Senior Mechanical Design Engineer

Ecotal; Irvine (CA); On-site; USD 120,000 - 160,000; Full time

Job summary

Ecotal is seeking a Senior Mechanical Design Engineer to own design, development, build and testing of a first-of-its-kind mechanical platform for energy technology.

You will guide concepts through to production, coordinating with suppliers and fabricators, performing analyses, CAD work and physical testing to ensure robust hardware.

Qualifications

• 7+ years of mechanical design experience in complex, integrated hardware.
• Strong fundamentals and experience taking hardware from concept through build, test and production.
• Hands-on experience with CAD, GD&T, DFMA and supplier engagement.

Responsibilities

• Take complex mechanical hardware from requirements and concept through detailed design, prototypes, testing and commercialization.
• Work across analysis, CAD, suppliers and physical hardware to make practical design decisions.
• Engage with suppliers and fabricators; iterate designs based on testing and performance.

Job description

We are supporting a well-funded energy technology company developing a fundamentally new approach to utility-scale power generation.

The company is building a first-of-its-kind mechanical platform from the ground up and is looking for a Senior Mechanical Design Engineer to take significant ownership across the design, development, build and testing of the system.

This is a hands-on role for an engineer who enjoys understanding the whole machine, rather than owning one narrow component.

The Role

You will take complex mechanical hardware from requirements and concept through detailed design, suppliers, prototype builds, physical testing and ultimately commercialization.

The scope will include:

• Complex, high-part-count mechanical and structural assemblies
• Metallic structures, castings, weldments, machined and sheet-metal components
• Composites, bonded joints, fasteners and mechanical interfaces
• Structural/stress analysis, load paths, stiffness, fatigue and durability
• Material and manufacturing-process selection
• CAD, drawings, GD&T and DFMA
• Supplier and fabricator engagement
• Prototype builds, physical testing, failure analysis and design iteration
• Engineering trade-offs across performance, weight, cost, reliability and manufacturability

What We're Looking For

• We’re looking for approximately 7+ years of mechanical design experience, ideally with complex, highly integrated hardware.
• You’ll have strong mechanical design fundamentals and experience taking hardware from concept through build, test and production. You should be comfortable moving between analysis, CAD, suppliers and physical hardware, with the engineering judgement to make practical design decisions.
• Relevant backgrounds could include automotive/EV, aerospace, motorsport, industrial machinery, automation, energy hardware, marine or other complex mechanical systems.
• Experience with Formula SAE, Baja SAE, racing, competitive sailing or similarly hands‑on engineering environments is also highly relevant.
• This is an opportunity to join a small, highly technical team where you’ll have significant influence over the wider mechanical system and see your engineering decisions become real hardware.
