Lead Product Marketing Manager
📈 Who We Are:
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.
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.
In late 2025, after extraordinary growth, we closed a $75 million Series B - led by Lightspeed Venture Partners with participation from Albion, Atomico, Allianz, Hitachi Ventures,, Hitachi Ventures, Schroders Capital and others - positioning us for global expansion, deeper product innovation and category leadership.
We’re scaling internationally and building toward a future where AI-driven infrastructure is foundational to electricity markets worldwide.
Since launch, our modern utility product, known as RED, has already facilitated thousands of business customers and billions in energy transaction value, proving that modern software and AI can transform an industry built on legacy systems.
At tem, we’re not just building another energy company, we’re rearchitecting market infrastructure so that transparency, efficiency and sustainability become the default, not the exception.
🏅 The Role
We're hiring a Lead Product Marketer. Your job is to help lead marketing for tem's core energy products, from foundational strategy to world-class execution, and raise the standard of everything that goes out the door.
This is an expert role with no direct reports. It exists because our product marketing function needs someone who can own the positioning, build the infrastructure, and set the quality bar for product launches and our underlying product marketing infrastructure.
You will share ownership of tem's product marketing portfolio alongside another senior PMM. Together you support the credibility service across the company, as well as directly supporting our Payments, Invoicing, Integration, Sell, and P442 features, and share responsibility for the foundational infrastructure and PMM framework that supports all engines. You will build the materials commercial teams depend on: ICPs, value propositions, battle cards, messaging docs, product decks, and launch playbooks. You will define how we go to market for new features and products. And you will be the person who makes the whole marketing team better at product marketing through the quality of your thinking and your output.
You work closely with the Product team, Commercial leads, and the Growth Manager. You operate with senior scope and are expected to bring strategic clarity and executional excellence in equal measure.

A note on AI usage
We're an AI-first company. We expect candidates to use AI tools. But we want to see judgement, not just output.
Use AI if it helps. But:
Be honest: Show us what AI generated and what you created or edited.
Show judgement: We want to see where you override AI and why.
Be practical: What tools? What prompts? What actually worked vs. in theory?
Maintain quality: AI-accelerated ≠ AI-written. Your thinking is what we're hiring.
If you don't use AI, tell us why. That's a legitimate choice if you have reasoning behind it.
We welcome applications from people of all backgrounds, experiences, and identities, including those that are traditionally underrepresented in the tech and energy sectors. If you’re excited about this role but not sure you meet every requirement, we’d still love to hear from you. Your unique perspective could be exactly what we’re looking for.
