About this role

Developer – AI-Enabled Delivery Mindbox Sp. z o.o. Daily tasks: - Design, build, test, and release Java microservices and related components in an enterprise environment. - Contribute to solution design and integration patterns, ensuring alignment with architecture and non-functional requirements. - Identify and mitigate technical risks and dependencies impacting delivery. - Apply and enhance engineering standards, including coding practices, branching, TDD, CI/CD pipelines, and automated quality gates.

- Deliver comprehensive unit, integration, and contract tests (JUnit, Mockito, API testing). - Participate in peer reviews for design, code, and security, remediating issues promptly. - Use AI-assisted tooling (e.g., GitHub Copilot) to accelerate delivery responsibly, meeting security and traceability standards. - Apply guardrails for AI-generated code, including review, audit, and IP compliance. - Contribute to safe GenAI integration patterns, such as LLM usage, retrieval-augmented generation (RAG), and agent workflows with human review.

- Embed security-by-design, including vulnerability management and secure coding practices. - Ensure production readiness: observability, logging, monitoring, performance testing, and incident support. - Work with cross-functional teams to deliver integrated outcomes and improve developer velocity. - Promote an inclusive, collaborative culture based on engineering excellence and innovation. Musts: Java, Microservices, Spring Boot, RDBMS, Oracle, Unit testing, Testing, JUnit, Mockito, CD pipelines, GitLab, SAST, DAST, REST API, Cloud platform 4 - 8 years of experience.

Strong hands-on experience with Java microservices development (Spring Boot). Solid understanding of RDBMS (Oracle/PostgreSQL): schema design, performance tuning, and transaction handling. In-depth knowledge of unit testing, integration testing, contract testing (JUnit, Mockito, Testcontainers). Proven experience with CI/CD pipelines (Jenkins/GitLab) and quality gates (Sonar, SAST/DAST scanning). Familiarity with integration patterns (REST APIs, event-driven messaging).

Experience in technical design , with pragmatic trade-offs under delivery constraints. Hands-on experience with cloud platforms (GCP) . Practical exposure to GenAI concepts and tools (LLMs, RAG, agentic workflows) and associated governance. Nice to have: Previous work in regulated industries with strong audit and operational control. Knowledge of cloud-native patterns : containers, Kubernetes, service mesh, observability tooling.

Exposure to performance engineering and resilience testing . Prior participation in AI-enabled SDLC adoption with governance frameworks. Hands-on with GenAI prototyping (prompt engineering, RAG pipelines, evaluation methods). Joining this project you’ll become part of Mindbox – a tech-driven company where consulting, engineering, and talent meet to build meaningful digital solutions. We’ll back you up every step of the way, accelerate your development, and ensure your skills make a difference.

At Mindbox we connect top IT talents with technology projects for leading enterprises across Europe. oin our team building Global Collateral and Facility Management capabilities for a mission-critical platform replacement program. The goal is to deliver a modern in-house solution leveraging Java microservices, cloud technologies, and AI-assisted engineering practices , with strong governance and quality controls. This is a hands-on engineering role focused on building, integrating, and deploying secure, production-grade services at pace.

You will work across multiple delivery streams in collaboration with Tech Leads, architects, platform, QA, and operations teams, applying modern AI-enabled SDLC techniques while adhering to enterprise security and compliance standards.
