This role sits at the intersection of AI engineering and application development. You’ll build customer-facing features from scratch, while also helping us integrate and scale the AI infrastructure that power them. You're deeply fluent in TypeScript and React, strong enough on the backend to own a feature end-to-end, and have meaningful experience building AI applications. You craft fast, polished, reliable software and you're drawn to problems that are genuinely unsolved.

We're looking for full stack engineers and those who lean more towards frontend.

Full stack. You understand applied AI well past the API layer: building systems that stay reliable when the model is unpredictable, writing evals that surface real signal, designing agentic workflows that hold up under production conditions. You've shipped RAG, tool calling, memory, or multi-agent patterns to real users and you know where each one breaks down.

Frontend. You notice things other engineers don't. The easing curve that's slightly off. The transition that happens too fast to register. The empty state that was clearly an afterthought. In a product where AI does most of the heavy lifting, the interface is where trust is built or broken — and you hold that line. You've built design systems from the ground up and have a point of view on motion, interaction, and what makes an AI-generated surface feel considered rather than random.

What we look for

• Production-grade React, NextJS, and TypeScript
• Strong backend experience: async systems, API design, schema decisions, scaling under real load
• For full stack: applied AI in production like RAG, tool calling, memory, multi-agent patterns, and the ability to write evals and reason about whether a system is actually improving
• For frontend: design systems, animation and motion, data-fetching patterns (TanStack Query, tRPC), and deep care for browser fundamentals and performance
• Familiarity with our infrastructure and AI tooling (Cloudflare Workers/Durable Objects, Postgres + PGVector, LangSmith, Inngest) is a plus

What success looks like

Features that are fast, reliable, and polished. Architectural and interaction decisions that make the next thing faster to build. You raise the bar for the people working alongside you.

Application process

Your works speaks louder than your resume. We want to see how you think, what you've made, and how you work with AI. Our application asks for three things:

1. A Loom video (2-3 minutes)

Tell us who you are, what you're working on or have recently built, and how AI is a core part of how you work. Don't script it. We want to see how you think out loud.

2. Something you've built or designed 

A link, a side project, a campaign. Anything that shows what you're capable of making. One strong example beats ten weak ones.

3. A few short questions

1. Why Durable 
2. Where are you located
3. What are your salary expectations

Fine print

We are a Vancouver-based company and candidates need to be based in Canada. Remote is fine - you can expect travel to Vancouver once per quarter (minimum) to work in-office with the team. 

Compensation is $180,000–$225,000 CAD base plus equity, for Vancouver-based candidates. Actual salary takes experience, location, and other factors into account.

What we're looking for

The version of marketing you practice is closer to product development than traditional brand or channel-focused work - small bets, fast feedback, and compounding returns when something clicks. Your opinions come from running real experiments and being willing to kill what doesn't work. You're equally comfortable in an analytics dashboard, an ad account, and a video editor. AI lets you operate at a scale that would otherwise take a much larger team: generating creative at volume, automating analysis, building workflows that run without you.

Right now we're interested in people who are excellent in at least one of the following, and are capable across others.

Paid & performance. You've personally managed meaningful ad spend across Meta, Google, and TikTok. You understand attribution, CAC, LTV, and payback periods in the context of a PLG product. You've owned conversion rate optimization alongside paid because you know the funnel doesn't end at the click.

Growth & CRO. You've worked in product-led environments where activation and retention matter as much as acquisition. You instrument funnels, form clear hypotheses, and run structured tests on onboarding flows, pricing pages, CTAs, and signup forms. You can look at a conversion funnel and immediately articulate where the problem is and what to test first.

AI video & creative production. You've built a content pipeline that runs largely without a production team: brief to script to voiceover to published video. You're fluent in tools like Remotion, ElevenLabs, and all latest video models. You think about creative as a structured, testable variable and produce at volume without sacrificing quality.

What success looks like

• New customers are coming in through channels you built or fixed
• CAC is moving in the right direction and you know why
• You've built things that are working well enough to double down on, and killed some others that aren’t
• We have clearer answers to "where should we be spending?" because of experiments you ran
• Something you shipped is converting measurable better than what existed before.
