# Software Engineer, Avionics at Furientis

- **Company:** Furientis
- **Location:** Los Angeles, CA
- **Work type:** onsite
- **Posted:** 2026-05-13
- **Last confirmed live:** 2026-09-10
- **Apply:** https://jobs.lever.co/furientis/35becc9f-0026-447f-8608-ba88c797ca0d

## Job description

America is critically deficient in production of defensive munitions- we currently produce shipborne interceptors in the few hundreds per year while our adversaries are producing offensive threats in the tens of thousands per year. Furientis was started to help solve this problem- introducing a new class of cost-effective, high production rate, interceptor missiles. We're seeking motivated individuals who internalize this problem and are eager to apply their past experience in similar industries (aerospace, defense, automotive/racing, robotics) and out of the box thinking to solve this problem for the US and its allies.

## About the Team

The Avionics Team owns the electronics on the vehicle: flight computer, compute boards, power conversion, sensor interfaces, wiring, and the embedded firmware that ties them together. The same engineers design the boards, write the firmware, and bring them up at the bench. No handoff layer between hardware and software.

Avionics sits on the critical path for every flight test, so the team's velocity sets the program's pace.

## About the Role

We are seeking an exceptional avionics software engineer to develop embedded systems and flight-critical software architectures for advanced aerospace platforms.

You will work across hardware, firmware, and real-time software systems while collaborating directly with electrical, controls, and mechanical engineers. You will own mission-critical avionics software that directly interfaces with flight hardware and operational systems, not isolated subsystems or legacy code.

This role is ideal for engineers who want broad technical ownership, rapid iteration cycles, and the opportunity to build systems that move from concept to flight quickly.

## What You'll Do

- Develop embedded avionics software in C/C++ and Rust.
- Design real-time software architectures for flight systems.
- Interface directly with avionics hardware, sensors, and communication systems.
- Develop software for power systems, telemetry, control systems, and onboard computing.
- Write the embedded servo firmware for the fin actuators: current loop, position loop, commutation, command interface, and fault handling. Implement to the Control Actuation Engineer's control law spec; tune with them on the bench.
- Support hardware bring-up, integration testing, and flight operations.
- Build robust testing and simulation frameworks.
- Participate in system-level architecture and safety reviews.
- Optimize performance, reliability, and fault tolerance of embedded systems.
- Collaborate closely with cross-functional engineering teams.

## Skills We're Hiring For

- BS/MS in Computer Engineering, Electrical Engineering, Aerospace Engineering, Computer Science, or related field.
- 5+ years of embedded software development experience.
- Strong proficiency in C/C++.
- Experience with real-time systems and embedded Linux or RTOS environments.
- Experience debugging hardware/software interactions.
- Familiarity with communication protocols such as CAN, SPI, I2C, UART, and Ethernet.
- Strong systems-level thinking and troubleshooting ability.
- Motor-control firmware experience: current and position loops, FOC or trapezoidal commutation, sensored or sensorless schemes, and real-time scheduling on a motor-control MCU.
- Excellent communication and teamwork skills.

Bonus Points For

- Experience with aerospace, automotive, robotics, or autonomous systems.
- Rust experience.
- Experience with DO-178 or safety-critical software processes.
- FPGA or low-level hardware interface experience.
- Experience with telemetry, flight controls, or navigation systems.
- Familiarity with Python tooling and automated testing.
- Experience supporting hardware integration and flight testing.

Eligibility & Logistics Location: On-site at our Los Angeles, CA HQ; remote work is not available. Monthly weekend travel for test events and supplier engagements. Clearance: A clearance is not required for this position. Must be a U.S. Person. Equal Opportunity & Export Compliance Furientis is an equal-opportunity employer. To comply with U.S. export control laws, employment is contingent on eligibility to access export-controlled information.

