Mechanical Engineer

Job Title:

Mechanical Engineer

Job Description

This role owns the end-to-end design and engineering lifecycle of complex mechanical assemblies, systems, and specialized tooling for large-format robotic 3D printing construction equipment. The Mechanical Engineer performs detailed analyses, creates robust documentation, and collaborates closely with cross-functional teams to deliver high-quality, reliable, and manufacturable products in a fast-paced, innovative environment.

Responsibilities

* Owned the end‑to‑end design and engineering lifecycle of complex mechanical assemblies, systems, and specialized tooling for large‑format robotic 3D printing construction equipment.

* Performed advanced structural, thermal, and kinematic analyses using hand calculations and FEA/CFD to evaluate stress, fatigue, deflection, thermal performance, and dynamic behavior, driving risk‑informed design decisions.

* Created and controlled comprehensive engineering documentation, including 3D CAD models, ASME Y14.5‑compliant drawings, and accurate BOMs within PDM/PLM systems.

* Led cross‑functional design reviews and collaborated with mechanical, electrical, software, manufacturing, and field teams to optimize designs for performance, manufacturability, reliability, and cost.

* Supported prototyping, validation, and field deployment by executing V&V plans, conducting FMEA‑based risk mitigation, troubleshooting build and field issues, and implementing rapid design updates.

Essential Skills

* Bachelor's degree in mechanical engineering or a related field, or equivalent experience.

* 3-5+ years of experience in a hands-on mechanical design or product development role, preferably involving robotics, automation, heavy equipment, or large machinery.

* Proficiency with Solid Works for 3D CAD modeling and mechanical design.

* Experience with Solid Works Simulation or equivalent tools; ANSYS experience is considered transferable.

* Demonstrated experience designing and iterating R&D prototypes or the ability to design and iterate quickly while maintaining high-quality output.

* Familiarity with ASME Y14.5 and Geometric Dimensioning and Tolerancing (GD&T) for creating and interpreting detailed 2D drawings.

* Experience with finite element analysis (FEA) and thermal analysis (expert-level proficiency not required).

* Knowledge of machine design principles and new product development processes.

* Ability to perform engineering hand calculations to support structural, thermal, and kinematic analyses.

* Strong documentation skills for creating accurate BOMs, drawings, and models and maintaining them within PDM/PLM systems.

* Ability to collaborate effectively in cross-functional teams and communicate technical concepts clearly.

* Hands-on approach to troubleshooting mechanical issues in prototypes and deployed systems.

Additional

Skills & Qualifications

* Experience with FEA beyond basic familiarity, including setting up and interpreting simulations for complex mechanical systems.

* Experience designing, integrating, and troubleshooting fluid or hydraulic systems.

* Experience designing hardware for prolonged use in dusty, dirty, or harsh outdoor environments.

* Experience in robotics, automation, heavy equipment, or large machinery development.

* Experience participating in or leading Failure Modes and Effects Analysis (FMEA) activities.

* Familiarity with verification and validation planning and execution for mechanical systems.

* Comfort working in a fast-paced, early-phase company environment where rapid iteration and continuous improvement are expected.

Work Environment

This is a full-time, onsite role with typical hours from 8:00 a.m. to 5:00 p.m., with flexibility to work overtime as needed to support project milestones, builds, and field activities. The work environment is a fun, collaborative startup setting where you will work closely with engineers, technicians, and cross-functional partners on advanced robotic 3D printing construction equipment. The culture emphasizes innovation, hands-on problem-solving, and rapid iteration.

Paid time off includes a company-wide shutdown week from December 26th through 31st, along with 10 paid holidays:
