Role Description
We're hiring a highly experienced Senior Staff Mechanical Design Engineer to lead the architecture and design of our thermal management system. This is a critical part of Form’s iron-air battery technology and it is vital to the system’s successful operation. In this role, you will be a technical cornerstone for the product architecture, detailed design stages, first-of-a-kind build activities, strategic vendor engagement, and design for cost.
You can expect to oversee the building and validation of complex system models, direct prototyping efforts across the company, drive us through a series of internal system prototypes, and act as a technical leader bridging cross-functional teams of chemical, electrical, and mechanical engineers. You will hold ultimate technical responsibility for design validation before the final manufacturing release.
If this sounds like the right position for you, apply now! This opportunity will help shape and scale our multi-day energy storage system, contributing to the growth of a fast-moving company with breakthrough technology and an incredible mission, contributing to a sustainable future!
Relocation assistance is available.
What you'll do:
- Lead the architecture, design, prototyping, and testing of the thermal management system, ensuring it meets and exceeds critical performance and strategic requirements
- Oversee the development of complex thermal flow system analytical models that drive fundamental design architecture decisions
- Direct the fabrication and testing strategies for first-of-a-kind prototypes to validate system design choices and mitigate technical risks at scale
- Drive the overarching strategy for high volume production, ensuring product designs are optimized for scale, cost, and reliability
- Lead complex system-level collaboration with the Electrical and Controls teams to optimize actuator and sensor integration
- Serve as a technical pillar within the organization, mentoring engineers across levels, elevating our mechanical engineering best practices, and championing safety, especially in the development of new laboratory processes
What you'll bring:
- Degree in Mechanical Engineering or related field; Bachelor's with 12+ years (or Master’s/PhD with 10+ years) of industry experience in mechanical design of equipment, liquid or gas handling systems
- Deep expertise in first-principles modeling and design, with a proven track record of optimizing complex designs for high-volume manufacturing and cost-down
- Extensive experience leading projects in a manufacturing environment and managing strategic relationships with manufacturing engineering teams
- Industry-leading experience optimizing mechanical design, thermodynamic systems, and complex interdisciplinary interfaces of fluid systems
- Sense of urgency and self-driven to hit difficult schedule targets
- Direct experience in product development within an early-stage environment ramping into production, with a history of driving technical strategy
