Software Engineer Python AI - Renewable Energy

London, Greater London | £90k - £120k per year

Software Engineer / Business Systems (Python AI) London / WFH to £120k

Are you a technologist Software Engineer with commercial AI experience who enjoys getting close to real business problems, building solutions quickly and taking them into production?

You could be progressing your career at a rapidly scaling renewable energy business at the forefront of the transition to a more flexible, technology enabled energy system. With a growing portfolio of wind and solar assets across the UK, the business is expanding into energy trading and investing heavily in technology, automation and AI.

As a Software Engineer, you'll work across the business, partnering with teams spanning Development, Project Delivery, Investment, Asset Management and Trading. You'll investigate real workflows, understand the underlying data and systems and determine whether AI, conventional software, automation or process change is the right solution.

Collaborating with the AI Lead and domain specialists, you'll take ambiguous problems from discovery through rapid prototyping, testing and evaluation, before taking successful solutions into production. You'll work directly with users, prototype using real data and build production software across Python, APIs, data integration and lightweight frontends, incorporating LLMs, retrieval, tool use and agentic workflows where they add genuine value.

You'll own your solutions through deployment and early production operation, including testing, security, permissions, monitoring and resilience. Alongside individual products, you'll help establish the company's first reusable AI engineering capabilities, developing practical patterns for model access, deployment, evaluation, observability, CI/CD and production AI.

This is a high-autonomy role for a highly capable engineer who enjoys ambiguity, moves quickly from idea to PoC and takes genuine ownership of outcomes. You'll work with exceptionally bright people and have the opportunity to shape both the technology and engineering culture as the AI capability grows.

Location / WFH:

You'll be based in the London office with flexibility to work from home twice a week.

About you:

• You have a strong knowledge of software engineering fundamentals and experience of designing, building and operating production software
• You have strong backend Python coding skills
• You have practical experience applying LLMs, retrieval, tool use or evaluation
• You have sound product judgement and the ability to work directly with technical and non-technical users, ask useful questions and make sensible trade-offs
• You're comfortable moving between fast experiments and maintainable production code, with a pragmatic view of build versus buy
• You're keen to take ownership and have the drive to solve difficult problems
• You've achieved a 2.1 or above from a top tier university (e.g. Russel Group) in a STEM discipline

What's in it for you:

• Salary to £120k
• Pension
• Impactful role with excellent progression
