Senior/Principal Mechanical Engineer

About the role

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.

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.

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.
• 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.

Qualifications

• Must have the ability to safely lift and move objects weighing up to 50 lbs.
• Must be capable of standing, bending, and executing repetitive tasks for prolonged periods of time.
• Ability to read, identify, observe and recognize details, color-coding and fine print at close range on associated engineering drawings.
• Ability to don personal protective equipment to include, but not limited to, respiratory protective equipment with proper seal, coveralls, ear protection, gloves, eye protection & safety helmet.
• Ability to observe, detect and respond to audible and visual machine malfunction warnings.
• Ability to communicate information so others can understand. Must be able to exchange accurate information in these situations.
• Must report to work reliably and with the ability to use full and unimpaired skills and judgment to safely execute your job.
• Proficiency in reading, writing, and speaking English required.

Skills

• Hands-on experience in mechanical design, analysis, testing, and manufacturing.
• Strong analytical foundation and proficiency in SolidWorks CAD.
• Experience with Design for Manufacturing (DFM) principles and Geometric Dimensioning & Tolerancing (GD&T).

Benefits

• Employee Rewards Package including equity.
• 401(k) Retirement Savings Plan.
• Torus paid life and AD&D Insurance with options to purchase additional coverage.
• Voluntary short- and long-term disability insurance.
• Health Benefits Package: Choice between traditional PPO or HSA-eligible medical plans with Torus covering 50% of medical premiums; Dental insurance; and Vision insurance.
• Telehealth services, mental health support and coaching, and exclusive discounts on brands, dining, entertainment, and more.
• Unlimited discretionary PTO or 10 days annual PTO.
• 10 paid company holidays.
• Waiting period-free 100% paid parental leave.
