Build the first experience customers have with a financial platform.

We’re recruiting a Senior Software Engineer for a financial services client’s customer acquisition team.

You’ll work on the journey from someone’s first visit to becoming an active customer: the public website, onboarding, identity verification, sign-in and promotions.

This is a hands-on role with real ownership. You’ll build across the stack, help shape technical decisions and see how your work affects customer experience and growth.

  • What you’ll do
  • Build customer-facing features in React and Type Script, alongside APIs and services in . NET.
  • Improve onboarding, SSO and the systems that determine what information each customer needs to provide.
  • Own features from design discussions through release and ongoing improvement.
  • Work closely with design, product, compliance and other engineers.
  • Keep performance, reliability, accessibility and maintainability front of mind.
  • What you’ll bring
  • Strong full-stack engineering experience, with solid . NET skills and confidence building frontend products in React and Type Script.
  • Experience with relational databases, data-driven rules and headless CMS platforms.
  • An eye for edge cases and a habit of writing clear, testable code.
  • Curiosity about how technical decisions affect conversion and the customer experience.
  • The confidence to take ownership while priorities evolve.

Experience with OAuth/OIDC or SAML, KYC integrations, multilingual websites, technical SEO or high-conversion digital products would be a bonus.

  • The details
  • Location: Sydney, NSW (on-site)
  • Seniority: Mid-Senior level
  • Employment type: Full-time

If you like building polished customer experiences and enjoy solving the engineering challenges behind them, I’d love to hear from you.
