Responsibilities

• Architect and hands-on build the core of the AI Platform: the MCP gateway, AI portal and skills marketplace, identity brokering layer, and agentic execution flows that the rest of engineering builds on

• Design secure-by-default integrations between internal systems and AI agents, with proper authentication, authorization, RBAC, and audit logging
• Build the telemetry and observability that make AI usage and spec-driven development measurable across the organization
• Partner with engineering teams across the firm to turn their workflows into reusable skills, MCP servers, and agentic routines
• Establish patterns, guardrails, and golden paths so teams can adopt AI tooling quickly, safely, and within governance standards
• Champion best practices in software development, testing, and deployment, and ensure the scalability, reliability, and performance of platform services in a Kubernetes and DevOps environment
• Continuously evaluate emerging models, frameworks, and agent patterns and fold the useful ones into the platform

Skills

• Bachelor's degree or equivalent work experience
• Minimum 7 years of relevant software engineering experience
• Demonstrated experience designing and building platform, infrastructure, or backend services used by other engineering teams

• Familiarity with scripting and automation (e.g., Bash, PowerShell) and with CI/CD pipelines and infrastructure as code (e.g., GitLab CI, Helm)
• Comfort operating in ambiguity and an enthusiastic willingness to creatively solve problems for which there is no pre-existing blueprint
• Excellent communication skills and the ability to influence and collaborate with engineers across diverse teams
• Embraces AI as a core part of the daily workflow and a partner in problem-solving
• Hands-on experience building LLM-powered or agentic applications (MCP servers, tool-calling agents, retrieval / RAG)
