The client is one of the largest job search and recruitment platforms in the world, with over 35 million job listings across 78 countries and tens of millions of unique monthly visitors. Our mission is to centralize all jobs available on the web — from company career sites, staffing agencies, and job boards — into a single, seamless experience for job seekers and employers.
Headquartered in Montreal with a global team across North America, South America, and Europe, we’re investing in a new generation of AI-native products that will redefine how people find work and how employers find talent.
What project we have for you
It is one of those products. Product is the workforce-intelligence layer for high-volume hiring. It’s how the company is going from job platform to AI-native software company.
You’ll join the Product team — a small, focused team operating as a startup inside the company. Same speed and autonomy as seed-stage. Distribution, data, and customer relationships of a 15-year-old platform underneath. Team will work directly with the VP of Product, CPTO, and design-partner customers across healthcare, retail, residential manufacturing, BPO/contact center, and education.
What you will do
- An Engineer at a venture-backed startup. You’ve felt what it’s like to operate without a playbook.
- Shipped agentic LLM systems to paying enterprise customers — not prototypes, not internal demos. Real users, real workflows, real escalation paths.
- Made the “rewrite vs. keep” call on someone else’s in-flight codebase — and were right about it.
- Cleared a regulated procurement gate in production — security review, bias audit, compliance certification, or equivalent.
- Full-stack capable. You move comfortably across backend, frontend, and infra; you know when to specialize and when to glue things together.
What you need for this
- Execute engineering for our AI-native product — own your technical direction end-to-end.
- Build and integrate AI capabilities deeply into the product, including LLM-based generation, agentic workflows, evals, and the infrastructure that supports them in production.
- Ship fast. Take features from rough idea to in front of users with strong instincts for what to build, what to cut, and what to defer.
- Contribute to the foundational technical decisions — model selection, evaluation frameworks, data and inference pipelines, observability, and the trade-offs between latency, cost, and quality.
- Build the eval and observability layer that makes agentic decisions defensible to customer security, procurement, and legal teams.
- Sit in customer calls weekly. Translate customer signal directly into product.
Will be a plus:
- Experience with Python.
- Experience with Temporal (or comparable workflow orchestration platforms).
- Direct production experience with Anthropic, OpenAI, or other major model providers — including migrating between them.
- Built evals customers actually trust, not vanity dashboards.
- Background contributing to or shipping AI-native products in regulated industries (healthcare, financial services, hiring).
- Open source contributions or technical writing in the AI / ML space.
