You will design, build, and operate event-driven microservices and data pipelines on Azure that connect millions of customers with personalised marketing experiences across channels, while leading architectural decisions, mentoring fellow engineers, and shaping the team’s engineering standards. The team follows a DevOps philosophy, with full ownership from commit to production, on-call support, and continuous delivery, and engineers rotate to the Platform team to deepen their infrastructure expertise.\nHybrid mode with 3 days per week working from the office in Kraków.\nTech stack:\nLanguage: Java 25.\nFramework: Spring Boot 4.\nBuild: Gradle.\nMessaging and streaming: Azure Service Bus,

and idioms (records, sealed classes, virtual threads, pattern matching).\nSolid experience with Spring Boot, including dependency injection, REST, data access, and testing.\nProven solutioning skills: the ability to design simpler, maintainable solutions for complex business needs, not just technically correct ones.\nProficiency in writing clean, maintainable, and well-tested code, applying best practices in software design and deployment.\nHands-on experience with event-driven architectures and messaging systems such as Azure Service Bus, Azure Event Hubs, RabbitMQ, Kafka, or equivalent.\nPractical experience with cloud platforms (Microsoft Azure preferred; AWS or GCP also valued).\nExperience with relational databases (PostgreSQL or equivalent), including schema design, query optimisation, and migration tools (Flyway or Liquibase).\nExperience implementing test strategies (unit, integration, and regression), including defining the approach rather than just writing tests.\nDemonstrated ability to own and lead the technical delivery of a project or service, including architectural decisions, stakeholder coordination, and cross-team collaboration.\nExperience working with Agile methodologies (Scrum or Kanban).\nStrong written and verbal English communication skills.\nProactive, ownership-driven mindset with a focus on quality, reliability, and security.\nWill be a plus\nExperience with Bash and Python 3\nResponsibilities\n Technical leadership and design\nLead the design and architecture of platform capabilities and customer-facing integrations, contributing meaningfully to overall system architecture decisions.\nCollaborate with product managers and engineers across teams to define robust, scalable solutions that balance delivery speed with long-term maintainability.\nDrive architectural decisions for event-driven microservices, documenting choices as architecture decision records (ADRs), ensuring alignment on trade-offs, and sharing context widely.\nCode and development\nDesign, build, and maintain high-performance, reusable, and reliable microservices that integrate the client’s customer data with external marketing platforms.\nDevelop and maintain event-driven solutions on Azure Service Bus and Azure Event Hubs, processing high-volume customer data streams reliably and at scale.\nBuild and evolve gateway services, applying patterns such as gateway, outbox, and idempotent processing.\nContribute to shared libraries and internal developer tooling that raise the quality bar across the team.\nImplement new features in production with full accountability for code quality, best practices, and operational readiness.\nEngineering practices\nDefine and implement test strategies (unit, integration, functional, and regression) to ensure consistent platform performance and confidence in every release.\nChampion CI/CD best practices using Azure DevOps pipelines, ensuring fast, reliable, and fully automated software delivery.\nMaintain high-quality documentation, including runbooks, API specs, system design documents, and operational guides.\nMentor and support fellow engineers, conduct thorough code reviews, and actively shape the team’s engineering culture and standards.\nInfrastructure and security\nManage infrastructure as code using Terraform and Helm, deploying services to Kubernetes on Microsoft Azure.\nCollaborate with cloud platform and security teams to design secure, resilient services across private and public cloud environments.\nWrite secure code: apply a layered defence model, follow DevSecOps practices, and treat security as a first-class concern alongside reliability and performance.\nEnsure observability by instrumenting services with New Relic APM, defining meaningful alerts, and owning the operational health of your systems.\nTechnology advocacy\nDiscover, evaluate, and advocate for new technologies, proactively identifying tools, libraries, and patterns that can meaningfully improve team productivity or system quality.\nLeverage AI coding tools (e.g., Tabnine) to drive engineering efficiency, and help the team adopt these practices effectively.\nAutomate workflows and build tooling to eliminate toil and enhance the developer experience.","description_format":"text","description_chars":6418,"description_truncated":false,"requirements":{"experience_years_min":6,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[{"language":"English","level":"Upper-Intermediate
