Software 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! Role Summary At Amperesand, you will develop highly efficient and modular software to automate test systems for internal labs and manufacturing lines. Responsibilities: Design a highly scalable software framework in Golang to test high-voltage power electronics, thermal systems, and more. Adopt design for lab validation, regression test setup, and production environment. Drive end-to-end test software development from design through deployment and post-deployment improvements. Participate in and lead code reviews to maintain code quality and adhere to coding standards. Innovate software and system design to meet accuracy, cycle time, and other performance factors. Collaborate closely with hardware design and firmware teams to understand the product and its functionalities. Investigate root causes of failures and drive product improvements. Participate hands-on during test hardware bring-up, system debugging, and help with software optimization. Incorporate design techniques to achieve ease of validation and maintenance. Challenge ideas and decisions with reasoning from first principles. Travel to different facilities worldwide to collaborate with teams and deploy our solutions. Qualifications : BS or MS in Electrical or Computer Engineering. 1+ years of professional experience in developing software for distributed systems. Basic understanding of electrical theory. Experience with testing and measurement hardware platforms. Expertise using system-level languages (such as Golang, Rust, C, C++, etc.) to automate systems. Ability to write efficient code under resource constraints (memory, CPU). Experience with version control systems like Git. Experience with microcontrollers and communication protocols (CAN, SPI, I2C, etc.). Be engaged, proactive, and positive when taking on challenging tasks, owning assignments, and taking accountability for personal and overall team success.
