Overview As a Senior Engineer on the Research Technology & AI Agents team, you will be a key technical contributor building AI-powered platforms and agents that automate manual research workflows, democratize insights, and enable advanced analytics at global scale. This is not a traditional software engineering role — you will leverage AI coding assistants, enterprise software agents, and LLM-powered development tools as primary instruments for designing, building, testing, and iterating on production systems at speed. You will be expected to deliver high-quality, reliable, and scalable outcomes at speed by orchestrating AI tools and human judgment effectively. This role is intentionally co-located in NYC with Product and Research to enable rapid daily iteration between product vision, technical execution, and real researcher feedback — critical for effective AI agent development and deployment.

AI-Augmented Development & Delivery Leverage AI coding assistants and enterprise software agents to rapidly develop, test, and iterate on production-quality code Own end-to-end delivery of features and systems — from requirements through deployment and monitoring — using AI tools to accelerate every phase of the development lifecycle Apply strong engineering judgment to review, validate, and refine AI-generated code for correctness, security, performance, and maintainability Design and refine effective prompts, workflows, and agent configurations to maximize the quality and reliability of AI-assisted outputs Continuously evaluate and adopt emerging AI development tools and agent platforms available within the enterprise AI Agents & LLM Integration Build and iterate on AI agents that automate research processes and assist with insight generation Implement LLM integrations, agent orchestration, evaluation harnesses, and monitoring pipelines Experiment rapidly with new AI/ML techniques and translate prototypes into production-grade systems Define and enforce quality gates — automated testing, evaluation benchmarks, and guardrails — for agent-driven outputs Platform & Infrastructure Build and maintain cloud-native microservices and scalable APIs consumed by internal products Develop internal tools, libraries, and reusable agent patterns that accelerate team velocity Implement and improve CI/CD pipelines, infrastructure-as-code, and observability tooling Collaborate with data, platform, security, and architecture teams to align with enterprise
