Senior Software Engineer, Search Platform

About this role

Senior Software Engineer, Search Platform

Our vision

We are building the next-generation search platform, with a vision to democratize knowledge construction and consumption at Thomson Reuters. The platform consolidates search systems across Thomson Reuters products and services, serving millions of end users, internal agents, and internal search teams, into a fully managed, customizable, sovereign, and self-serve search platform.

Job Description

The AI Enabled Software Engineering (AIESE) team within Thomson Reuters is seeking Senior Software Engineers to build the core of that platform: the ingestion pipelines that turn content into searchable knowledge, the APIs that serve it to products and AI agents, and the cloud infrastructure that keeps it fast and reliable. Your work is what lets internal teams create, configure, and run search on their own, without waiting on a central team.

This is a full-ownership role. You design, build, test, deploy, and operate production systems at scale. We ship to production constantly, treat delivery friction as an engineering problem to solve, and use AI-assisted development as a primary tool. Senior Engineers here hold design authority within their scope, share expertise across the team, and mentor more junior engineers.

Key Responsibilities:

Build the platform

• Design, build, and test platform services across document ingestion, search indexing, and query APIs, using the language best suited to the problem (for example Python, Java, or Go).

• Build reliable pipeline components that move documents through parsing, chunking, enrichment, and indexing, using proven patterns for retries, dead-letter queues, and idempotent processing.

• Build self-service platform APIs that let client teams configure search systems, manage index lifecycles, and monitor ingestion health.

• Design retrieval interfaces for products and AI agents with predictable contracts, explicit latency budgets, and result payl...
