About this role
Role Overview
- Legacy Modernisation: Read legacy code (PHP, Perl, or JavaScript), extract the business logic, and reimplement it correctly within a modern microservices architecture.
- Reliability First: Ensure idempotency, data integrity, and graceful error handling across all services — "almost working" is never good enough.
- Greenfield & Refactoring: Split your time between building new features from scratch and refactoring existing legacy modules into clean, maintainable code.
- API Engineering: Design and consume external APIs with a deep understanding of webhooks, callbacks, and complex retry policies.
- Agile Collaboration: Maintain clean and strong English communication to effectively collaborate with multiple stakeholders across departments working in agile sprints.
- Product Thinking: Go beyond the "what" and "how" of the code — bring a product-focused mindset to understand the business logic and end-user impact of what you build.
- Infrastructure Contribution: Contribute to CI/CD pipelines, Docker, or Kubernetes infrastructure where relevant. If you have a passion for infra, you are more than welcome to bring it.
- Innovation: Propose and advocate for tools or technologies that can demonstrably improve our performance, security, or development speed.
Requirements
- Python Mastery: 5+ years of backend engineering experience with strong Python expertise. Deep AsyncIO proficiency — you must be comfortable building non-blocking, high-reliability microservices.
- Framework Expertise: Production-grade experience with FastAPI (not just familiarity).
- Databases: Experience with MySQL and/or PostgreSQL — query design, schema understanding, and migration strategies.
- Testing Discipline: Experience writing unit and integration tests (pytest preferred).
- API & Reliability Patterns: Expertise in designing and consuming external APIs with a deep understanding of webhooks, callbacks, and complex retry policies.
- Ownership Mindset: Willingness to take full ownership of high-traffic, always-up applications and operate independently within an established architectural vision.
- Confidence in Complex Systems: Comfortable in complex distributed environments where reliability is non-negotiable.
- Clean & Intentional Code: We value deep engineering logic over AI-generated snippets. You must be able to explain the reasoning behind every line you ship.
- Curiosity for Product: You care about the "why" behind a feature — how it works for the end-user and what it means for the business.
- Strong English: Both written and verbal to collaborate effectively across multi-functional teams.
- Nice to Have: Experience with PHP, Perl, or JavaScript — a strong bonus signal for legacy comprehension.
- Kafka / Redis experience.
- Docker / CI/CD / Kubernetes familiarity.
- Financial industry exposure — fintech, payments, 3DS, Token Management Systems, or payment gateway integrations.
- Track record of successfully migrating systems from one language or paradigm to another.
