Precision Mechanical Design Engineer

About the role

Voxel Innovations is a small, mission-driven advanced manufacturing company solving difficult real-world engineering problems. We use Electrochemical Machining (ECM) to precisely shape specialty metal alloys for aerospace, energy, industrial, semiconductor, and medical customers. Our team owns the full technology lifecycle under one roof: chemistry, machine design, tooling, process development, production, inspection, and continuous improvement. We build specialized manufacturing technology because the equipment and processes we need often do not exist off the shelf. We are a small, growing company with high ownership, solving deep technical problems with real-world impact. We think like engineers, chase root causes, and move quickly from R&D into real production.

Job Description

• Design machines, fixtures, tooling, and mechanical systems that meet demanding accuracy, repeatability, and performance requirements.
• Develop mechanical concepts from rough requirements through detailed design, review, release, build support, testing, and improvement.
• Own meaningful portions of a design from concept through CAD, drawings, BOMs, vendor coordination, procurement support, troubleshooting, and iteration.
• Analyze designs for stiffness, strength, thermal effects, vibration, tolerance stack-up, alignment, serviceability, and manufacturability.
• Select and integrate motion components, bearings, structures, actuators, sensors, tooling, and precision assembly features.
• Design sheet-metal parts, machined components, weldments, brackets, enclosures, fixtures, and assemblies as needed.
• Create or review detailed mechanical designs, drawings, BOMs, and released design packages.
• Participate in design reviews and use engineering judgment to identify risks, tradeoffs, and better solutions.
• Collaborate with process engineers, electrical engineers, controls engineers, machinists, technicians, and vendors.
• Support machine assembly, commissioning, troubleshooting, and testing when engineering involvement is needed.
• Improve Voxel's machine design standards, design calculations, error-budgeting methods, and engineering workflows.
• Help make each generation of Voxel machines more accurate, repeatable, reliable, manufacturable, and cost-effective.

About You

• You are an engineer who wants to understand why a system works, why it fails, and how to make it better.
• You are comfortable working on problems where mechanics, controls, chemistry, heat, fluid flow, manufacturing, and measurement all interact.
• You do not hide behind narrow job boundaries. You ask good questions, use facts over opinions, and care about whether the machine actually performs.
• You are detail-oriented, but you do not get stuck in the details. You know when precision matters, when a design needs deeper analysis, and when the right answer is to make a practical decision and keep the project moving.
• You are excited by the challenge of building equipment with accuracy and repeatability that Voxel does not yet have today.
• You take pride in designing practical systems that can be built, tested, improved, and scaled.
• You align with Voxel’s Core Values: Expect Excellence, Do Right By Others, Always Getting Better, What Would Happen If…

Qualifications

• 4+ years of professional mechanical design experience with machines, fixtures, tooling, automation equipment, precision mechanisms, production equipment, or complex mechanical assemblies.
• Demonstrated ability to design real mechanical systems, not just individual parts.
• Experience creating or reviewing detailed mechanical designs, drawings, BOMs, and released design packages.
• Working knowledge of motion components such as linear guides, bearings, actuators, motors, encoders, sensors, and mechanical drive systems.
• Ability to create and review engineering calculations, tolerance stack-ups, and design trade studies.
• Practical understanding of CNC machining, fabrication, assembly, inspection, and design-for-manufacturing.
• Strong problem-solving ability, attention to detail, and willingness to work through ambiguity.
• Engineering degree or equivalent demonstrated technical capability required.
• Experience is valued, but intelligence, ownership, curiosity, and ability to learn are critical.

Mandatory Requirement

Due to U.S. government contract requirements, all employees must be either a U.S. Citizen or Permanent Resident with a valid I-551 card (green card). Work Visas are not acceptable.

Application Instructions

To apply, submit a cover letter describing why you are interested in working at Voxel and our mission. A portfolio or project examples are optional but valued, including photos, CAD screenshots, drawings, test results, or project summaries without confidential details.
