Job description

Role overview

The role is within the Terminal Development team, reporting to the team manager. This position has a focus on the development of the payment application that runs on our payment terminals. This is a technical role where the successful candidate will gain an understanding of our payment business on all the industries that Planet works with. All the developments will be running in payment terminals that run Linux or Android OS. These devices are compliant with all the latest PCI security rules, and they also include a secure processor to run all the payment sensitive data.

Currently we work with four different payment terminal manufacturers, PAX, Ingenico, Verifone and Worldline. Our main programming language is Java, but we also work with C++, and with Android and iOS environments.

Payment terminals need to be robust and easy to use, meaning that the software needs to run without any failure and very smoothly for the end‑user.

The role will involve liaising with our architecture and Solution Engineering teams, understanding, and documenting the requirements. You will be required to work on multiple projects simultaneously, liaising directly with the Project Manager for that project.

What you will do

• Develop state-of-the-art payment applications for the Planet group.
• Advise on technical aspects and working with a variety of systems.
• Attend meetings and calls with both internal and external parties and provide technical advice to all.
• Have the ability to read and understand technical specifications, including architecture diagrams, payment flows and protocols.
• Participate in the creation of the solution architectures.
• Work with third‑party software integrators, suppliers and developers.
• Provide architecture and integration technical documentation of the developed solutions.
• Work collaboratively with the rest of the Development team and assist colleagues as required and help alleviate acute resource constraints or project sprint cycles.

The role requires a wide scope of technical knowledge and the ability to apply this knowledge in different circumstances when solutions are needed fast.

Who you are

• Technical/scientific university degree or equivalent.
• A minimum of 2 years of experience in Java development.
• A minimum of 1 year of experience in Android development.
• Understand the limitations of low‑powered mobile devices, and what needs to be done to make a good user experience while using them.
• Real‑time application development.
• Multithreading.
• Experience using GIT.
• REST Web Services.
• Understanding of security and encryption standards.
• Network and communication: TCP/IP, SSL, TLS, HTTP, HTTPS, Serial.
• UML (state charts, use cases, activity and sequence diagrams).
• Software development lifecycle and Software testing lifecycle.
• Linux operating systems.
• Excellent analytical and proactive ability to work unsupervised and under pressure.
• Strong relationship management with the partners throughout several countries.
• Good communication and user document writing skills (English mandatory).
• Skilled multitasker able to prioritize multiple tasks, maintaining overview and focus.
• Team player, eager to assist colleagues.

Nice to have

• C or C++ proven knowledge is an advantage, but not essential.
• Android native development using Java programming language.
