Job Description

Cyclic Materials is building a resilient circular supply chain for rare earth elements and other critical materials. Through our fully integrated proprietary technology platform, we recover rare earths from end-of-life products and transform them into high-purity materials used to produce new permanent magnets. These magnets are critical to the up-to-date economy, underpinning AI, automotive, e-mobility, electronics, semiconductor, energy, defense, and other advanced manufacturing sectors.

Founded in 2021, Cyclic Materials has rapidly become a category leader in rare earth recovery, achieving commercial operations in less than five years. We currently operate facilities in Ontario and Arizona, with further expansion underway in South Carolina.

Backed by investment accounts advised by T. Rowe Price Associates, Inc., alongside strategic investors including Microsoft, Amazon, Hitachi Ventures, BMW i Ventures, Jaguar Land Rover's InMotion fund, Energy Impact Partners, ArcTern Ventures, and Fifth Wall, we are scaling quickly and building the industrial backbone required to meet growing global demand for a secure and sustainable supply of rare earths.

We have established an extensive and growing network of commercial partnerships with global industry leaders such as Solvay, Vattenfall, Lime, and VACUUMSCHMELZE, enabling the rapid deployment of recycled rare earth materials into real-world supply chains.

Joining Cyclic Materials means tackling complex and exciting challenges at scale alongside a team committed to strong execution and measurable impact. If you are motivated by building critical infrastructure and advancing the circular economy,



join us and help accelerate the growth of rare earth recycling.

Position Overview

The Mechanical Engineering SME operates within an Owner's Team model as the internal Subject Matter Expert responsible for defining mechanical engineering requirements and overseeing external design partners.

This role focuses on reviewing and validating externally developed designs to ensure they are fit for purpose, meet specifications, and align with sound engineering principles, while liaising with and holding external teams accountable for quality and performance. The Lead provides final technical review and sign-off, bringing deep expertise and experience to the role.

This role acts as a senior member of the owner's engineering team and is accountable for ensuring that mechanical design solutions are safe, reliable, operable, maintainable, and aligned with project objectives. The Lead Mechanical Engineer will work closely with internal project engineers and external engineering, EPCM, and equipment vendors to develop fit-for-purpose mechanical designs that support project progression through FEL-2, FEL-3, and FEL-4 detailed engineering, construction, commissioning, and handover.

The successful candidate will provide technical leadership across mechanical systems including rotating equipment, static equipment, piping, material handling systems, utilities,



package equipment, and plant infrastructure, while supporting engineering governance, design reviews, risk management, and value improvement initiatives. This may also include overseeing and/or participating in all HAZOPS and subject matter regulatory reviews.

Key Responsibilities

Lead mechanical engineering activities for capital projects through FEL-2, FEL-3, and some FEL-4 execution planning. Serve as the mechanical engineering lead within Cyclic's owner's team, ensuring that internal and external engineering deliverables meet project requirements, technical standards, and stage-gate expectations. Manage and review the work of external engineering consultants, EP, EPC, EPCM and similar build partners, equipment suppliers, and specialist contractors for mechanical scope.

Develop and maintain mechanical design criteria, engineering specifications, equipment standards, and discipline deliverables to support project development and execution. Provide technical leadership for mechanical systems including rotating equipment, tanks, vessels, heat exchangers, pumps, piping systems, material handling systems, utility systems, and package equipment.

Review and approve mechanical engineering deliverables such as equipment datasheets, equipment lists, piping and instrumentation diagrams, layouts, mechanical design packages, technical bid evaluations, and vendor documents. Support development of plant layouts and equipment arrangements with a focus on constructability, maintainability, operability, accessibility, and safety. Participate in and lead discipline input into design reviews, HAZOPs, mod
