Senior Mechanical Engineer, SPAN

• 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

Desirable

• 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
• SPAN's mechanical engineering capability spans San Francisco and India, with senior engineering talent across both locations contributing to a shared product portfolio
• In this role, you will own the SF-side prioritization, intake, and shared-tooling workstreams that connect the two offices — architecting the templates, conventions, workflows, and collaboration infrastructure that allow engineers in both locations to operate from a common foundation
• Your work directly enables the productivity of a broader engineering bench, including multiple senior and senior staff engineers in India whose effectiveness depends on a strong, well-organized partnership across time zones
• You will also work directly with our manufacturing partners across China and Southeast Asia, driving DFM reviews, resolving tooling and assembly questions, and shepherding pilot builds
• As an experienced practitioner, you will serve as a technical resource within the broader mechanical engineering function and contribute to the development of less experienced engineers across the team
• 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
• Perform tolerance analysis and contribute substantively to Failure Mode Effects Analysis (FMEA) processes
• 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
• Designing components for energy-efficient electrical ecosystems
• Designing new product concepts based on team inputs
• Driving engineering change requests and design updates
• Architecting an improved international 2D CAD collaboration workflow — file structure, drawing templates, intake process, status tracking — in partnership with engineering leadership across both offices
• Leading tooling reviews and pilot builds with international manufacturing partners
