About the RoleWe are building a dedicated product growth team, and we're hiring a Growth Engineer to operate as a full, self-sufficient software engineer within it. Reporting to the Director of Product Growth, you'll work alongside our Product Manager and Product Designer on the highest-leverage problems in the business - starting with onboarding, activation, and revenue conversion.
This is not a traditional engineering role. We act as a SWAT team: we go where the data takes us, we move fast, and we change direction without hesitation when the numbers tell us to. The code you write today may be replaced next sprint - and that should excite you, not bother you. Most engineering roles reward stability, depth, and long-term ownership of a system; this one rewards speed, adaptability, and measurable business impact. You will own experiments end to end and be personally accountable for outcomes, not just outputs.
Responsibilities- Build, ship, and iterate on onboarding flows, activation surfaces, and conversion experiments that directly impact sign-up-to-paid rate
- Design and run A/B and multivariate experiments, instrument them properly, and close the loop on what the data shows
- Own experiments end to end - scoping, building, shipping, measuring - with personal accountability for outcomes
- Build lightweight internal tools and growth infrastructure when they unblock the team
- Contribute to anything that measurably moves a growth needle, regardless of where it sits in the product
Requirements- 3 to 6 years of professional full-stack development experience; our stack is TypeScript, React.js, Node.js, PostgreSQL, and AWS
- Hands-on experience building with AI technologies: LLMs, agents, embeddings, or AI-powered product surfaces - you are not intimidated by rapidly evolving AI tooling and actively seek it out
- Demonstrated comfort owning the full development cycle independently: scoping, building, shipping, and iterating without handholding
- A genuine eye for clean, well-crafted UI and UX - you don't need a designer next to you to produce something that feels right
- Low ego about your own code: you build what serves the objective, not what you're proud of; rewrites and reversals are part of the job
- Strong instincts for experimentation: you think in hypotheses, you instrument your work, and you let data drive the next decision
- Proactive by default: you identify problems before they're handed to you and come with a proposed path forward
- Clear, direct communication in English (French is an asset) - you'll be working in a small team where everyone needs full context, fast
Benefits- Work with a talented and passionate team
- 4 weeks of vacation
- Paid sick and parental leave
- Comprehensive health, dental, vision, travel, and life insurance
- Funding for education and skills improvement
- Fully-stocked fridge and cupboard - we take snacks seriously
- Your own desk - no 'hot-desk'-style sign-up systems
