Job summary

BMO Financial Group is building an enterprise AI platform. We seek hands‑on Principal/Senior engineers to own core infrastructure that governs how AI runs at scale across AWS and Azure. You’ll operate and harden the platform, ensuring latency budgets, observability, and regulatory evidence in a build‑and‑run model.

You will lead gateway, policy, identity, and registry components, mentoring teammates while delivering enterprise‑grade capabilities with strong security and compliance focus.

Qualifications

• Bachelor's degree in Computer Science, Software Engineering, or a related technical discipline (Master's preferred).
• 8+ years of software/platform engineering experience (Principal), or 5+ years (Senior).
• Experience operating production infrastructure with real SLOs and on‑call ownership, ideally in a regulated industry.
• Depth in API gateways / traffic enforcement; policy‑as‑code; workload identity / zero‑trust; observability pipelines; audit/compliance data platforms.

Responsibilities

• Own capabilities end to end: design, implement, test, ship, and operate production infrastructure.
• Engineer for operability and defensibility from day one: instrumentation, SLOs, latency budgets, failure modes, and runtime evidence built in.
• Build the APIs, SD'able interfaces, and integrations through which domains, DevOps pipelines, and enterprise systems consume platform capabilities.
• Implement policy enforcement, guardrails, identity attestation, and audit as first‑class engineering concerns.
• Ensure every capability produces runtime evidence connecting AI activity to policy enforcement, identity, and lineage for model‑risk and regulatory review.
• Assess emerging AI infrastructure and standards; make cost‑aware engineering choices.
• Mentor and raise the bar: set engineering standards, review designs and code, and grow depth across the team.
• Partner with AI Developer Experience, AI Security and AI SDLC, and Senior AI Architect in platform build and operations.
