Mantel is developing the first molten-salt-based carbon capture technology designed to operate at the high temperatures found inside boilers, kilns, and furnaces - enabling highly efficient carbon capture that has not been possible until now. Carbon capture can be applied across industries to reduce emissions and achieve net-negative emissions. By solving for efficiency Mantel can cut costs substantially, unlocking carbon capture's role in reaching net zero emissions by 2050. To learn more, go to: https://www.mantelcapture.com/

The Senior Commercial Counsel was designed for a specific kind of lawyer: one who has spent years in transactional practice, is genuinely good at it, and wants a bigger stage. As Senior Commercial Counsel, you'll own Mantel's contracts function end-to-end – Master Service Agreements (MSAs), licensing agreements, term sheets, offtake deals - while also having a real seat at the commercial strategy table. You'll shape how deals are structured, not just document them after the fact.

This is the right role for a lawyer who finds pure legal practice too narrow. You'll be a genuine partner to the business, not a reviewer at the end of the process.

What you'll do:

1. Contract Ownership

•       Own Mantel's commercial contracts end-to-end: draft, negotiate, and close MSAs, NDAs, engineering service agreements, term sheets, licensing agreements, offtake agreements, strategic supply agreements, strategic partnership agreements and project-level commercial contracts

•       Take and defend clear positions on representations and warranties, indemnification, liability caps, IP ownership & governance, and dispute resolution - and know when to hold firm and when to negotiate

•       Develop and maintain standard form agreements and negotiation playbooks that keep Mantel's contracting process efficient and consistent

•       Maintain a clean contracts repository and ensure Mantel's obligations, rights, and key dates are tracked and enforced

•       Develop and manage external counsel relationships where specialized expertise is needed, keeping scope and cost tight

2. Commercial Strategy & Deal Structuring

•       Contribute to the strategic framing of commercial deals, not just the legal terms, but the structure, risk allocation, and commercial logic behind them

•       Help Mantel build scalable commercial structures as the company moves from demonstration to full deployment

•       Support due diligence processes for partnerships, project financing, and government grants

•       Serve as a trusted, accessible internal legal resource across the organization - fast, practical, and easy to work with

•       Work closely with the commercial, engineering, and finance teams to understand the deals Mantel is pursuing and the legal risks that actually matter

3. Term Sheets & Licensing

•       Draft and negotiate term sheets that set the right commercial and legal foundation before full agreements are executed

•       Own Mantel's licensing strategy from a contracts and legal perspective — understanding how IP rights, exclusivity provisions, grant-back clauses, and royalty structures interact with commercial objectives

•       Identify and push back on terms that create undue legal risk or limit Mantel's flexibility as the business scales

Who You Are:

Experience: 5+ years of transactional legal experience, in private practice or in-house at a technology, energy, or industrial company; startup or early-stage company experience or exposure is a strong asset

Education: Law degree required[AR1] [DR2] 

Put differently,

•        You trained as a lawyer and you're proud of it - you just don't want that to be called in at the end, you want to help run and shape the process from the get-go in partnership with your commercial colleagues

•       You've negotiated real commercial contracts and know how to take a position, defend it, and close

•       You give practical advice that moves deals forward and you are solution oriented - counterparties and colleagues alike know you're someone who gets things done

•       You have genuine curiosity about carbon capture, industrial decarbonization, and the commercial landscape Mantel is operating in

You're comfortable being Mantel's primary legal voice on commercial matters in a company where the legal function is still being built

What You'll Get:

•       Ownership of Mantel's commercial contracts function at a pivotal moment in the company's growth

•       A seat at the table for commercial strategy, not just legal review

•       Direct exposure to complex, novel deal structures across licensing, offtake, project development, and government contracting

•       A central role in building one of the most exciting carbon capture companies in the world
