Principal Mechanical Engineer

Role Overview

• Own mechanical product definition from early concept through production
• Define and prioritize requirements, performance specifications, system architecture, and key trade‑off decisions based on customer needs, costs, schedules, and manufacturability
• Evaluate product scope, feature set, and technical direction
• Perform hands‑on design, analysis, and troubleshooting of complex systems to include mechanical, electrical, and firmware
• Integrate products with other devices and systems to ensure system‑level compatibility and performance
• Direct test engineers and help define test strategies, fixtures, validation plans, and acceptance criteria; conduct and review laboratory and field testing
• Analyze data to drive design improvements and corrective actions
• Create and maintain Bills of Materials (BOMs)
• Work with Contract Manufacturers and ODMs to ensure alignment between design intent, cost targets, and supply chain constraints, resolve issues and ensure production readiness, quality, and manufacturability
• Apply structured design and quality tools (RCCA, FMEA, design reviews) to manage risk and prevent failures
• Support patent generation and prepare technical documentation for novel product concepts

Requirements

• Bachelor’s degree in Mechanical Engineering or related field; master’s degree preferred
• 7+ years of progressive mechanical / electro-mechanical product development experience
• Demonstrated experience leading mechanical products from concept through production
• Strong mechanical fundamentals with the ability to independently solve complex problems
• Experience making product‑level tradeoffs and prioritizing requirements in ambiguous environments
• Hands‑on experience with CAD (SolidWorks preferred), BOM management, and design documentation
• Experienced working with external vendors and contract manufacturers, including ODMs / overseas suppliers
• Familiarity with structured problem‑solving and risk tools (RCCA, FMEA, fault trees, fishbone)
• Experience designing or overseeing test fixtures, validation systems, and verification plans
• Knowledge of thermodynamics, heat transfer, and fluid systems
• Vacuum pump or fluid‑handling system experience preferred, not required
• Ability to travel up to 20% domestically and internationally (typically ~1 overseas trip/year)

Benefits

• Matching 401k up to 4% with immediate vesting.
• Excellent medical benefits including an HSA plan and monthly contributions.
