Senior Customer Success Manager

About CoLab

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

We build AI for engineers designing cars, medical devices, and jet engines. Products this complex aren't sketched and sent to production. Teams spend months on iterations, reviews, and tests, predicting how every part performs before anything is built. CoLab is where those reviews happen, and we capture the rationale behind every change. Other tools show what changed between versions. Only CoLab knows why. That's how our AI helps manufacturers like Bobcat, Triumph Motorcycles, and GE Appliances make better decisions, eliminate rework cycles, and get to market faster.

Proudly based in St. John’s, Newfoundland, CoLab started with one customer in 2018. Since then we’ve raised a $72M Series C , been named the 57th fastest growing company in North America by Deloitte ( Fast 500™ ), signed multi-year AI partnerships with companies like Bombardier , and grown to a team of 250+.

About the role

As a Senior Customer Success Manager , you will lead the post-sale customer journey for a portfolio of our largest Enterprise customer, with a focus on driving measurable business results, product adoption, long-term retention. You’ll partner closely with engineering and business stakeholders to align execution to customer goals, drive product adoption, and ensure CoLab becomes integral to customers’ workflows.

You’ll be part of a cross-functional account team, working closely with Customer Engineering Advisors to deliver technical enablement and collaborating with Sales partners to support retention and expansion. This is a growth-oriented role for someone who thrives in fast-paced, technical environments and has a proven track record of driving product adoption to influence long-term retention and satisfaction.

In-person customer engagement is a key part of this role’s success. On-site visits have consistently driven higher adoption, deeper relationships, and better business outcomes for our customers. We recognize personal travel constraints may arise and we expect Senior CSMs to proactively plan for and prioritize in-person opportunities.

Twice annually we bring together all CoLabers at our HQ in St. John’s, Newfoundland (typically in June and December), to participate in company Team Week.
