Staff Software Engineer

Amperesand is building next-generation power infrastructure systems for Data Centers, EV charging platforms, and future energy applications. Our systems combine advanced power electronics, embedded controls, and scalable energy architectures to rethink how power is converted, controlled, and deployed.

At Amperesand, you will lead the design and development of a scalable, robust distributed test framework in Golang that automates test systems across our labs and manufacturing lines, accelerating prototype validation and ramping high-volume production. You'll own the technical direction of our test software, set engineering standards, and mentor the team. Your hardware background lets you design efficient, accurate test systems for our Solid State Transformer and integrate them with manufacturing systems.

Architect a highly scalable, modular test framework in Golang to test high-voltage power electronics, thermal systems, and more, spanning lab validation, regression testing, and production.

Drive end-to-end test software development from design through deployment and post-deployment improvements, building in ease of validation and maintenance.

Integrate test systems with MES and other databases to enable traceability and closed-loop feedback between test results and production.

Innovate test system design by collaborating with electrical, mechanical, firmware, and manufacturing teams, and provide feedback to improve product quality.

Lead and mentor the software team: establish development standards, foster a strong code review culture, and drive adoption across the team.

Participate hands-on in test hardware bring-up, system debugging, and optimization to meet accuracy, cycle time, and throughput targets.

Travel to facilities worldwide to collaborate with teams and deploy our solutions.

BS or MS in Computer or Electrical Engineering, or equivalent experience.

6+ years designing and building scalable software for distributed systems, with demonstrated technical leadership on complex projects.

Deep expertise in system-level languages (Golang, Rust, C, C++, etc.) with excellent software fundamentals: architectural design, algorithms, data structures, modularity, and maintainability.

Strong command of concurrency, asynchronous programming, and distributed systems to meet strict cycle-time requirements and maximize throughput.

Experience ingesting high-volume data for real-time decision-making, and with both relational and non-relational databases.

Strong hardware background: experience with electrical hardware, microcontrollers, and communication protocols (CAN, SPI, I2C, etc.), sufficient to design efficient, accurate test systems.

Experience working with Linux.

Proven ability to mentor engineers, build team depth, and drive adoption of engineering standards.

Engaged, proactive, and positive in owning challenging work and taking accountability for team success.

Employment Type: • Full-time Location: San Francisco/Sunnyvale / Reno Work Model: • Onsite Onsite Collaboration Rationale: Given the highly collaborative and cross-functional nature of hardware, embedded systems, and product development, in-person partnership across engineering and product teams is critical to enabling rapid execution, technical alignment, and successful development outcomes.

Work on next-generation power infrastructure systems • High ownership and visibility • Cross-functional collaboration • Opportunity to shape future products and infrastructure • Fast-moving startup environment
