Senior Staff MLOps Engineer
Overview
We are rebuilding the energy transaction, making it transparent and fair. Our goal is to put power back where it belongs, in the hands of customers and to take on one of the most critical problems of our century, access to low cost electricity.
Job Description
tem exists to fix a broken global energy market that’s long favoured legacy operators, intermediaries, and opaque pricing. Today’s electricity system was not designed for rapid decarbonisation, AI-driven efficiency or fair access for the actual users - businesses and generators. We’ve built the first AI native transaction infrastructure to reinvent how electricity is bought, sold and priced. Our technology is designed to cut out the inefficient fees, automate complex market flows, and bring transparency and fairness to energy transactions at scale.
Responsibilities
- - Own the ML platform strategy: Define the roadmap from Level 1 to Level 2, making architectural decisions ahead of when they'd otherwise become blockers.
- - Keep the platform aligned to Rosso's commercial trajectory.
- - Build the foundations: Lead the design and build of experiment tracking, model registry, automated pipeline infrastructure, and production monitoring across all model types.
- - Deliver backtesting and shadow deployments: Build the infrastructure the forecasting and pricing teams need to validate models reliably against historical data and in production before they go live.
- - Set technical direction: Provide the architectural vision and standards the Senior MLOps Engineer executes against.
- - Partner across the team: Work closely with ML engineers and software engineers to understand what the platform needs to unlock the next wave of Rosso capabilities.
- - Choose the right tools: Evaluate the MLOps tooling ecosystem with clear eyes.
- - Drive deployment reliability: Push toward more frequent, reliable model deployment cycles as Rosso moves from batch-heavy workflows toward live, near-real-time processes.
- - Define best practices: Establish standards for how models are trained, versioned, deployed, and monitored across the team.
Required Skills
- - Scaled an ML platform from early-stage: Demonstrable experience taking an ML platform from early stages to best-in-class infrastructure at a fast-moving company.
- - ML pipeline expertise: Deep experience across the whole MLOps lifecycle with ML pipeline orchestration (Metaflow, Prefect, Airflow or equivalent) and ML infrastructure (Sagemaker, Vertex AI, Chalk, or equivalent).
- - Model lifecycle tooling: Hands-on experience building or operating experiment tracking systems (MLflow, W&B, or similar), model registries, and governance tooling for model fleets at scale.
- - Broad MLOps tooling knowledge: Across the ecosystem monitoring, drift detection, CI/CD for ML, containerisation, IaC (Terraform, AWS CDK).
- - Technical leadership track record: Evidence of setting platform direction, influencing cross-functional teams, and defining standards at Staff+ level.
- - Heterogeneous workload experience: Experience designing and operating platforms serving heterogeneous workloads (e.g. forecasting, classification, operations research, etc), not just one model type across batch and real time applications.
- - Python, AWS + IaC: Strong Python; hands-on experience with AWS and infrastructure-as-code (Terraform, AWS CDK).
About the company
tem is reinventing how the world transacts energy to make low-cost, transparent electricity universally accessible. Built to fix a broken wholesale system stacked with middlemen and hidden markups, tem uses AI to power a new transactions infrastructure that lets businesses buy electricity directly from renewable generators. Its flagship product, RED™, delivers fully auditable, transparent pricing—giving customers real ownership over where their energy comes from while ensuring fair compensation for generators. Since launching in 2021, tem has helped UK businesses cut energy costs by up to 30%, saved over £25 million across its network, and is backed by leading investors including Atomico and Albion as it builds a more direct, decentralised, and trusted energy market.
