Senior Manager, Software Engineering - Search Platform

The CoCounsel Legal Integrations team is seeking a Senior Manager, Software Engineering to lead the engineering team responsible for building, operating, and evolving the shared search platform at Thomson Reuters. This platform is the foundation of TR's search capability – a managed, self‑service infrastructure that allows internal client teams to configure, deploy, and iterate on production search systems in days rather than months, accelerating the delivery of high‑quality search experiences across TR's legal, tax, and professional products.

The team owns what it builds – defining, building, testing, deploying, scaling, and operating search infrastructure end‑to‑end. The Senior Manager is responsible for growing this team from its current early stage into a high‑performing, product‑minded engineering organization that ships to production constantly, treats delivery friction as the first problem worth solving, and holds itself to the same reliability and developer‑experience standards as any best‑in‑class external search platform.

The successful candidate brings deep systems and platform thinking, strong people leadership, and the credibility to make hard architectural calls alongside world‑class engineers and research scientists.

In this position, you will:

• Own the end‑to‑end platform engineering roadmap—spanning document ingestion and processing, search engine management, query APIs, platform control‑plane APIs, and the cloud infrastructure that ties them together—balancing new capability delivery with rigorous management of reliability and technical debt.
• Drive API‑first, self‑service architectural thinking: ensure that every capability the platform delivers is accessible via a clean, versioned, well‑documented API, and that internal client teams can configure and operate search systems without direct involvement from the platform team.
• Lead the migration from current search infrastructure to the platform's strategic search engine, including Vespa adoption, while maintaining zero‑downtime operations on existing production systems throughout the transition.
• Champion full‑stack operational ownership across the team: the team defines, builds, tests, deploys, scales, and operates what it ships—establishing on‑call rotations, incident response practices, SLO definitions, and reliability engineering as first‑class team responsibilities, not afterthoughts.
• Build a team culture where AI‑assisted development is the default and delivery friction is identified and eliminated aggressively—ensuring the team ships to production constantly and that process or tooling obstacles are treated as urgent engineering problems.
• Partner closely with TR Labs to ensure that new retrieval techniques, embedding models, re‑ranking approaches, and agentic search patterns have a clear, well‑supported path from prototype to production within the platform's architecture—including the infrastructure required to serve custom models in production with appropriate latency SLOs, versioning, and rollback capability.
• Oversee platform infrastructure including event streaming (Kafka/MSK), cloud services (AWS), observability tooling, and security controls including multi‑tenant data isolation and customer‑controlled encryption.

• Build and lead a team of approximately 10 software engineers (including Staff and Senior levels), managing hiring, onboarding, performance, and professional development with a focus on cultivating deep technical ownership.
• Develop engineers who bring together distributed systems depth, search domain expertise, and a strong sense of operational responsibility—engineers who own their work from the first line of code to the production dashboard.
• Foster a culture of empowered ownership—where engineers have the autonomy to define the problem, the authority to push back on poor technical decisions, and the accountability to carry work from design through production operations.
• Translate complex platform and search concepts to non‑technical stakeholders—making the value and trade‑offs of…
