Job summary

Neutreeno is seeking a Decarbonisation Model Engineer to lead system-level modelling of technologies and processes that cut emissions and cost across complex industrial settings. You will build bottom-up models, quantify energy and material efficiency opportunities, and develop techno-economic analyses to support strategic decisions.

Working across jet engine production, electricity transmission and EV battery manufacturing, you will model CAPEX/OPEX, carbon pricing, and green finance,

Qualifications

• Masters or PhD in Industrial, Chemical, Process or Mechanical Engineering.
• 3+ years of industry or research experience in techno-economic modelling, with a strong focus on energy and material efficiency and emissions reduction.
• Proven system-level thinking: able to reason about whole systems and identify where the biggest opportunity sits, rather than optimising components in isolation.
• Deep working knowledge of energy and material efficiency in industry: heat integration, electrification and fuel switching, and how material flows, yield losses and substitution drive embodied emissions.
• Strong command of carbon accounting and life cycle assessment, including Scope 1, 2 and 3 inventories, product carbon footprints and the relevant frameworks (GHG Protocol, ISO 14064 / 14067, SBTi, CBAM).
• Costing proficiency across techno-economic analysis (capex/opex, abatement cost, MACCs), project finance (NPV, IRR, payback, discount rates) and carbon pricing (ETS, carbon taxes, internal shadow prices).
• Expert Python for quantitative modelling (pandas, NumPy), with the discipline to make models reproducible, validated and version-controlled (Git/GitHub).
• Familiarity with using LLMs and agentic-AI workflows to build and enhance decarbonisation roadmaps.
• Outstanding communication skills, with the ability to convey technical concepts to both technical and non-technical audiences.

Responsibilities

• Build bottom-up models from first principles that calculate bespoke decarbonisation levers at scale, accounting for cost, dependencies and implementation time.
• Quantify energy and material efficiency opportunities, from heat recovery, electrification and utilities to yield losses, material substitution and circular design while identifying Best Available Technologies (BAT) for technology-specific cases.
• Develop the techno-economic analysis behind each lever: CAPEX and OPEX, cost of abatement, marginal abatement cost curves, and sensitivity analysis that stands up to a client's finance team.
• Develop our carbon pricing engine across the current pricing landscape (compliance markets, taxation, internal shadow pricing, CBAM) and model client exposure under different price scenarios.
• Identify where decarbonisation creates value, including green premium pricing for low-carbon products and access to incentives and green finance.
• Write clear, reproducible Python behind the models and mentor junior engineers.
