Requirements

  • C1 English or equivalent.
  • Deep TypeScript/JavaScript experience with production-grade architecture and opinions on runtime tradeoffs and type safety.
  • Strong AWS experience.
  • Hands-on LLM API experience: function calling, streaming, structured outputs, and prompt engineering.
  • Comfortable leading client calls, demos, and roadmap discussions with founders and VP-level stakeholders.
  • Able to context-switch across multiple client projects and stacks simultaneously.
  • Disciplined process adherence: structured delivery frameworks, PR hygiene, and documentation without being asked.
  • Full dedication required; concurrent formal employment is not compatible with this role.
  • Based anywhere in the Americas, available from 9:00am Eastern time.

Responsibilities

  • Leading client-facing discovery calls, sprint reviews, roadmap discussions, and demos.
  • Evaluating and pressure-testing product decisions before implementation begins.
  • Scoping and delivering work within a structured delivery framework tied to defined business outcomes.
  • Building full-stack in TypeScript/JavaScript across Node, React, and Next.js.
  • Writing and maintaining BDD test suites using Cucumber and Gherkin.
  • Building on the Anthropic API and Claude Code daily including structured outputs, tool use, and agent workflows.
  • Managing client relationships proactively with clear communication and zero surprises.
