About The Position

Voya Energy is seeking a hands-on Staff Mechanical Engineer to own complex fluid systems and precision mechanisms for the development and scale-up of its metal-fueled generator technology. The role involves taking hardware—including components, subassemblies, and top-level assemblies—from conceptual design and CAD through development and production. The engineer will collaborate with teams working in power electronics, automation, data, and controls, and will own the design and integration of balance-of-plant systems, including fluid handling and thermal management, for electrochemical generators. The position is full-time and onsite in Hayward, California.

Requirements

Bachelor’s degree or higher in Mechanical Engineering or a related field.
At least 7 years of relevant industry experience in mechanical design and system development.
Experience designing and integrating balance-of-plant systems for electrochemical or similar process equipment, including fluid handling and thermal management.
Proficiency with 3D CAD software such as SolidWorks, NX, or Creo, including experience with large assemblies.
Demonstrated experience working in PDM and/or PLM environments.
Strong theoretical and practical background in fluid mechanics and heat transfer.
Hands-on experience specifying pumps, tanks, heat exchangers, and valves.
Experience with development testing, failure analysis, and debugging complex systems.
Deep understanding of manufacturing methods and Design for Manufacturability.
Comfort working in an accountable environment involving scope, schedule, budget, two-way feedback, and collaboration.
Familiarity with modern engineering collaboration tools such as Confluence, Slack, and Asana.
Demonstrated experience with FEA and/or CFD.
Demonstrated experience reading electrical schematics and drawings.
Ability to operate in a fast-paced startup environment.
Hands-on approach and bias toward action.

Nice To Haves

Demonstrated experience with installation, operation, and troubleshooting of equipment.

Responsibilities

Lead the design of precision mechanisms, material-conveyance systems, and fluid-handling systems using commercial and custom components alongside Voya Energy intellectual property.
Own mechanical design and integration of balance-of-plant systems, including fluid handling and thermal management for electrochemical generators.
Create and manage CAD models from individual components through large assemblies, covering static structure, material transfer, fluid systems, power electronics, instrumentation, and safety systems.
Apply fluid mechanics and heat-transfer knowledge to optimize system performance, including pump and blower selection, piping layout, heat-exchanger sizing, and pressure-drop analysis.
Use notebooks, spreadsheets, and computational modeling as needed.
Select and specify critical hardware such as pumps, blowers, heat exchangers, valves, and sensors; evaluate whether custom or commercially available components are appropriate.
Work directly with suppliers and fabricators from initial outreach through product delivery.
Integrate, install, and troubleshoot system instrumentation, including pressure transducers, flow meters, and thermocouples.
Create, revise, and manage the configuration of subsystem and top-level P&ID documentation using industry-standard formatting.
Collaborate with cross-functional teams to produce fabrication drawings and work instructions, applying GD&T (ASME Y14.5) and accounting for machining, welding, sheet-metal fabrication, installation, maintenance, and repair.
Develop test plans and conduct development testing to verify and validate assemblies.
Document assembly and operating procedures for new equipment and systems.
Support design reviews, test readiness, and test data reviews.
Drive documentation and configuration management.
