Director of Mechanical Engineering

Job Description

Torus is headquartered in Utah and is expanding manufacturing at our 545,000-square-foot facility in Salt Lake City called GigaOne. We are the world's first mesh energy infrastructure, uniting communities through resilient, sustainable, and intelligent power. We design, engineer, manufacture, install, and support our systems end-to-end, standing behind them throughout their lifecycle. Torus systems help reduce costs, lower emissions, and protect facilities from outages, while strengthening the security and reliability of the broader utility grid. Torus is committed to American manufacturing, engineering excellence, and building energy systems that last.

Torus has raised over $267 million from investors like Magnetar, Mercado, ICONIQ and Origin Ventures. The investments are helping to accelerate deployment of modular power plants across utilities, data centers, and industrial sectors. This investor confidence reflects the strength of our team, technology as well as the scale of the problem we are solving.

At Torus, you will be part of something larger than a single product or technology. Your work will help build energy infrastructure that supports and strengthens our electrical grid, critical systems, industry, and communities for decades to come. We value accountability, collaboration, and clear thinking. We are looking for people who want to solve hard problems and build things that matter.

About The Role

We are looking for an experienced mechanical engineering leader who builds and scales a high-performing team while maintaining the technical credibility to guide hard decisions. As Director of Mechanical Engineering at Torus, you will own the technical direction and day-to-day execution of our mechanical engineering team, building a culture of engineering excellence, mentorship, and disciplined design practice across rotating machinery, structural systems, thermal management, and electromechanical integration.

This is a leadership role for someone who leads through technical judgment, not volume of individual output. You will stay close enough to the work to make sound calls and earn your engineers' respect, but your primary output is the team's capability, the quality bar, and engineering decisions that set that direction. You will also build and scale the team, set expectations, develop talent, and hold the bar on design quality across our flywheel and hybrid battery-flywheel energy storage systems.

Product requirements and roadmap priorities are set in partnership with product management. Within that direction, you own the mechanical engineering strategy: the technical and architecture direction for our mechanical systems, the team's capability roadmap, build-vs-buy decisions, and where we invest in deeper engineering expertise (such as rotor dynamics, structural analysis, or thermal management) as we scale. You translate product direction into a clear technical path, and you build the team, the structure, and the leaders to execute it.

You will report to the Head of Hardware Products and work cross-functionally with product management, manufacturing engineering, electrical engineering, and other key stakeholders to translate product direction into outstanding engineering outcomes and build the mechanical engineering capability Torus needs.

Who You Are

• A builder of engineers, not just products. Your most important output is the capability and confidence of the team around you. You invest in people the way you invest in designs: with rigor, attention, and a long view.
• Technically Credible. You stay close enough to the work to make sound calls and earn respect, but you lead through judgment and through people, not through personal output. Your engineers deserve a leader who understands what they are facing and can guide them without taking the work from them.
• A decisive, accountable leader. You make the call when the team needs one made, you are clear about who owns which decisions, and you do not let important decisions drift or default.
• An org-builder. As the team grows, you design the structure, level roles, and develop leads who can own subsystems independently. You scale the team, not just staff it.
• Mechanically intuitive. You can look at a rotor assembly, a thermal management layout, or a structural frame and immediately form a view on where the risk is. Your judgment is calibrated by real experience, not just titles.
• Calm under pressure. When a field failure comes in or a design review surfaces a serious problem, you are the steadying force in the room. You help the team think clearly, not react.
• Collaborative by default. You build trust with manufacturing, electrical, and firmware teams rather than optimizing in isolation. The best mechanical design is the one that works well for everyone who touches it.
• Direct and constructive. You give feedback clearly and privately. You hold the bar without making engineers feel small. You make the work better and the people stronger at the same time.
• Strategic when it counts, hands-on when it matters. You can zoom out to assess system-level risk and zoom back in to solve a hard mechanical problem alongside your team.

Responsibilities

People Leadership and Organizational Development (35%)

• The mechanical engineering team is growing and needs someone who invests in them daily with guidance, feedback, and genuine attention to their development
• Build a hiring plan tied to the product and capability roadmap, and partner with People Ops on leveling, compensation alignment, and workforce planning
• Develop managers and leads beneath you, not only individual contributors, building the bench that lets the organization scale beyond your direct reach
• Mentor engineers on mechanical design principles, analysis methods, manufacturing considerations, and engineering judgment through direct, daily engagement, not periodic check-ins
• Build and develop a high-performing mechanical engineering team across design, analysis, testing, and prototyping
