Sobre este puesto de Senior Electronics Design Engineer en Amperesand
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 Senior Electronics Design Engineer, you will design and develop the low-voltage and mixed-signal hardware that controls, senses, and protects our Solid-State Transformer (SST) subsystems. You'll own boards end-to-end - from schematic through bring-up and release to production and contribute to architectural decisions. This is a hands-on role for an engineer who wants depth in mixed-signal design for high-reliability power conversion products.
Responsibilities
- Design low-voltage and mixed-signal circuits for SST products, balancing performance, reliability, safety, cost, and manufacturability.
- Select microcontrollers and key ICs; engage with silicon vendors to evaluate fit and review errata.
- Design and validate control, sensing, and protection circuitry - including 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.
- Build redundancy and fault tolerance into board designs to meet single-fault-tolerant and product-lifetime requirements; contribute to DFMEA and derating reviews.
- Implement industrial and high-bandwidth communication interfaces (e.g., Gigabit Ethernet, CAN, Modbus) with attention to signal integrity.
- Partner with a dedicated PCB layout engineer. Define stackup, impedance, isolation, and routing constraints, review iterations, and execute layout directly when needed.
- Own full lifecycle development of PCBAs: 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.
- 5+ years designing low-voltage and mixed-signal hardware, with at least some experience in high-reliability or high-voltage systems.
- Experience taking boards from schematic through bring-up and production, including MCU selection and protection circuitry.
- Solid analog and mixed-signal design skills, with knowledge of component selection and derating for harsh environments.
- Experience designing isolated interface circuits between voltage domains.
- Hands-on experience with communication interfaces such as Ethernet, CAN/CAN-FD, or Modbus.
- Proficiency with PCB CAD and simulation tools (preferably Altium Designer, SPICE, and/or PLECS).
- Hands-on PCB layout experience sufficient to specify constraints, review layout, and execute layout directly 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.
- Exposure to functional safety (IEC 61508, ISO 13849) or HV design and certification standards (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.
While this role is listed for the location above, we may consider candidates in other locations on a case-by-case basis.
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.
Why Join Amperesand
- 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
