Architect IT

At Pretius, we are looking for an IT Architect to lead an incremental system transformation toward a more modular, microservice-oriented architecture. We are working with a system that has evolved over many years and has become increasingly difficult to change and scale. It currently consists of a monolith supported by several services, shared database schemas, and tightly coupled processes. The architectural transformation is already aligned and supported at the leadership level and is being driven top-down across the project. This role is expected to shape and execute that direction in close collaboration with engineering teams, turning strategy into concrete, working solutions. This is not a slide-driven or purely advisory role. It is a role for someone who enjoys practical, deep technical work: diagnosing problems, defining guardrails, reshaping boundaries, stabilizing long-running processes, and improving integrations step by step. Project / Role • Analyze existing business flows (users, orders, devices, vouchers) and identify meaningful domain boundaries • Design and implement an event-driven approach, including outbox patterns, idempotency, and sagas/compensation mechanisms • Move external integrations into a dedicated integration / anti-corruption layer (inbound and outbound) • Gradually decouple the system from a shared database model (data ownership → separation) • Improve observability across the system (tracing, correlation, metrics, structured logging) • Work closely with engineering teams through code reviews, pairing, and architectural decision records (ADRs) Requirements • 8+ years of experience in IT, including at least 3 years in an architect role • Proven experience modernizing legacy or monolithic systems in production environments • Practical knowledge of designing long-running, distributed processes (sagas, compensations) • Knowledge of architecture management tools and methods (TOGAF, ArchiMate, C4, UML) • Hands-on experience with event-driven architectures (Kafka, RabbitMQ, or similar) • Ability to design solutions in cloud environments (AWS experience is a plus) • A pragmatic, delivery-focused mindset: stabilization first, incremental improvements, realistic plans • Experience in database design and modeling, as well as using tools such as Enterprise Architect and Flowchart Maker & Online Diagram Software • Experience in developing systems built with Java technology • Willingness to commit long-term and take ownership Nice to Have • Practical experience with DDD and Bounded Contexts (beyond theory) • Experience with BPMN or workflow engines (Camunda, Zeebe, Temporal, etc.) • Background in database separation and data migration strategies The culture is straightforward and non-corporate. There’s space for a normal atmosphere and a sense of humor, and when it’s time to work, people focus and deliver. No theatre, no buzzwords — just people who care about doing solid engineering. What do we offer at Pretius? • We focus on long- term relationships based on fair principles and reliability • Co-financing of the Multisport card and Medicover private healthcare • Modern office available • Team bonding activities, internal courses, conferences, certifications
