About Us

Peratera is a UK-based fintech company, founded in 2022 and authorised by the FCA as an Electronic Money Institution. We are building a modern, all-in-one payment platform that enables businesses to manage global payments and financial operations seamlessly. Our solution allows companies to open multi-currency accounts, send and receive payments worldwide, and manage cross-border transactions from a single platform. Our mission is to simplify global finance and remove friction from international business operations.

Your mission

You’ll drive and support the evolving Technology Vision and newly defined CTO strategy, ensure reliability, correctness and scalability of critical payment flows across the platform by combining exploratory testing with automation-first practices. 

Your Tech Environment

You’ll be working in a modern, scalable tech environment built around Java (Spring Boot) and REST APIs on the backend, with React and PHP powering the frontend. Our infrastructure is hosted on AWS, and the platform is designed as a set of distributed services with multiple external integrations, including payment providers.

We follow an API-first, automation-driven testing approach, leveraging tools like Playwright to ensure high reliability and fast delivery across critical payment flows.

What You’ll Do

Core Quality Ownership 

  • Take ownership of end-to-end quality of payment flows (deposit, payout, reconciliation)  
  • Validate business-critical scenarios, not just features  
  • Identify risks in transaction lifecycle (e.g. callback failures, timeouts)  

Testing and Automation

  • Design and execute API-first test scenarios
  • Build and maintain automated tests (API + selective UI)
  • Develop reusable test components (clients, data builders)  

Integration Testing

  • Test integrations and implement automation integration flow with external providers (Open Banking, payment processors)
  • Validate async flows (callbacks, polling, retries)  

Debugging and Production Support

  • Investigate production issues and reproduce bugs
  • Work with logs, DB and API traces
  • Support root cause analysis  

Collaboration

  • Work closely with backend engineers on testability
  • Define acceptance criteria with product team
  • Contribute to release quality gates  

Continuous Improvement 

  • Help establish regression Testing Strategy  
  • Contribute to CI/CD pipelines (smoke tests, pre-release checks)  
  • Improve overall engineering quality standards 

What We’re Looking For

  • Experience with API testing (REST, JSON, HTTP)  
  • Strong understanding of backend systems  
  • Experience with test automation (Playwright / RestAssured / similar)  
  • Ability to debug issues using logs and databases
  • Understanding of async systems (callbacks, queues, retries)
  • Experience in payments / fintech
  • Experience with CI/CD pipelines  

Nice to Have

  • SQL / data validation skills
  • Experience with distributed systems
  • Prompt engineering for AI-assisted QA and test automation
  • Hands-on experience with AI tools for QA automation

What You’ll Get

  • Competitive, market-aligned compensation
  • Opportunity to work on a high-impact product with real-world scale
  • Modern tech environment and engineering-driven culture
  • International, distributed team with a collaborative mindset
  • Supportive team culture focused on knowledge sharing and ownership
  • Remote-friendly setup with flexible working hour
