Key Responsibilities

  • 1

  • 3
    Drive technical decisions and guide fellow engineers on architectural choices

Requirements

  • Solid backend engineering skills with a strong grasp of distributed systems; TypeScript experience is a plus but not required
  • Experience with at least one frontend framework
  • Familiarity with cloud infrastructure, CI/CD pipelines, and observability tooling; you understand how your code runs in production
  • Proven ability to own features end-to-end, from rough problem statement to shipped, maintained product
  • A product and customer mindset: you think about user problems, not just implementation elegance
  • Experience working in cross-functional teams with product managers and designers
  • You actively seek input from your peers and create visibility where it's lacking
  • Comfortable with ambiguity and proactive about asking for what you need to get the job done
  • Excited to leverage AI tools to enhance your impact, including agentic coding
  • You communicate ideas clearly and concisely in written and spoken English
