Senior Mechanical Equipment Design Engineer

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!

About Amperesand

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.

About the Role

We are seeking an accomplished and innovative Sr. Equipment Mechanical Design Engineer to join our team and drive the development of custom equipment for manufacturing power electronics products. In this role, you will be responsible for architecting, designing, and validating high-performance mechanical systems and automation equipment, ensuring robust operation. You will collaborate closely with product design, manufacturing, controls engineering and test engineering teams to develop scalable and reliable equipment solutions that meet performance, cost, and throughput targets.

This position presents an opportunity to influence equipment design from its inception, enabling early integration of design for manufacturability (DFM), design for excellence (DFX), and design for assembly (DFA) principles. As a critical interface between product development and industrialization, you will help translate cutting-edge hardware concepts into production-ready systems that meet the demands of high-volume, high-reliability manufacturing.

What You’ll Do

Conceptualize, design, and develop custom automation equipment, robotic cells, material handling systems, tooling, and fixtures

Utilize CAD software (SolidWorks, CATIA, AutoCAD, etc.) to create detailed mechanical designs

Contribute to product DFA to improve overall manufacturing cost and quality

Develop mechanical systems incorporating servo motors, actuators, pneumatics, hydraulics, and robotics

Work with controls and electrical engineers to integrate PLC, HMI, sensors, and vision systems.

Optimize design of equipment for repeatability, precision, availability, and cycle time

Lead design reviews, and risk assessments

Identify opportunities for equipment optimization, efficiency improvements, and cost reduction

Work with EH&S teams to ensure regulatory compliance and risk mitigation.

What You’ll Bring

BS or MS in Mechanical Engineering, Manufacturing Engineering, or a related field

3+ years of hands-on experience in Mechanical design

Hands-on experience in fixture, tooling and equipment design

Experience with servo motors, pneumatics, linear actuators

Knowledge of sensors

Experience in CAD software (3DEXPERIENCE (3DX), CATIA, NX, SolidWorks, Creo etc.)

Experience with DFM/DFA (Design for Manufacturing/Assembly) methodologies

Ability to mentor junior engineers

Background in process development, optimization, and troubleshooting in a high-volume production environment

Good understanding of GD&T and its impact on manufacturability

Willingness and ability to travel up to 15% including internationally

Excellent written and verbal communications in English

Nice to Have

Experience in structural, thermal, and vibration analysis using tools like Ansys Mechanical, Fluent, and Maxwell

Experience with precision machining, welding, sheet metal fabrication, injection molding, and dispensing processes

2+years of experience in manufacturing engineering is desired

Familiarity with electronics packaging and PCB interface considerations

Experience with medium- to high-voltage systems and insulation coordination (creepage, clearance, potting, sealing)

Basic knowledge of digital and analog electronics

Power Electronics Assembly experience is highly valued from energy, automotive, aerospace, semiconductor, or consumer electronics manufacturing
