<div class="content-intro"><p><strong><span data-contrast="none">Company Overview  </span></strong><span data-ccp-props="{}"> </span></p> <p data-start="82" data-end="157">Amperesand is reinventing how the world powers its most critical systems.</p> <p style="text-align: left;" data-start="159" data-end="479">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.</p> <p data-start="481" data-end="858">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.</p> <p data-start="860" data-end="1072">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.</p> <p data-start="1074" data-end="1363">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.</p> <p data-start="1365" data-end="1533">Scalable in-house advanced manufacturing capability is our foundation for meeting timeline and quality expectation to serve infrastructure customers around the world.</p> <p data-start="1535" data-end="1720">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.</p> <p data-start="1722" data-end="1911">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.</p> <p data-start="1913" data-end="1968" data-is-last-node="" data-is-only-node="">Join us in building the power foundation of the future!</p></div><p><strong><span data-contrast="none"><span data-ccp-parastyle="heading 1">Role Summary</span></span></strong><span data-ccp-props="{"134245418":true,"134245529":true,"335559738":480,"335559739":0}"> </span></p> <p> <br><span data-contrast="auto">Amperesand is looking for a </span><strong><span data-contrast="auto">Senior Staff Thermo-Mechanical Design Engineer </span></strong><span data-contrast="auto">to play a key technical leadership role in developing its next-generation medium-voltage solid-state power conversion platform. This is a highly hands-on, end-to-end role where you’ll own the architecture of our complete thermal system—from architecture and concept selection, system sizing and modeling, CAD and detailed design, thermal CFD simulation, coolant and airflow routing, design for manufacturing and assembly, thermal system validation, and troubleshooting.  </span><span data-ccp-props="{}"> </span></p> <p><span data-contrast="auto">You’ll work closely with mechanical, electrical, manufacturing, quality, suppliers, and factory teams to design, develop, and build the best system for a novel application, solve problems that don’t have established answers, with the opportunity to own thermal design.  Thermal performance is key to the overall performance of our solid-state power converter and a key differentiator for Amperesand.  We are looking for someone with deep thermal system design expertise, system modeling, detailed design experience, and a track record of independently leading complex technical work and solving novel problems.  We are not looking for someone who simply executes to a defined specification. The role can be based in Reno, San Francisco, or the South Bay.</span><span data-ccp-props="{}"> </span></p> <p><strong><span data-contrast="none"><span data-ccp-parastyle="heading 1">What You’ll Do</span></span></strong><span data-ccp-props="{"134245418":true,"134245529":true,"335559738":480,"335559739":0}"> </span></p> <p><span data-ccp-props="{}"> </span></p> <ul> <li data-leveltext="" data-font="Symbol" data-listid="17" data-list-defn-props="{"335552541":1,"335559685":720,"335559991":360,"469769226":"Symbol","469769242":[8226],"469777803":"left","469777804":"","469777815":"hybridMultilevel"}" data-aria-posinset="1" data-aria-level="1"><span data-contrast="auto">Own the complete thermal system for Amperesand’s solid-state power conversion platform from architecture into mass-production.</span><span data-ccp-props="{}"> </span></li> </ul> <ul> <li data-leveltext="" data-font="Symbol" data-listid="17" data-list-defn-props="{"335552541":1,"335559685":720,"335559991":360,"469769226":"Symbol","469769242":[8226],"469777803":"left","469777804":"","469777815":"hybridMultilevel"}" data-aria-posinset="2" data-aria-level="1"><span data-contrast="auto">Select the architecture of our next-generation thermal system to meet and exceed product-level requirements.</span><span data-ccp-props="{}"> </span></li>
