Job Description:
Senior Mechanical Engineer - Advanced Development Location:
On-site | Westlake Village, CA Salary Range: $125,000 - $155,000 A
rapidly growing technology company is seeking a Senior Mechanical
Engineer focused on advanced development and early-stage product
exploration. This role works upstream of formal product development
and focuses on evaluating emerging technologies, building
prototypes, and reducing technical risk before products move into
full-scale engineering programs. This position translates
high-level product concepts into functional mechanical systems and
experimental prototypes. The role combines hands-on design,
modeling, and testing to understand system behavior and inform
engineering decisions. You will collaborate closely with electrical
engineering, firmware, product management, and industrial design
teams to integrate mechanical solutions with emerging technologies
and system architectures. Responsibilities * Lead mechanical design
and development of early-stage concepts, prototypes, and
experimental systems for next-generation products * Translate
high-level product ideas and technology opportunities into
practical mechanical architectures and proof-of-concept designs *
Design, prototype, and test mechanical components and assemblies to
evaluate feasibility and performance * Conduct engineering analysis
including thermal performance, structural behavior, tolerance
stack-ups, and material evaluation * Create and maintain 3D CAD
models and prototype documentation to support experimentation and
concept evaluation * Design and build prototype hardware using
rapid fabrication methods such as additive manufacturing,
quick-turn machining, and soft tooling * Plan and execute
engineering experiments to validate design assumptions and
characterize system performance * Identify technical risks early in
the development process and develop strategies to mitigate those
risks * Collaborate with electrical engineering, firmware,
industrial design, and product teams to integrate mechanical
systems with electronics and sensing technologies * Evaluate new
materials, mechanisms, and manufacturing approaches to support
innovative product development * Document prototype results,
engineering insights, and design learnings for knowledge sharing
and future development programs * Support the transition of
validated concepts into full product development when technologies
mature * Contribute to internal engineering standards, design
practices, and technical knowledge within the organization
Requirements * 6-10 years of experience in mechanical engineering
within product development, R&D, or advanced concept
development environments * Strong experience designing mechanical
components using injection molded plastics, machined components,
and sheet metal * Demonstrated experience with rapid prototyping
and iterative engineering design * Proficiency with CAD tools,
preferably SolidWorks * Strong understanding of mechanical
fundamentals including materials, mechanisms, thermal management,
and structural behavior * Experience designing mechanical systems
that integrate with electronics or embedded systems is strongly
preferred * Ability to move quickly from concept to prototype and
iterate based on experimental results * Strong collaboration and
communication skills working across multidisciplinary engineering
teams * Experience using Microsoft tools such as Teams, Excel,
Visio, Project, and Word * Bachelor's degree in Mechanical
Engineering or related technical field
