We are pioneering modular motion technologies to power the next generation of innovation for Industrial, Aerospace and Defense. If you're excited about disrupting legacy industries and building safety-critical systems that fly, let's chat!

We are at the forefront of innovation, crafting exclusive motion control components that propel the aerospace and defense sectors into the future.

A couple other things:

• We offer a lot of autonomy
• We like to run lean for impact
• We have great benefits
• We are well funded, and already generating revenue
• We just moved into a new large hangar facility in Hawthorne, CA

We are looking for a Senior Systems Engineer with deep expertise in safety and reliability to own safety and reliability deliverables across the product lifecycle — from requirements and architecture through analysis, test, and certification. You will work directly with our systems engineering lead, DER, and cross-functional leads across hardware, software, and mechanical engineering on a fast-moving FAA Part 25 / EASA CS-25 certification program.

• Hazard Analysis & Assessment: Own FHA, PSSA, and SSA activities end-to-end. Produce certification-quality deliverables that satisfy SAE ARP4754B and SAE ARP4761A guidelines.
• Fault Analysis: Lead FTA and FMEA/FMES (Failure Modes and Effects Summary) development across system, subsystem, and component levels. Maintain traceability from hazard to design mitigation to verification evidence.
• Requirements Allocation: Define and allocate safety requirements to hardware, software, and mechanical subsystems. Track closure through test and analysis.
• Certification Interface: Serve as the safety engineering point of contact for the FAA DER and airframe customer technical teams. Support development of safety plans, compliance checklists, and design assurance documentation.

• Reliability Modeling: Develop and maintain reliability models and predictions using MIL-HDBK-217, FIDES, or equivalent methods. Own MTBF analysis and reliability requirement allocation to subsystems.
• FMEA/FMES: Drive reliability-focused FMEA activities that feed both design decisions and safety analysis inputs.

• Design Reviews: Participate in PDR and CDR as the safety and reliability subject matter expert. Identify and drive resolution of safety-relevant design risks.
• Software & Hardware Interface: Support DO-178C and DO-254 planning activities as they interface with system-level safety requirements.

• Education: Bachelor's degree in Systems Engineering, Aerospace, Electrical, or Mechanical Engineering. Advanced degree a plus.
• Experience: 5+ years of systems engineering experience, with at least 3 years focused on safety and/or reliability analysis. Hands-on ownership of deliverables — not just familiarity.
• Safety Frameworks: Demonstrated working knowledge of SAE ARP4754B and SAE ARP4761A, or equivalent frameworks (IEC 61508, MIL-STD-882, ISO 26262 considered). Must have owned FHA, FTA, and FMEA/FMES deliverables through a formal review.
• Reliability Methods: Proficiency in MTBF analysis and reliability prediction. Ability to build and maintain reliability models independently.
• Communication: Strong written communication; able to produce certification-quality documentation that holds up to DER and airframe customer scrutiny.

• Experience with FAA Part 25 or Part 23 certification programs.
• Familiarity with DO-160G, DO-178C, and/or DO-254 as they intersect with system safety.
• Background in adjacent industries is welcome — defense, medical devices, and automotive functional safety (ISO 26262) develop the same analytical rigor we need.
• Prior experience at a small or scaling aerospace company.

We are not just building components. We are reshaping the future of the Aerospace and Defense component industry, which is a $300B+ market! Come join us and help build next generation systems that will make a massive impact at global scale.

• Salary Range: $160,000-$175,000, plus equity and benefits at a well-funded, fast-moving startup
• We offer competitive compensation + equity 
• Exceptional healthcare benefits, Medical is 100% covered by the company
• Flexible PTO
• 401K
• More to come!
