We arethe 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.\nTorus 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.\nAt 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.\nAbout the Role\nAt 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.\nThis 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.\nIf 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.\nWho You Are\nYou 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.\nYou 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.\nYou 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.\nYou 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.\nYou build trust through transparency. You give feedback directly and privately when it matters, celebrate teammates openly, and assume positive intent when things get hard.\nYou 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.\nKey Responsibilities\nOwn hardware development and technical leadership through all stages: conceptualization, prototyping, testing, and production.\nSolve complex technical problems to meet product specifications, while balancing cost, complexity, and quality.\nBuild, test, and analyze hardware systems using sensors, test equipment, and electromechanical components.\nRapidly iterate on designs and analyses to guide product development direction.\nApply Design for Manufacturing (DFM) principles, including poka-yoke techniques, to reduce part count, process complexity, and improve reliability.\nCollaborate closely with cross-functional teams and external engineering partners to drive design decisions and execution.\nEnsure designs comply with applicable codes, industry standards, and safety requirements.\nRequired Experience\nBachelor's Degree in Mechanical Engineering or related field.\n5+ years of hands-on experience in mechanical design, analysis, testing, and manufacturing, with demonstrated ownership and execution across the full product lifecycle.\nProficient in SolidWorks CAD with strong command of part and assembly modeling, detailed drawings, and engineering documentation practices.\nStrong analytical foundation, comfortable sizing and validating designs through both first-principles calculations and Finite Element Analysis (FEA).\nDemonstrated experience in prototyping, testing, and design validation.\nProven ability to take full ownership of complex technical challenges and system-level designs.\nBroad technical expertise spanning multiple mechanical engineering domains, with a passion for designing robust, reliable hardware.\nProactive, action-oriented approach to problem-solving and continuous improvement.\nPreferred Experience\nExperience leading hardware development at a technical or product level, setting direction, driving decisions, and bringing others along.\nStrong understanding and practical application of Geometric Dimensioning & Tolerancing (GD&T).\nExperience with Design of Experiments (DOE) and application of Statistical Process Control (SPC) in development and manufacturing environments.\nAdditional Details\nBackground Check All candidates are subject to a background check.\nLocation + Travel The role is based in our GigaOne Warehouse (air-conditioned) with some remote work, as needed. May require occasional onsite work at our Headquarters in South Salt Lake and/or Springville R&D warehouse (air-conditioned and non air-conditioned).\nSchedule Full-Time, Salaried\nCompensation $100,000-145,000 (Note: We have the flexibility to hire at different levels, which may impact the corresponding pay range.)\nWork Authorization Applicants must already have the legal authorization to work in the US without requiring any employer sponsorship.\nPhysical Requirements\nMust have the ability to safely lift and move objects weighing up to 50 lbs. \nMust be capable of standing, bending, and executing repetitive tasks for prolonged periods of time.\nAbility to read, identify, observe and recognize details, color-coding and fine print at close range on associated engineering drawings.\nAbility 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. \nAbility to observe, detect and respond to audible and visual machine malfunction warnings.\nAbility to communicate information so others can understand. Must be able to exchange accurate information in these situations.\nMust report to work reliably and with the ability to use full and unimpaired skills and judgment to safely execute your job.\nProficiency in reading, writing, and speaking English required.\nOur Perks & Benefits\nBenefits eligibility is based on employment status.\nFinancial\nEmployee Rewards Package including equity\n401(k) Retirement Savings Plan\nTorus paid life and AD&D Insurance with options to purchase additional coverage\nVoluntary short- and long-term disability insurance\nHealth & Wellness\nHealth Benefits Package: Choice between traditional PPO or HSA-eligible medical plans with Torus covering 50% of medical premiums; Dental insurance; and Vision insurance\nPlan participants have access to telehealth services, mental health support and coaching, and exclusive discounts on brands, dining, entertainment, and more.\nTime Off\nUnlimited discretionary PTO or 10 days annual PTO\n10 paid company holidays\nWaiting period-free 100% paid parental leave\nCulture & Community\nRegular company-wide offsites to showcase our progress and learnings. A time to step back, think strategically, and work on the business together.\nTeam members receive Torus branded gear\nPeer Recognition Program\nFully stocked break rooms with free snacks and drinks.
