Hire the Best Mechanical Engineers in California

Lead Mechanical Design Engineer specializing in taking complex hardware from early-stage concept to production. With 5+ years of experience spanning consumer products, medical devices, and aerospace systems, I bridge the gap between creative industrial design, rigorous engineering analysis, and retail-ready manufacturing. Experienced in technical system design, complex plastic injection-molded assemblies, and navigating demanding testing and regulatory frameworks—including environmental sealing, FMEA risk mitigation, and FDA 510(k) standards. As a technical lead, I thrive on guiding cross-functional teams, resolving critical-path hardware bottlenecks, and managing technical deliverables to bring premium, high-reliability products to market. I can provide STL's, fully editable & robust Solidworks models, technical drawings, and photo-realistic renderings.

Hello, Let me introduce myself. I am a physics engineer, materials science, and I have more than 15 years of experience as a design engineer. I have extensive experience in detailed design and modeling of tools and equipment, tolerance, and dimensional analysis. Very proficient in CAD, specifically in SolidWorks (owner of a Premium and Simulation Pro), Fusion 360 experience as well. Selection of materials, production processes, and suppliers. Calculation of cost and production time. I have experience designing finished products and tools/molds for the mold injection process, systems for high vacuum/ high pressure, inert, and dangerous gases, reverse engineering, CFD, and FEA analysis. Customer-oriented - I try to be neutral and objective, I fully listen to the person's comments and reflect on my work at the same time, with this fresh new perspective coming from this person's viewpoint. I respect they took the time to give me feedback and value their opinion. My job as a designer is to identify and find valuable solutions that will better serve customers. Sincerely, Vitaly

I am an experienced Mechanical and Plumbing Engineer with 13 years of expertise in engineering and project management. My journey includes significant roles in design and implementation, where I have successfully led projects from concept to completion. I specialize in optimizing engineering processes and ensuring projects are delivered on time and within budget. My technical acumen combines with a detail-oriented approach, allowing me to tackle complex challenges efficiently.

If you are looking for an engineer who can enhance your projects and drive innovation, I am ready to contribute and collaborate. Let's discuss how I can bring value to your team.

As a highly experienced Senior Mechanical Engineer with a track record spanning over 15 years, I have successfully navigated many different industrial domains. My mission is to leverage this wealth of engineering expertise to deliver premium consulting services, encompassing everything from design to creation of concept-to-manufacture schematic drawings, FEA analysis, and comprehensive Design for Manufacturability (DFM) insights. My proficiency extends to various SolidWorks certifications. With a proven ability to excel across a wide spectrum of industries, I invite potential clients to peruse my portfolio. I look forward to connecting with you and/or your company to understand your specific goals and collaborate on tailored solutions that will drive your success to new heights.

You have a hardware idea — or a prototype that needs to actually ship. That's where I come in. I'm a Top Rated+ mechanical and product design engineer with 9+ years turning concepts into production-ready hardware. I specialize in electronic enclosures, mechanical assemblies, and design-for-manufacturing — for funded startups, engineering teams, and hardware founders who can't afford to get this wrong. Currently embedded with an $8M Reg CF–backed hardware company, I bring the same rigor and speed you'd expect from an in-house senior engineer — without the overhead. What I deliver: — Custom enclosures & housings (PCB, IoT, consumer, industrial) — Mechanical assemblies: drivetrains, linkages, motion systems, actuators — Full DFM optimization for 3D printing, CNC, and injection molding — Investor-ready prototypes and production-ready CAD packages — 2D engineering drawings and tolerance specs I work directly with founders, CTOs, and engineering leads. I communicate clearly, move fast, and deliver files you can actually hand to a manufacturer. Tools: Fusion 360 (advanced) If you're building hardware and need it done right — let's talk.

I create and revise SolidWorks parts and assemblies, prepare manufacturing drawings, reconcile BOMs, and deliver STEP, STL, PDF, and native CAD files for suppliers and production teams. I also handle DFM reviews and prototype files. My background covers marine manufacturing, beverage equipment, VIP aircraft interiors, additive manufacturing, and production support. My recent work includes leading engineering for small-boat new builds, retrofits, repairs, and modernization. Upwork projects are handled directly by me. The work I take on here includes: • SolidWorks parts, assemblies, and revisions • Manufacturing drawings using GD&T and ASME Y14.5 practices • STEP, STL, PDF, and native SolidWorks deliverables • BOM cleanup and drawing-to-BOM reconciliation • Design reviews for 3D printing and injection molding • Work instructions, inspection records, and test documentation • Technical file review before supplier or production handoff Past Upwork projects include medical-device part models, CAD drafting, manufacturer STEP files, 3D printing, and parts-standards QA. Outside Upwork, I have supported controlled drawing packages, BOM changes, production issues, supplier coordination, and final acceptance work in marine, aerospace, and manufactured equipment environments. Send the model, drawing, markup, photos, BOM, or supplier comments you have. I will review the source files, point out missing or conflicting information, and confirm the scope before I start.
