Job description

Axion Lab is anAI-native sustainability services firmfor GPs and their portfolio companies. We are building a new kind of product and service for alternative asset managers – turning high-end sustainability expert work into a continuously available, software-native experience an investment team can actually use.

The focus is the cross-portfolio sustainability value-creation assessment and roadmap steering through the holding period. We also deliver sustainability reviews, due diligence, carbon footprints and decarbonisation reports, as add-on offerings.

Our platform combines AI with expert judgement. AI handles the more deterministic parts: data extraction, analysis, modelling, benchmarking and calculations. Sustainability experts focus on the judgement-heavy parts: selecting assumptions and methodologies, interpreting edge cases, challenging conclusions and validating outputs.

The role

1. Deliver projects and learn from delivery

This will be the initial focus.

• Scope and deliver engagements for GPs, portfolio companies and lenders, such as clear workplans, robust analysis and decision-ready deliverables that show where sustainability issues create or protect value; you own quality, timing and final presentation
• Feed what you learn back into the platform: every project adds to the data flywheel that makes the next delivery faster and better

2. Productise and replicate what works

This will grow as we complete projects together.

• Deconstruct consulting approaches into repeatable steps, i.e., what AI can standardise, what must remain expert judgement; and turn them into practical specifications for product and engineering
• Turn project lessons into reusable methodologies, prompts, templates, checklists and quality standards, tested against real client work

As one of the first sustainability delivery experts, you will build these foundations directly rather than inherit or manage an existing team.

What we are looking for

• 5+ years of combined experience in sustainability, ESG, climate or strategy consulting – e.g., at a sustainability consultancy (ERM or similar), a Big 4 firm, a strategy consultancy (MBB or tier-2) or a sustainability role inside a private equity fund. Mixed backgrounds are very welcome.
• Practical understanding of private markets, including how GPs, LPs, investment and portfolio teams, lenders and portfolio companies work together, and how their sustainability needs differ across the investment cycle
• Working knowledge of widely used global sustainability frameworks and methodologies and regimes, such as ISSB/IFRS S2, TCFD, GHG Protocol, SBTi, CSRD/ESRS, SFDR, EU Taxonomy, UK SDR is a plus
• Familiarity with sustainability value creation for portfolio companies, not only reporting or compliance
• Readiness to work the way a tech company works: write things down as clear specs, iterate in short cycles, and give structured, example-driven feedback; you do not need to be a software engineer
• Practical experience using generative AI in professional work, or strong evidence of the willingness and ability to learn quickly

If you do not tick every box but bring the right mindset, problem-solving skills and the ability to iterate fast, we would still like to hear from you.

• Work directly with the co-founders to shape our services, product priorities and delivery model, and with partners and directors of leading funds and C-level teams of their portfolio companies, in Europe and globally
• Combine hands-on client delivery with service design and AI experimentation, and put your skills at the front of the market: experience in AI-native expert work is rare, and valuable wherever you take it next
• Work with meaningful autonomy from day one

Working model

The role is primarily remote and should be compatible with European working hours. Occasional in-person meetings may take place in Paris, London, Luxembourg or Amsterdam, as well as elsewhere in Europe depending on client and team needs.

You would work with

• a Strategy & Private Equity Expert on commercial and financial framing, i.e., how the analysis looks to an investment committee or a lender
• a Sustainability Partner who typically owns the client relationship and signs off
• the founders and the product team (engineering and design), who turn your delivery lessons and platform feedback into product improvements
