Founding Full-Stack Engineer

airyhr is building an AI-native HR company for Southeast Asia. The conversation is the product: a business owner types one sentence in chat, and hiring, payroll and compliance get executed. Airy does the HR work. You make the decisions. What you'll do: As the first full-time engineer, take the product from the first line of code to serving real paying clients — our first 100+ headcount client is signed and goes live this month. A senior CTO (ex-tier-1 fintech engineering lead) works closely with you every week: he sets direction, you own the build. Deliver, and the Deputy CTO seat within 12 months is a real path, not a slogan. Only four requirements: You have independently shipped at least one 0→1 product — from empty repo to real users. Come prepared to walk through that one build in depth: which decisions were yours, and what you cut.You can turn complex technical work into half a page a non-technical founder understands. Written communication is the lifeline of this role.You buy into one engineering iron rule: money calculations are 100% deterministic; LLMs only translate and explain — they never enter the ledger.Chinese is the primary working language (team and clients operate in Chinese); you can read and write technical documents in English. We hire for traits, not years: a strong three years beats a mediocre five. Compensation: SGD 8–10k/month + early core-team equity with a defined growth mechanism. To apply: Send your CV plus a one-paragraph answer to "Why can't payroll be calculated directly by an LLM?" to [alex@airyhr.com]. There is no single right answer, but there are disqualifying ones.
