We are expanding our engineering capabilities and looking for a Senior Backend Developer to join our Core Gateway team. This is a unique, dual-track role where you will play a central part in both the present and future of our infrastructure. You will support, maintain, and extend our existing Perl-based payment gateway ensuring stability and high performance in a live financial production environment while simultaneously leading the architecting and building of our next-generation Python microservices platform.
In this role, you will work in a fast-paced environment where system performance, scalability, and 99.9% reliability are critical to our core transaction flow.

- Integrations: Integrate third-party APIs and external payment services into both legacy and modern platform layers.
- 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 user impact of what you build.
- Engineering Standards: Participate in code reviews, uphold high code quality standards, and contribute to a culture of continuous improvement.
- Infrastructure: Work closely with DevOps on CI/CD pipelines, containerization, and cloud deployments.
What we need:
- Python Expertise: 5+ years of backend engineering experience with strong Python mastery (AsyncIO and FastAPI preferred).
