Job Description

Join a mission-driven team building the financial infrastructure for family-building. You will develop insurance-backed financing platforms that make IVF accessible and affordable. Working in a small, high-agency engineering team, you will ship features across underwriting, payments, and risk scoring to help real families navigate the financial challenges of fertility treatment.

Benefits

  • Direct human impact: Every feature you ship helps families afford life‑changing fertility treatments that were previously out of reach.
  • High‑growth stability: Backed by top‑tier investors like Atomico and Valar Ventures, Gaia is post‑FCA regulation and successfully expanding into the US market.
  • Engineering agency: Join a small, elite team of eight engineers where you’ll own projects end‑to‑end and significantly influence the technical culture and architecture.

What you will do

  • Design and build scalable software for complex financial processes including insurance underwriting, risk scoring, and payment servicing.
  • Collaborate cross‑functionally with product, design, and data teams to iterate on features using TypeScript, Next.js, and Python.
  • Improve system quality and developer experience by investing in infrastructure, automated testing, and observability using AWS and Vercel.

The Ideal Candidate

  • Over 3 years of full‑stack engineering experience in a fast‑paced startup environment, with a strong leaning towards backend development.
  • Proficiency in modern tech stacks including TypeScript (React/Next.js/Node.js) and Python, with solid experience in PostgreSQL and RDBMS.
  • A pragmatic problem‑solver who prefers simple solutions over complexity and is comfortable navigating the ambiguity of an early‑stage fintech environment.
