The Company

We are a startup based in the SOMA neighbourhood of San Francisco. We are a small, diverse team of creative thinkers. We value open communication, teamwork, and a make-it-happen attitude – no job is too big or too small. We strive to make a change by imagining what the future could be and building a product to complete that vision. We are looking to grow our team with talented people who are on the same mission to shape the future of energy.

We embrace diversity and equal opportunity in a serious way. We are committed to building a team that represents a variety of backgrounds, perspectives, and skills. The more inclusive we are, the better our work will be.



The Role

We aim to establish our panel as the centre of home energy and the backbone of the renewable distributed grid. To accomplish this, we will have to integrate with everything — or at least with every solar inverter, every storage battery, and every high-power smart appliance we can get our hands-on.

Designing and sustaining this broad and high-quality portfolio of technical integrations is the core mission of our Systems team. Our team drives systems architecture does systems integration, root causes problems, and builds internal infrastructure to keep our energy platform running smoothly and reliably.

As our lead systems integration engineer, your responsibility will be to own the integration between the panel and our growing list of technology partners. You will become our in-house expert on all aspects of the devices with which we integrate (e.g. power electronics, firmware, communications) and how our panel coordinates with them. You’ll be involved through the entire integration process, from initial design to lab testing and finally to remote monitoring in the field.




  • Develop a deep understanding of the inverters, energy storage systems, EV chargers, and appliances we’re integrating with: read their manuals cover to cover, install and operate them in the lab
  • Work with the firmware and software teams to design integrations (write specs, draw state machines)
  • Take point on lab testing: verify that your integration designs work; try to break things; characterize the integrated system (e.g. response time)
  • Coordinate with engineering teams from other companies: write integration proposals, serve as technical point of contact
  • Use fleet data to monitor device health in the field and solve problems
  • Reproduce and root-cause issues from the field; work with the team to develop and test fixes




Required Qualifications

  • Bachelor’s degree in electrical engineering, computer science, or related field
  • 5+ years’ professional hands-on experience with energy storage, inverter, EVSE, or similar hardware products (testing, firmware/hardware development, or systems integration)
  • First-rate understanding of electromagnetism, power electronics, and electrical engineering fundamentals; comfort reading PCBA schematics
  • Comfort using and reasoning about all manner of communications protocols (REST, CAN, Modbus, etc)
  • Extensive experience using oscilloscopes and other electrical instrumentation (logic analyzer, power analyzer, etc)
  • Comfort working with embedded systems — reading source code, reasoning about state machines, etc.
  • Solid hands-on electrical skills (wiring, soldering, etc.)
  • Comfort working with SQL and data visualization tools
  • Strong communication and interpersonal skills
  • Ability to understand and explain complex problems simply and effectively
  • A hacker’s instinct for making things work


Bonus Qualifications

  • Experience working with field data and doing remote troubleshooting/diagnostics
  • Experience programming in Python, Javascript, other scripting languages
  • Numerical programming experience (PANDAS, R, MATLAB)
  • Experience writing firmware / low-level languages (C, Rust) and using FreeRTOS or similar embedded operating systems




Working at our company, you can expect:

  • Competitive compensation at a well-funded, venture-backed company
  • Comprehensive benefits including a choice of medical plans; dental, vision, life and disability insurance
  • A sunny, airy office located close to BART and Caltrain public transit
  • Regular team lunches, brown bag learning opportunities, board games nights, and other opportunities to connect with teammates – in-person and now virtually
  • Equity grants at a quickly-growing startup
  • Flexible hours and vacation time – we simultaneously work hard and make space for the important stuff
  • To be a part of a team and culture that is hard-working has a good sense of humour, values collaboration, and is just a little bit nerdy
