  • Collaborate on core platform features, including a real-time, multi-user IDE for AI workflow development and orchestration.
  • Design and implement complex workflows for AI agents, integrating multiple LLM APIs (e.g., OpenAI, Anthropic, Mistral).
  • Work with cloud technologies like AWS/Cloudflare to ensure scalability, reliability, and performance.
  • Solve challenging engineering problems: Develop an executor for AI workflows that balances real-time performance with traceability, low latency, and scalability.
  • Optimize the user experience for both technical and non-technical users by integrating multimodal tools and creating seamless workflows.
  • Collaborate closely with users: Gather feedback, troubleshoot issues, and iterate to improve the product.
  • Contribute to product decisions and evolve the platform to meet the needs of our diverse user base.

Ideal Candidate

We're looking for a full-stack engineer who:

  • Has 4+ years of experience building production-ready software.
  • Proficient in TypeScript, Next.js, React, and modern JavaScript/TypeScript frameworks.
  • Experienced in backend development (Node.js, serverless architecture, APIs).
  • Comfortable with cloud technologies (AWS, Cloudflare, etc.) and understands scalability challenges.
  • Has experience working with LLM APIs (OpenAI, Anthropic, Mistral) and/or AI development.
  • Thrives in startup environments and is able to take ownership of projects and deliver results quickly.
  • Passionate about creating products that impact users and solving complex problems with scalable, maintainable code.

Bonus Points for:

  • Previous founder or CTO experience in a tech startup.
  • Familiarity with real-time collaborative tools (e.g., Y.js) and multi-agent systems.
  • Experience in AI development or AI tooling.

Why Join This Startup?

  • High-impact role: Help define the future of AI development and be a key player in a growing industry.
  • Early-stage influence: Shape the product, culture, and strategic direction of the company.
  • Competitive salary ($150,000 - $250,000) and equity in a rapidly growing startup.
  • Work in a dynamic, startup-first culture-we believe in getting things done and having fun along the way.
  • Office just 30m from the ocean-yes, there's a sauna and crossbow competitions.
