Job description

Do you want to shape the engineering foundations of products that help power everyday life for 8 million people?

Northern Powergrid is investing in a new in-house software engineering team, and we are looking for senior engineers to set its technical standards from day one. As the energy system transforms, we have decided to own our own destiny: designing, building, and owning key digital products ourselves. You will join the newly formed Software Engineering Team at the very start of that journey.

You will design and build modern, cloud-native web and mobile applications and the API layers that bring together business data from across our technology estate, enabling colleagues across the business and integration with partners across the energy industry. Our work spans applications used by our field staff, systems that support engineering and design, improving our customer experience, and planning our network, and the scope will grow substantially as our capability matures into the next regulatory period (ED3).

This is a role for an engineer with real breadth. You will be one of the people the team turns to on complex technical problems, working across the front end, the back end, the APIs, and the cloud rather than specialising narrowly in one of them. You will also work beyond our own walls, with the suppliers and delivery partners who build alongside us and with the wider technical community, and bring what you learn back into how we build.

We are also deliberately building a human-led, AI-accelerated engineering culture. We want experienced engineers who are curious about using AI and emerging agentic tools to reduce friction, explore options, and improve delivery flow, while keeping clear human accountability for design, security, testing, and maintainability. The aim is a practical builder model: engineers close to the problem, empowered by modern tools, and disciplined about quality.

Along with a competitive salary of between £65,000 - £75,000 we also offer:

• Annual leave of 25 days + bank holiday entitlement
• Enrolment into our Pension Scheme, with a generous company contribution (6% employee / 12% employer)
• 15% Performance Bonus
• Excellent career development as a senior founding member of a growing team

Key Responsibilities:

• Lead the design and delivery of services and features: Across a modern stack (React/TypeScript front ends, .NET back ends, with flexibility for the right tool).
• Help deliver mobile applications for our field teams: built with React Native alongside our web stack, so that colleagues working out on the network have tools that work wherever they are.
• Design and build APIs and abstraction layers: Integrate data from a mixed technology estate (.NET, Node.js, SQL Server, Oracle, Databricks, and more), so that our products and our partners can use business data without being coupled to the systems underneath.
• Own quality: Practising and championing test-driven development, automated testing, and CI/CD, so that we can change our systems quickly and safely instead of slowing down as they grow.
• Build and operate containerised services in the cloud: Primarily Azure with some AWS and OCI, so that what we build runs reliably and we stay accountable for it long after release.
• Use modern AI-assisted engineering tools to accelerate delivery: Applying professional judgement to review, test, and validate all code regardless of how it was produced, so that we gain the pace without lowering the bar on quality or accountability.
• Help shape practical AI-assisted and agentic engineering patterns for the team: Covering coding, testing, documentation, workflow, and developer experience, so that we adopt these tools deliberately rather than each engineer working it out alone.
• Mentor engineers through code review, pairing, and design discussion: Ensuring the standards we set at the start still hold as the team grows.
• Work with colleagues, suppliers, delivery partners, and our Product and Innovation teams: Turning business problems into well-engineered, pragmatic solutions, so that what we build addresses the real problem rather than the first version of the request.
• Contribute to technical decisions on architecture, tooling, and ways of working: Ensure what we build follows the policies, procedures, and regulatory requirements that apply to us, so that early choices still stand up as the estate grows and we stay compliant as an operator of critical national infrastructure.
• Significant experience across the discipline: You are a go-to engineer within the team on complex technical matters, with breadth across the stack, covering front end, back end, APIs and cloud.
• External and Internal exposure: You will work with or suppliers nad delivery partners and engage with the wider technical community outside Northern Powergrid, bringing what you learn back into how we build.
• Influence within Digital and Innovation: You will shape technical decisions well beyong your own work, and carry the credibility to influence senior colleagues across the directorate.
• Responsibility for policy and regulatory adherence: You will make sure the software we build follows our policies and procedures and the regulatory and legislative requirements that apply to us as an operator of critical national infrastructure.

Qualifications and Experience:

• Degree in a relevant subject, or equivalent practical experience.
• Significant experience building production software, typically five years or more, including ownership of services running in production.
• Breadth across the stack, covering front end, back end, APIs, and cloud, with the confidence to be a go-to engineer on complex problems.
• Strong experience designing and building APIs and integrations.
• Strong automated testing experience and a commitment to test-driven development.
• Experience with containerised applications and at least one major cloud platform (Azure preferred).
• Practical experience of AI-assisted development, or a strong interest in applying these tools responsibly to improve engineering flow, code quality, and delivery pace.
• Track record of mentoring engineers and raising quality through code review.
• Experience working with external partners, suppliers, or the wider technical community, as well as within your own organisation.
• Clear communication with technical and non-technical stakeholders, with the credibility to influence senior colleagues within a technology directorate.
• Experience with React/TypeScript and .NET (C#); strong engineers from comparable stacks (Java, Node.js, Python) are very welcome.
• Experience shipping mobile applications, ideally offline-capable (React Native preferred).
• Experience integrating with or abstracting over legacy or vendor-managed systems.
• Experience with infrastructure-as-code, observability, and DevOps practices.
• Experience in regulated industries, utilities, or other critical infrastructure.
