Mechanical Design Engineer

Helix Linear Technologies designs and manufactures high-precision motion control systems for industries where performance matters most, including aerospace, medical devices, defense, and advanced automation. Our components power mission-critical applications, where reliability and precision down to ±0.0001 inches make all the difference.

We are growing and investing in new products, advanced manufacturing capabilities, and the systems required to scale with discipline. At Helix, we put the customer first, operate with engineering integrity, and take extreme ownership of outcomes. We move with purposeful responsiveness and collaborate across teams to deliver solutions we’re proud to stand behind.

The Mechanical Design Engineer plays a critical role in designing, optimizing, and supporting Helix’s high-precision linear motion products. This senior-level role requires deep expertise in mechanical design, CNC manufacturability, tolerance analysis, and advanced Solid Works modeling.

You’ll work closely with Applications Engineering, Manufacturing, and Quality to create designs that meet demanding performance requirements while ensuring manufacturability s is a hands‑on, fast‑paced engineering role with significant impact on Helix’s advanced product roadmap.

• Design, configure, and optimize linear motion components and assemblies, ensuring performance, cost, and manufacturability requirements are met.
• Apply Design for Manufacturing (DFM) principles for CNC machining processes (milling, turning/lathe, wire EDM) and molded components.
• Create detailed models, drawings, and complex surfaces using Solid Works, including high‑precision geometries.
• Maintain product documentation, specifications, and drawing packages.

• Apply ASME Y14.5 GD&T correctly to communicate design intent and ensure inspectability.
• Select and structure datums, tolerance zones, and feature control frames appropriately.
• Communicate engineering intent clearly through design reviews, presentations, and documentation.

• Partner directly with CNC machinists, programmers, and Manufacturing Engineering to ensure designs are optimized for production.
• Develop fixtures, gauges, tooling, and equipment to improve manufacturability, quality, and throughput.
• Support prototype builds, root‑cause investigations, and process improvements.

• Specify heat treatment, finishes, and plating processes to AMS and industry standards (carburizing, nitriding, induction hardening, passivation, nickel plating, chrome plating, etc.).
• Interpret supplier certifications and collaborate with vendors to ensure material performance.

• Lead or support prototype builds, testing, and validation efforts.
• Conduct tolerance stack‑ups, failure analysis, and performance evaluations.
• Provide engineering support for production issues and corrective action activities.

• 98%+ drawing accuracy with correct GD&T, datums, and tolerance schemes requiring minimal to no rework from Manufacturing or Quality.
• Designs released to production within agreed timelines
  , with manufacturability issues reduced by at least 25% compared to legacy designs.
• DFM improvements implemented that reduce setup time, tooling complexity, or machining cycle time by 10–20% on assigned part families.
• Successful prototype builds with fewer than two engineering‑driven revisions needed to reach production readiness.
• Tooling/fixture designs delivered on time, supporting quality improvements or throughput gains on critical operations.
• Cross‑functional responsiveness, all engineering questions from Applications, Manufacturing, or Quality answered within 24 hours with clear, accurate guidance.

• An engineer with 8‑10+ years of experience in CNC‑driven product design.
• Highly collaborative with machinists, engineers, and cross‑functional teams.
• A detail‑oriented designer who values precision, manufacturability, and clarity.
• A problem‑solver with a sense of ownership and urgency.
• Someone who thrives in a high‑mix, low‑volume engineering environment.
