The Reliability Test Engineer will lead experiments for Linear Generators, collaborating with engineering disciplines, troubleshooting, analyzing data, and improving testing processes.

Lead root-cause analysis and redesign of mechanical components for durability and serviceability. Work hands-on at contract manufacturer to test, measure, rework, and validate improvements, integrate feedback into design and manufacturing processes, and support tooling and inspection efforts to improve product reliability.

Lead release management for embedded hardware and control software, define deployment strategies, manage versioning and rollback, communicate release impact to stakeholders, coordinate Field Operations during updates, and aggregate deployment feedback to improve reliability.

The Test Engineer will perform hands-on testing on Linear Generator units, develop testing processes, analyze data, and collaborate with engineering teams.

Lead the structural design and alignment for critical components of the Linear Generator, including testing and model validations while collaborating across teams.

Lead ~25 engineers and own 40-50% of a mechanical portfolio for a modular 250 kW-class linear generator. Drive risk mitigation, engineering review discipline (FMEA, DVP&R, tolerance analysis), supplier/manufacturing partnership, and development of future leaders to scale reliable power-generation hardware.

Lead the design of electrical enclosures and systems, manage engineers, and ensure project milestones through cross-functional collaboration.

Lead design and launch of electrical enclosures and cable systems for the Linear Generator. Define requirements, design and optimize hardware for manufacturability, coordinate testing and validation, collaborate with electrical, manufacturing, NPI, suppliers, and reliability teams, and iterate prototypes to meet performance, safety, cost, and production goals.

Design and optimize electrical enclosures and cables for linear generators. Lead projects from requirements through prototyping, testing, and production release. Collaborate cross-functionally with electrical, manufacturing, NPI, reliability, and suppliers to ensure manufacturability, safety, and system-level performance. Use CAD, simulation, and test feedback to iterate and deploy robust designs.

Serve as Mainspring's on-site quality liaison at a Monterrey contract manufacturer: enable inspection and test execution, approve FAI/FAT and control plans, coach local quality team, drive RCCA/CAPA, manage KPIs and document control, and partner on continual improvement to ensure volume production quality of linear generator assemblies.

Lead mechanical and electromechanical design for linear electromagnetic machines: optimize subsystems, perform failure analysis, validate via testing, collaborate with manufacturing and suppliers, and drive cost, performance, and reliability improvements for scalable linear generators.

Lead design, implementation, commissioning, and long-term support of industrial automation systems (PLCs, HMIs, robotics). Develop control software using Beckhoff/TwinCAT and IEC 61131-3, create electrical schematics, perform troubleshooting, continuous improvement, safety interlocks, and mentor junior staff while collaborating across mechanical, electrical, and software teams.

The Senior Sales Engineer develops system architecture and designs while providing technical expertise throughout the sales process, ensuring execution readiness and architectural integrity.

Lead and build tax compliance and risk processes: manage federal/state income tax filings, ASC 740 provisions, multi-state sales/use and property tax, support audits, oversee corporate insurance matters, implement tax automation, and partner cross-functionally to scale tax and risk management functions.

Responsible for the design and optimization of electrical enclosures and cables, guiding cross-functional teams and mentoring junior engineers for successful project execution.

Lead commercial origination by shepherding generation opportunities from early discussions through contracts and implementation. Serve as primary client contact, coordinate cross-functional teams, navigate RTO/ISO and interconnection processes, support PPA and commercial negotiations, and produce executive-level presentations.

Lead federal advocacy and policy strategy to advance Mainspring's linear generator technology. Engage the White House, DOE, Commerce, Congress, and committees; secure federal funding and public-private partnerships; manage external D.C. lobbying firms; build coalitions and industry partnerships; and support business development through U.S. government channels.

The Staff Cloud Platform Software Engineer will lead the development of the software ecosystem for monitoring and controlling distributed power generation systems, ensuring high reliability and performance.

The Senior EH&S Specialist develops and improves EHS programs, manages safety initiatives, analyzes safety data, and leads inspections to ensure compliance.
