What we're looking for

We are seeking a talented, endlessly curious individual to join our team. You’ll be working closely with our group of companies in the fintech sector as part of the Engineering department. This company is a leading B2B fintech platform in its field, processing over US$2B across multiple currencies annually. We’re looking for individuals who are driven to create meaningful value, take full ownership of what they build, and thrive in a fast-paced, high-growth environment. If you’re motivated by impactful work and eager to be part of an innovative team, we’d love to hear from you.

What you’ll do

• Design, develop, and maintain scalable backend services using Go, Python and Django, with a strong emphasis on code quality and maintainability

• Integrate with third-party payment services (e.g. banks, card schemes, payment networks) and handle edge cases such as ambiguous or delayed responses, settlement timing, and decline-code variance

• Write robust unit and integration tests for all new features and ensure proper validation for critical payment flows

• Collaborate cross-functionally with product, infra, frontend, mobile, and QA teams to define, design, and ship high-impact features

• Guide and mentor junior and mid-level engineers, providing technical leadership through code reviews, design discussions, and pairing sessions

• Lead by example in enforcing clean architecture, clear documentation, and reliable observability practices

• Identify and resolve performance bottlenecks, improve system resilience, and optimise for correctness and traceability

• Stay up to date with emerging technologies and propose improvements aligned with business goals

• Build software with security and compliance in mind, ensuring proper access control, logging, auditing, and PCI scope discipline

• Deploy applications and support operational readiness of services

What you should have

• Bachelor's degree in Computer Science, Software Engineering, or related field.

• 5+ years of backend engineering, with production-level experience in Go, Python and Django

• Has owned a backend service in production through multiple incident cycles — knows where the failure modes live in the payment domain.

• Demonstrated track record integrating bank, card, or payment-gateway APIs end-to-end (authorisation, capture, 3DS, webhook handling, reconciliation).

• Strong Go, Python and Django proficiency at production scale.

• Comfortable across asynchronous workers and event-driven patterns (Kafka).

• MySQL at scale — replication, read-replica patterns, sharding, schema-migration discipline.

• Redis for cache, session, and queue patterns.

• Hands-on with payment-grade security controls — KMS-backed envelope encryption, signed webhooks, secret management, OWASP-aware coding.

• Cloud infrastructure on GCP (AWS acceptable); IaC familiarity (Terraform).

• CI/CD pipelines with SAST, SCA, and secret-scanning gates.

• Strong technical communication in English; comfortable writing design documents and ADRs.

• Has owned incidents end-to-end including post-mortems and corrective-action follow-through.
