Full Job Description

About the role

We're looking for a mechanical engineer to own the physical design of our products and help lead production — both improving what we already make and bringing new products to life. This is a rare chance to take real ownership early: you'll carry designs from concept, to CAD, to a part you can hold in your hands.

This role is what you make of it. We're looking for a self-starter who can take the reins and run without hand-holding — someone who will make the position their own and help shape the future of design and product direction at Innovative Timing Systems as we grow. We'll give you ownership and trust; we expect you to run with it.

We're hiring for the long term. We want someone who can grow with us and step into a permanent, senior role as the company scales.

What you'll do

Own the mechanical design of our products, from concept through detailed CAD models and drawings
Prototype quickly with 3D printing, then test, iterate, and refine
Fabricate and produce parts — CNC and other shop processes — for both prototypes and production runs
Lead and improve production of our existing products, and stand up production for new ones
Work closely with the whole team across design, sourcing, assembly, and testing to ship products that work

What you'll bring

Above all, we care about attitude and initiative. If you're a self-starter with a great attitude — a hard worker who can take a problem and run with it, a genuine team player, and flexible enough to jump on whatever the day needs — you'll thrive here.

A self-starter who takes initiative and works independently — we'll hand you ownership, not step-by-step direction
Real, hands-on experience actually making things — we want proof you've designed and built, not just studied the theory (a portfolio or project examples strongly preferred)
Strong CAD skills — Fusion 360 preferred (or solid experience in a comparable tool you can transfer quickly)
Hands-on 3D printing experience
Currently pursuing or recently completed a degree in Mechanical Engineering (or equivalent hands-on experience)
A great attitude, strong work ethic, and eagerness to learn and adapt

Nice to have

Design & analysis

GD&T (geometric dimensioning & tolerancing) and detailed, well-organized engineering drawings
FEA / simulation for stress, thermal, or motion (e.g., Fusion 360 or SolidWorks Simulation)
Material knowledge across plastics (PLA, ABS, PETG, nylon) and metals (aluminum, steel), and processes like injection molding or sheet metal
Rendering and visualization for product shots and pitches (e.g., KeyShot)

3D printing

Bambu Lab printers and slicers like Orca Slicer, Bambu Studio, Cura, or PrusaSlicer
Both FDM and SLA (resin) printing

CNC & fabrication

CAM and CNC machining (Fusion 360 CAM, Mastercam, or HSMWorks)
CNC routing with VCarve, and an understanding of CNC mills and routers
Laser cutting/engraving (e.g., LightBurn), and comfort with shop measurement tools like calipers and micrometers

Also a plus

Personal builds — maker projects, robotics, competitions, side projects (we love to see them)
Basic electronics or mechatronics (e.g., Arduino) and familiarity with BOMs and production workflows

Pay: $25.00 - $30.00 per hour

Work Location: In person
