Qué Hacen
Commonwealth Fusion Systems (CFS) es una empresa privada pionera en energía de fusión que se especializa en fusión por confinamiento magnético basada en tokamak. Fundada como una escisión del Centro de Ciencia de Plasma y Fusión del MIT, CFS se centra en utilizar imanes superconductores de alta temperatura para lograr la producción comercial de energía neta (fuente: cfs.energy). La empresa ha logrado avances significativos en su tecnología, particularmente con el desarrollo de máquinas de fusión compactas que aprovechan décadas de ciencia tokamak. Sus proyectos insignia, SPARC y ARC, tienen como objetivo demostrar la ganancia de energía neta y la viabilidad comercial en los próximos años (fuente: cfs.energy).
Proyectos y Trayectoria
CFS está actualmente involucrada en varios proyectos innovadores, siendo el más notable la construcción de SPARC, que se convertirá en la primera máquina de fusión con energía neta del mundo. Ubicado en su Campus de Energía de Fusión en Devens, Massachusetts, SPARC tiene como objetivo demostrar la ganancia de energía neta para finales de la década de 2020 (fuente: cfs.energy). Además, CFS está planificando el proyecto ARC, una planta de energía tokamak de clase 400 MW diseñada para su implementación comercial a principios de la década de 2030. Estos proyectos están respaldados por avances tecnológicos significativos, incluyendo la exitosa prueba del módulo del imán solenoide central (CSMC) en noviembre de 2024, que confirmó la fabricabilidad de componentes críticos para SPARC (fuente: zoominfo.com).
Desarrollos Recientes
En los últimos dos años, CFS ha logrado un progreso notable, incluyendo la apertura de su Campus de Energía de Fusión en Devens el 10 de febrero de 2023, al que asistieron figuras destacadas como la Secretaria de Energía de EE. UU., Jennifer Granholm (fuente: cfs.energy). La empresa también ha asegurado financiamiento sustancial, recaudando $863 millones en agosto de 2024, sumándose a una ronda anterior de $1.8 mil millones en mayo de 2023, llevando el financiamiento total a más de $2 mil millones (fuente: wbjournal.com). Además, CFS anunció su primer sitio de planta de energía comercial en el condado de Chesterfield, Virginia, que será financiado y operado de manera independiente, con planes para la conexión a la red a principios de la década de 2030 (fuente: zoominfo.com).
Trabajar Allí
CFS ofrece una variedad de roles en diversas disciplinas, incluyendo ciencia de fusión, ingeniería, manufactura y ciencia de materiales. La mayoría de su fuerza laboral se encuentra en el campus de Devens, que ha crecido a más de 430 empleados (fuente: cfs.energy). La cultura de la empresa enfatiza la ejecución rápida y la transparencia, atrayendo talento de primer nivel de los sectores de fusión y manufactura. Los ejecutivos clave incluyen al cofundador y CEO Bob Mumgaard, junto con otros líderes en operaciones y ciencia, lo que indica una fuerte demanda de experiencia en tecnología avanzada y física (fuente: nasdaqprivatemarket.com). Si bien no se detallan beneficios específicos, la expansión y el respaldo de inversores sugieren paquetes competitivos para roles de alto calibre en un entorno impulsado por una misión (fuente: cfs.energy).

Commonwealth Fusion Systems is on a mission to deliver the urgent transition to fusion energy.
Combining decades of research, top talent, and new technologies, we're designing and building commercially viable fusion power plants. And we're working with policymakers and suppliers to build the energy industry of the future.
We're in the best position to make it happen. Since 2018, we've raised nearly $3 billion in capital, making us the largest and leading private fusion company in the world.
Now we're looking for more thinkers, doers, builders, and makers to join us. People who'll bring new perspectives, solve tough problems, and thrive as part of a team.
If that's you and this role fits, we want to hear from you.
Join the power movement as Lead Technician
As a Lead Technician on the Assembly Team at CFS, you will be responsible for overseeing and organizing the small technician teams to conduct all assembly activities to construct the SPARC Tokamak. This includes the handling, alignment, and mechanical integration of large electromagnetic coils, vacuum vessels, instrumentation systems, support structures, tooling and manipulation equipment, diagnostic systems, and superconducting cable bundles, all together into a tightly packed and highly integrated central device. You will use your extensive experience in building and handling large equipment, structures, or plant systems to facilitate the efficient and high-quality completion of SPARC. You will organize the day-to-day work orders of the day per the schedule, assign technicians to each set of work, adjust as needed from previous work or issues, give morning briefs and shift hand-off reports, and overall guide all activity in the assembly work areas. During this you will work directly and collaboratively with the engineers, the metrology group, the quality group, and many other team-members to ensure correct and precise completion of the components and identify and help resolve issues as they arise during the build process. You will work with other technicians and leads, working in a dynamic and flexible workplace that shifts focus and priority as needed to meet the schedule to complete our next-generation tokamak device.
This role is truly a once in a lifetime opportunity to use your hands-on assembly skills to accelerate the development of fusion energy by ensuring SPARC is built on time and to high quality!
