Salary: USD 150,000 - 200,000 / annual
Amperesand is building next-generation power infrastructure systems to support the energy transition. The company develops intelligent, software-defined power infrastructure products based on advanced medium-voltage solid-state transformer (SST) technology, designed to be faster to deploy, more efficient, and capable of supporting modern dynamic energy needs for AI factories, electric vehicles, and industrial growth.
As Senior Power Electronics Control Engineer, you will own the control and system behavior of advanced power converters across AC-DC and DC-DC topologies used in low-voltage and medium-voltage power conversion systems. Your focus will be on multilevel power converter architectures and resonant power conversions in solid-state transformers. You will work hands-on across control design, modeling, analysis, laboratory debugging, and validation, collaborating closely with hardware, firmware, and system engineers to bring robust power electronics solutions from concept through deployment.
Key Responsibilities:
- Design and implement digital control algorithms for advanced AC-DC and DC-DC power converters across low- and medium-voltage applications
- Develop small-signal and large-signal models to support stability analysis, loop compensation, and transient optimization
- Support development of control strategies for advanced power conversion stages, including multilevel or resonant topologies and AC-DC/DC-DC stage interactions
- Implement real-time control algorithms on DSP/MCU/SoC platforms
- Lead hands-on debugging and root-cause analysis across simulation, firmware integration, hardware bring-up, and lab testing
- Collaborate with hardware and firmware teams to optimize sensing, protection, and control-loop performance
- Support validation activities including loop stability measurement, transient response testing, and fault handling verification
- Own complex control subsystems and contribute to system-level design under technical leadership
The role requires on-site presence 5 days per week at one of three locations (Reno, San Francisco, or Sunnyvale). The company emphasizes cross-functional collaboration and rapid execution in a fast-moving startup environment.
Requirements:
- Technical degree or equivalent industry experience in Electrical Engineering or closely related field, with strong focus on power electronics and control systems
- 3+ years of experience designing and deploying digital control for power converters, with demonstrated ability to own and execute complex technical tasks
- Strong understanding of resonant power conversion principles and their control implications across isolated and non-isolated power converter architectures
- Solid foundation in control theory, including loop compensation, stability margins, frequency-domain and time-domain analysis, and nonlinear system behavior
- Proven experience implementing real-time control algorithms on embedded platforms
- Hands-on laboratory experience debugging power converters
- Ability to translate theoretical control concepts into practical, robust implementations
- Strong problem-solving and analytical skills, with ability to work through technically ambiguous challenges
- Familiarity with modeling and simulation tools such as MATLAB/Simulink and PLECS
- Proficiency in embedded C for real-time control implementation and debugging
Bonus Qualifications:
- Exposure to medium-voltage power electronics systems
- Exposure to bidirectional power conversion and power flow control
- Experience supporting products from R&D through validation and deployment
