To democratize the cloud for every engineer.
Role
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 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
Desirable
- 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 the job involves
- We're looking for engineers to build all aspects of Neo: from agent orchestration and tool interfaces to the web experience where users watch Neo work, approve operations, and understand its reasoning, to the interface with the models and how we orchestrate and fine-tune them to maximize impact
- We seek bold thinkers to reimagine the entirety of cloud engineering
- 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
Our take
The Infrastructure-as-Code (IaC) space is expanding rapidly, driven by the increasing complexity of cloud services and the growing adoption of cloud technologies by developers and teams who want to reduce operational overhead. Pulumi works to bring together infrastructure, developer, and security teams to help build and operate cloud applications more efficiently.
The service is compativble with all major clouds and programming languages, providing teams with flexibility and reducing silos that can form with other IaC tools. Pulumi has also expanded its platform to include governance and compliance features, testing support, and policy-as-code, creating a more comprehensive cloud engineering solution for modern workloads. And the platform is trusted by over 3,700 customers worldwide, including Snowflake, Nvidia, and the BMW Group.
Building on this foundation, Pulumi recently launched Pulumi Neo, the industry's first AI agent purpose-built for platform engineering. Neo automates infrastructure tasks end-to-end while respecting enterprise governance, allowing teams to provision, deploy, and manage infrastructure faster and more safely. Early adopters report transformative results, including reducing provisioning time from days to hours, deploying features up to 75% faster, and cutting policy violations by 90%. This combination of AI-driven automation, enterprise-grade controls, and aproven customer base puts Pulumi at the forefront of the cloud engineering market.
