Senior/Principal Mechanical Engineer
About The Position
At Torus, the Senior or Principal Mechanical Engineer owns the design, validation, and productization of mechanical subsystems for resilient, scalable energy storage, including battery-based and flywheel-based systems and their integration points. The role combines deep technical ownership with systems thinking, shaping hardware decisions across the product lifecycle from early concept through high-volume manufacturing while balancing cost, complexity, reliability, and manufacturability. The engineer leads hardware development from initial concepts through prototyping, testing, and production; solves complex technical problems; and iterates designs and analyses to guide product direction. The role works closely with cross-functional teams and external engineering partners, applies design-for-manufacturing practices, and ensures designs meet applicable codes, standards, and safety requirements. The position is based at Torus's air-conditioned GigaOne Warehouse, with some remote work as needed and possible occasional onsite work at the South Salt Lake headquarters or Springville R&D warehouse, which may be air-conditioned or non-air-conditioned. The role is full-time and salaried.
Requirements
- Bachelor's degree in Mechanical Engineering or a related field.
- At least 5 years of hands-on experience in mechanical design, analysis, testing, and manufacturing, with demonstrated ownership and execution across the full product lifecycle.
- Proficiency in SolidWorks CAD, including part and assembly modeling, detailed drawings, and engineering documentation practices.
- Strong analytical foundation, including sizing and validating designs using first-principles calculations and Finite Element Analysis (FEA).
- Demonstrated experience in prototyping, testing, and design validation.
- Proven ability to own complex technical challenges and system-level designs.
- Broad technical expertise across multiple mechanical engineering domains and an interest in designing robust, reliable hardware.
- Proactive, action-oriented approach to problem-solving and continuous improvement.
- Legal authorization to work in the United States without employer sponsorship.
- Ability to safely lift and move objects weighing up to 50 pounds.
- Ability to stand, bend, and perform repetitive tasks for prolonged periods.
- Ability to read, identify, observe, and recognize details, color-coding, and fine print at close range on engineering drawings.
- Ability to wear required personal protective equipment, including respiratory protective equipment with proper seal, coveralls, ear protection, gloves, eye protection, and a safety helmet.
- Ability to observe, detect, and respond to audible and visual machine malfunction warnings.
- Ability to communicate information clearly and exchange accurate information.
- Ability to report to work reliably and use full, unimpaired skills and judgment to work safely.
- Proficiency in reading, writing, and speaking English.
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 applying Statistical Process Control (SPC) in development and manufacturing environments.
Responsibilities
- Own hardware development and provide technical leadership through 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 and process complexity and improve reliability.
- Collaborate 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.
- At senior or principal level, lead technical direction and mentor less experienced engineers.
