Mechanical Engineer II​/III

About Opterus

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 Solid Works 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 needed 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 (Solid Works preferred).
• Strong communication and organizational skills.
• Ability to work both independently and collaboratively.
• Proficiency with Microsoft Office Suite.
• US citizen or permanent resident required.

• Flexible hybrid schedules (9/80 or 10/80) with at least two in-office days per week.
• Opterus covers 100% of employee premiums and 70% of dependent premiums.
• Medical, Dental, Vision, STD, LTD, Life & AD&D.
• 401(k) with 4% company match.
• 9 paid holidays.
• Mechanical Engineer II: $90,000-$118,000.
• Mechanical Engineer III: $114,000-$140,000.
