About the role

We are looking for a hands-on Electrical Engineer to lead the development of high-reliability electronics for our interceptor prototypes and future VLEO satellites. You will own everything from board-level design to power systems, sensor integration, EMI/EMC, and flight hardware integration. Expect to work directly with founders, integrate components, run tests, and ship hardware that flies and intercepts targets.

If you’re excited by high-stakes engineering, rapid prototyping, and pushing physics boundaries, we are going to get along great!

What You’ll Do

Electrical Design & Prototyping

  • Design, simulate, and develop PCBs for sensing, actuation, power, and avionics.
  • Own schematic capture, layout, DFM, component selection, and vendor interaction.
  • Develop high-reliability power systems (DC–DC, battery systems, protection circuits, transient management).

Sensor and Actuator Solutions

  • Integrate IR cameras, Radar, IMUs, GNSS, rad-hard components, and electromechanical actuators.
  • Develop signal-conditioning circuits, sensor fusion interfaces, and low-latency sensing+actuation to enable the autopilot to control the vehicle.

Flight Hardware & Harsh-Environment Design

  • Perform thermal, vibration, and shock analysis for >100km altitude environments.
  • Support hardware qualification: TVAC, vibe, EMI/EMC, and high-G ground testing.

Embedded & System Integration

  • Collaborate closely with embedded software engineers on microcontroller architectures, drivers, and electrical-firmware interfaces.
  • Bring-up, debug, test, and iterate hardware in the lab using scopes, logic analyzers, DAQs, etc.

Execution & Ownership

  • Write requirements, test plans, and documentation.
  • Take hardware from concept → prototype → test → flight-ready.
  • Rapid debugging and converging on functional+performant solutions.

Required Qualifications

  • B.S. or M.S. in Electrical Engineering, Computer Engineering, or related field.
  • Strong experience with PCB design tools (KiCad, Altium, or similar).
  • Hands-on prototyping experience: soldering, rework, bring-up, rapid iteration.
  • Experience integrating sensors, mixed-signal electronics, or power systems.
  • Comfort with oscilloscopes, logic analyzers, protocol analyzers, and test equipment.
  • Strong fundamentals in circuit analysis, signal integrity, noise, grounding, and EMI/EMC.
  • Ability to own hardware end-to-end: design, build, test, debug, iterate.
  • US CITIZENSHIP REQUIRED

Nice to Haves

  • Experience with IR cameras, high-speed digital buses, or RF systems.
  • Background in aerospace, defense, robotics, autonomous systems, automotive, or satellites.
  • Knowledge of high-G design, radiation effects, or space-environment electronics.
  • Embedded firmware experience (C/C++, STM32/Teensy/PIC/ESP32, RTOS).
  • Familiarity with power systems, motor drives, or actuator control.
  • Experience with MIL-STD-461, DO-160, or NASA/ESA flight hardware standards.

About the interview

  • 15-30 min phone intro with CEO
  • 1 Hour phone deep dive with CTO
  • 1 Hour in person with CEO

About Wardstone

Wardstone is building the next generation of space-based missile defense. We design and deploy autonomous orbital interceptors capable of defeating hypersonic and ballistic threats, a capability the U.S. and its allies urgently need but that no one has yet delivered.

At Wardstone, you will build hardware that gets tested constantly and pushed to its limits, from US Air Force assisted ground experiments to supersonic ground launched platforms to future orbital prototypes. You’ll work on systems that combine advanced sensing, guidance, high-energy physics, and spaceflight in ways few organizations on Earth attempt.

We are a small, elite engineering team moving fast to solve problems of national importance. Every engineer has massive ownership, rapid iteration cycles, and a direct impact on the direction of the company and the defense of millions of people.

If you want to work at the intersection of space, autonomy, and national security, you should join Wardstone.
