Senior Software Engineer

Who you are

• Are genuinely excited about agentic AI—systems that plan, act, and adapt in the real world, not just generate text
• Have built production systems using LLMs, including experience with skill design, tool use, function calling, and multi-step
• Orchestration
• Care deeply about reliability and safety when AI systems take real actions with real consequences
• Are comfortable across the stack—agent orchestration, backend services, and frontend interfaces
• Have strong Python and TypeScript skills (our primary languages) and can pick up new environments quickly
• Bring a product mindset: you think about what users need, not just what's technically interesting
• Communicate clearly and work well with a distributed team
• Experience with cloud infrastructure (AWS, Azure, GCP) or infrastructure-as-code tools
• Background in building developer tools, CLIs, or platform engineering systems
• Familiarity with container orchestration (Kubernetes, Docker)
• Experience building evaluation frameworks and benchmarks for AI systems
• Knowledge of prompt engineering, fine-tuning, MCP, or retrieval-augmented generation

What the job involves

• Build the planning and execution systems that let Neo safely perform multi-step infrastructure operations across AWS, Azure, GCP, Kubernetes, and more
• Design tool interfaces that give the agent semantic understanding of cloud resources and access to engineering workflows
• Develop the context systems that help Neo understand each customer's infrastructure patterns and usage
• Create the feedback loops and self-correction mechanisms that make autonomous operation reliable
• Build evaluation frameworks to measure agent performance across Neo's capability areas: migrations, compliance, cost optimization, diagnostics, and more
• Work on the web interface where Neo operates as a "virtual teammate"—task assignment, progress visibility, approval workflows
• Integrate Neo's capabilities into Pulumi's MCP Server for agent-to-agent workflows
• Collaborate with platform teams to deeply integrate agent capabilities into the CLI, SDKs, and Pulumi Cloud
