Senior Software Engineer, Agentic AI - Pulumi

About Pulumi

Pulumi is reimagining how teams build cloud software, enabling developers and infrastructure experts to work better together through a unique combination of programming languages, tools, and systems innovation. Our flagship infrastructure as code technology is open source and our SaaS product, Pulumi Cloud, provides platform teams, secrets management, and cloud management capabilities, and more.

We're building an autonomous infrastructure engineering agent: think Claude Code, but for your cloud. Neo is Pulumi's answer to what infrastructure engineering looks like in an AI-first era. It's a virtual infrastructure teammate that understands your cloud environment, plans and executes multi-step operations, and brings domain expertise to problems ranging from complex ML infrastructures to cloud migrations and continuous compliance enforcement.

While Pulumi is headquartered in Seattle, WA, we are dedicated to being a remote-first company. This role will be located remotely within the U.S., with a preference for candidates based in Pacific Time Zone locations.

Responsibilities

• 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.

You may be a good fit if you:

• 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.

Strong candidates may also 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, MCP, or retrieval-augmented generation.

• Base Salary Range: $185,000 to $215,000
• Healthcare Coverage: Comprehensive medical, dental, vision, and supplemental insurance at no cost to U.S. employees.
• Time Off: Unlimited PTO policy with a minimum requirement of three weeks off annually, plus 13 U.S. holidays.
• 401(k): Eligible for a 401(k) plan with an employer match.
• Parental Leave: 20 weeks of paid leave for birthing parents or primary caregivers, and 16 weeks for non-birthing parents.
• Remote-First Culture: Asynchronous collaboration, annual “work from anywhere” stipend, and teammates across 20+ U.S. states.
• Professional Development: Annual learning and development budget.
• Equity Ownership: Equity included in all full-time employee offers.
