Role 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.

Key Responsibilities

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 standards, architecture patterns, and Critical Design Reviews (CDRs)

Collaboration & Communication

• Partner directly with Product and Research users to understand workflows and translate requirements into technical solutions
• Participate actively in agile ceremonies, code reviews, and knowledge-sharing within the team
• Mentor junior engineers on effective AI-augmented development practices, prompt design, and agent usage patterns
• Communicate technical trade-offs and progress clearly to engineering leadership and cross-functional partners

Qualifications

Required

• 8+ years of professional software engineering experience
• Demonstrated proficiency using AI coding tools and agents to develop, test, and ship production software
• Strong ability to review, validate, and debug AI-generated code — you are the quality bar, not the AI tool
• Solid understanding of backend systems, microservice architectures, and distributed systems in Python, Node.js, Java, Go, or C#
• Experience designing and maintaining RESTful or gRPC APIs
• Solid experience with a major cloud platform (AWS, Azure, or GCP)
• Experience with relational databases (PostgreSQL, MySQL) and NoSQL databases (MongoDB, DynamoDB)
• Working knowledge of CI/CD, infrastructure-as-code, and containerization (Terraform, Docker, Kubernetes)
• Strong engineering judgment — knowing when to trust AI output and when to intervene is critical
• Comfort working closely with Product Managers and business stakeholders in a fast iteration cycle

Preferred

• Experience building or deploying LLM-enabled systems, AI agents, or agent orchestration frameworks
• Experience designing evaluation and testing frameworks for AI/agent-generated outputs
• Familiarity with enterprise AI/agent platforms and tool ecosystems
• Experience with data engineering tools and pipelines (e.g., Spark, Airflow, dbt)
• Front-end experience with React, Angular, or Vue.js for internal tools and dashboards
• Experience in Commercial Real Estate, Research, Financial Services, or other data-intensive domains
• Experience modernizing legacy systems or migrating platforms to cloud-native architectures
