Galactic Resource Utilization Space, Inc. (GRU Space)

Your circuit board will wake up on the lunar surface next year. You’ll design the electronics and flight software that bring our 2027 lunar payload to life: commanding the ISRU brick fabrication process, inflating a habitat bladder, and getting data back to Earth.  What you’ll do: Design the avionics stack: controller boards, power distribution, sensor interfaces and valve actuation electronics. Write the flight software for payload sequencing, closed-loop process control, and fault management. Own the electrical interface to the CLPS lander (power, data, commanding, telemetry formatting). Select and qualify components for the lunar radiation and thermal environment. Design and build harnessing, including a lunar umbilical cord exposed on the Moon for our deployable payload. What we’re looking for: Experience designing mixed-signal PCBs from schematic through layout, fabrication, and bring-up (full-cycle). RS-485 / serial protocol design: you can write a protocol ICD and define baud rate, framing, CRC, and fault handling from scratch. Flight software in C/C++ on microcontrollers: state machines, FDIR, watchdog logic, closed-loop control. Familiarity with spaceflight-adjacent standards for wiring, grounding, and EMI/EMC. Power electronics: 28 Vdc conditioning, inrush limiting, motor driver integration, and power budget analysis. Harness design: MIL-STD-38999 connectors, EMI/EMC compliance, thermal-rated wire and insulation (Kapton/PTFE), shielding continuity. Comfort operating across the hardware/software boundary: you can debug a board with an oscilloscope and a JTAG probe. You’ve built flight hardware before Excellent communication skills Must haves: Experience architecting an avionics system from scratch that flew into space: you've taken a design from concept to launch and can point to it. Full-cycle PCB design: schematic through layout, fab, bring-up, and in-system debug. Nice to haves: Experience writing ICDs and technical documentation delivered to a vehicle or launch provider. Familiarity with actuator drive electronics (brushed DC motors, NEA/pyro devices) or compressed-gas systems. Comfortable interfacing with mechanical design teams. Onboard data storage design: NAND flash, wear leveling, downlink queue management. Experience with radiation-tolerant or rad-hard component selection. You can drink from the fire hose. ITAR Requirements To conform to U.S. Government space technology export regulations, including the International Traffic in Arms Regulations (ITAR), you must be a U.S. citizen, lawful permanent resident of the U.S., protected individual as defined by 8 U.S.C. 1324b(a)(3), or eligible to obtain the required authorizations from the U.S. Department of State.

You’ll own the environmental verification for our 2027 lunar payload, ensuring it withstands launch loads, landing shock, vacuum, and the thermal extremes of the lunar surface. This role is the analytical backbone of the team. What you’ll do: Build and maintain the thermal model for the full payload, electronics thermal management, and lunar surface boundary conditions. Run structural FEA for launch vibration, acoustic loads, landing shock, and handling/transport. Drive design trades with the mechanical and avionics engineers: your models inform their decisions on materials, mounting, insulation, and heat rejection. Support thermal-vacuum and vibration test campaigns: predict performance, compare to test data. What we’re looking for: Strong FEA background (ANSYS, Nastran, Abaqus, or similar) for both structural and thermal analysis. Experience with spacecraft or launch vehicle thermal environments: conduction networks, radiation exchange, transient analysis. Understanding of structural dynamics: random vibration, shock spectra, modal analysis, and how they drive hardware design. Ability to make engineering judgments under uncertainty: Class D means we accept more risk, but that requires knowing where the risk actually is. You’re using the latest AI tools every day (i.e., Opus 4.6/GPT 5.4, in appropriate harness) to massively increase your output and do things you otherwise couldn’t. You’ve built flight hardware before. If you want to maximize the probability that humanity becomes interplanetary in your lifetime, apply and share a portfolio of the technical work you’re most proud of.

Your product will land on the Moon next year. You’ll design, build, and test our 2027 Lunar Payload: the one that manufactures humanity’s first bricks on the Moon and deploys an inflatable habitat bladder. This is hands-on, full-lifecycle hardware engineering at a pace most aerospace companies can’t keep up with. What you’ll do: Own the mechanical design of the payload from concept through flight hardware. Rapidly prototype, test, break things, and iterate. Manage ICD with the lunar lander provider and be the primary point of contact. Run and interpret structural/mechanism analysis to support design trades. What we’re looking for: Deep fluency with CAD and FEA tools: you think in 3D and can back it up with analysis. Experience designing spaceflight hardware end-to-end (build, test, deploy). Comfort with mechanisms: actuators, seals, deployables, pressure systems, end effectors, and more.
