Senior Mechanical Engineer

Required Qualifications

You'd be a great fit for this role if you:

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

We'd love it if you also have:

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.
