Senior Mechanical Engineer

About the role

We are seeking a Senior Mechanical Engineer to join our Mechanical team in San Francisco. The role combines hands-on technical mechanical design work—3D CAD modeling and 2D drafting against ASME Y14.5-2018 standards—with ownership of the systems and workflows that allow our globally distributed mechanical engineering organization to operate as a single, cohesive team.

Responsibilities

• Create detailed 3D CAD models and 2D drawings, ensuring compliance with ASME Y14.5-2018 standards.
• Own the prioritization, intake, and sequencing of CAD work flowing between the San Francisco and India offices, serving as the SF-side point of contact for cross-office coordination.
• Architect and maintain the shared tools, templates, file management conventions, and collaboration workflows that allow our distributed mechanical engineering team to function as a single team across time zones.
• Drive DFM/DFA reviews with manufacturing vendors in China and Southeast Asia, resolve tooling and assembly issues, and protect design intent through production.
• Document design specifications and decisions clearly to maintain transparency across distributed teams.
• Apply product life cycle management tools and processes to manage revisions and maintain design integrity.
• Lead resolution of design issues, driving modifications that improve product performance.
• Define product performance requirements and test criteria for verification and validation.
• Drive product modules and components from concept to production volume while improving cost and quality.
• Serve as a technical resource and mentor for less experienced engineers, sharing standards, best practices, and operational knowledge across the team.

Qualifications

• Hold a BS in Mechanical Engineering or a related field; advanced degree a plus.
• Have a track record of identifying systemic issues and executing on resolutions to drive structural fixes that balanced competing inputs (design intent, manufacturability, cost, schedule) and outlasted any single project.
• Have 5+ years of experience in mechanical design with substantial application of ASME Y14.5-2018, or a Master's degree with 2+ years of equivalent experience.
• Demonstrate strong proficiency in SolidWorks; deep familiarity with other parametric modeling tools is a viable substitute.
• Have proven experience performing tolerance analysis and contributing to FMEA processes.
• Have hands-on experience using product life cycle management (PLM) tools to manage engineering projects through their lifecycle.
• Are proficient with the Google Workspace suite of tools (Sheets, Slides, Docs, Drive) for documentation, tracking, and cross-office collaboration.
• Have experience owning prioritization and sequencing of work across competing requests—a meaningful portion of this role is deciding what work goes where, and when.
• Communicate clearly and patiently in writing—much of the cross-office and vendor collaboration happens asynchronously over email, chat, and drawing markups.
• Are comfortable with occasional early-morning or evening calls to overlap with teams in India, China, and Southeast Asia.
• Have a track record of creating Standard Operating Procedures for product manufacturing or test execution.
• Have prior experience mentoring or serving as a technical resource for less experienced engineers.
• Have prior experience working with international design teams or offshore CAD/drafting resources.
• Have experience collaborating with contract manufacturers or tooling vendors in China, India, or Southeast Asia.

Bonus Qualifications

• A process- or tooling-improvement mindset—you've built templates, conventions, scripts, macros, or workflows that helped a team run more smoothly.
• Experience automating JIRA workflows—custom dashboards, automation rules, intake forms, or integrations that reduced manual coordination overhead.
• Familiarity with electrical systems and mechanical design integration.
• Experience demonstrating product performance through Engineering and Design Verification Test phases.
• Knowledge of industry standards and practices in manufacturing and product design.
• Cross-cultural communication experience or fluency in a second language relevant to our partner regions.
