About CoLab
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, AutoReview, scans designs for common errors or non-compliance with your standards and guidelines. AutoReview 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 is a senior UI role for someone who cares deeply about systems, not just screens. As a Software Developer IV focused on UI, you’ll sit on our Build UI team and help define how CoLab’s interface is built, scaled, and evolved. Your work will directly shape our design system (Schematic), the components teams rely on every day, and the quality bar for UI across the product. You won’t just consume a design system — you’ll help build and harden it. That means collaborating closely with Product Design, Product Engineering, and other front-end developers to turn patterns into durable, well-tested components that scale as the product grows.
If you’ve ever been frustrated by brittle UI foundations, undocumented components, or “one-off” solutions that quietly become permanent — this role exists to fix that.
Our Ideal Candidate
You’re a senior UI engineer who thinks in components and contracts and systems, not pages. You’ve worked inside a real design system before and understand the tradeoffs required to keep it flexible without letting it collapse into chaos.You enjoy working closely with designers, can push back thoughtfully when something won’t scale, and take pride in building accessible, well-documented UI primitives that other engineers trust and reuse. You’re comfortable setting direction and standards, mentoring other engineers, and raising the quality bar for UI beyond the code you personally write.
What You’ll Own
- Build, evolve, and maintain CoLab’s design system (Schematic), hosted in Storybook
- Develop high-quality, reusable React components used across the product
- Set standards for component architecture, testing, documentation and accessibility
- Write and maintain component-level tests
- Partner closely with Product Design to translate intent into scalable UI patterns
- Review UI code with an eye toward consistency, accessibility, and long-term maintainability
- Help other engineers move faster by giving them strong UI primitives and clear guidance
Qualifications
- 5–7+ years of professional frontend or UI engineering experience
- Deep, hands-on experience with React
- Prior experience building and scaling a design system used across multiple teams or products
- Strong experience using Storybook as a system of record, not just a demo tool
- Experience writing and maintaining component level tests
- Strong experience building accessible UI components, including keyboard navigation, focus management, and screen-reader support
- Experience managing component lifecycle, including versioning, deprecations, and backward-compatible updates in shared systems
- Strong communication skills when collaborating with designers and engineers
Nice to Have
- Experience extending or building on top of headless or foundation UI systems (such as Radix)
- Experience leveraging Figma-based workflows to connect design system definitions with production code (e.g., Code Connect, MCP, or similar tools)
Extra Details
- Full-time, permanent role with competitive compensation and equity
- Remote-friendly across Canada
- Benefits include extended health coverage, unlimited PTO, and RRSP matching
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.

What We Do
Engineers need better tools for working together. CAD and PLM systems aren’t built for the design conversations where collaboration truly happens. So engineers go outside of them, using emails and slideshows to get the job done. But when these critical design discussions live in siloed, manual tools, you’re missing vital insights on why engineering decisions are being made, what needs to improve, and how to steer your people in the right direction.
After struggling with the traditional email, PowerPoint, and screenshot-driven collaboration process used by over 90% of manufacturing teams today, our founders made a decision: if better tools didn’t exist, they’d build them. And so CoLab began.
CoLab is a web-based collaboration tool that lets your team share CAD, provide feedback with full mechanical context, and capture the critical design data that your other systems don’t—giving you a design review and collaboration process that’s standardized, simplified, and twice-as-fast.
Today CoLab is trusted by Fortune 500 companies like Johnson Controls and Hyundai Mobis, who use the platform to accelerate design cycles by 51%, drive continuous improvement, and reduce product costs and changes.
