Senior Fullstack Engineer - TechOps

Octopus Energy started with a bold idea: to build Britain’s first truly digital energy supplier. By combining world-class tech with brilliant humans who care deeply about customers and driving the renewable energy transition, we became Britain’s largest energy supplier. Now, we’re scaling fast and building the next generation of products to accelerate the green energy transition.

At Octopus Tech, you’ll have real ownership, variety, and the chance to shape products that make a tangible difference in people’s lives – lowering bills, enabling greener living, and delivering experiences customers genuinely love. You’ll work side by side with teams across marketing, operations, and data, and see the impact of your work in the real world, fast.

We’re building a small and efficient TechOps Engineering team at Octopus. We are looking for an ambitious, knowledgeable and experienced Full Stack Software Engineer to join our team, to grow with the rest of the company, and build systems that our people love! You will be a key partner in defining what TechOps Engineering is at Octopus.

What is TechOps? A more modern, lean version of a traditional enterprise IT team. The team covers everything from what most people would call “1st line support” all the way up to high-level strategic planning, and everything in between.

We’re looking for a Full Stack Software Engineer to join our TechOps Engineering team, designing and building solutions to make our TechOps capability efficient, scalable and robust and available on-demand via self service.

What you’ll do:

• Creating solutions to problems such as Device Lifecycle management, Identity Verification and SCIM User Provisioning
• Tackle tough technical problems as we scale to tens of thousands of people
• Collaborate closely with our Security team to ensure we strike the right balance between security, productivity and user experience
• Develop applications and systems to improve the experience of our users
• Contribute ideas, share knowledge and raise the game of those around you
• Build APIs and integrate with our own and third party services to optimise and automate processes
• Care about the code you write and its future maintainability

What you’ll have:

• 5+ years experience in software development, with strong recent proficiency in React (Next.js), TypeScript and Tailwind/Panda CSS
• 5+ years experience database design and working with RDBMSs (e.g. PostgreSQL)
• Strong experience with modern testing frameworks (e.g., Vitest, Jest, Playwright, Cypress, or similar)
• Strong skills in source control (we use GitHub)
• A track record of taking ownership of the development of features from inception through to delivery
• DevOps experience (Build/Test/Deployment pipelines using GitHub Actions/CircleCI)
• Experience working with design systems and component libraries
• Experience working with 3rd party providers to consume APIs
• Experience designing intuitive and simple User Interfaces
• An ability to understand and explain complex technical problems in clear, simple concepts and language to both technical and non-technical people
• Excellent understanding of fundamental coding principles and best practices and experience applying these to create robust, scalable, maintainable software

Experience in any of the following would be a bonus:

• Familiarity with Workflow DevKit and Vercel
• GraphQL and API technologies (REST, Webhooks)
• Scripting experience (such as Bash or PowerShell)
• AWS services including Secrets Manager and Elastic Container Service (ECS)
• Experience with Cloud Security Posture Management (CSPM) and vulnerability management tools such as Wiz or Snyk
• Designing distributed systems, improving service reliability (SRE), and contributing to long-term architectural strategy
• Native application development using Swift
• Identity and Access Management (IAM), including IdP management and platforms such as Okta
• Provisioning and certificate protocols such as SCIM and SCEP
• Endpoint and Mobile Device Management tools such as Kandji, Microsoft Intune, and Apple Business Manager
• Zero-trust device compliance and asset management practices
• Endpoint compliance and security tooling such as Kolide
• Physical security systems such as Verkada (CCTV/access control)
• Experience with enterprise SaaS tools such as Slack and HiBob
• Networking fundamentals, ideally with Cisco systems
• Hardware and device lifecycle management (e.g. IRU / device procurement)
