The Role
We are looking for an Applied ML Scientist to join the ACE team and work on
reinforcement learning applied to real, physical infrastructure. You will help develop,
train, and harden RL agents that operate in live data centre environments, working
across the full arc from problem formulation and model training through to federated
deployment and inference on customer sites. The work sits at the intersection of
machine learning and engineering: you will spend as much time reasoning about
thermodynamics, equipment behaviour, and operational constraints as you do about
model architectures and training dynamics.
Duties and Responsibilities
• Design, train, and evaluate reinforcement learning agents for control problems
in data centre environments.
• Translate messy, real-world telemetry into well-posed ML problems, including
state and action design, reward engineering, and constraint handling for safety-
critical operation.
• Sanity-check model behaviour against physical first principles and catch
unrealistic results before they propagate downstream.
• Work alongside software engineers to productionise models on the OctaiPipe
platform, including federated training pipelines, on-site inference, and
monitoring of deployed policies.
Restricted
• Support the team's research agenda, including collaborations with academic
partners and (where appropriate) external technical write-ups.
OctaiPipe is an AI-powered optimisation software solution that delivers up to 30% savings in cooling energy use with zero disruption. It reduces costs, emissions, and water usage—helping data centres improve PUE, meet sustainability goals, and comply with global standards like ISO 50001, EED and CSRD. With pricing calibrated to energy savings, typical payback is under 3 months. For a 5MW site, OctaiPipe can cut over €600,000 in annual costs, reduce PUE from 1.42 to 1.30, and avoid more than 800 tonnes of CO₂.

No applications, no recruiter spam. Just the intro.
A few questions to make sure this role is the right shape for you. Two minutes.
I write the intro, send it to the founder, and handle the back-and-forth.
If they’re a yes, I book the chat. You show up — that’s the whole job-hunt.
