About The Position

Valinor Reflex is seeking a Mechanical Engineer to join our small, hands-on team. You will help design and build a low-profile, integrated hardware system built to perform in mission-critical environments. This role is ideal for an engineer who not only excels in CAD, but deeply understands how designs translate into real-world manufacturing, assembly, and field performance.
You will work closely with electrical engineers and own critical parts of the mechanical system from concept through production. If you're comfortable moving fluidly between design work, vendor coordination, and hands-on assembly, and you're energized by a fast-paced, build-first environment, we'd love to meet you.

Requirements

• Bachelor's degree in Mechanical Engineering or a closely related field
• 3-5 years of experience in mechanical design, with a track record of taking products from CAD through manufacturing and into assembly
• Strong proficiency in SolidWorks or comparable CAD tools
• Hands-on experience with electromechanical systems, including collaboration with electrical engineering teams
• Solid understanding of manufacturing processes including CNC machining, 3D printing and post-processing, and injection molding
• Working knowledge of material selection, tolerancing, and design for manufacturability (DFM) principles
• Experience assembling or handling sensitive electronic hardware
• Familiarity with thermal management and heat dissipation techniques
• Experience coordinating with vendors, suppliers, or contract manufacturers
• Comfortable working in an early-stage environment where you'll help build the foundation, not just work within it
• This role requires the candidate be eligible to obtain and maintain a U.S. security clearance. Active clearance preferred.

Responsibilities

• Design mechanical components and assemblies in SolidWorks, with a focus on producing parts that are manufacturable and production-ready from day one
• Collaborate closely with electrical engineers, including within Altium workflows, to co-design tightly integrated electromechanical systems
• Own key decisions around material selection, fabrication processes, tolerancing, and adhesives
• Design for thermal performance and heat dissipation within constrained form factors
• Assemble and integrate sensitive electronic hardware with mechanical systems
• Partner with vendors and contract manufacturers to drive prototyping and component production
• Iterate quickly based on testing outcomes, failure analysis, and real-world performance feedback

Benefits

• Competitive salary, equity packages, and benefits, including health, dental, and vision insurance - fully covered for employees, 401K, development stipends, among others.
• Unlimited PTO and two-week company holiday at the end of every calendar year.
• We are a pro-mental health and pro-family company - we actually encourage employees to spend time with themselves and their families. Valinor also provides fertility benefits to those just beginning that journey.
• Fun work environment - we like to laugh and take care of each other, but we also deeply respect the mission in front of us.
