Requirements

  • Have at least 2 years of professional software engineering experience, or an equivalent track record building and shipping real-world systems as a founder, solo builder, or early technical lead.
  • Have hands-on experience building and operating LLM-powered or AI agent systems in production, particularly systems used by real customers.
  • Bring full-stack capabilities spanning backend engineering, infrastructure, frontend development, and AI/agent systems.
  • Demonstrate independent technical decision-making and the ability to choose pragmatic solutions in an early-stage environment.
  • Have experience taking a functional prototype toward production scale through architectural improvements, data modeling, runtime design, orchestration, and reliability work.
  • Have a track record of frequent shipping, iteration based on user feedback, and delivery under tight timelines.
  • Be able to explain the technical challenges, architectural decisions, and tradeoffs involved in systems you have built.
  • Be comfortable with significant ambiguity, limited process, and broad responsibility.
  • Be based in Europe initially and willing to relocate to San Francisco within the first year.
  • Founder or early-stage startup experience is highly valuable; familiarity with recruiting, agencies, professional services, or other service-delivery businesses is a plus.
  • Demonstrate commitment and stability in previous roles; this is preferred.

Responsibilities

  • Design, build, and operate the agent runtime, including orchestration, memory, verification, and multi-agent workflows.
  • Develop backend services, infrastructure, frontend applications, and AI agent systems.
  • Take technical initiatives from design through implementation, deployment, monitoring, and continuous improvement.
  • Establish foundational architecture, engineering standards, development practices, and tooling.
  • Work with the founder to define technical priorities and make product and architecture decisions.
  • Ship product and infrastructure improvements frequently, using customer feedback to guide iteration.
  • Build reliable, maintainable, observable systems that can evolve as the product and customer base grow.
  • Help establish the technical foundation and engineering culture for future team expansion.
