Job summary

Thomson Reuters Toronto is seeking a senior engineering leader to design and ship AI agent platforms and production-ready AI systems. You will drive architecture across multiple parallel initiatives, mentor senior engineers, and work with product leadership to translate strategy into concrete designs.

You’ll lead cross-functional efforts to ensure reliability, observability, and safe rollout of AI-enabled capabilities in production, partnering with platform teams across the company.

Qualifications

• Extensive experience architecting and shipping production software systems, including hands-on experience building AI/LLM-powered products or agentic systems.
• Direct experience building with modern LLM APIs, agent frameworks/SDKs, or agent-to-tool integration protocols.
• A track record of setting technical direction across multiple concurrent initiatives, not just delivering one project end-to-end.
• Strong backend engineering fundamentals, including distributed systems design, service architecture, and cloud infrastructure.
• Experience designing for production reliability and observability: monitoring, evaluation pipelines, incident response, and quality regression detection.
• Demonstrated ability to mentor senior engineers and influence technical culture and practices.

Responsibilities

• Set technical architecture and direction across the team's highest-priority initiatives, spanning core agent infrastructure, new internal tooling, and production reliability.
• Provide hands-on technical leadership wherever it matters most, flexing across the team's highest-priority initiatives rather than being locked into a single fixed workstream.
• Architect and build production AI agent systems on top of modern LLM APIs, agent SDKs, and orchestration/runtime infrastructure, designed to scale and integrate cleanly with existing platform services.
• Design agent observability and evaluation practices (tracing, automated evals, and quality/drift detection) so regressions in agent behavior get caught before they reach customers.
• Advance how the team deploys and operates AI agents in production, deepening practices like progressive/feature-flagged rollout and earlier-stage quality signals so releases get both faster and safer over time.
• Drive cross-cutting design reviews and technical decisions (RFCs/ADRs) to keep new systems coherent as multiple initiatives move in parallel.
• Mentor and raise the technical bar for a senior engineering team, including how they use AI-native, agentic development practices to multiply their own output.
• Partner with product and engineering leadership to translate strategic priorities into concrete system architecture and sequencing decisions.
