Lead Software Engineer - CoCounsel Legal Desktop App

About the role

Thomson Reuters is looking for a Lead Software Engineer for the CoCounsel Legal Desktop App, a new desktop engineering team. As the founding engineer, you will define the architecture, set engineering standards and ship production code that makes an AI-powered product feel native on Windows and Mac. You will work closely with the Engineering Manager and Product, and mentor the engineers who join you.

Key responsibilities

• Set the technical foundation of the desktop app, including early architecture decisions on framework choice (e.g. Electron, Tauri, native), project structure, IPC patterns, packaging and auto-update infrastructure.
• Write production-quality desktop code for core features such as the main agent experience, local file integrations, OS-level notifications, clipboard handling and system tray presence.
• Integrate with the CoCounsel backend, working with Agent Core and AI Platform teams on agent APIs, streaming responses, file and workspace infrastructure and authentication flows.
• Define and uphold engineering standards: code review practices, unit, integration and end-to-end testing, cross-platform compatibility and performance benchmarks.
• Mentor desktop engineers through code review, pairing and technical guidance.
• Partner with Product and Design, and share desktop patterns with the wider application experience community.

Required profile

• 7+ years of software engineering experience, with significant depth in desktop development for Windows and/or macOS.
• Proven experience leading technical direction on a desktop product, not just executing it.
• Track record shipping high-quality production desktop apps in a professional or enterprise context.
• Ability to mentor engineers and communicate technical trade-offs clearly.

Required skills

• Hands-on experience with a desktop framework such as Electron, Tauri, native Win32/macOS APIs or equivalent.
• Experience integrating desktop apps with cloud APIs, including streaming, OAuth/SSO authentication and local file system access.
• Preferred: greenfield desktop experience, legal tech or productivity software background, AI-powered desktop features, and enterprise deployment patterns (MSI/PKG, MDM).

What we offer

• Flexible hybrid work model.
• Flex My Way policies, including work from anywhere for up to 8 weeks per year.
• Career growth through Grow My Way programming.
• Benefits including flexible vacation, two company-wide Mental Health Days, Headspace access, retirement savings, tuition reimbursement and incentive programs.
• Inclusive culture and two paid volunteer days off annually.
