Why this role is remarkable
- Join a Y Combinator 2024 breakout that is already the UK leader in AI transformation for financial advice, following a major acquisition of a legacy industry giant.
- Work on technically complex infrastructure involving $500bn in assets, where you will define the patterns for high-integrity, event-driven financial systems that do not yet exist.
- Collaborate with a high-calibre engineering team featuring early members from Rippling, Postman, and Gojek in a brand-new five-story office featuring an on-site gym.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
What You Will Do
- Design and own significant backend services and platform capabilities using Go, TypeScript, and Kafka-based event-driven architectures to process high volumes of financial data.
- Architect reliable, long-running workflows that preserve provenance and auditability across complex financial households, products, and regulatory controls.
- Build the critical interfaces and data pipelines that provide reliable, permissioned context to Saturnos.com’s AI platform, enabling automated compliance and investment research.
The ideal candidate
- Brings 5+ years of experience building and operating production backend systems, with deep expertise in Go, TypeScript, or similar languages for distributed environments.
- Demonstrates a strong command of Kafka or equivalent messaging systems, specifically regarding ordering, idempotency, and handling partial failures in mission-critical workflows.
- Has a track record of modeling complex, data-critical systems across SQL/NoSQL and ideally experience in regulated domains like fintech, healthcare, or legal.
