Principal Software Engineer - Agentic AI (Remote)

About the Role

We’re hiring a Principal Software Engineer - Agentic AI to join our innovative team at Pulumi Corporation. This remote position focuses on building an autonomous infrastructure engineering agent that enhances cloud operations. If you’re excited about agentic AI systems that solve impactful problems for engineers, developers, and security experts, this role is perfect for you.

What You'll Do

• 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 context systems that help Neo understand each customer’s infrastructure patterns and usage.
• Create 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.

Requirements

• Genuine excitement about agentic AI—systems that plan, act, and adapt in the real world.
• Experience building production systems using LLMs, including tool use, function calling, and multi-step orchestration.
• Strong focus on reliability and safety when AI systems take real actions.
• Comfortable across the stack—agent orchestration, backend services, and frontend interfaces.
• Proficient in Python and TypeScript, with the ability to quickly adapt to new environments.
• A product mindset focused on user needs, not just technical interests.
• Excellent communication skills and ability to work well with a distributed team.

Nice to Have

• 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, or retrieval-augmented generation.

What We Offer

• Base salary of $190,000-220,000, including bonuses and equity.
• Comprehensive healthcare coverage for U.S. employees and regionally appropriate coverage internationally.
• Unlimited PTO policy with a requirement of at least three weeks off annually, plus 13 U.S. holidays.
• 401(k) plan with employer match for U.S. employees.
• 20 weeks of paid parental leave for birthing parents or primary caregivers, and 16 weeks for non-birthing parents.
• Fully remote work culture with flexible hours and an annual “work from anywhere” stipend.
• Annual learning and development budget to support employee growth.
• Monthly wellness fund and quarterly happiness fund for team connection.
