Ingeniero Mecánico Senior/Principal

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.

Who You Are

• You seek context before conclusions. You approach complex problems and cross-functional work with curiosity first; asking questions, gathering perspective, and making sure you understand the full picture before drawing conclusions.
• You move with urgency and hold the line on quality. You hold speed and quality to the same standard. Both are requirements, not trade-offs. You've internalized "do it nice or do it twice" and it shows in how you work.
• You think in systems, not just components. Your design decisions account for manufacturing, serviceability, cost, and safety; not just what performs well on paper. You naturally zoom out to understand how your work connects to the whole.
• You communicate directly and without burying the lead. Whether you're presenting a trade study, flagging a risk, or pushing back on a spec, you lead with the answer and bring the data to back it up.
• You build trust through transparency. You give feedback directly and privately when it matters, celebrate teammates openly, and assume positive intent when things get hard.
• You take full ownership and bring others along. At a senior or principal level, you don't just execute; you lead technical direction, mentor less experienced engineers, and make the team around you faster and sharper.

Key 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.

Required Experience

• 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.

Preferred Experience

• 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.
