Senior Software Engineer (Frontend - React/Angular)

Job Description

Uplight is creating a new category of energy. We make software that manages energy resources in homes and businesses-including things like smart thermostats, electric vehicles, solar panels, storage batteries, heat pumps, and even people's behavior-to generate, shift, or save energy to balance the grid, making it more efficient and reliable. This creates clean energy capacity that can be used by the power grid instead of burning more fossil fuels. Our solutions accelerate the transition to clean energy and save money for energy customers.

You will collaborate closely with backend engineers, product managers, designers, and stakeholders to deliver seamless, responsive, and intuitive user experiences.

You will be responsible for driving frontend best practices, performance optimization, code quality, and maintainability. This role requires strong architectural thinking, hands-on development expertise, and the ability to mentor junior engineers while contributing strategically to product and technology roadmaps.
