Company mission

To enable homes to get clean energy faster, cheaper and more easily. Impacting climate change is our passion.

Role

Who you are

  • Proven experience as a Software Engineer
  • Proficiency building reliable and maintainable tools and services in Python
  • Proficiency in one of SPAN’s coding language: Python, JavaScript and frameworks such as ReactJS, React Native, Detox (or Appium), and Kotlin
  • Strong knowledge of software testing methodologies, test case design and automated testing
  • Experience with CI/CD tools and Github (i.e, CircleCI, Docker)
  • Effective communication and collaboration skills
  • Ability to work independently and as part of a team
  • Comfort building and working in greenfield automated testing frameworks and infrastructure

Desirable

  • Experience working in a startup environment
  • Experience with or preference for a rapid or continuous release cadence
  • Familiarity with Agile/Scrum development processes
  • Experience w/ GraphQL or GRPC, RDBMS/SQL, S3 and AWS
  • Experience working in the Renewable Energy industry

What the job involves

  • As a Software Engineer you will play a crucial role in ensuring the quality and reliability of our products through a combination of automated and manual testing methodologies
  • This is a high impact role that will work closely with SPAN’s internal Software, Device Software, Hardware Engineering, Systems and QA teams
  • Develop and maintain automation framework, driver library and consumer facing dashboards
  • Supporting DSW with HITL testing, Reliability, QA and Systems testing
  • Document defects, issues, and enhancement requests clearly and concisely
  • Participating in requirements review and systems engineering planning to determine high-leverage opportunities for automation
  • Working with the firmware team to ensure that engineering SDKs to the hardware have required capabilities for automated tests (e.g., structured log capture). Working with the firmware, systems and hardware teams to efficiently triage issues
  • Commissioning, standing up, and maintaining a worker pool of hardware test cells (‘device under test’) for DVT and production hardware. Worker pool capacity planning and commissioning of new test cells as usage and wait time increases
  • Reliable on-premise workflow scheduling and orchestration of test sequences on hardware, and the integration of these workflows to engineering CI/CD systems
  • Machine specification of test scenarios and acceptance criteria, and traceability with external requirements management tools (Jama)
  • Storage of raw log data to external object storage (S3), and structured test result data to Postgres (Currently done with Chronos)
  • Reporting web dashboards that provide clarity around pass/fail criteria for software releases, as well as other leading, non-deterministic reliability indicators (e.g., ‘crashiness’). Ensuring that these dashboards surface critical failing cases to the engineering team and that underlying issues can be efficiently identified
  • Monitoring of both physical test cell and web infrastructure uptime, capacity and reliability
  • Identify areas for process improvement and actively contribute to enhancing software development and testing practices pertaining to automation

Our take

Span helps homeowners looking to improve their energy resilience by replacing electric panels, many of them decades old, with a flexible smart panel that helps users monitor and control their energy usage from a single app.

Founded in just 2018, Span has made great strides in both price and technological development and has won the International Builders' Show 2022 Best Energy Efficient Product award for its Gen 2 smart Panel. Significant funding rounds have propelled product development, including a future-looking integration of its equipment with that of solar inverter, battery, and EV charger manufacturers.

This fast-developing and innovative answer to a previously stagnant home energy feature directly caters to the increasing demand for energy efficiency in the home. This is exemplified by a 2024 partnership with PulteGroup, the third-largest homebuilder in the US. With CEO Arch Rao at the helm, previously head of Products, Application & Sales Engineering at Tesla, Span seems likely to continue on its winning streak with increasingly affordable renewable energy products.
