Full Stack Engineer

You’ll be joining a fast-growing, Manchester‑based energy tech company that is reshaping how businesses buy and sell renewable power. Their peer‑to‑peer energy exchange platform connects organisations directly with renewable generators, using AI and modern cloud technology to cut out the traditional wholesale market, reduce costs, and make green energy more transparent, local and accessible.

What you’ll be doing

• Leading the design, development and delivery of customer‑facing and internal applications using React + TypeScript.
• Architecting and implementing APIs, microservices and serverless functions in Node.js on AWS (Lambda, API Gateway, DynamoDB, SQS/SNS, S3), with a focus on scalability, reliability and maintainability.
• Proactively identifying technical improvements, bottlenecks and opportunities to enhance systems, workflows and engineering practices.
• Collaborating with product, design and operations teams to translate complex requirements into clear technical solutions.
• Driving code quality through strong testing practices (unit, integration, e2e, load), code reviews and automation.
• Mentoring junior and mid‑level engineers, helping them grow and raising the overall technical bar.
• Contributing to the technical roadmap and architecture, and taking ownership of technical debt, performance optimisation and long‑term maintainability.

What we’re looking for

• Extensive commercial experience with Node.js/TypeScript.
• Strong experience building and deploying services on AWS (Lambda, API Gateway, DynamoDB, SQS/SNS, S3).
• Deep understanding of REST APIs, event‑driven architectures and distributed systems.
• Proven track record of delivering projects independently and resolving complex technical challenges.
• Strong experience with testing strategies (unit, integration, e2e, load).
• Demonstrated ability to mentor engineers and lead the delivery of complex features from concept to production.
• Excellent communication and collaboration skills, including working confidently with non‑technical stakeholders.

Nice to have

• Experience with Infrastructure as Code (Terraform, AWS CDK).
• Advanced knowledge of serverless architectures and distributed systems.
• Experience integrating complex third‑party APIs and data sources.
• Knowledge of energy/utility industry workflows (e.g. smart meters, billing, pricing).
• Experience in technical leadership, architecture design and shaping engineering practices.
• Degree in Computer Science, Software Engineering or related field (or equivalent experience).