## About Furientis

## Company Overview
- **One-liner**: Furientis is a defense technology startup building low-cost, production-scalable interceptor missile systems for the U.S. military.
- **Entity Type**: Private (Pre-seed)
- **Headquarters**: El Segundo, California, USA (operates out of a facility in Playa Vista, Los Angeles)
- **Founded**: 2025
- **Founders**: Brody Franzen (CEO) and Aris Simsarian

## Core Business
- **Primary industry**: Aerospace & Defense / Defense Technology
- **Target customers**: U.S. military and defense organizations, particularly naval and ship-based interceptor procurement buyers
- **Mission or purpose statement**: "We believe the future of warfare is dictated by production capacity, and our current system of manufacturing critical defensive munitions cannot meet demand." The company aims to build cost-effective defensive munitions at scale.

## Products & Services
- **F 1.0 Interceptor Missile System**: A low-cost interceptor missile architected for an annual production volume of 1,000 units per factory. Designed to counter low-cost threats (drones, cruise missiles) that are expensive to stop with legacy systems. Uses automotive-style materials and assembly processes, commercial off-the-shelf components, and in-house solid rocket motors to achieve a cost of ~$250,000 per missile versus the $1–$5 million normally spent per interceptor.

## Market Standing
- **Valuation/Market Cap**: Not disclosed (Private, early-stage)
- **Key Metric**: $5M total funding raised (Pre-Seed round, announced May 2026)
- **Notable Investors/Partners**: Silent Ventures (lead), Bessemer Venture Partners, Multiball Capital, SV Angel, Humba Ventures, BVVC, Liquid 2 Ventures, MVP Ventures, Channel 39 Ventures, Vanderbilt University, Gaingels. Angel investors include founders of Anduril, Armada, and Erebor.
- **Growth Signals**: Emerging from stealth with $5M pre-seed; completed six flight tests and ten static-fire tests within its first six months; named a finalist in the Office of Naval Research Tactical Missile Innovation Challenge; actively hiring with 4+ open roles; projected "significant demonstrations" later in 2026.

## Competitive Advantages
- **Design for manufacturing from day one**: Unlike legacy primes that spend a year on modeling before building hardware, Furientis runs four-week design cycles with monthly flight tests—a "build fast, test often" approach.
- **In-house solid rocket motor production**: Most primes outsource this critical component, creating supply chain bottlenecks. Furientis makes its own, giving it control over the most constrained piece of the supply chain.
- **Cost advantage**: Target price is ~$250,000 per missile vs. $1M–$5M for incumbent systems from primes like Lockheed Martin, enabled by automotive-style materials, off-the-shelf components, and simplified assembly.
- **Production scalability**: Designed from scratch for a throughput of 1,000 units per year per factory, addressing the core national security bottleneck of ammunition production capacity.

## Strategic Focus
- **Scale production**: Move from prototype flight testing to initial production tooling and build-out of a 9,000-square-foot Los Angeles factory.
- **Team expansion**: Actively hiring elite engineers across opto-mechanical, perception hardware, and finance roles to accelerate development.
- **Demonstrate to the Navy**: Use ongoing flight tests and the ONR challenge to secure a production contract with the U.S. Navy.
- **Prove the thesis**: Continue monthly flight tests to validate the cost and performance of its interceptor system.

## Why Work Here
- **High-impact mission**: Work directly on solving a critical U.S. national security shortage—the ability to produce defensive munitions at the volumes needed to counter modern threats.
- **Fast-paced engineering culture**: Four-week design cycles, monthly flight tests, and a "build and break things" mentality that contrasts with slow, traditional defense primes.
- **Elite team and mentorship**: Leadership includes veterans of Virgin Galactic, Virgin Orbit, and Castelion (a hypersonics startup that raised $350M). Advisors/investors include founders of Anduril and Armada—among the most successful modern defense startups.
- **On-site in Los Angeles**: Roles are on-site in the Playa Vista / El Segundo area. The office is notably located in Lenny Kravitz’s former studio.
- **Early-stage equity**: Joining at pre-seed stage ($5M raised) provides significant ownership potential for early engineers alongside a small, tight-knit team (11-50 employees).
- **Active hiring**: As of mid-2026, open roles include Senior Opto-Mechanical Engineer, Perception Hardware Integration Engineer, and Finance Manager.
