We are seeking a Senior Engineer, Embedded Software to join our rapidly growing team developing a revolutionary hydrogen fuel cell electric powertrain for the world’s first zero-emissions regional airliner. You will play a leading role in developing the embedded software controlling new technologies including hydrogen fuel cell systems and megawatt-scale electric motors for the first time in commercial aviation, resulting in a pioneering flight test program starting before the end of 2022. You will be working within a tight-knit and multidisciplinary team to rapidly iterate the design and testing of this cutting-edge hydrogen powertrain for aircraft.

About the Role

  • Formulate and execute embedded software development life cycle activities such as creating software planning documents and standards, creating high and low level requirements, software architecture design and coding.
  • Create software models for auto code generation, using state of the art modeling tools.
  • Write software code in C/C++ for low level embedded kernels and communication protocols.
  • Perform structural coverage analysis, stack/time/ memory analysis.
  • Participate in product development and architecture design review for embedded software projects
  • Be familiar with and support requirement based testing, software quality process, hardware-software integration, data and control coupling.

About Us

At Universal Hydrogen, our mission is to fuel carbon-free flight and reduce the climate impact of air travel. We are stitching together the end-to-end hydrogen value chain for aviation, both for hydrogen fuel and hydrogen-powered airplanes. We are building a transport and logistics network that moves hydrogen from production facilities to airports over the existing freight infrastructure, eliminating the need for costly new pipelines and storage facilities. Our system utilizes specialized capsules that safely store hydrogen during transit and act as modular fuel tanks that load directly onto aircraft. We are also developing powertrain conversion kits to retrofit existing airplanes and enable new airplanes to fly on hydrogen. Founded by former executives from Airbus, United Technologies, Google, and DARPA, and backed by investors such as Playground Global, Tencent, Toyota, GE, JetBlue, and Airbus, we are convinced that hydrogen is the best and only scalable solution to truly decarbonize aviation, and we want to bring it to market decades sooner—by 2025.

We strive for a workplace that is open, friendly, and fun, while valuing focus, urgency, camaraderie, and maverick behavior in accomplishing our mission. We recognize that people have a diverse set of preferences for work conditions and hours that optimize their overall productivity and wellness, and both our cloud-based IT setup and flexible work policy reflect this. However, because we are building physical products, most roles will require working at our facility at Hawthorne Airport in Los Angeles or at Toulouse-Blagnac Airport in Toulouse most of the time.

Our compensation and benefits package promotes transparency, equitability, and long-term employee well-being, while rewarding individual and team performance. This includes a significant variable pay component in the cash compensation, equity participation for all employees, a stipend for healthcare costs, and dog-friendly offices. As a young company, we are continually expanding our benefits, striving to provide our employees with the support they need to be their best both in and outside of the office. Additional benefits include 401(k) with a company match, unlimited paid time off, catered lunches, and private pilot (PPL) training—and we’re always open to feedback on what’s most important to you! 

We know that no two candidates are the same, and we want to give you the opportunity to present yourself in the best way possible. Don’t hesitate to let us know how we can support a great recruitment process for you—whether that includes off-hours interview scheduling, captioning/transcription services, or other accommodations. We value diversity in all its forms, and encourage people from all backgrounds to apply, especially if you share in our mission to decarbonize air travel.

Please note that for the health and safety of our employees, we require all employees to provide proof of up-to-date COVID-19 vaccinations as recommended by the CDC (or a valid exemption).
