Job Description
Company Overview
Amperesand is reinventing how the world powers its most critical systems.
We are facing a once-in-a-generation opportunity for infrastructure disruption. 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.
And 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.
We’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.
Our 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.
Scalable in-house advanced manufacturing capability is our foundation for meeting timeline and quality expectation to serve infrastructure customers around the world.
Amperesand 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.
With 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.
Join us in building the power foundation of the future!
Role Summary
As a Staff Electronics Design Engineer, you will architect and own the low-voltage and mixed-signal hardware that controls, senses, and protects our Solid-State Transformer (SST) subsystems. You'll make the foundational design decisions - from microcontroller selection to isolation architecture to redundancy strategy that determine whether our products meet their safety, reliability, and performance targets. This is a hands-on technical leadership role for an engineer who wants to own boards end-to-end, from concept through production
Responsibilities
- Architect low-voltage and mixed-signal subsystems for SST products, leading trade-offs across performance, reliability, safety, cost, and manufacturability
- Select microcontrollers and key ICs, partner with silicon vendors to evaluate fit, review errata, and influence part selection
- Design and validate control, sensing, and protection circuitry including high-accuracy analog measurement chains, digital I/O, and fault detection
- Design isolated interface circuits like signal isolators, isolated DC-DC, and fiber optics between different voltage domains
- Architect redundancy and fault tolerance into the board to meet single-fault-tolerant and product-lifetime requirements, lead DFMEA and derating reviews
- Implement high-bandwidth and industrial communication interfaces such as Gigabit Ethernet, CAN, and Modbus with attention to signal integrity
- Drive PCB layout in partnership with a dedicated layout engineer, define stackup, impedance, isolation, and routing constraints, review iterations, and execute layout directly when needed
- Own full lifecycle development of PCBAs including specifications, schematics, BOM, prototyping, bring-up, EMI/EMC compliance, and release to production
- Collaborate with firmware engineers on interface and timing definition, and with mechanical engineers on connector placement, thermal, and enclosure integration
- Maintain documentation of requirements, design decisions, and release notes for traceability and compliance
Qualifications
- BS or MS in Electrical Engineering, Computer Engineering, or equivalent industry experience
- 8+ years designing low-voltage and mixed-signal hardware for high-reliability or high-voltage systems, with demonstrated technical leadership across multiple programs
- Proven experience architecting boards from a blank sheet, including MCU selection, partitioning of control, sensing, and protection functions
- Strong analog and mixed-signal design skills with deep knowledge of component selection and derating for harsh environments
- Experience designing isolated interface circuits within reinforced isolation requirements
- Hands-on experience with communication interfaces such as Ethernet, CAN, and Modbus, including signal integrity for higher-speed links
- Proficiency with PCB CAD and simulation tools, preferably Altium Designer, SPICE, or PLECS
- Hands-on PCB layout experience sufficient to specify constraints, review layout critically, and execute layout independently when needed
- Strong board bring-up, debugging, and lab testing skills, with working knowledge of EMI/EMC best practices
- Excellent written and verbal communication in English
- Willingness to travel up to 10%, including internationally
Bonus Qualifications
- Shipped a PCBA in a high-volume product from prototype through sustained production
- Experience with functional safety such as IEC 61508, ISO 13849, or HV design and certification standards such as IEC 61800, UL 508C, IEC 62477
- Experience with high-reliability design for industrial, grid, or similar harsh-environment applications
Please note: This role requires working on-site 5 days a week. We do not offer hybrid or remote options.
