Paymentology is the first truly global issuer-processor, giving banks and fintechs the technology, team, and experience to rapidly issue and process Mastercard, Visa, and UnionPay cards across more than 50 countries, at scale.

Our advanced, multi-cloud platform, offering both shared and dedicated processing instances, vast global presence, and richer, real-time data, set us apart as the leader in payments.

We are seeking a highly skilled and motivated **Senior Software Engineer** to join our team and contribute to our initiative of improving our existing platform. We seek a developer who values the importance of code readability, modularity, and maintainability. The ideal candidate will have good experience in Java development and a strong understanding of software development best practices. As a member of our team, you will be responsible for writing high-quality, maintainable, and scalable code that is easy to read, test, and modify.

## Tasks

*   Write clean, self-explanatory, and well-documented code that is easy to read and understand.
*   Design and implement small, modular functions with clear and descriptive names.
*   Ensure code consistency by following established coding styles, naming conventions, and formatting guidelines.
*   Maintain a modular and highly cohesive codebase by dividing the code into domains, business logic, ports, and modules.
*   Design code around interfaces, not implementations, to enhance code reuse and maintainability.
*   Write code that is easy to test and reproduce with tests first.
*   Ensure that code is secure and complies with industry-standard security protocols.
*   Optimize code efficiency and scalability by using best practices and modern technologies.
*   Collaborate with other developers and stakeholders to identify and implement new  
    features that improve the platform's usability, maintainability, and scalability.
*   Optimize code efficiency, observability, and scalability by using best practices and modern technologies, such as gRPC, Kafka, Docker containers, OpenTelemetry, and Prometheus.

## Requirements

*   Good understanding of software development methodologies, design patterns, and best practices.
*   Experience in writing clean, maintainable, and scalable code using Java and related technologies.
*   Experience in designing and implementing small, modular functions with clear and descriptive names.
*   Understanding of database design and development using Hibernate ORM and Liquibase (PostgreSQL knowledge is a plus).
*   Experience in designing code around interfaces to enhance code reuse and maintainability.
*   Good to have experience in writing secure code that complies with industry standards (like OWASP, NIST, PCI-DSS, ISO 27001).
*   Strong analytical and problem-solving skills.
*   Ability to work independently and as part of a team.
*   Ability to communicate your work and progress to the team.
