About the role

Company Overview Amperesand is reinventing how the world powers its most critical systems.
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.

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
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
Architect redundancy and fault tolerance into the board to meet single-fault-tolerant and product-lifetime requirements, lead DFMEA and derating reviews
Maintain documentation of requirements, design decisions, and release notes for traceability and compliance
Amperesand is building hardware and software that rewrites this broken power infrastructure playbook to support a new era of energy abundance.

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
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
Strong board bring-up, debugging, and lab testing skills, with working knowledge of EMI/EMC best practices
Strong analog and mixed-signal design skills with deep knowledge of component selection and derating for harsh environments
Hands-on PCB layout experience sufficient to specify constraints, review layout critically, and execute layout independently when needed
Excellent written and verbal communication in English
Willingness to travel up to 10%, including internationally

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

We are facing a once-in-a-generation opportunity for infrastructure disruption.
Scalable in-house advanced manufacturing capability is our foundation for meeting timeline and quality expectation to serve infrastructure customers around the world.
