- At least 5 years of software engineering experience, with a strong foundation in system design, distributed systems, and maintainable software architecture.
- At least 2 years of hands-on experience building and deploying AI/ML or LLM-powered applications in production.
- Strong proficiency in Python and backend engineering, including REST APIs, asynchronous services, and event-driven systems.
- Hands-on experience with RAG architectures, vector databases, and AI orchestration frameworks such as LangChain, LangGraph, PydanticAI, or AutoGen.
- Experience deploying secure applications on AWS, Azure, or Google Cloud using Infrastructure as Code and CI/CD, alongside observability and AI evaluation tooling.
- Ability to lead client discussions, explain technical tradeoffs clearly, solve problems in ambiguous environments, and own delivery across competing priorities while collaborating with technical and non-technical stakeholders.

- Experience with tools such as Datadog, Grafana, Prometheus, LangSmith, Langfuse, Braintrust, or Weights & Biases.
Responsibilities
- Own client delivery on simpler builds and standard integrations, translating ambiguous needs into clear technical scope, working solutions, and effective handoffs.
- Build production AI applications, including RAG pipelines, custom agents, and multi-step agentic workflows for tax preparation and review, audit testing, workpaper automation, validation, and regulatory analysis.
- Develop scalable, secure, and maintainable backend services using architecture established with Staff and Principal engineers, and partner with Integration Engineers to connect solutions to Thomson Reuters products and client systems.
- Establish AI evaluation, observability, monitoring, tracing, benchmarking, and adversarial testing to improve accuracy, reliability, and production performance.
- Partner with Tax & Audit AI Engineers to translate tax rules and audit procedures into engineering plans, prototypes, and measurable evaluation criteria.
- Manage delivery across multiple engagements at agreed time allocations and contribute technical judgment during discovery, rapid prototyping, and pre-sales discussions.
