Mechanical Engineer II/III

Opterus Research & Development is an innovative aerospace company based in Loveland, Colorado, specializing in deployable space systems and high-strain composite structures. We combine cutting-edge composite materials, origami-inspired architectures, and elegant engineering to deliver lightweight, high-performance structural systems for commercial, defense, and scientific missions.

As a Mechanical Engineer II or III, you will help design and develop lightweight, high-performance deployable structures and integrated systems for spacecraft and lunar surface missions. This role is ideal for someone with a passion for aerospace mechanisms, composites, or deployable structures, and who thrives in a fast‑paced, iterative environment.

• →Design and analyze deployable systems
• →Take ownership of developing structural components and mechanisms from initial ideation through prototyping, qualification, and production
• →Create CAD assemblies and documentation using SolidWorks to produce detailed models, build documentation, and mechanical drawings
• →Support hardware assembly and integration by performing hands on work in a cleanroom environment to ensure precise and reliable system builds
• →Test and validate structural components by executing performance tests, analyzing results, and confirming flight readiness
• →Iterate and prototype designs frequently, characterizing performance, documenting findings, and refining concepts based on test data
• →Collaborate across engineering and production teams to meet quality, schedule, and budget goals while ensuring alignment throughout the project lifecycle
• →Solve complex engineering challenges by adapting quickly, pivoting when needed, and proposing innovative solutions to unforeseen issues
• →Provide mentorship for junior Mechanical Engineers
• →Perform additional engineering duties as required to support mission and program success

• BS in Mechanical, Aerospace, or related engineering field
• Mechanical Engineer II: 2+ years experience
• Mechanical Engineer III: 5+ years experience
• Experience with spacecraft design, deployable structures, and/or composites strongly preferred
• Demonstrated creative problem‑solving and engineering intuition
• Proficiency in GD&T and standard analysis practices
• Fluency in CAD (SolidWorks preferred)
• Strong communication and organizational skills
• Ability to work both independently and collaboratively
• Proficiency with Microsoft Office Suite
• US citizen or permanent resident required
