Backend/Full-Stack Engineer - Internal Tools | Physical AI Scale-Up
Blue Wolf Digital is working with a fast-growing physical AI company to find a Backend/Full-Stack Engineer for their Internal Tools team. This one's a great fit if you want real ownership, a modern stack, and a front-row seat at a company that's just closed funding and is scaling quickly.
A Bit About Our Client
They're building the next generation of physical AI - technology designed to keep critical infrastructure safe, secure, and sustainable. Their current focus is genuinely interesting: using federated AI to optimise energy usage in data centres, by sending algorithms to the data rather than the other way round. It's a smart, resource-efficient approach, and their flagship product — an AI-driven cooling efficiency application - runs on their own in-house distributed AI platform.
They've just closed a funding round and are in growth mode, which means this is a good moment to get in.
The Role
Their R&D team is split into four areas - Platform, their flagship product, Surrogate Modelling, and Internal Tools. This role sits within Internal Tools, a small team responsible for the systems that power how their core product gets deployed, operated, and supported. You'd be building production-grade tools across the stack - web apps, APIs, cloud infrastructure, CI/CD - on a modern Python and TypeScript codebase, with genuine end-to-end ownership of features that directly affect how the business scales.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
What's Involved
- Working closely with the VP of Product and the Internal Tools lead on feature and product design
- Estimating and delivering features in an Agile environment
- Mentoring more junior engineers as the team grows
- Occasionally supporting customer-facing issues
Who They're Looking For
An experienced engineer - 5+ years in software development, ideally in a product-focused environment - who cares about doing things properly rather than just shipping quick fixes. Someone self-motivated, comfortable working autonomously, and keen to join a scale-up where they can genuinely shape the product and the team, not just execute tickets.
