About the Job

Requirements

  • At least 5 years of hands-on experience as a software engineer, machine learning engineer, applied artificial intelligence engineer, forward-deployed engineer, or similar, with strong Python skills.
  • Ability to earn credibility with both AI infrastructure engineers and machine learning/artificial intelligence engineers.
  • Hands-on experience building large language model applications and agents with tool calling, MCP, retrieval, memory, and evaluation, using frameworks such as LangGraph, LlamaIndex, CrewAI, Pydantic AI, or the OpenAI Agents SDK.
  • Experience working with cloud computing platforms such as AWS, GCP, or Azure, or managed AI solutions, and a foundational understanding of cloud infrastructure concepts.
  • Working knowledge of model serving, including OpenAI-compatible APIs, open-weight models, and serving engines such as vLLM or SGLang, and ability to explain cost and latency tradeoffs.
  • Evidence of sharing technical work publicly through GitHub repositories, open-source contributions, blog posts, videos, talks, or an active technical presence on social platforms; applicants should include links.
  • Strong written and verbal technical communication skills, including technical documentation, white papers, video explainers, and presentation decks.
  • Ability to travel up to 20%.
  • Bachelor's, Master's, or PhD degree in Computer Science, or equivalent practical experience.

Responsibilities

  • Architect and ship end-to-end reference agents and starter kits on Crusoe covering tool use, MCP, multi-agent orchestration, retrieval-augmented generation, structured outputs, memory, and evaluations.
  • Own code examples, tutorials, and documentation that help developers progress from their first API call to a working agent, and keep them tested and up to date.
  • Own Crusoe's developer-facing GitHub presence, including examples, cookbooks, and integrations.
  • Contribute upstream to agent frameworks, inference engines, and developer tooling, including LangGraph, LlamaIndex, CrewAI, Pydantic AI, the OpenAI Agents SDK, MCP, vLLM, and SGLang, to ensure they work well with Crusoe.
  • Create deep-dive blog posts, notebooks, YouTube videos, livestreams, and short technical clips based on systems built for developers.
  • Share work publicly on platforms including X, LinkedIn, YouTube, Discord, Reddit, and Hacker News; answer technical questions, review community projects, and build credibility in agent and open-source communities.
  • Partner with GTM/Solutions Engineering to identify recurring customer patterns and create open reference architectures for developer segments such as Physical AI, robotics, simulation, and other industry verticals.
  • Join Product, Engineering, and Research workflows; test features and models before launch, prepare samples and documentation for launch day, and provide concrete product feedback on developer friction, following each issue until fixed or deprioritized.
  • Give technical talks, live demos, and hands-on labs at conferences, meetups, hackathons, and workshops.
  • Build agentic AI systems and demonstrate how they work to other developers.

Desired Qualifications

  • Maintainer or significant contributor to an open-source AI, agent, or inference project.
  • Experience producing technical video content such as YouTube tutorials, livestreams, or screencasts.
  • Experience fine-tuning or post-training open-weight models using supervised fine-tuning, reinforcement learning, or LoRA.
  • An existing technical audience that trusts the candidate's views on models, agents, and tooling.

About the Company

Crusoe

Builds AI data centers near cheap energy

Crusoe builds and runs data centers for artificial intelligence, placing them near cheap or otherwise wasted energy and handling everything from the power supply to the cloud software. It developed the flagship campus in Abilene, Texas, for Stargate, the AI infrastructure project backed by OpenAI and Oracle. AI companies rent its GPU servers on demand or under longer contracts through Crusoe Cloud to train and run their models, while larger customers lease entire campuses that Crusoe develops and operates for them. The company was founded in 2018, when it began running computers at oil fields on natural gas that would otherwise have been burned off, and it is based in Denver.
