Qualifications

• 6+ years of professional software engineering experience delivering production Java applications.
• Strong command of Java 25 features and idioms (records, sealed classes, virtual threads, pattern matching).
• Solid experience with Spring Boot, including dependency injection, REST, data access, and testing.
• Proven solutioning skills: design simpler, maintainable solutions for complex business needs."
• Proficiency in writing clean, maintainable, and well-tested code, applying best practices in software design and deployment.
• Hands‑on experience with event-driven architectures and messaging systems such as Azure Service Bus, Azure Event Hubs, RabbitMQ, Kafka, or equivalent.
• Practical experience with cloud platforms (Microsoft Azure preferred; AWS or GCP also valued).
• Experience with relational databases (PostgreSQL or equivalent), including schema design, query optimisation, and migration tools (Flyway or Liquibase).
• Experience implementing test strategies (unit, integration, and regression), including defining the approach rather than just writing tests.
• Demonstrated ability to own and lead the technical delivery of a project or service, including architectural decisions, stakeholder coordination, and cross‑team collaboration.
• Experience working with Agile methodologies (Scrum or Kanban).
• Strong written and verbal English communication skills.
• Proactive, ownership‑driven mindset with a focus on quality, reliability, and security.

Responsabilités

• Lead design and architecture of platform capabilities and customer‑facing integrations, contributing meaningfully to overall system architecture decisions.
• Collaborate with product managers and engineers across teams to define robust, scalable solutions that balance delivery speed with long‑term maintainability.
• Drive architectural decisions for event‑driven microservices, documenting choices as architecture decision records (ADRs), ensuring alignment on trade‑offs, and sharing context widely.
• Design, build, and maintain high‑performance, reusable, and reliable microservices that integrate the client’s customer data with external marketing platforms.
• Develop and maintain event‑driven solutions on Azure Service Bus and Azure Event Hubs, processing high‑volume customer data streams reliably and at scale.
• Build and evolve gateway services, applying patterns such as gateway, outbox, and idempotent processing.
• Contribute to shared libraries and internal developer tooling that raise the quality bar across the team.
• Implement new features in production with full accountability for code quality, best practices, and operational readiness.
• Define and implement test strategies (unit, integration, functional, and regression) to ensure consistent platform performance and confidence in every release.
• Champion CI/CD best practices using Azure DevOps pipelines, ensuring fast, reliable, and fully automated software delivery.
• Maintain high‑quality documentation, including runbooks, API specs, system design documents, and operational guides.
• Mentor and support fellow engineers, conduct thorough code reviews, and actively shape the team’s engineering culture and standards.
• Manage infrastructure as code using Terraform and Helm, deploying services to Kubernetes on Microsoft Azure.
• Collaborate with cloud platform and security teams to design secure, resilient services across private and public cloud environments.
• Write secure code: apply a layered defence model, follow DevSecOps practices, and treat security as a first‑class concern alongside reliability and performance.
• Ensure observability by instrumenting services with New Relic APM, defining meaningful alerts, and owning the operational health of your systems.
• Discover, evaluate, and advocate for new technologies, proactively identifying tools, libraries, and patterns that can meaningfully improve team productivity or system quality.
• Leverage AI coding tools (e.g., Tabnine) to drive engineering efficiency, and help the team adopt these practices effectively.
• Automate workflows and build tooling to eliminate toil and enhance the developer experience.
