PBT Group is seeking a skilled Android Payments Engineer to join a high-performing Payments Technology team. The successful candidate will contribute to the development and maintenance of card machine applications running on Android-based POS devices within a secure, high-throughput financial services environment.

This role requires strong native Android expertise combined with deep payments domain experience, particularly in card-present transactions and payment terminal integrations.

Key Responsibilities

• Design, develop, and maintain Android applications for POS (Point of Sale) devices

• Integrate and support payment terminal hardware components such as card readers, NFC modules, and PIN pads

• Implement and maintain EMV-compliant transaction flows (contact and/or contactless)

• Work with ISO 8583 messaging for financial transaction processing

• Ensure robust, secure, and performant payment application behaviour

• Collaborate with cross-functional teams including backend services, infrastructure, and product stakeholders

• Troubleshoot and resolve issues across embedded hardware/software environments

• Contribute to code reviews, best practices, and continuous improvement initiatives

Minimum Requirements (Must-Have)

• Strong proficiency in native Android development using Java and/or Kotlin

• Proven experience working with EMV protocols (contact and/or contactless payments)

• Solid understanding of ISO 8583 financial messaging standards

• Hands-on experience integrating Android applications with hardware peripherals (e.g. card readers, NFC, PIN pads)

• Experience using AIDL / IPC mechanisms for hardware communication

• Demonstrated experience in payments, fintech, or financial services environments

Preferred / Advantageous Skills

• Exposure to cross-platform frameworks (React Native, Ionic, Capacitor) in addition to native Android

• Understanding of PCI PTS and/or PA-DSS compliance standards

• Experience with cryptographic key management (e.g. DUKPT, MK-SK)

• Prior experience working with payment terminal vendors or fintech organisations (e.g. PAX, Ingenico, Verifone, ECentric, Synthesis)

Important Considerations

• Native Android development is non-negotiable; candidates with primarily cross-platform experience will not be considered

• Candidates must be able to demonstrate hands-on EMV or payment terminal experience

• This is a specialist role within payments infrastructure, not a general mobile development position

Additional Information

• Contract engagement with the possibility of permanent employment based on performance and business requirements

• Competitive market-related rate (to be determined by PBT Group)
