Software Development Engineer - AI Focus

About the role

Onbe is a fast‑growing FinTech that acts as a comprehensive payments partner for its clients. The company transforms payments into an opportunity for innovation, insight, and global connection. The role focuses on AI‑assisted software development, embedding AI coding agents throughout the engineering lifecycle—from analyzing legacy systems to delivering production‑grade microservices.

Responsibilities

• Design, develop, and operate production‑grade Java microservices using Java 21+ and Spring Boot 3.
• Partner with internal SMEs and an external vendor to decompose legacy Java and SQL monolith capabilities into independently deployable, domain‑oriented services.
• Serve as a long‑term owner of the resulting domain service(s) after the vendor engagement, driving architecture, reliability, and evolution.
• Bring a fresh, modern engineering perspective to legacy code and processes, challenging established patterns where better approaches exist.
• Develop and maintain secure RESTful APIs using Spring Boot and API‑first design practices.
• Implement event‑driven integrations using Azure Service Bus or comparable messaging platforms.
• Design and maintain data access layers using JPA/Hibernate, JDBC, and relational databases such as Azure SQL or Microsoft SQL Server.
• Build automated unit, integration, API contract, regression, and end‑to‑end tests, following TDD and shift‑left quality practices.
• Use AI coding agents and other AI‑assisted engineering tools to generate, refactor, test, document, and troubleshoot software while reviewing and owning the final output.
• Containerize and deploy services using Docker, Kubernetes, Azure Kubernetes Service, or Azure Container Apps.
• Contribute to CI/CD pipelines, infrastructure automation, service configuration, secrets management, observability, and production support.
• Monitor application performance, availability, and reliability; participate in incident response and continuous improvement.
• Collaborate with product, architecture, platform, security, QA, and business‑domain teams to deliver complete solutions.

Qualifications

• Bachelor’s degree in Computer Science, Information Technology, or a related field, or equivalent professional experience.
• 5+ years of professional software engineering experience, including substantial hands‑on Java development.
• Strong experience with Java 21+ and modern Java development practices.
• Strong hands‑on experience using AI‑assisted software engineering tools or coding agents, specifically Claude Code.
• Strong hands‑on experience with Spring, Spring Boot, JPA/Hibernate, and REST API development.
• Experience modernizing or migrating monolithic applications to microservices or cloud‑native architectures.
• Experience with relational databases, SQL, data modeling, transactions, and performance tuning.
• Experience with automated testing frameworks such as JUnit, Mockito, and comparable integration or contract‑testing tools.
• Experience with Docker and Kubernetes; Azure Kubernetes Service experience preferred.
• Hands‑on experience with cloud platforms, preferably Azure.
• Experience with CI/CD, Git, Maven or Gradle, and deployment automation.
• Ability to evaluate AI‑generated code for correctness, security, maintainability, performance, and test coverage.
• Strong communication, collaboration, problem‑solving, and end‑to‑end ownership skills.

Preferred Qualifications

• Experience with Agile development methodologies.
• Experience in payments, fintech, banking, insurance, or another regulated industry.
• Familiarity with payment processing, ledgers, settlement, ACH, cards, KYC, fraud controls, PCI, auditability, and sensitive‑data protection.
