At Forge, we believe nuclear fission is the key to solving both at once. Today Forge is developing the technology to rapidly scale the deployment of nuclear fission. ### Sr. Mechanical Engineer, Components As a components engineer at Forge, you'll be responsible for some of the most critical pieces of Ember, our 25 MWe nuclear reactor. Components engineers at Forge serve as hardware experts across fluid and electromechanical devices that drive the critical capabilities of our system - from the valves that control steam flow to the turbine to the heat exchangers that transfer thermal energy from the primary to secondary loop. In this role, you will have the opportunity to utilize your knowledge, experience, and creativity to develop novel solutions at the cutting edge of nuclear energy. Sr. Components Engineers will own the most critical component developments while setting the technical bar for the components engineering team. ### Responsibilities Develop state-of-the-art, manufacturable flow control devices (valves, regulators, solenoids), mechanisms (control-rod drive mechanisms), and heat exchangers through end-to-end ownership (design, analysis, production layout, assembly, environmental testing, and reactor integration). Question requirements, delete parts and processes, simplify/optimize, accelerate, and automate component deliveries Validate reliability of hardware and designs with rigorous testing: thermal cycling, pressure cycling, shock, vibration, and radiation embrittlement. Design experiments to ground analysis, develop fixturing, and create technical reports based on results Collaborate with peers from different systems to develop designs that balance cost, efficiency, and deployment logistics Support the assembly of your hardware in the factory, witness your designs being brought to life daily, and watch them power an abundant, clean future Provide training and mentorship to junior components engineers, setting the standard for technical rigor across the team ### Basic Qualifications Bachelor's degree in mechanical engineering or a related technical discipline 5+ years of mechanical design/hands-on manufacturing experience ### Preferred Skills and Experience Strong interpersonal and collaborative skills, enthusiasm for problem solving, and desire to enable abundant clean energy 5+ years of experience designing and analyzing mechanical systems via professional work experience, project/research-based student experience, or a combination of both Experience acting as a technical lead — scoping work, reviewing designs and processes, and guiding other engineers to successful outcomes Ability to perform trade studies and make clear recommendations using first principles and engineering fundamentals even with partial information Experience working at a nimble engineering organization or in a highly technical position that required a scrappy, entrepreneurial manner to accomplish tasks with tight time or budget constraints Hands-on experience with fluid, gas, or thermal systems Experience using test instrumentation and control components (e.g. pressure transducers, thermocouples, resistance temperature detectors, relays, solenoid valves, etc.) Knowledge of electro-mechanical devices, actuators, pumps, valves, regulators, or other fluid and position control devices ### Additional Requirements Position will be based in the South Bay area of Los Angeles County and will require relocation if not already local. The position will be full-time in the office. Ability to work extended hours and weekends as necessary Ability to travel to reactor construction sites in other states as necessary ### Compensation and Benefits Pay range: Senior: $140,000.00 - $190,000.00/per year + equity Your actual level and base salary will be determined on a case-by-case basis and may vary based on the following considerations: job-related knowledge and skills, education, and experience. --- Data: alder (https://alderhq.app).
