- As a Senior Mechanical Engineer within the Mechanical Department, you will own the design and execution of complex mechanical subsystems that directly influence the economics, reliability, and scalability of our core technology
- This role spans early-stage R&D; through NPI and site-scale deployment, requiring strong engineering fundamentals, sound judgment, and a bias toward practical, manufacturable solutions
- You will be expected to challenge assumptions, rigorously evaluate tradeoffs, and push the boundaries of design and manufacturing while maintaining a clear focus on cost, reliability, and long-term operability
- This is a high-ownership individual contributor role with significant technical leadership and cross-functional influence
- Own end-to-end design of complex mechanical subsystems, from requirements definition and concept architecture through validation, production ramp, and deployment
- Drive subsystem performance across cost, reliability, manufacturability, and serviceability, with direct impact on $/ton CO₂ economics
- Design low and high-volume components using a variety of manufacturing processes, including sheet metal stamping, casting, roll forming, and extrusions
- Lead design trade studies using first-principles analysis, data-driven methods, and sound engineering judgment
- Design and develop product-level test equipment, fixtures, and validation strategies to support Design for Reliability (DfR), including accelerated life testing, stress testing, and failure-mode–driven validation to ensure robust subsystem and system performance over the intended service life
- Partner closely with suppliers, equipment operators, manufacturing, and supply chain teams to ensure designs are robust, scalable, and production-ready
- Generate and review detailed 2D drawings with proper GD&T;, aligned with production and inspection standards




- Support rapid prototyping and iterative development cycles while maintaining a clear path to NPI rigor
- Act as a technical leader within the team by mentoring peers, driving best practices, and raising the bar for engineering quality
- Excellent engineering fundamentals, with the ability to apply first principles, modeling, and data to real-world design decisions
- Demonstrated ability to lead technically complex projects or subsystems with minimal supervision
- Strong sense of ownership, accountability, and follow-through—delivering high-quality work on schedule
- Experience with engineering analyses such as reliability modeling, tolerance analysis, FEA, fatigue analysis, and root cause analysis
- 5+ years of experience designing and delivering products through the full lifecycle, from concept to production
- Strong passion for product design and solving complex engineering problems with simple, robust solutions
- Proven track record of working cross-functionally to balance competing requirements and constraints
- Experience applying Design for Reliability (DfR) principles, including failure mode identification, reliability modeling, accelerated life and stress testing, and translating test results into durable design improvements
- Experience producing clear, accurate drawings and specifications suitable for manufacturing and inspection
- You don’t have to have every listed requirement and skill to be a great fit. If you are passionate about this opportunity and think you have the skills to succeed, please apply!
- Hands-on experience designing sheet metal (stamping, press brake), weldments, and plastic parts (e.g., injection molding, thermoforming)
- Background in random vibration and fatigue testing, metallurgy, material and test standards
- Experience managing development in a product lifecycle management system (PLM)
- Comfort operating in both quick-paced R&D; environments and the structured rigor of NPI execution
- Experience using NX in a production or industrial context
