Applied AI Engineer New Toronto

Our mission? To power measurable employee engagement worldwide. And we'd love for you to join us

About the job - Applied AI Engineer Join the Engineering Team, where you'll help build our agentic future.

You will work alongside senior engineers, Product, and our Chief Product & Technology Officer (CPTO) to design, prototype, and ship AI-powered capabilities quickly. This role is hands‑on and iterative, focused on building production‑grade agentic workflows that improve how internal communications are curated, designed, delivered, measured, and orchestrated.

This is an AI engineering role with real infrastructure ownership. You won't be handed a platform - you'll help build the one our AI features run on. If you like being close to both the model and the metal, this is that job.

Our stack, concretely:

Ruby on Rails and Vue.js in a production SaaS codebase; Amazon Bedrock for model inference; AWS on EKS, provisioned with Terraform and Terragrunt across regions; Sidekiq for background work; MySQL and PostgreSQL. We're mid‑migration to a GitOps deployment model with Argo CD and Karpenter. You'll touch most of this.

This is not “call an LLM and hope it works.” It's careful system design, honest measurement, and shipping production systems that people rely on every working day.

This is a great fit if you've shipped LLM features in production, you're comfortable when the answer involves a Terraform plan rather than a prompt tweak, and you're ready to go deeper - with senior engineers around you to learn from.

Your impact Agentic Design & Orchestration:

Build agentic workflows and orchestration patterns (dynamic routing, tool‑using agents, feedback loops) - contributing to the design and owning the implementation of well‑scoped components.

Evals & Measurement:

Own the eval harness for the features you ship. Build the datasets, the automated grading, and the offline regression suites that tell us whether a prompt or model change actually made things better. Raise the bar for evaluation across the team - judge design, offline and online metrics, and the judgment to know when a number is real. Turn production failures into evals that catch that class of failure next time.

Infrastructure for AI:

Own work with SRE and build the infrastructure your features depend on, as code. Build the deployment path for AI workloads on EKS alongside our SRE and platform engineers.

Reliability, Cost & Safety:

Keep our AI layer trustworthy as it grows. Instrument token spend, latency, and failure rates as first‑class metrics. Design for the failure modes that matter - hallucination, timeout, rate limit, cost blowout - and make sure the system degrades gracefully instead of falling over. Respond when things behave unexpectedly in production.

Prompts & Model Configuration as Code:

Treat prompts as versioned, reviewable, rollback‑able artifacts rather than strings someone edited in a console. Own how we move a prompt or model change from idea to production safely, and how we back it out when it turns out worse.

Data Residency & Trust:

We run regional deployments because our customers require it. Help make sure AI features respect those boundaries - that customer data stays in‑region, model invocations are logged, and what we send to a model is what we intended to send. Think about prompt injection and PII exposure before an auditor does.

Execution & Experimentation:

Take a defined problem and run with it. Contribute to our quarterly AI roadmap, run experiments to benchmark model value, and iterate systematically on prompts, retrieval, and model configurations based on what the data tells you.

Cross‑Functional Partnership:

Work closely with Product Management to turn product ideas into concrete technical work - both customer‑facing features and internal workflow automation.

Grow With the Team:

Participate actively in design discussions and code reviews. Ask questions early, accelerate blockers, and share what you learn. Contribute to documentation practices (agents, markdown, Knowledge Bases) as we figure them out together.

Cultural Stewardship:

Be a full participant in helping the engineering culture evolve as we grow.

About you

You hold a Bachelor's degree (or higher) in Computer Science, Statistics, Mathematics, or Engineering, or equivalent practical experience.

3+ years of professional software engineering experience, including hands‑on work with AI/ML or LLM‑powered features.

Strong fullstack experience - Ruby on Rails (or any other backend language/framework) and Vue.js/React (or any other framework) preferred. You're comfortable in a production SaaS codebase and can navigate unfamiliar systems without needing everything explained first.
