You will not wait for every decision to be translated into a detailed specification. You will use customer evidence, product data and technical judgement to make trade-offs and move work forward.
You will also contribute to the frontend architecture and shared foundations that allow Saturn’s client-facing products to remain coherent as the company scales.
Your work will help determine whether Saturn becomes a collection of capable tools or a coherent product advisers rely on to run their working day.
Our engineers care deeply about craft, speed and quality. They include early and founding team members from companies including Rippling, Postman, Gojek, CRED and Slice.
You will work alongside product designers, backend engineers, AI engineers and domain experts with decades of experience in financial advice and compliance.
We are building a small, high-calibre engineering organisation for people who want genuine ownership, difficult product problems and the opportunity to shape an important company while its foundations are still being formed.
Our values
We hire people who pursue greatness, care deeply about their work, seek truth over comfort, earn trust rather than assume it, and succeed or fail as one team.
