Senior Software Engineer – Industry Platform Team
As a Senior Software Engineer on the Industry Platform team you will be responsible for architecting, implementing, and supporting integration solutions that connect internal and external applications. You’ll work closely with the rest of the team and others inside and outside the Technology department to deliver scalable APIs, services, and applications that enable seamless interoperability.
A typical day would start with stand‑up, sprint planning, or retrospectives where you’ll collaborate with the team to align on priorities and unblock progress. From there, your time might be spent deep‑diving into code, debugging issues, refining future work, or reviewing the code of your colleagues.
You’ll often work cross‑functionally, engaging with product owners, solutions architects, data engineering or stakeholders from other departments to clarify needs and ensure that what you’re building delivers real value. Some days are more collaborative, others are heads‑down and focused—whether you’re writing clean, scalable code, reviewing pull requests, or exploring ways to improve performance and reliability.
We value autonomy, curiosity, and a pragmatic approach to problem‑solving. You’ll be trusted to own your work, contribute ideas, and help shape how we build software that helps us achieve our mission of a greener Britain.
About You
You will need to be comfortable working on different value streams, with different stakeholders, sometimes switching between them as priorities and blockers come up. You’ll be very experienced both consuming and building API endpoints.
You should have good experience of AWS; currently we’re using Lambda, DynamoDB, API Gateway, Step Functions and more.
The code we’re writing is mostly TypeScript transpiled for Node.js and deployed using CDK.
We’re aware that every company uses different tooling, so if you’re not familiar with all the technologies we use, that’s okay. However, a good understanding of the concepts and willingness to learn is a must.
As a disruptive company wanting to make ‘Britain Green’, a passion for sustainability and environmental issues is a bonus. As is experience of the energy industry, billing and finance.
