Job Description

Founding Engineer

Tsenta (YC S26)

• Build core product across the full stack — the job-matching engine, resume tailoring, the ATS auto-fill system, and the agent surfaces (web app, Chrome extension, iMessage/WhatsApp, and MCP server). • Reverse-engineer and reliably automate 19+ applicant tracking systems at scale, handling logins, every field type, and open-ended questions. • Ship LLM-powered features that read job descriptions, tailor application materials, and answer open-ended questions in each candidate's voice — accurately and within ATS constraints. • Own features end to end — from design and architecture through deploy, monitoring, and iteration. • Set the engineering culture and standards as one of the first hires, and help us recruit the rest of the team.

Job Requirements

  • 3+ years building and shipping production software, ideally at an early-stage startup or in a role with broad ownership.
  • Strong full-stack ability — comfortable owning everything from the database to the UI, and biased toward shipping.
  • Experience with web automation, scraping, or browser tooling — or the appetite to go deep on it fast.
  • Hands-on experience building with LLMs and turning them into reliable, production-grade features.
  • High autonomy and ownership — you scope ambiguous problems, make calls, and drive them to done.
  • Excited to work in person, move fast, and help shape an early-stage company.

Benefits

  • Meaningful founding-level equity
  • Competitive salary
