Software Engineering Manager CoCounsel Legal is seeking a Software Engineering Manager to lead the team that owns the Customer Files Orchestration Service- the system that makes a customerdocuments usable by CoCounsel Legal's agents. Every file a customer brings to CoCounsel passes through this team: upload, storage, extraction, embedding, and indexing, orchestrated end-to-end. You make millions of customer files available to CoCounsel.

Bringing a customer's content together with Thomson Reuters' world-class proprietary content and the latest frontier models - including TR's own custom large language models - is what makes our products highly differentiated and our agent experiences genuinely grounded.

Supporting millions of files means real engineering: dedicated workers, fair queuing so one busy customer cannot starve another, durable state, idempotent processing, and honest reasoning about consistency and delivery guarantees across systems. The team owns what it builds, designing, implementing, testing, deploying, scaling, and operating the service end-to-end. This role will help take a recently formed, cross-functional group and shape it into a durable, high-performing engineering team with clear ownership, a stable operational posture, and the credibility to lead decisions about design, roadmaps, and opportunity costs within the team and across stakeholders.

Service & Technical Leadership ~ Own customer file orchestration service end-to-end- Upload, storage, content extraction, embedding, indexing, and observability and monitoring - balancing new capability delivery against reliability. ~ Drive API-first execution-The file and workspace API st this team owns serv a growing set of consumers beyond orchestration, and this team treats them as a product - clear ownership, versioned contracts, documented behavior, deliberate change management, and independentdeployability- not an incidental collection of backend endpoints ~ Lead the team's judgment on the problems that define thedomain- Consistency models (where eventualconsistency is acceptable and where a strongly-consistent read is the only correct answer), delivery guarantees (at-least-once with idempotent processors versus the cost of true exactly-once), lease and heartbeat models for crash recovery, and state transitions across asynchronous service boundaries ~ Own the queuing and flow-control architecture- Fair queuing, rate limiting, backpressure, circuit breaking, dead-letter handling, and autoscaling. ~ Champion full operational ownership- The team designs, builds, tests, deploys, scales, andoperateswhat it ships - with on-call, incident response, SLOs, and testing treated as first-class engineering work, not afterthoughts. ~ Team Management ~ Build and lead the Files Orchestration engineering team- Hiring, onboarding, performance, and career development - turning a recently-formed cross-functional group into a stable team with clear, durable ownership. ~ Develop engineers who combine distributed systems depth with real operational responsibility- Lead an engineering team who ownstheir work from the first line of code to the production dashboard, and who owntesting/QA, deployments, and support rather than handing them off. ~ Translate complex orchestration and scale trade-offs to product managers and business leaders- Making the meaning of a throughput numberand the risk in a deadline legible to non-engineers. ~ Establish operating rhythms andways of working- Establish principledways of working, empowering the team to own their operating rhythms: roadmap, stand-ups, demos, retros, support rotations, and beyond. ~ Strong technical leadership via effective negotiation and influence- Earn the trust of leaders and external teams, negotiating capacity and roadmaps to converge on technical decisions that result in world-class products. Define andmaintainengineeringprocesses- Rigorous design, code review, testing, and instrumentation valuable enough to pro-actively identify and fix issues, provide great support and reliable service. ~ Establish service health benchmarks- Ingest throughput, end-to-end time-to-available, failure and retry rates, per-tenant fairness under load, and API reliability SLOs - used to drive continuous improvement rather than to decorate a dashboard. ~ Sequence foundational infrastructure work against product deadlines- Know when to ship the pragmatic stopgap, when to insist on the structural fix, and how to make the difference visible to leadership.



~ Align the roadmap withCoCounsel's priorities- Collaborate closely with product management and adjacent engineering team to deliver high-quality capabilities and strong technical foundations. Bachelor's or master's degree- Computer Science, Engineering, or related field. ~ Direct people management experience- 8+ years of software engineering experience, including 3+ years of managing engineers.

You have hired, coached, and managed performance, and you want to keep doing it. ~ Large-scale, enterprise orchestration systems- Demonstrated experience designing and operating them in production: pipelines that move large volumes of work through multiple stages, across service boundaries, with retries, partial failure, and long-running steps as the normal case rather than the exception. ~ Extensive AWS and production Python experience- This is a Python service on AWS, and you should be able to engage with the code and the infrastructure credibly. ~ Concurrency in Python, and a healthy respect for how treacherous it is- You understand the GIL and what it does and does not protect you from

- Queues, fair queuing, rate limiting, and backpressure- Deep, practical understanding, including multi-tenant fairness and noisy-neighbor isolation, and the judgment for where flow control belongs in a system. ~ API-first instincts- Versioned contracts, explicit ownership, backward compatibility, and treating an internal API as a product with consumers rather than an implementation detail. Building, owning, and operating a production service end-to-end- You have carried the pager for something and you believe building and operating are inseparable. ~ Communication and alignment- Excellent communication and the ability to build alignment across engineering, product, and architecture, including with people who do not report to you. Documents and document management systems- Extraction, OCR, format handling, very large files, and the integration surface of third- party DMS platforms are relevant. ~ Event-driven architectures and streaming- Kafka/MSK or similar, managed queueing such as SQS, and event-driven autoscaling. ~ Retrieval, embedding, or indexing pipelines- Supporting LLM or agentic applications. ~ Prior exposure to the legal industry- A real bonus, and a meaningful head start on understanding what our customers need from their documents. Understand the pipeline end-to-end- Including the stages owned by other teams, and form your own view of where the real reliability, throughput, and correctness risks sit. ~ Establish strong working relationships- With the architects, principal engineers, and product partners on this work, and with the storage, document understanding, indexing, and connectors teams the service depends on. ~ Own day-to-day delivery and people leadership- Take it off the founding leader's plate, and close out the open hiring needed to make the team whole and reduce dependence on on-loan contract engineers. ~ Deliver a clear, well-reasoned technical roadmap- Covering scale targets beyond the current ceiling, queueing and fairness architecture, API coherence, and the structural fixes currently carried as tolerated mitigations, with buy-in from product and dependent teams. ~ Establish genuine operational ownership- On-call in place, SLOs defined for the service, incident response documented, and a real post-mortem cycle running. ~ Lead the team through a major scale milestone- Well beyond today's per-workspace limit, with the fairness, correctness, and cost characteristics to sustain it, not a number proven once in a test environment. ~ Grow a high-performing team- Where end-to-end ownership, constant shipping, and AI-assisted development are habits rather than aspirations. ~ Establish orchestration as a trusted, measurably reliable service- Well-documented, with an API surface other teams can build on without needing this team in the room. ~ Become a recognized leader within CoCounsel Legal Engineering- Shaping how customer content reaches agents and developing the next generation of senior engineers on the team.
