🚀 Role Summary

• This role is critical for the design, development, and hands-on implementation of bespoke robotic systems and specialized hardware at the National Robotics Engineering Center (NREC).

• The position emphasizes a strong blend of mechanical design, rapid prototyping, and practical system integration, with a focus on bringing concepts from CAD to physical reality.

• Successful candidates will own the entire lifecycle of their designs, including assembly, wiring, and initial hardware debugging, contributing to applied research and real-world solutions.

• The role requires adaptability and a collaborative spirit, operating in an agile environment that bridges academic research and industrial application.

📝 Enhancement Note: The job description highlights a "lean, agile robotics applied research team" that "builds bespoke, intelligent robotic systems from the ground up." This implies a need for engineers who are not only technically proficient but also highly adaptable and comfortable with ambiguity, common in applied R&D settings. The emphasis on owning the design lifecycle and wearing multiple hats suggests a fast-paced environment where individual initiative and hands-on contribution are highly valued.

📈 Primary Responsibilities

• Lead the mechanical architecture and detailed design of custom robotic systems, specialized end-effectors, and unique enclosures using advanced 3D CAD software.

• Execute rapid prototyping and fabrication of concepts using a variety of methods including 3D printing, CNC machining, laser cutting, and traditional fabrication techniques to expedite design validation.

• Take ownership of the physical build process, including meticulous mechanical assembly and the neat, reliable routing of electrical wiring and wire harnesses.

• Drive hardware bring-up and testing, utilizing a working familiarity with basic electronics debugging tools such as multimeters and oscilloscopes to isolate and resolve hardware issues.

• Investigate ambiguous, high-level project requests, scope technical requirements, and clearly communicate potential trade-offs to stakeholders before commencing detailed design and execution.

• Collaborate closely with multidisciplinary teams, including software and systems engineers, to ensure seamless integration of mechanical designs into functional robotic solutions.

• Contribute to the exploration phase of projects, researching and evaluating new technologies, materials, and manufacturing processes to inform design decisions.

• Support the development and integration of sensors and machine vision components within custom robotic hardware.

📝 Enhancement Note: The responsibility to "Scope & Explore" and "Take ambiguous, high-level requests, investigate the constraints, and communicate technical trade-offs before diving into execution" strongly indicates that this role requires significant problem definition and critical thinking skills, not just execution. This is a key differentiator for applied research and development roles where the problem itself may not be fully defined at the outset.

🎓 Skills & Qualifications

Education: Bachelor’s degree in Engineering (Mechanical, Mechatronics, Robotics, or a closely related field) or equivalent practical experience.

Experience: 1-3 years of relevant engineering experience, with openness to a range of levels from motivated junior engineers to seasoned professionals, emphasizing mindset and willingness to be hands-on.

Required Skills:

• Strong proficiency in 3D CAD modeling software (e.g., SolidWorks, Fusion 360, Onshape).

• Demonstrated practical experience with mechanical assembly, hand tools, and an understanding of structural fits and tolerances.

• Functional knowledge of electronics, including comfort in reading schematics, soldering, fabricating wiring harnesses, and diagnosing basic electrical faults.
