Role: AI Agent Developer
About the Mission:
Join us in building the future of AI-enhanced engineering. We're creating a revolutionary agent garden from the ground up—a programmatic system that will enable 40,000+ engineers to seamlessly work with AI agents, tools, and data.
As an Agent Garden Developer, you'll work on the core infrastructure that powers this system: building agents, creating connectors, implementing orchestration logic, and enabling the marketplace where engineers discover and contribute to AI services.
This is a unique opportunity to work at the cutting edge of AI and software engineering, learn from experienced tech leads, and contribute to a system that will have massive real-world impact.
What We Offer:
Mentorship program: Learn from experienced tech leads and principal engineersGrowth opportunities: Clear development path with support for advancing your skillsAgile, autonomous teams with management-free delivery, clear roles, and predictability focusModern tech stack: Work with latest AI/ML technologies, frameworks, and toolsWhy This Role is Exciting:
Work with Cutting-Edge AI: get hands-on experience building agentic AI systemsLearn from Experts: work alongside tech leads and principal engineers who will mentor youMassive Impact: your code will power a system used by 40,000+ engineersGreenfield Project: build new infrastructure with modern technologies while connecting to existing systemsCareer Growth: clear path to senior roles with mentorship, challenging projects, opportunities to leadWhat You'll Do:
Build Agent Infrastructure:
Develop agents, MCP (Model Context Protocol) connectors and moreBuild frameworks making it easy for others to create and deploy agentsContribute to the programmatic (code-first) system architectureIntegrate AI with Engineering Tools:
Work with AI/ML APIs (OpenAI, Anthropic, or similar) to build intelligent featuresImplement prompt engineering patterns and interaction flowsConnect AI capabilities with engineering tools (e.g., GitLab, Polarion, data sources)Build authentication and authorization for secure multi-system integrationWrite High-Quality Code:
Follow software craftsmanship principles: TDD, clean code, living documentationWrite unit and integration tests for your componentsParticipate in code reviews and learn from senior engineersDocument your work to help others build upon itGrow Your Skills:
