Our Mission

SPAN develops products that accelerate the rapid adoption of renewable energy in the home. The flagship SPAN Smart Panel is the first true evolution for the traditional home electric panel, harnessing enhanced technology for metering, monitoring, and control. An expanded product suite of intelligent, integrated solutions radically lowers the cost and complexity of energy upgrades–including solar, batteries and EVs–empowering homeowners to be active, resilient and informed players in the energy market.

The Role

We are seeking an experienced mobile frontend technical leader to architect and drive SPAN’s mobile solutions. Our mobile apps are the key to unlocking the potential of the SPAN panel for our users by giving them insights and never-before-available control. As a senior staff or principal mobile engineer, you will evolve the mobile team’s technical culture and help build our apps into industry-leading customer experiences in millions of homes.


  • Guide and drive technical direction for SPAN’s mobile architecture

  • Drive and support the team’s commitment to code craft, cutting edge tooling, monitoring, and TDD

  • Design, implement, and test features in our React Native apps

  • Work closely with product and design on SPAN’s mobile product and execution strategy

  • Grow the knowledge of the team, sharing through pair programming, code review, presentations, example code, and documentation

  • Partner with firmware and backend engineers to influence seamless integration with our hardware product

  • Partner with QA and Platform Infrastructure to drive an efficient and robust quality system, and speedy, reliable deployments

As SPAN is a startup, this list should be considered neither exhaustive nor complete. This role will require agility and comfort to explore new areas of expertise and responsibility.

Potential Projects

  • Lead the team to define and socialize architectural best practices in advance of a major refactor

  • Collaborate with other functional tech leads on a full stack data transfer refactor to help us scale to millions of homes

  • Collaborate with product and the rest of the mobile team to iteratively deliver value in a predictable way against multi-year projects
