Job Description:

tem is a next-gen energy transactions company that changes the way renewable energy is bought, sold and powered. Rebalancing the playing field away from "Big Energy", tem creates affordable, traceable and smart energy transaction management tools.

tem is at a critical scaling point - our new FP&A function will be pivotal in building and delivering the financial strategy to ensure confident, data-driven growth. You will drive the planning cadence, scenario and revenue modelling, and become the “go-to” partner for leadership on all things growth, economics, and risk.

Responsibilities

• Own all revenue, margin, and scenario modelling to power strategic, commercial, and product decision-making.
• Drive company financial plan—working with Exec, Growth team and Board—to update and iterate on modelling as tem evolves and scales.
• Partner with Product, Data, Commercial, and Operations to track and make sense of platform growth, customer metrics, and commercial performance.
• Own Board and investor pack financials: ensure data integrity, clarity, and strategic value in every update.
• Support investor comms and fundraising—producing forecasts, scenario models, and financial narratives that instill confidence.
• Build, lead, and mentor a growing FP&A function: set the tone on quality, rigor, and alignment to tem’s growth ambitions.

Experience Required

• Scale up experience (has been with a company from Seed/Series A/Series B through to scaleup)
• Strategic finance leadership (FP&A or equivalent) roles in high-growth or scale-up environments (e.g. marketplace, fintech, SaaS, energy, etc.)
• Ownership of financial strategy and Board/Exec partnership in fast-evolving business.
• Direct involvement in fundraising, Board comms, or investor relations is highly valued.
• Experience running budgeting, planning, and economic modelling for new commercial/offering launches and international expansion.

Skills Required

• Complex Financial Modelling: Build, iterate, and enhance highly complex financial models to support revenue forecasting, margin analysis, scenario/sensitivity planning, customer value, and pricing.
• Strategic Forecasting: Own and continuously improve rolling forecasts, aligning them to evolving business units, product lines, and GTM initiatives.
• KPI & Metric Design: Design and deploy commercial and operating metrics (e.g. ARR, win-rate, lifetime value, customer savings) to track performance, de-risk GTM, and support Board/investor reporting.
• External Narrative Building: Articulate complex financial results and opportunities for external stakeholders, including current/prospective investors and Board members.
• Stakeholder Partnership: Work cross-functionally to embed financial logic into decision-making, enabling smarter resource allocation, prioritisation, and trade-offs.
• Tooling Proficiency and Data Hunting: Work with Data Analytics to identify, define and extract required data. Expertise in Google Sheets/Excel, with experience in business intelligence platforms.
