Senior/Principal Mechanical Engineer
About The Position
At Torus, we're building the world's first mesh energy infrastructure, systems that protect communities, reduce costs, and strengthen the grid for decades to come. As a Senior or Principal Mechanical Engineer, you'll own the design, validation, and productization of the sub-systems that make resilient, scalable energy storage possible, whether that's battery-based, flywheel-based, or the integration points between them. This role sits at the intersection of deep technical ownership and systems thinking. You'll shape how hardware decisions ripple across the full product lifecycle, from early concept through high-volume manufacturing, balancing cost, complexity, reliability, and manufacturability as a unified problem. We value speed and quality equally; moving fast matters, but so does building it right the first time. If you thrive on hard problems, take full ownership from the first sketch to the final spec, and want your work to directly accelerate the energy transition, this role was built for you.
Requirements
- Bachelor's Degree in Mechanical Engineering or related field.
- 5+ years of hands-on experience in mechanical design, analysis, testing, and manufacturing, with demonstrated ownership and execution across the full product lifecycle.
- Proficient in SolidWorks CAD with strong command of part and assembly modeling, detailed drawings, and engineering documentation practices.
- Strong analytical foundation, comfortable sizing and validating designs through both first-principles calculations and Finite Element Analysis (FEA).
- Demonstrated experience in prototyping, testing, and design validation.
- Proven ability to take full ownership of complex technical challenges and system-level designs.
- Broad technical expertise spanning multiple mechanical engineering domains, with a passion for designing robust, reliable hardware.
- Proactive, action-oriented approach to problem-solving and continuous improvement.
Nice To Haves
- Experience leading hardware development at a technical or product level, setting direction, driving decisions, and bringing others along.
- Strong understanding and practical application of Geometric Dimensioning & Tolerancing (GD&T).
- Experience with Design of Experiments (DOE) and application of Statistical Process Control (SPC) in development and manufacturing environments.
Responsibilities
- Own hardware development and technical leadership through all stages: conceptualization, prototyping, testing, and production.
- Solve complex technical problems to meet product specifications, while balancing cost, complexity, and quality.
- Build, test, and analyze hardware systems using sensors, test equipment, and electromechanical components.
- Rapidly iterate on designs and analyses to guide product development direction.
- Apply Design for Manufacturing (DFM) principles, including poka-yoke techniques, to reduce part count, process complexity, and improve reliability.
- Collaborate closely with cross-functional teams and external engineering partners to drive design decisions and execution.
- Ensure designs comply with applicable codes, industry standards, and safety requirements.
Benefits
- Employee Rewards Package including equity
- 401(k) Retirement Savings Plan
