About the team

Bulb is here to help our members cut their energy bills and reduce their carbon emissions. Our product teams make that happen. We’re developing products that will deliver the future of energy - from using AI to read energy meters, to making carbon offsetting fun and simple, from finding out how to get the most from Smart Meter data to helping people get paid for their solar energy. We also power the sign-up journey that helped us become the fastest growing company in the UK last year and the internal tools that let us deliver a Trust Pilot score of 9 out of 10.


At Bulb we want to hire people with the experiences necessary to get going quickly, but who are also interested in learning new things and are comfortable working in a changing environment.

Identifies and plans strategic improvements across operation of multiple pods / organisation
Help us hire and onboard senior and specialist roles and support the growth of engineers across multiple pods.
Bootstraps new pods ensuring technical alignment at an early stage.

Tech Stack

At Bulb we use a wide variety of technologies. While we have core technologies that we work with, we're always trying to pick the best tool for the job, and are always looking at what's on the horizon.

Our stack currently includes, but is not limited to:

Node, Typescript, Koa, Redux, React, React Native, Webpack, Babel, Flow, GraphQL
Circle CI, Kubernetes, Docker and Google Cloud Platform
Ideally, you would be familiar with these technologies or similar patterns; notably, Typescript/Javascript coupled with React is a core technology for us. But we’re more interested in your broad experience of software development than of specific tools or libraries. You should be comfortable getting up-to-speed quickly in new tools and platforms. You should be pragmatic and experienced enough to know when a different choice of technology would be more suitable, and comfortable leading explorations into new technologies.

Team Structure

Teams at Bulb are cross-functional, self-organized and autonomous pods. The key features of this structure are:

You’ll be working within a growing cross functional team composed of specialists with backgrounds in DevOps, Engineering and Security.
We practice Scrum/Kanban and work lean.
Work is not siloed, you’re able to commit across the stack, and you have a view of all the features the team are working on.
We use data to drive continuous improvement in our development process and we review this data in our fortnightly retrospectives.
We reflect the Bulby working culture.
