About the role
Responsibilities
Own the agentic workflow engine: the runtime that executes multi-step, tool-using agent workflows in production
Build and evolve Copilot — our natural language interface for creating, editing, and debugging workflows
Design and maintain integrations with LLM providers (OpenAI, Anthropic, Google, local models via Ollama) and external APIs
Architect the orchestration layer that turns visual flows into reliable, observable agent executions
Set technical standards for the codebase — reliability, testing, code quality, and architecture patterns
Work across the stack in our Next.js monorepo, shipping to production daily
Debug hard problems at the intersection of LLMs, distributed systems, and developer tooling
Requirements
Strong generalist engineer who has shipped complex distributed systems or developer tools to production
Deep experience with TypeScript/JavaScript and Bun; comfort working in a Next.js monorepo
Track record of owning and operating production systems — you've been paged, you've debugged the weird ones, you've made things reliable
Experience integrating with LLMs or building on top of foundation model APIs
High agency and ownership — on a team this small, you define the roadmap as much as you execute it
Strong opinions on architecture, loosely held — you care about building things right but move fast
Backend Engineer building and optimizing core document workflows (viewing, editing, embeds, exports) and greenfield projects in a Django monolith. Requires 3+ years backend experience, strong Python skills, performance optimization, and automated testing.
