Engineering Technician
Company Overview
Lydian is developing the lowest cost sustainable fuels from waste CO2, water, and renewable electricity to decarbonize the aviation industry. Our breakthrough technology replaces oil and gas refining with fully electrified, modular, and flexible reactor systems that produce fuel with 95% lower emissions than traditional jet fuel.
Since our founding in 2021, Lydian has achieved key milestones in record time, including the production of our first liquid fuel from our pilot system. Lydian is backed by the world's top energy transition investors including Congruent Ventures, Galvanize Climate Solutions, Union Square Ventures, Voyager Ventures, Grok Ventures, and Overture. We have also earned support from the US Department of Energy, the Defense Advanced Research Projects Agency (DARPA), and have been recognized by Forbes 30u30 and by Silicon Valley Bank's 50 by 2050 List which recognizes the top fifty energy transition companies based on potential impact and scale.
Position Overview
Lydian is looking for an Engineering Technician to support its 25,000 sq ft lab and pilot facility in Charlestown, MA. This role is highly hands-on and central to keeping our equipment reliable and our experimental and production workflows running smoothly. You will build, maintain, disassemble and rebuild custom mechanical systems, troubleshoot equipment issues, and support the development of standard operating procedures (SOPs) for our specialized aviation fuel production and testing equipment. The ideal candidate will have strong experience with process piping and play a pivotal role providing feedback to engineers on the layout and design of complex P&IDs.
This role is day-shift (non-rotating) but supports commissioning, outages, and occasional extended hours during critical testing campaigns. This role requires onsite work in Charlestown, MA five days per week.
