AI Use in Our Hiring Process

This may include AI-assisted scheduling and candidate communications, and AI-generated interview notes, guides or summaries to help our team focus on the conversation. All hiring decisions are made by our hiring team.

About the Role
This might just be the most interesting internal AI opportunity in Canada (if we do say so ourselves)!

We're hiring a Senior Corporate Engineering & AI Systems Engineer to build the internal platform that lets every Floater scale themselves — so each person feels like a team of ten.

You'll own three things: the  harness  (the secure, governed layer connecting AI models to Float's internal systems, with identity-aware access, tool connectors, guardrails, and audit trails), the  platform  (the paved road that lets any Floater compose, run, and share automations), and the  background agents  (always-on workers that triage queues, reconcile data, and draft responses while Floaters sleep, escalating to a human when judgment is needed).

This is not an evaluate-some-tools-and-write-a-policy role — you'll be in the room when a team describes a problem, and shipping the fix, often the same week.

What You'll Do

Build the harness:  authenticated, scoped, auditable connectors and MCP servers linking LLMs to Slack, Google Workspace, Salesforce, Net Suite, Zendesk, and Float's own product.

Ship background agents that run multi-step workflows end to end  — with the tool routing, memory, retries, human-in-the-loop approvals, and audit trails that make them trustworthy in fintech.

Build the skills-sharing layer  that turns one team's automation into everyone's capability, and drive the adoption that makes it worth building.

Embed with teams to map how they work  and turn ambiguous problems into shipped systems — defining evals before you build and instrumenting reliability and cost as you go.

Own governance with Security and Risk:  non-human identity, scoped permissions, prompt-injection defense, and privacy guardrails that enable rather than block.

About You
You're a builder first — you've seen that the highest-leverage engineering right now multiplies everyone else, and you want to do it somewhere with real ownership and zero red tape.
