About CoLab

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

CoLab is the AI platform for driving stronger engineering decisions. Every design review in CoLab builds a knowledge repository of design feedback, decisions, and lessons learned - which AI agents draw from to flag issues on future designs before they compound. The more your team works in CoLab, the smarter it gets and the faster you arrive at the ideal design. Companies like Ford, Komatsu, and Johnson Controls use CoLab to catch issues earlier, eliminate rework cycles, and bring products to market faster.

Founded in St. John’s, Newfoundland, CoLab has grown quickly from our first customer in 2019 to a rapidly scaling company. We’ve recently been recognized on Deloitte’s Fast 50™ and Fast 500™, and named Canadian company to watch by The Globe and Mail and Financial Post. 

About the Role: 

Mechanical engineering teams rely on a complex ecosystem of CAD, PLM, and enterprise systems to design, review, and manufacture products. At CoLab, we're building software that fits naturally into those workflows.

As a Senior Full Stack Developer, you'll play a key role in making that possible. You'll build the integrations and platform capabilities that connect CoLab with the systems our customers use every day, helping engineering organizations review designs faster, collaborate more effectively, and make better decisions throughout the Mechanical Engineering Lifecycle.

This role is a great fit for someone who enjoys solving technically challenging integration problems. Ideally you’ve spent your career building web applications and focused within heavy integrations. 

You'll work closely with Product, Design, Customer Success, and fellow engineers to translate real customer challenges into scalable software. One week you might be improving how CoLab integrates with a CAD application. The next, you could be investigating a complex customer workflow spanning PLM, ERP, and engineering data to eliminate friction for thousands of engineers.

Job Responsibilities

  • Understand complex customer problems and requirements and work in a team to build a solution that adds value for the customer and the product as a whole
  • Collaborate with other team members to design and plan complex scopes of work from product requirements and UI/UX designs
  • Develop, test, and ship critical user-facing features on a regular basis
  • Develop, test, and maintain robust and scalable APIs.
  • Participate in code reviews and help your team deliver high-quality software
  • Champion all aspects of the user’s experience, with a focus on clarity and speed
  • Contribute to tech technology direction and best practices
  • Mentor, support, and be an information source to junior developers

Qualifications

  • 8+ years of professional, hands-on development experience
  • Experience working on SaaS, large-scale distributed systems
  • Consistent track record of building and maintaining highly scalable products
  • Proficient with Java and / or C#
  • Experience with version control, release management, and CI/CD workflows
  • Exposure to Javascript/Typescript, Python, HTML and CSS is considered an asset 
  • Experience with front-end build, package-management & testing tools such as Webpack, NPM, Jest, Cypress, etc 
  • Experience writing robust automated tests, including unit and integration tests using Jest, as well as end-to-end (E2E) tests using Cypress or Playwright.
  • Hands-on experience with relational databases (e.g., PostgreSQL, MySQL), NoSQL databases (e.g.: DynamoDB) and querying frameworks/APIs.
  • Experience with Git workflow (pull requests, code reviews)
  • Passion for working in teams with emphasis on respect and continuous improvement
  • Willingness to raise your hand when you see something could be done / built better

Extra Details

  • Compensation: This is a full-time, permanent position with an attractive compensation package that includes a stock options package.
  • Benefits: This role offers an extended health and benefits package that includes unlimited paid vacation and RRSP matching.
  • Remote/Hybrid Work: Our main office location is in St. John’s, NL where we offer hybrid and remote opportunities. This role has the flexibility to work from anywhere within Canada. 

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.
