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 a Canadian company to watch by The Globe and Mail and Financial Post.  About the Role CoLab has major accounts with meaningful expansion potential, and a top 100 list of strategic prospects we want to win. Today, that motion is mostly account team-led. Customer success and sales own the relationship and pull in brand design or product marketing reactively. What we don’t have yet is a proactive strategy to influence new (and more senior) stakeholders, shape perceptions about our brand and product, and drive pipeline (expansion + new biz) within our Top 100 accounts. That’s where you come in. As Sr. Director, Growth Marketing - Major Accounts, you’ll report to the CMO and own growth marketing for CoLab’s most important customer and prospect accounts. Your job is to help us move from isolated team adoption to broader enterprise expansion, and from cold strategic targets to high-quality pipeline. This is a leadership role, but we expect you to be hands on. In your first 90 days, you’ll get deep into 3–5 accounts, partner with Strategic Account Directors, AEs, and Strategic CSMs, and run real plays. That might mean an onsite education session, an executive webinar, a lunch and learn, a field event, account-specific content, or a curated experience at our user conference. You’ll shape campaigns and get work done by recruiting (through influence) design, product marketing, digital/ops, and field marketing help. When you find a play that works, we’ll invest in dedicated resources for your team, so you can scale it. JOB RESPONSIBILITIES * Own expansion and new business pipeline creation across CoLab’s Top 100 customer and prospect accounts, with accountability for pipeline quality, ASP, and progression. * Build CoLab’s major account growth marketing motion from the ground up: define the strategy, test account-specific plays, measure what works, and turn the strongest experiments into repeatable programs. * Collaborate with Sales and Customer Success to identify the highest-potential account opportunities, align on account strategy, and create marketing plans that help expand CoLab from team-level adoption to enterprise-wide relevance. * Translate product positioning, account intelligence, customer usage signals, and sales insights into tailored campaigns that influence senior stakeholders and create commercial urgency. * Architect and oversee integrated account plays across field marketing, executive events, webinars, lunch and learns, customer education, digital campaigns, lifecycle programs, and custom content. * Help shape how CoLab shows up as a strategic AI partner inside major engineering organizations — not just as a point solution, but as a platform worthy of broader enterprise commitment. QUALIFICATIONS * 10+ years of B2B SaaS marketing experience, with meaningful experience in enterprise ABM, demand generation, field marketing, expansion marketing, or strategic account growth. * Proven track record owning or materially influencing pipeline targets for complex, high-ASP enterprise accounts. * Strong commercial judgment: you understand how enterprise opportunities are created, shaped, multi-threaded, and progressed through Sales and Success partnership. * Ability to operate credibly with senior revenue leaders while working directly with AEs, Strategic Account Directors, and CSMs closest to the account. * Strong briefing and cross-functional leadership skills; you can turn an ambiguous account opportunity into a focused plan that creative, product marketing, digital, ops, and field teams can execute. * Comfortable building the first version of a motion yourself before asking for dedicated headcount, budget, or process 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.
