Backend Software Engineer

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 a backend software engineer to join our team building the cloud-based glue that gives our users access to the rich information and controls provided by the Span Panel. Our system collects a large volume of energy monitoring data that needs to be stored, processed, and exposed in different ways for different end-users. We're also opening up never before available levels of control of the energy in the home that need to be accessed in secure and easy-to-use APIs.

You’ll join our cloud software engineering team and work with other engineers including mobile, device (firmware), and systems software teams. Working with the team you’ll lead the design and implementation of systems that integrate our hardware, mobile apps, dashboards, and external APIs. You'll work with product owners and other engineers to build features from start to finish. Since the team is small you'll quickly become the go-to person for features you work on.

Responsibilities

• Design and develop new features and subsystems in the Span Cloud to support a variety of end-users
• Work cross-functionally with product and design teams to learn about our customers, identify solutions and develop the features that solve their needs
• Collaborate between firmware, frontend, and backend engineers on projects to seamlessly build a cohesive product
• Work in our TypeScript cloud with GraphQL and REST APIs communicating with IoT devices over AWS tools and MQTT
• Designing APIs and data specifications for internal and external users
