Research Electrical Engineer
About The Position
Marathon Fusion is building the engineering technologies needed to scale fusion from breakeven experiments into real power plants. While much of the industry is focused on proving new fusion devices, our focus is on the practical systems that will make fusion deployable at climate-relevant scale. We develop core fuel cycle and plant-level technologies for stable isotope production, fuel cycle closure, and advanced blanket systems that enable both energy generation and high-value co-products. Founded in 2023, Marathon Fusion is building the components and systems that will help fusion become a practical, abundant, and reliable energy source for the 21st century. We are a startup environment characterized by a need for focus, adaptability and prioritization in a shifting landscape. Thriving in this environment requires excellent proactive communication across roles and backgrounds, the ability to build and maintain trust between team members, and the willingness to learn and develop new skills on the job. We place particularly high weight on each team member's ability to be self-directed. We are seeking an Electrical Engineer with hands-on experience in high-power and control systems. You’ll work closely with mechanical engineers, physicists, and technicians, to prototype, test, and deploy solutions in the pursuit of advancing the development of the fusion fuel cycle and stable isotope production. This role requires a blend of practical engineering skills and systems level thinking. You will play a pivotal role in integrating and supporting power systems, developing safe and robust control architectures, and standardizing data collection across experimental test stands.
Requirements
- B.S. or higher in Electrical Engineering or related field with more than 5 years of experience in a relevant industry
- Experience with high-power electrical systems, including power conversion, protection, and switching.
- Experience designing and working with PCBs using Altium Designer or equivalent.
- Proficiency in designing and maintaining data acquisition (DAQ) systems, including GUI design (e.g., LabVIEW, PLC programming, Python, etc.)
- Familiarity with industrial control systems, including PLCs, sensors, relays, and safety interlocks.
- Demonstrated experience collaborating with panel shops or technicians to bring designs into physical reality.
- Knowledge of safe design practices for high-voltage or high-energy environments.
- Strong mechanical intuition and comfort working around experimental systems.
Nice To Haves
- Prior experience in the fusion energy or related high-energy industries.
- Experience with pulsed power systems.
- Developing control logic using ladder logic programming.
- Designing or deploying SCADA systems for monitoring and control.
- Experience working in a highly ambiguous fast-paced startup or research environment.
Responsibilities
- Collaborate closely with mechanical engineers and technicians to rapidly prototype and test experimental systems
- Design, integrate, and support high-power and pulsed power systems with a focus on safety, reliability, and performance
- Develop, standardize, and maintain data acquisition systems across multiple test setups
- Define, implement, and document control system architectures, including hardware selection, wiring diagrams, and functional logic
- Coordinate with panel shops or internal technicians to layout, build, and validate custom control panels
- Contribute to the safe design and operation of high-voltage, high-current equipment
- Support testing, troubleshooting, and commissioning of control systems and power electronics
Benefits
- Medical, dental, and vision insurance
- Generous paid time off and sick leave
- 401(k) plan with 4% employer match
- Commuter benefits
