What are the responsibilities and job description for the Senior Mechanical Designer position at Round-Peg Solutions (RPS)?
Are you a Senior Mechanical Designer who wants to own designs that actually get manufactured ?
Do you enjoy working closely with engineers to take products from concept to production?
Want to be part of a team building real aerospace hardware used in mission-critical systems?
Join a New Jersey Top Workplace (3 years running) delivering high-performance control systems into the aerospace & defense sector — with a strong reputation for engineering quality, stability, and long-term growth.
As a Senior Mechanical Designer (MCAD), you’ll play a key role in supporting new product development, working alongside engineers to deliver fully detailed, manufacturable designs across complex electromechanical systems.
What You’ll Be Doing as a Senior Mechanical Designer (MCAD):
- Creating detailed 3D models and assemblies using Creo / Windchill
- Producing fully annotated manufacturing drawings with GD&T (ASME standards)
- Performing tolerance stack-ups to validate fit and function
- Supporting PDR / CDR design reviews with engineering teams
- Managing and updating design documentation (ECNs / AECNs)
- Developing and maintaining standard part libraries for reuse
- Working closely with engineers to evaluate and improve design feasibility
- Supporting design for manufacture across machining processes (CNC, sheet metal, etc.)
The ideal Senior Mechanical Designer (MCAD) will bring:
- 3 years’ experience as an electro-mechanical / CAD designer
- Strong experience with PTC Creo (4.0 ) and Windchill (12.0)
- GD&T, fits, tolerances, and materials selection
- Solid understanding of mechanical design principles
- Knowledge of manufacturing processes such as turning, milling, drilling, tapping
- Experience with electromechanical packaging / assemblies is a plus
- Exposure to fluid components (seals, bearings) is a plus
- Strong communication and documentation skills
- US Citizen (required)
Compensation : up to 110k (DOE)
Location: Whippany (On-site) , Flexibility for Contractors
Direct hire (full time) W2 contract options available
Why join?
- Work on real aerospace hardware, not theoretical design work
- Be embedded in the full product lifecycle, not siloed drafting
- Join a stable, growing A&D company with strong engineering culture
- High visibility role working directly with engineering teams
If you’re looking for a role where you can own designs, influence engineering decisions, and see your work built into real systems, this is worth a conversation.
