Job summary

Fortastra Corporation is seeking a Sr. Avionics Engineer to design and deliver spacecraft avionics hardware and embedded systems through the full product lifecycle—from concept and architecture to PCB bring-up and integration on flight hardware.

This hands-on role emphasizes end-to-end ownership of boards, subsystems, and interfaces, collaborating with software, mechanical, and systems engineers to ensure flight-ready reliability.

Qualifications

• BS or MS in Electrical/Computer Engineering or related field.
• 5+ years designing electrical/avionics hardware through full lifecycle.
• Strong EE design: schematic capture and PCB for complex boards.
• Hands-on board bring-up: firmware flashing, interface testing, bench debugging.
• Experience with CAN/SPI/I2C/UART; Linux toolchains for hardware bring-up.

Responsibilities

• Own avionics hardware lifecycle from concept to flight-ready integration.
• Design flight computers and support boards with processors, memory, and interfaces.
• Select and integrate MCUs/SoCs, FPGAs, memories, sensors, and transceivers.
• Define board interfaces and buses: CAN, SPI, I2C, UART, Ethernet, SpaceWire.
• Develop ICDs for connections to GNC, power, propulsion and payload subsystems.
• Bring up boards in lab, write test firmware, debug hardware issues.
• Collaborate with embedded software to integrate drivers and health monitoring.
• Contribute to power architecture, protections, and load management.
• Apply design-for-test and design-for-reliability principles for flight qualification.

Job description

You’ll join Fortastra’s Engineering Division, responsible for the design, development, and test of flight systems across our autonomous spacecraft portfolio. The avionics function owns the electrical and computing backbone of the vehicle - flight computers, sensor interfaces, power distribution, and communications that enable autonomous operations in complex orbital environments.

The Role

Fortastra is seeking a Sr. Avionics Engineer to design and deliver spacecraft avionics hardware and embedded systems through the full product lifecycle from concept and architecture, through PCB design and bring-up, to integration on flight hardware. This is a hands‑on design engineering role for an Electrical Engineer who enjoys owning boards and systems end‑to‑end rather than specializing narrowly in analysis or test.

You will architect avionics subsystems, design PCBs, select components, and bring up hardware in the lab. While spacecraft experience is ideal, we are also open to candidates from automotive EVs, robotics, and defense who have strong EE design backgrounds and have shipped mission‑critical hardware.

Key Responsibilities

• Own the full lifecycle of avionics hardware: concept, architecture, schematic capture, PCB layout review, bring‑up, integration, and support to flight.
• Design flight computers and support boards, including processor, memory, power management, sensor/actuator interfaces, and communications interfaces.
• Select and integrate electrical components (MCUs/SoCs, FPGAs, memories, sensors, transceivers, power devices) appropriate for reliable operation in demanding environments.
• Define and implement board‑level interfaces and data buses (e.g., CAN, SPI, I2C, UART, Ethernet, SpaceWire) across the spacecraft avionics network.
• Develop and maintain Interface Control Documents (ICDs) for avionics connections to GNC, power, propulsion, and payload subsystems.
• Bring up new boards in the lab: write simple test firmware, debug hardware issues, and validate functionality using oscilloscopes, logic analyzers, and other instrumentation.
• Collaborate with embedded software and flight software engineers to integrate low‑level drivers, bootloaders, and health monitoring with the hardware you design.
• Contribute to power architecture and distribution within avionics assemblies, including protections, filtering, and load management.
• Apply design‑for‑test and design‑for‑reliability principles so boards can be efficiently validated, qualified, and flown.

Qualifications and Skills

• B.S. or M.S. in Electrical Engineering, Computer Engineering, or a closely related discipline.
• 5+ years of experience as a design engineer owning electrical/avionics hardware through its full lifecycle (spacecraft, automotive EVs, robotics, defense, or similar domains).
• Strong EE design experience, including schematic capture and PCB design/review for complex digital and mixed‑signal boards.
• Hands‑on experience bringing up boards: flashing firmware, exercising interfaces, and debugging hardware at the bench.
• Proficiency with embedded systems and common serial buses (e.g., CAN, SPI, I2C, UART), and familiarity with data acquisition or telemetry systems.
• Experience with C/C++ and Python in Linux‑based environments for hardware bring‑up, test automation, or tooling.
• Familiarity with FPGA‑based designs is a plus (RTL design, integration, or constraints), but not required.
• Experience in at least one mission‑critical domain (spacecraft, launch vehicles, automotive EVs, robotics, defense, or industrial control).
• Comfort working across disciplines and collaborating closely with software, mechanical, and systems engineers.

Requirements

• 5 days on‑site in Torrance, CA

Why Fortastra

We are a small, high‑impact team building the next generation of autonomous orbital control systems for national security space. At Fortastra, leaders own outcomes from first principles through flight and directly shape the future of resilient, mission‑critical spacecraft autonomy.

FORTASTRA TALENT & CULTURE PRINCIPLES

Values Driven by First Principles

We value engineers and operators who prioritize sound judgment, candor, technical rigor, bias for action, and intellectual honesty over corporate consensus. We care about the caliber of the system you build and the speed at which you solve problems.

Talent Density Over Headcount

A high‑performing startup is built on dense talent, not organizational bloat. A single exceptional engineer designs, tests, and delivers faster than a bloated committee. We intentionally maintain a lean, elite engineering crew where every contributor directly moves the needle on the mission.

We hire domain experts to execute, not to micromanage them. You own your systems end‑to‑end, from initial architecture and hardware design to testing and deployment. With absolute ownership comes the responsibility to deliver mission critical reliability.

Mission Context Over Bureaucracy

The best execution happens when teams are provided clear technical objectives, constraints, and operational context, rather than rigid top‑down policies. We strip away red tape so builders can iterate, make decisions, and push hardware and flight software forward rapidly.

Disciplined Speed & Flight Rigor

We move fast because we test often and kill artificial bottlenecks, not because we cut corners. Rapid iteration on the test stand and in simulation is how we learn; an uncompromising flight‑readiness bar is how we earn trust. Precision without friction, speed without recklessness.

You don’t come to Fortastra to climb a corporate ladder or manage slide decks; you come to build complex, flight‑ready systems from day one. Growth here is organic, driven by the magnitude of technical challenges you solve and the trust you build across the team.

We take care of our employees so they can focus on what matters most: family, well‑being, and life outside of work.

Unlimited Paid Time Off so that you have the time you need to rest and recharge.

Comprehensive Healthcare: Medical, dental, and vision coverage for you and your dependents, because peace of mind starts with feeling cared for.

Equity: Share in Fortastra's success with equity in the company you're helping build.

401(k): A 401(k) plan to help you invest in your future and plan for what's ahead.

Social Events: Regular social events, team outings, and company-sponsored activities that make this a place people are glad to be part of.

The pay range for this role is $130,000.00 - $170,000.00. Where an offer falls within that range depends on factors like your qualifications, experience, location, and interview performance, which we weigh against the market rate for the position.

This position is located at a facility subject to the International Traffic in Arms Regulations (ITAR). Access requires that you qualify as a "U.S. Person" as defined under 22 CFR 120.62. A U.S. Person is a U.S. citizen, U.S. national, lawful permanent resident ("green card" holder), or a protected individual (such as an asylee or refugee).

Are you a U.S. Person as defined above?

Will you now or in the future require the company to commence ("sponsor") an immigration case in order to employ you (for example, H-1B or other employment‑based visa status)? This is sometimes called "sponsor" for an employment visa/status.
