Senior Mechanical Engineer
Vital Lyfe
Mechanical Engineer
Vital Lyfe is a tech company redefining water autonomy through innovation, creating a new category of personal water making technology built to scale where infrastructure can't.
The mission is to own and build the core mechanical systems behind our product; pumps, valves, pressure vessels, and fluid-handling assemblies & take them from early concepts to production at scale. This is a hands on, high-ownership role for someone who wants to design, test, break, fix, and ship hardware.
What You'll Do
- Own major mechanical subsystems from concept through production ramp and launch.
- Design, prototype, and validate pumps, valves, pressure vessels, and related mechanical components.
- Drive system-level tradeoffs across performance, reliability, manufacturability, and cost.
- Build and run test plans to validate performance across real-world environments and edge cases.
- Work closely with electrical, firmware, industrial design, and manufacturing to turn ideas into shipped product.
- Help design and improve manufacturing processes and production equipment, including fixtures, tooling, and automation concepts.
- Iterate fast; identify problems, propose solutions, and implement changes without heavy process overhead.
- Support supplier selection, part qualification, and production ramp.
- Mentor junior engineers as the team grows (without becoming detached from hands-on work).
What We're Looking For
- Bachelor's degree in Mechanical Engineering or a related field.
- 5+ years of experience designing and shipping mechanical or electromechanical hardware.
- Strong CAD and FEA skills applied to real, production-intent designs.
- Experience taking products from prototype to manufacturing.
- Comfort working in ambiguity and making tradeoffs with incomplete information.
- Bias toward action, ownership, and practical engineering solutions.
Preferred Qualifications
- Experience with consumer hardware or high-volume manufacturing.
- Background in pumps, valves, pressure systems, or fluid mechanics.
- Exposure to automation, manufacturing process development, or production equipment.
- Startup or early-stage company experience.
Physical Job Requirements - Essential Functions
- Hands on work on development hardware.
- Long periods of standing, crouching, walking.
- Lifting up to 50 lbs.
Why Join Vital Lyfe?
- Work on high-impact problems with global relevance
- Help scale breakthrough technology in water security and climate resilience
- Early ownership in a high growth, engineering led startup
- Join a tight knit, mission driven team in a fast-paced environment
- Build long term career equity as we grow
Location Requirement: Ability to work 100% onsite in Torrance, CA (remote or hybrid work will not be considered)
