Job summary

Fuse Energy is building a cutting‑edge AI team and an applied AI engineer will own the Product Factory, delivering AI features from requirements through code, deployment and monitoring. You will ship customer‑facing capabilities using LLMs and tools, while building scalable, secure AI infrastructure for support, trading and operations.

You will collaborate with teams across energy pricing, weather and demand forecasting, and back‑office processes.

Qualifications

• 3+ years of experience in applied AI, with end-to-end ownership.
• Experience owning an applied AI system end to end, ideally in a startup or small team, and able to explain what broke and how you knew it worked.
• A software engineer who moved into applied AI, or an ML engineer who writes production code.
• Strong Python (or similar) and experience deploying LLMs or VLMs into production.
• Solid understanding of cloud technologies, containerisation and scalable AI applications.
• Analytical, rigorous and quick to learn. You don’t need our exact tools, just the ability to pick them up.
• Bonus: PyTorch or TensorFlow; forecasting, weather and demand modelling; energy markets and trading; fine-tuning or RL; vision, document or NLP pipelines; agent runtimes.

Responsibilities

• Ship AI features for customers, such as personalised energy recommendations and onboarding from an energy bill.
• Build LLM applications and agents for support, engineering, warehouse and back-office teams, including multi-agent systems and durable workflows (e.g. Temporal).
• Build the engineering around them: cloud infrastructure, integrations, and access control so users and agents only reach what they should.
• Own evaluation: datasets, golden answers, human and LLM judges, A/B tests. Know whether a change genuinely helped.
• Choose models by performance, latency and cost, and revisit as models improve.
• Work with trading, operations and backend teams so models reflect real-time market conditions, energy pricing and demand and weather forecasts.
• Monitor AI systems in production and keep them reliable.
