Mechanical Engineer

About UsHomeostasis is pioneering advanced carbon conversion technology that transforms industrial CO2 emissions into valuable carbon materials. Using our innovative molten carbonate electrolysis process, we convert CO2 from atmospheric and emission sources into high-value products like graphite and carbon nanotubes. These materials have critical applications in energy storage, particularly as anode materials in Li-ion batteries. We're building strong relationships with leading industry partners to integrate our technology into their production processes, enabling a circular carbon economy while addressing domestic supply chain needs for advanced battery materials. The RoleWe're seeking a skilled Mechanical Engineer contractor to join our technical team for the full duration of our Block-4 prototype development. This is a full-time project commitment (40+ hours per week) to support the design and integration of mechanical systems across all subsystems, with particular focus on implementing environmental controls and autonomous/remote controlled mechanisms within a controlled, high temperature environment . You'll work closely with the Project Managing Mechanical Engineer, Fluids Engineer, and Electrical Engineer to create robust mechanical solutions for our carbon conversion reactor. This role requires expertise in structural design, thermal management, and mechanical integration, with an emphasis on creating scalable solutions for future pilot implementation. Key Responsibilities Collaborate with the Homeostasis tech team on the design and fabrication of the Block-4 electrochemical reactor for CO2 reduction to graphiteSupport mechanical design across Block-4 subsystems with focus on heat transfer, temperature control, structures, and high-temperature mechanismsLead the design of various subsystems and components of Block-4Develop and document CAD models, engineering drawings, and fabrication specificationsCollaborate with cross-functional engineering team to establish design requirements and ensure compatibility of all subsystemsEstablish and update mechanical design requirementsSupport prototype fabrication, assembly, testing, and iterationContribute to safety assessments, risk mitigation, and operational proceduresDesign for scalability for future pilot-scale generations of our tech Qualifications Required:BS or MS in Mechanical Engineering or related field3+ years of experience in mechanical design and prototype developmentProficiency with 3D CAD software and mechanical design toolsExperience with thermal management in high-temperature environmentsKnowledge of materials selection for specialized applicationsFamiliarity with fabrication processes and manufacturing constraintsStrong analytical and problem-solving skillsAbility to commit full-time (40+ hours/week) for the 6-month project durationLocated in or willing to relocate to Seattle/Tacoma areaAuthorization to work in the United StatesHighly Desired:Experience with heat transfer and temperature control at high temperaturesBackground in prototype development for chemical or electrochemical processesKnowledge of automation systems and mechanical integrationExperience with design for manufacturability and scalabilityTrack record of successful cross-functional collaboration in technical projectsExperience with design review processes and documentation standards The Ideal CandidateYou're a versatile, hands-on mechanical engineer who excels at integrating complex systems into functional prototypes.
