Mechanical Engineer II - Stack Engineering
The Role
The Mechanical Engineer II - Stack Engineering will support the design, prototyping, and testing of stack hardware for Travertine's electrochemical systems. This role will work closely with cross-functional teams to advance mechanical design from early-stage concept and rapid prototyping through to functional mass-produced parts and assemblies. The engineer will also contribute directly to the design, fabrication and operation of electrochemical test systems.
This role will contribute to the development of features critical to electrochemical performance. These features include components for optimizing flow distribution and mass transport, thermal management, durable sealing methods and reduction of ohmic and faradaic losses. Our process is well suited to scale rapidly as it combines three industrialized unit operations in a novel way: salt-splitting electrolysis, hydrometallurgy, and caustic direct air capture of CO2. This is the perfect opportunity for an ambitious and creative mechanical engineer to contribute to complex development efforts and rapidly take a technology from pilot to full-scale.
Critical to this role, will be working closely with our Electrochemical R&D and Process Engineering teams to identify areas for mechanical and electrochemical design improvement, develop prototypes, and fine-tune validation procedures to translate those results into engineering design. This role will also interface with external consultants, manufacturers and integrators to bring concepts and prototypes toward commercial success.
Key Responsibilities
- Design & Prototyping: Create detailed CAD models, drawings, and physical prototypes for electrochemical cells, test stands, and mechanical fixtures.
- Testing & Validation: Design and execute experimental testing to characterize hardware performance, resistance, pressure limits, and fluid/thermal properties.
- Data Acquisition & Automation: Implement instrumentation, sensors, controls, and data acquisition tools to validate system performance.
- Cross-Functional Collaboration: Work with R&D, process development, and senior engineers to translate technical requirements into robust hardware solutions.
- Fabrication & Sourcing: Interface with local machine shops, vendors, and internal fabrication tools to build custom components and assemblies.
- Design for Manufacturability: Optimize the design of parts and assemblies to reduce cost and improve reliability, manufacturing cycle time and yield.
Qualifications
- Bachelor's degree or greater in Mechanical Engineering.
- Educational or industry background in electrochemistry preferred.
- 2+ years of hands-on mechanical design and rapid prototyping experience in hardware, startup, or industrial environments.
- Proficiency in 3D CAD modeling, drafting, and mechanical design principles.
- Experience with machine shop operations (milling, turning, welding) and safe chemical/laboratory practices.
Compensation & Benefits
- Competitive pay
- Stock options
- Health, Dental, Vision, Life Insurance
- 401k with 100% match up to 3% of salary
- Flexible time off policy
This role is onsite and based in our Boulder, CO headquarters.
Salary range is highly dependent on skill set and experience $100,000-$120,000 per yr.
