Job Description

Staff Data Scientist focusing on first-principles modelling and optimisation for renewable electricity contracts. Building core algorithms for efficient energy market transactions.

Responsibilities:

  • Own and build core optimisation systems: Design, implement, and operate ML and optimisation models that power pricing, matching, and allocation within Rosso and related systems, from research through to production.
  • Solve complex applied problems: Develop linear programming and optimisation solutions for batch and near–real-time use cases, balancing cost, risk, portfolio constraints, and commercial outcomes.
  • Ship production-grade models: Build and maintain end-to-end ML and optimisation pipelines in the cloud (AWS preferred), ensuring robustness, explainability, and operational reliability.
  • Develop core IP in-house: Replace third-party logic with high-quality internal implementations, iterating quickly as product and market understanding evolves.
  • Collaborate and influence: Work closely with product, engineering, and commercial teams to translate business needs into effective technical solutions, communicating clearly with non-technical stakeholders.
  • Raise engineering standards: Contribute to best practices in modelling, experimentation, and code quality, and provide informal mentorship to junior engineers and data scientists.

Requirements:

  • Strong optimisation background: experience with linear programming, operations research, or constrained optimisation in real-world systems.
  • Hands-on ML / data science experience: proven ability to build and ship models that matter.
  • Production mindset: experience designing, deploying, and maintaining cloud-based ML or optimisation systems.
  • First-principles thinking: comfortable working in ambiguous, greenfield problem spaces.
  • Strong Python skills and experience with the standard data science stack.
  • Commercial awareness: understands how technical decisions translate into business impact.

Benefits:

  • Competitive salar
  • Stock Options
  • 25 days holiday + public holidays
  • Remote & flexible working
  • Home working & wellbeing budgets: Up to £1,200 / €1,200 annually to upgrade your remote setup (co-working passes, equipment, etc.). Up to £150 / €150 monthly on anything that supports your wellbeing - from therapy to gym memberships to meditation apps.
