Role: Lead Engineer - Agentic Systems (AI/ML focus)
About the Mission:
Be a founding architect of the future of AI-enhanced engineering. We're building a revolutionary agent garden from the ground up—a programmatic, code-first system that will enable 40,000+ engineers to seamlessly integrate AI agents, tools, and data into their workflows.
This is about building the system itself—the connectors, agents, orchestration layer, marketplace infrastructure, and enabling frameworks that will define how engineers interact with agentic AI.
As a Tech Lead you'll be a technical leader shaping the architecture, establishing engineering excellence, and mentoring a team of talented engineers as we create something truly groundbreaking.
What We Offer:
Autonomy: Significant influence over architecture, technology choices, engineering practicesAgile, autonomous teams with management-free delivery, clear roles, and predictability focusModern stack: Latest tools, frameworks, technologies—you'll help choose themWhy This Role is Exceptional:
Define the Future: founding technical leader of a system that will reshape AI-enhanced engineeringGreenfield Opportunity: build new infrastructure with modern technologies while connecting to existing systemsTechnical Leadership: shape technical vision, establish engineering culture, mentor growing teamMassive Scale & Impact: your work will serve 40,000+ engineers across a global organizationInnovation Ecosystem: collaborate with active AI innovation lab and internal AI communityWhat You'll Do:
Architect the Agent Garden:
Design and build core infrastructure for a programmatic (code-first) agent gardenCreate frameworks for agents, commands, hooks, and MCP (Model Context Protocol) connectorsEstablish architectural patterns for agent orchestration, data flow, and system integrationMake critical technical decisions that will shape the system's futureBuild Foundation Components:
Develop robust authentication and authorization systems for multi-system integrationsImplement traceability, auditability, and configurability features enabling safe AI operationsBuild data pipelines that power agent capabilities within the data environmentCreate SDKs and APIs enabling community contributions to the marketplaceLead Technical Excellence:
Define and champion software craftsmanship standards: BDD, DDD, TDD, clean codeEstablish testing strategies and quality gates for a mission-critical systemLead architectural reviews and technical design discussionsSet the bar for code quality, documentation, and engineering rigorDevelop and Enable the Team:
