- Build reusable AI components, frameworks, and solution templates that scale delivery across the team.
- Set standards for MLOps/LLMOps, Infrastructure as Code, and CI/CD so delivery is secure, repeatable, and fast.
- Identify weaknesses in existing designs and drive remedies.
Quality, Observability, and Trust- Set the strategy for AI monitoring and observability, covering performance, output quality, latency, cost, and production reliability risk.
- Own LLM evaluation, including accuracy, hallucination risk, citation quality, A/B testing, and red-teaming, and define quality benchmarks grounded in real legal workflows.
- Ensure every solution meets ethical AI, data protection, and enterprise security requirements.
- Drive operational excellence across the software development lifecycle, including post-launch measurement.
Client and Stakeholder Engagement- Act as the senior technical voice in discovery on high-value engagements, scoping use cases, shaping architectures, and building credibility with legal and technical executives.
- Present complex technical concepts and strategy to audiences from engineers to business unit executives, and negotiate solutions between key stakeholders.
- Work with legal SMEs to translate professional reasoning and domain heuristics into pipeline design, evaluation criteria, and benchmarks.
- Anticipate customer and market needs and feed field insights back into the product roadmap.
Leadership, Mentorship, and Culture- Mentor and coach Staff, Senior, and Lead engineers, and indirectly lead a small team of engineers and technical experts on ambiguous problems.
- Review architecture and design at team and sub-unit levels and give authoritative feedback.
- Strengthen engineering culture through knowledge sharing and by championing AI-native tools and practices.
- Work with program and project managers to bring the technical dimension into status and risk reporting, and consult on budgets for large programs where applicable.
- Represent Thomson Reuters externally through speaking, publications, community engagement, or open-source and standards participation.
Required Qualifications- 12+ years of software engineering experience, with deep expertise in system design, distributed systems, and architecture, and a track record of leading highly complex, high-risk projects.

- Expert Python (FastAPI or equivalent), with strong experience in RESTful, async, and event-driven architectures.
- Experience with a major cloud platform (AWS, Azure, or Google Cloud Platform) and Infrastructure as Code (Terraform, CDK, or equivalent).
- Production observability experience (Datadog, Grafana, Prometheus, or similar) and experience with AI evaluation platforms (LangSmith, Langfuse, Braintrust, or W&B).

- Demonstrated fluency with AI-assisted development tools (Claude Code, Cursor, GitHub Copilot) and a track record of driving AI-native engineering practices.
- Proven ability to influence across teams and domains, advise senior leadership, and communicate complex ideas at multiple levels of an organization.
