Mechanical Engineer; Onsite

Alchemy is currently in search of a Mechanical Engineer in Waterloo, ON.

Alchemy is a nanotechnology company building breakthrough solutions for the automotive and defence industries. We're transforming legacy sectors by vertically integrating our proprietary nanocoatings into category-defining, ready-to-use products. Our flagship technologies:

• Exo Shield: the world's leading windshield protection film for the automotive aftermarket
• Crypsis Class: a multispectral camouflage coating platform for defence applications

We are at the growth-stage of our journey and are focused on sustainable top-line growth across both our automotive and defence business units. Alchemy is backed by leading investors and incubators in Canada, USA, and France such as Y-Combinator, Stanford-StartX, Pathfinder, Pembroke, Name Silo, and more. Our team is a diverse, tight knit group of engineers, scientists, and business professionals that likes to spend time together in and out of the office, whether that is weekly badminton nights or team lunches.

We are a team passionate about cars, cool technology, and working together to dominate the market segments we operate in.

We're hiring a Mechanical Engineer to take our automotive products from design intent to repeatable production. Our products are precision-fit: each one is engineered to a specific vehicle, which means complex freeform geometry, custom tooling, and tightly controlled manufacturing processes that have to hit both dimensional and optical quality targets. This role owns that engineering chain end to end — digitizing and modelling geometry, designing and sourcing the tooling required to make it, developing and qualifying the process, validating the result, and handing a documented, repeatable process to Manufacturing.

This is a deliberately broad, hands-on individual-contributor role. You will be the technical authority on design and process decisions and the person who sets the standards the rest of the team works to. You'll mentor one to two mechanical engineers and co-op students and help raise the technical bar of the team, but your value comes from your own judgment, CAD, and time on the floor rather than from managing headcount.

You'll report to the Head of Automotive Technology and work daily with Product, Operations, and Manufacturing.

Salary up to $ + equity (experience dependent)

Onsite - Waterloo - 5 days a week

• Model complex freeform geometry and reverse-engineer parts from 3D measurement data
• Own the design standards that drive fit, manufacturability and quality — tolerances, surface treatment, design rules, and part categorization
• Lead design reviews and act as the technical approver before designs are committed to tooling
• Improve the design pipeline itself: better methods, templates, and automation to remove repetitive work

• Specify, design and source custom tooling and fixtures, including materials, construction, service conditions, tolerances and inspection criteria
• Own tooling through its lifecycle — commissioning, durability, rework and replacement
• Balance tooling cost against performance and life, and make the tradeoff explicit rather than implicit

• Develop and qualify manufacturing processes for polymer and film-based products, including thermal and pressure-driven forming and finishing operations
• Establish robust process windows and understand how the key variables interact, rather than tuning by feel
• Diagnose defects to root cause, using structured experimentation and retained evidence
• Release processes only when quality, repeatability and durability requirements are all met
• Hand processes to…
