Electricity demand is skyrocketing, driven by AI factories, electric vehicles, and modern industrial growth. Energy supply is shifting to incorporate a more diverse mix of resources - including solar, gas, and batteries - at a massive scale.\nAnd yet the power infrastructure behind our latest mega-projects hasn’t meaningfully changed in nearly 100 years. Supply chains for today’s infrastructure equipment can’t match the pace and sophistication of critical energy projects. Amperesand is building hardware and software that rewrites this broken power infrastructure playbook to support a new era of energy abundance.\nWe’ve built a new class of intelligent, software-defined power infrastructure products leveraging a decade of advanced medium voltage Solid State Transformer research that’s now ready for commercial deployment.\nOur products and solutions go far beyond the capabilities of traditional electrical equipment. We make power systems that are faster to deploy, dramatically smaller and more efficient, and capable of supporting modern, dynamic energy needs for tomorrow’s most demanding energy consumers.\nScalable in-house advanced manufacturing capability is our foundation for meeting timeline and quality expectation to serve infrastructure customers around the world.\nAmperesand is led by breakthrough energy hardware development veterans and funded by top tier investors who share our vision of building a category-defining energy technology company.\nWith hubs in San Francisco, Reno, and Singapore, our global team is laser focused on building foundational technology to solve the most pressing problems in power infrastructure at scale.\nJoin us in building the power foundation of the future!\nRole Summary\nIn this role, you will lead the control architecture and system behavior of advanced AC-DC and DC-DC power conversion platforms across low- and medium-voltage applications. You will define and drive control strategies for complex converter topologies, including multilevel and resonant systems. As a Staff engineer, you will own system-level control decisions, set technical direction across programs, and ensure performance targets are achieved from concept through production. You will work across modeling, digital control development, embedded implementation, hardware integration, and validation to deliver robust, scalable, high-performance power conversion solutions. You will also mentor engineers and raise the technical standard of the control organization\nResponsibilities:\nOwn control architecture for advanced power conversion systems across AC-DC and DC-DC platforms.\n\nOwn system-level dynamic performance (stability, bandwidth, transient response, robustness, efficiency) from concept through production.\n\nDrive control strategy across interacting power stages and ensure stable operation under all operating conditions.\n\nDefine digital control execution requirements and ensure real-time implementation meets system performance targets.\n\nLead system-level stability analysis and performance closure under aggressive development timelines.\n\nEstablish validation methodology and acceptance criteria, including frequency response, transient testing, and fault handling robustness.\n\nLead complex root-cause investigations across hardware, firmware, sensing, and protection domains.\n\nDrive control-related risk assessment (DFMEA) and mitigation planning across development programs.\n\nEnsure control solutions scale across product variants and future platforms.\n\nInfluence system-level trade-offs across topology, sensing, control strategy, performance, cost, and power density.\n\nElevate control engineering standards through rigorous design reviews, modeling discipline, and mentorship.\n\nQualifications:\nDegree in Electrical Engineering or equivalent industry experience with strong specialization in power electronics and control systems.\n\n5+ years of experience designing and deploying digital control for power converters in commercial or industrial applications.\n\nDemonstrated ownership of control architecture or system-level dynamic performance in complex power conversion systems (e.g., multi-stage, high-power, grid-connected, or modular platforms).\n\nStrong expertise in advanced converter control, including resonant, multilevel, or other high-performance topologies across isolated and non-isolated systems.\n\nExperience with solid-state transformer (SST) architectures or tightly integrated multi-stage AC-DC/DC-DC systems is strongly preferred.\n\nDeep command of control theory, including multi-loop stability analysis, loop interaction mitigation, nonlinear system behavior, and dynamic modeling.\n\nProven experience implementing and guiding high-performance real-time digital control on embedded platforms (DSP/MCU/SoC).\n\nStrong proficiency in embedded C and ability to review and influence real-time control implementation decisions.\n\nExtensive hands-on laboratory experience debugging high-power systems and leading system-level validation and performance closure.\n\nDemonstrated ability to independently resolve complex, cross-domain technical challenges and drive cross-functional trade-off decisions.\n\nBonus Qualifications: \nExposure to medium-voltage power electronics systems.\n\nExperience with multilevel or modular converter architectures.\n\nExperience with bidirectional power flow control.\n\nExperience supporting products from R&D through production release.\n\nExperience contributing to patents or novel control techniques.\n\nPlease note: This role requires working on-site 5 days a week. We do not offer hybrid or remote options. \nSalary: $175,000-$310,000/annual DOE and location\nPlease note: This role requires working on-site 5 days a week.
