Mechanical Engineer

About Us We are Sila, a next-generation battery materials company. Our mission is to power the world’s transition to clean energy. To create this future, our team is building a better lithium-ion battery from the inside out today. We engineer and manufacture ground-breaking battery materials that significantly increase the energy density of batteries, while reducing their size and weight. The result? Smaller more powerful batteries that can unlock innovation in consumer devices and accelerate the mass adoption of electric cars to eliminate our dependence on fossil fuels. We're tackling one of the biggest challenges of our time every day, and together we're redefining what's possible. Are you ready to be a part of a team committed to changing the world?Who You Are Sila’s Equipment Engineering team in Alameda is seeking a highly motivated Mechanical Engineer to support the design of manufacturing-scale reactors, bridging the gap between R&D concepts and capital project execution. This role focuses on the development and design lifecycle for Sila’s best-in-class Silicon Carbon anode manufacturing technology. The ideal candidate combines strong analytical, problem-solving, and CAD skills with practical industrial experience and a commitment to safety and functional design. You will work both independently and cross-functionally to prioritize manufacturability, operability, reliability, and maintainability, enabling the standardized, scalable deployment of multiple reactor systems. This role offers opportunities to contribute to impactful projects, solve technical problems, and focus on solutions that bridge the gap between R&D and mass production. Responsibilities and Duties Execute mechanical design and development tasks for manufacturing-scale reactors, bridging R&D concepts to capital project execution. Perform high-fidelity thermal, fluid, and structural modeling (FEA) to validate reactor performance and drive design decisions. Develop detailed engineering packages, including equipment layouts, core IP drawings, equipment datasheets, and specifications. Drive safety and compliance by applying safety-by-design principles. Participate in the end-to-end project lifecycle, including vendor/fabricator coordination, factory acceptance testing (FAT), and field installation verification. Maintain accurate, controlled, and compliant engineering documentation throughout the project lifecycle. Actively seek and act on feedback, and provide constructive feedback to team members to improve work processes and systems. Knowledge and Skill Requirements Bachelor’s degree in Mechanical Engineering or a closely related field. 2+ years of mechanical design experience in industrial equipment environments with a focus on large-scale manufacturing. Proficiency in mechanical design software (e.g., SolidWorks, Fusion 360, AutoCAD) and development of P&IDs and fabrication packages. Strong technical expertise in reactor systems, thermal/fluid equipment, and fabrication methods. Familiarity with designing for high-temperature environments is highly desirable. Analytical proficiency in FEA analysis, thermal modeling, and precision tolerancing for reactor equipment.
