The position plays a critical role in establishing foundational platform capabilities, including identity and access management, enterprise data connectivity, telemetry, and production infrastructure, while ensuring solutions are flexible, maintainable, and aligned with enterprise technology standards.

As an early member of the AI Product Group, this individual will collaborate closely with platform leadership, enterprise architects, AI engineers, data platform teams, and globally distributed technical teams to develop production-ready services that enable the firm's expanding AI ecosystem. The role emphasizes strong backend engineering fundamentals, hands-on development, security, evaluation-driven engineering, and end-to-end ownership of production systems. The ideal candidate brings demonstrated experience building and operating shared services, implementing authentication and authorization capabilities, and delivering reliable cloud-based solutions. Prior experience with AI, large language models, or agentic systems is not required; success in this role depends on sound technical judgment, strong problem-solving abilities, and the capacity to quickly learn and apply emerging technologies.

Responsibilities

• Design and Build Shared Platform Services: Develop, implement, and maintain scalable backend services, APIs, and runtime components that support AI agents, enterprise applications, and shared platform capabilities.

• Implement Identity and Access Management: Build secure authentication, authorization, and entitlement capabilities for users, AI agents, delegated agent activities, and autonomous processes, ensuring appropriate access controls and accountability.

• Develop Secure Data Access and Integration Interfaces: Build and maintain APIs, service interfaces, and Model Context Protocol (MCP) endpoints that enable AI agents to securely discover, retrieve, and interact with governed enterprise data.

• Support Flexible and Scalable Platform Architecture: Design reusable services and stable interfaces that enable the firm to integrate, evaluate, and replace AI models, tools, and third-party technologies without disrupting core platform operations.

• Enable Evaluation-Based Development and Release Readiness: Partner with AI Engineering to integrate automated evaluations, testing frameworks, and performance baselines into development and deployment processes, ensuring solutions meet established quality and production standards.

• Drive Platform Innovation and Continuous Improvement: Prototype, test, and evaluate emerging platform capabilities, using measurable results to determine which solutions should be developed into scalable shared services.

• Own Production Deployment and Reliability: Build, deploy, monitor, troubleshoot, and maintain production services, including CI/CD pipelines, automated testing, observability, and operational support to ensure reliable system performance.

• Establish Engineering Standards and Reusable Components: Contribute to platform architecture, technical documentation, shared development patterns, code reviews, and engineering best practices that support consistent and maintainable solutions.

• Support Knowledge Transfer and Technical Ownership: Collaborate with external engineering partners to transition platform capabilities into internally owned, documented, and maintainable production environments, including the development of reusable code, tests, and operational runbooks.

• Collaborate Across Global Engineering Teams: Work closely with AI Engineering, Data & AI Platform, enterprise architecture, security, integration engineering, and engineering teams in India to align technical solutions with organizational standards and business objectives.

• Support Strategic Initiatives: Participate in special projects and perform other duties as assigned to advance the firm's AI platform capabilities and business priorities.
