About Us
We’re a combat-tested group of engineers, operators, and entrepreneurs who believe America’s edge depends on autonomous airpower that’s trusted and deployable today not in 2040. Backed by tier-one investors, we’ve secured the runway - financial, regulatory, and literal - to move at startup speed while tackling a national-security mission that matters. We’ve structured the company for radical ownership: no silos, no “systems integrator” overhead, just tightly knit mission-focused IPTs that live and breathe the hardware and code they ship.
If you thrive where hard-tech ambition meets national-security urgency, you’ll build faster here than anywhere else. Let’s get after it.
Culture That Ships
- Strong Core Values, Startup Execution. Integrity, Service Before Self, Excellence, Honor, Courage, Commitment—powered by a bias for action and a “figure it out” mindset.
- Self-Starters Only. You’ll have clear objectives, a blank sheet of paper, and the trust (plus capital) to move fast. Bureaucracy stays out of your way.
- One Team, No Tourists. Whether you’re tuning a control law at 2 a.m. or heat-treating a Ti-6Al-4V spar, everyone sweats the details. We celebrate wins together and own failures together.
What’s In It for You
- Mission With a Pulse. Every line of code, bracket, or test you deliver expands the toolbox of the warfighter on Day 1 of a conflict.
- Resources Without Red Tape. VC speed + DoD customer pull: access to test ranges, flight hours, and operator feedback while retaining startup agility.
- Career-Defining Upside. Significant equity, best-in-class benefits, and the chance to see your product deliver in months, not decades.
About the Role
We’re looking for an Avionics Architecture Lead Engineer to own the end-to-end avionics system design for our autonomous aircraft. You will define the architecture, manage key avionics subcontractors, and ensure the system meets FAA certification requirements.
This is a hands-on technical leadership role for a self-starter who can zoom from high-level architecture down into ICD details, test plans, and flight-test findings.
What You’ll Do
- Own the avionics architecture.
- Define the end-to-end avionics system, including mission computers, navigation, communications, surveillance, and payload interfaces.
Select network topologies (ARINC 664/AFDX, TSN Ethernet, ARINC 429, CAN, etc.) and define redundancy, partitioning, and data flows.
- Lead supplier & subcontractor integration.
- Serve as primary technical point of contact for avionics vendors and integrators.
- Drive SOWs, technical requirements, ICDs, and acceptance criteria.
- Review vendor designs, safety artifacts, and test results; hold them accountable to cost/schedule/technical performance.
- Ensure FAA airworthiness compliance.
- Architect the system in accordance with ARP 4754A/4761, DO-178C, DO-254, DO-160, and applicable Part 23/25 guidance.
- Support System Safety in the development and maintenance system-level requirements, safety analyses (FHA, PSSA, SSA), and certification plans.
- Drive verification & validation.
- Develop system-level test plans, HIL/LRU integration plans, and test objectives.
- Work with test and flight teams to triage anomalies, root-cause issues, and feed fixes back into the architecture.
- Collaborate across the stack.
- Partner with Autonomy, GNC, Flight Controls, and Cyber teams to ensure avionics supports robust, resilient autonomous operations.
- Communicate clearly with leadership on risk, mitigations, and tradeoffs.
What You Bring
- B.S. in Electrical Engineering, Computer Engineering, Aerospace Engineering, or related field.
- 5+ years of relevant experience in avionics systems design and integration on certificated aircraft.
- Proven experience with FAA certification efforts, including hands-on work with some combination of:
- ARP 4754A / ARP 4761
- DO-178C (software)
- DO-254 (hardware)
- DO-160 environmental testing
- Part 23 or Part 25 certification projects
- Strong systems engineering fundamentals: requirements development, ICDs, safety analysis, verification planning.
- Demonstrated experience integrating avionics LRUs, networks, and sensors in a lab or flight-test environment.
- Track record of leading and managing subcontractors or vendors—able to push back technically and keep them aligned to mission and schedule.
- Excellent communication skills; comfortable presenting architecture and certification status to both engineers and non-technical stakeholders.
- U.S. Person, eligible to obtain a DoD Secret clearance.
Bonus Points
- Experience with defense-focused avionics or mission systems (Link-16, SATCOM, tactical radios, radar, EO/IR, etc.).
- Prior work on UAS, optionally-piloted, or highly autonomous aircraft.
- Familiarity with GRA, MOSA, or SOSA standards and modular open-systems architectures.
- MBSE experience (SysML, Cameo/MagicDraw) linking avionics design to the broader digital thread.
- FAA DER and/or E-UM Ticket in applicable Airworthiness Standards
