Senior Software Engineer, Full-Stack

Cash Forecasting is our AI-amplified treasury solution that helps CFOs and treasury teams move beyond error-prone spreadsheets to achieve real-time cash visibility and predictive accuracy.

The platform integrates seamlessly with major ERPs and banking systems to automatically capture, categorise, and analyse transactional data across multiple currencies and business units. Leveraging our proprietary GSmart AI technology, the solution continuously learns from historical cash flows, sales data, and treasury information to automatically select optimal forecasting algorithms and improve accuracy by over 30%.

You'll work on sophisticated Ruby on Rails and React software that turns diverse financial data into clear analysis, giving customers sharp insight and forecasting through intuitive dashboards. This is a critical platform moving over $100 billion in daily cash flow for enterprise customers across 40+ countries, built to hold enterprise-grade security and scalability at that scale, every single day.

Own the data layer, schema design, query performance, and data integrity - with a strong emphasis on PostgreSQL and SQL more broadly

Write and maintain thorough test coverage using RSpec, treating testing as a first-class part of delivery

Package and deploy services using Docker, and work within our AWS-based cloud infrastructure

Write scripts and tooling to automate repetitive work, support data migrations, and keep the team moving quickly

Instrument the systems you build with strong observability practices -logging, metrics, and tracing — to catch and resolve issues before they impact customers

Benchmark and profile code to identify performance bottlenecks, and make evidence-based decisions about where to optimise
