Maple’s purpose is to meet the world's healthcare needs. We’re Canada's leading on-demand healthcare platform, connecting patients with Canadian-licensed doctors, nurse practitioners and specialists. Today, we’re proud that over 8 million patients and 7,000 businesses and government partners have access to same-day, proactive and ongoing care. We enable people to take control of their health and push the boundaries of what’s possible every day.
Bold minds. Big impact. A career at Maple is about making an impact. We empower bold thinking, surround you with an inspiring team and are driven by a motivating purpose. Here, you’ll do work that changes lives—including your own.
The role
We're looking for a Staff AI Engineer to help our engineering teams build, evaluate, and scale AI features across the product — and set the bar for what great looks like.
In this role, you'll design the evaluation, safety, and agent execution patterns that every squad builds to, stay hands-on with reference implementations and evaluation harnesses, and coach engineers across the org so squads can ship AI features safely and confidently. You'll work closely with Product Engineering, Platform Engineering, Product and our Security, Privacy, and Clinical partners — turning a fast-moving, regulated healthcare environment into a place where AI can scale with the quality patients and providers deserve.
Your responsibilities
Set the guardrails, evaluation strategy, and observability standards that keep AI feature quality, safety, and technical health high across the product
Shape the model and provider strategy, usage patterns, and cost controls that keep AI unit economics healthy as we scale
Define the evaluation strategy, agent execution architecture, and reference patterns that the teams building and maintaining AI features build to
Mentor and coach squads and engineers across the org so they can safely do more of the AI work themselves, against Maple's standards
Partner with Product and Engineering squads on agentic feature development as a senior technical partner and reviewer
Co-define the AI governance model with Security, Privacy, Legal, and Clinical partners — including review criteria, PHI handling expectations, and escalation paths
Translate technical AI choices — cost, clinician efficiency, patient experience, and risk — into clear business outcomes for executive and cross-functional audiences
As a Staff AI Engineer, you will:
What success looks like
Over your first 12–18 months, you'll roll out a company-wide agent execution architecture adopted by the majority of squads shipping AI features, stand up production-grade monitoring for quality, safety, cost, and latency with clear SLOs, and deliver measurable AI cost optimization against your v1 baseline. Every customer-facing AI feature will be covered by an approved evaluation harness and monitoring dashboard, and squads will be independently shipping AI features to Maple's standards
What you bring
8+ years of software engineering experience, with 2+ years in a Staff or Principal-level applied AI or ML engineering role
Demonstrated ownership of agentic or LLM-powered systems in production — including evaluation, guardrails, and cost and latency tuning at scale
A strong track record designing evaluation strategies for non-deterministic systems — offline evals, online evals, human-in-the-loop, regression harnesses
Deep understanding of agent execution patterns (tool use, planning, memory, orchestration frameworks) and their trade-offs
Experience defining AI quality and monitoring practices — quality metrics, hallucination and safety controls, drift detection, incident response
A builder's mindset — a product engineer with deep empathy for user and customer impact, comfortable getting hands-on with code, prototypes, and reference implementations
Proven ability to influence — mentoring senior engineers, setting standards across squads, and partnering with platform teams
Excellent written and verbal communication; you can translate confidently between executives, product, clinical and compliance stakeholders, and deep technical teams
Play to your strengths. Finding the right fit goes both ways—so this section is yours to complete. When you join, you'll add the unique strengths you bring that aren't captured above.
