, interface control documents, procedures, and test and anomaly reports. Own electrical interfaces between avionics units, payloads, and ground systems.
• Verification & Test: Develop design verification, qualification, and acceptance test plans, and coordinate with avionics hardware, manufacturing, and test engineers to execute them. Help develop and operate HIL testbeds to verify functionality before vehicle integration.
• Integration & Operations: Support assembly, integration, and test (AIT), write and execute vehicle-level electrical functional validation procedures, and support launch campaigns and lunar surface operations.
• Anomaly Resolution: Support integration testing, production issue dispositions, and troubleshooting of failures, using root cause techniques such as fault tree and fishbone analysis, and manage overall avionics system risk.

Requirements & Tech Stack

• Bachelor's degree in a science, technology, engineering, mathematics (STEM) related field.
• Experience with aerospace component or system development, testing, integration, or operations.
• Experience with electrical test equipment including oscilloscopes, logic analyzers, signal generators, electronic loads, and multimeters.
• Ability to interpret electrical schematics.
• For senior and staff levels: Experience leading development of avionics architectures for current and future vehicles, developing schedules and system-level test and operations plans, and mentoring engineers.

Qualifications (Preferred)

• Experience with spacecraft or launch vehicle avionics systems design, development, production, test, and operations.
• Experience with requirements writing, flow-down, and verification using systems engineering tools and processes.
• Experience performing trade studies and sensitivity studies.
• Experience with spacecraft power system engineering, including power budgeting, distribution, and grounding architecture.
• Experience with digital communication protocols and vehicle networks including RS-422, RS-485, CAN, or Ethernet.
• Experience with HIL testbed system development, and programming in Python, C, or C++ for test and automation.
• Familiarity with FMECA, fault tolerance and isolation design, and failure modes of spaceflight electrical components.
• Familiarity with SMC-S-016, MIL-STD-810, or other environmental testing standards, including shock, thermal, burn-in, TVAC, vibration, and EMI/EMC testing.
