Our goal is to leverage technology to increase the value and liquidity of the world’s buildings, while enhancing the productivity and happiness of those that occupy them.

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  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.

• 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

• 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

• 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)

• Partner directly with Product and Research users to understand workflows and translate requirements into technical solutions
