  • Relocation and immigration support on a case-by-case basis
  • Design and implementation of different agentic system designs capable of interacting with browsers, operating systems, enterprise filesystems, collaboration tools, etc.
  • Building search and retrieval pipelines across large-scale structured and unstructured data

Requirements

  • Proficiency in Python and a deep understanding of building and debugging complex end-to-end applications
  • Experience working with SaaS environment and production workloads, web interfaces, databases, search engines, and queuing systems
  • Ability to work across the whole stack from web interfaces to control plane and data infrastructure like queuing systems, databases, and search indexes
  • Experience designing or working with secure and virtualized execution environments
  • Build the backend layer for RAG systems and other information context management systems required for agents to operate
  • Familiarity with embeddings, vector databases and large-scale document indexing
  • Background in HCI or interest in building intuitive agent interfaces that extend human capabilities
  • Our research methodology is grounded in methodical, step-by-step approaches to ambitious goals. Both deep research and engineering excellence are equally valued

Skills

  • Experience working with enterprise security and compliance frameworks (i.e., SOC 2, GDPR, etc.)
  • Knowledge of web automation tools and headless browser environments (i.e., Puppeteer, Playwright)
  • Understanding of sandboxed or containerized compute environments with strict access controls
  • Comfort designing user-facing agentic workflows and reasoning systems that span multiple modalities (text, vision, actions)
  • Experience using and fine-tuning models for screen reading, OCR, or UI understanding
  • Machine Learning experience as a double bonus
  • We strongly value new and crazy ideas and are very willing to bet big on new ideas
  • We move as quickly as we can; we aim to minimize the bar to impact as low as possible
  • We all enjoy what we do and love discussing AI

Compensation

  • Competitive compensation and 401(k) plan

Benefits

  • Comprehensive medical, dental, vision, and FSA plans
