About Co Lab
At CoLab, we want to help mechanical engineering teams bring life-changing products to market years sooner.

CoLab is a cloud‑based platform for engineering design review. We make it easy for subject‑matter experts (SMEs) across your business to access, evaluate, and comment on 2D drawings and 3D models. Our built‑in AI peer checker, Auto Review, scans designs for common errors or non‑compliance with your standards and guidelines. Auto Review creates markups and comments on your files, in context – just like a human checker.

With CoLab, human SMEs and AI work together to help you make better decisions and improve designs faster. We automatically capture knowledge from across your global business that would otherwise be buried in emails, spreadsheets, slide decks, and unknown locations in SharePoint or PLM. Then, we make sure every lesson learned and every design guideline is applied exactly when it matters.

Companies like Johnson Controls, Komatsu, Schaeffler, and Polaris have launched products 40% faster, cut BOM costs by 50%, and reduced quality escapes by 15% in 1 year.

About

The Role
This role sits on our  Build Viewing  team — the group responsible for how engineers experience CoLab at its core.

You'll work on the rendering and interaction layer for complex 2D and 3D engineering files. That includes everything from high‑performance model rendering to markups, measurements, wall‑thickness analysis, and draft analysis. If something appears on the screen when an engineer opens a design in CoLab, your team likely built it.

This is a  front‑end heavy  full‑stack role. You'll spend most of your time in the UI layer, building fast, intuitive experiences on top of complex geometric and analysis engines. But you won't be isolated from backend or infrastructure decisions—you'll contribute across the stack when needed.

The challenge? Visibility and urgency. Engineers rely on these features daily. Sales relies on them in enterprise deals. Leadership has opinions. Customers have requests. Priorities can shift. You'll need to build with focus and resilience, even when the spotlight is on. If you like building technically demanding interfaces where performance, precision, and usability all matter — you'll thrive here.

Our Ideal Candidate
You enjoy hard technical problems — especially the kind where rendering performance, geometry, and UX intersect.

Contribute to technical decisions that shape the future of CoLab's core viewing experience

Respond to high‑impact feature requests with pragmatic, well‑structured solutions

Qualifications

5+ years of experience in full‑stack development, with strong front‑end focus

Deep experience with modern front‑end frameworks (e.g., React)

Strong understanding of rendering performance, state management, and complex UI systems

Experience working with 2D/3D graphics (WebGL, Three.js, or similar)

Ability to reason about geometric data and technical problem spaces

Experience collaborating in cross‑functional product teams

Bonus

Experience with CAD file formats or engineering software

Familiarity with computational geometry or 3D analysis techniques

Remote‑friendly within Canada, with hybrid options in St. John's, NL

Equity Note
Frequently cited statistics show that people who identify with historically marginalized groups are likely to apply to jobs only if they meet 100% of the qualifications. We encourage you to help us break that statistic and apply even if you don't meet every single qualification—your potential is what matters most to us.
