About the Company
Hyre AI is partnering with a fast-growing, well-funded fintech startup building critical infrastructure for modern payment systems.
This is a business focused on one of the most pressing challenges in financial services today: helping institutions better understand and assess transactions in real time, reducing fraud, preventing scams, and enabling safer, faster payments without adding friction for genuine users.
Their platform sits at the intersection of data, intelligence, and decisioning; combining real-time analysis, multiple data sources, and adaptive systems to bring greater clarity to complex payment journeys.
They’ve already gained strong traction with major financial institutions and are now scaling both product and engineering. As part of that growth, they’re hiring a Senior Software Engineer to join a high-calibre team working across backend systems, infrastructure, and product.

As a Software Engineer, you’ll play a key role in building and scaling the core systems behind the platform.
This is not a narrow feature delivery role. You’ll be working on backend services, APIs, and infrastructure that power real-time decision-making systems in a high-stakes environment. The work spans backend engineering, cloud infrastructure, and product development; ideal for someone who enjoys solving complex problems with real-world impact.

*
Optimising data storage and query performance across SQL-based systems
*
Improving system reliability, performance, and observability
*
Working closely with product and engineering teams to ship meaningful features quickly
This is the kind of role where you’ll gain strong ownership and exposure to both product and system design.
Required Skills
*
4+ years of professional experience in software engineering
*
Strong experience with Python, particularly in backend development
*
Experience with TypeScript and/or React is beneficial
*
Familiarity with cloud platforms (ideally GCP) and infrastructure as code (Terraform)
*
Solid understanding of relational databases and SQL
*
A proactive, problem-solving mindset and ability to work in fast-moving environments
*
Curiosity, ownership, and a desire to build scalable, well-engineered systems
Nice to Have
*
Experience within fintech, payments, or data-heavy environments
*
Exposure to microservices architecture and containerisation (Docker/Kubernetes)
*
Experience with CI/CD pipelines and testing frameworks
*
Awareness of security best practices in modern software development
Compensation package
*
Equity options
*
Hybrid working (London-based, 3+ days in office)
*
The opportunity to work closely with a high-performing, early-stage team
Why Join
This is a chance to work on a genuinely important problem with real-world impact.
