Job Description

Commonwealth Fusion Systems (CFS) has the fastest, lowest cost path to commercial fusion energy.


CFS collaborates with MIT to leverage decades of research combined with groundbreaking new high-temperature superconducting (HTS) magnet technology. HTS magnets will enable compact fusion power plants that can be constructed faster and at lower cost. Our mission is to deploy these power plants to meet global decarbonization goals as fast as possible. To that end, CFS has assembled a team of leaders in tough tech, fusion science, and manufacturing with a track record of rapid execution. Supported by the world’s leading investors, CFS is uniquely positioned to deliver limitless, clean, fusion power to combat climate change. To implement this plan, we are looking to add dedicated people to the team who treat people well, improve our work by adding multifaceted perspectives and new ways of solving problems, have achieved outstanding results through a range of pursuits, and have skills and experience related to this role.


We are actively seeking a dynamic finance leader to join our team as the Corporate Controller. This pivotal role involves comprehensive oversight of the company’s accounting functions, including all financial transaction recording and reporting, the company’s strong controls environment, financial operations, and, overall, contributing to process improvement across the company.


In addition, the successful candidate will join the company’s leadership team, reporting to the Chief Financial Officer, on our journey from the current single location, pre-revenue stage, to an operating company with a broad range of commercial and development activities, and therefore will be looked to for a wide range of financial, process and business insight.


A strong accounting background, including a CPA certification and experience as the corporate functional leader of a dynamic, growing company is valued. Additionally, although we do not presently have plans to go public, we do expect to be doing periodic financings, so experience with Sarbanes-Oxley (SOX) compliance, a successful track record with a public accounting firm and experience operating a company with SEC reporting requirements is also important.
