Job Summary
You design and implement complex end-to-end architectures for data processes, lead legacy replacements, conceptualize data science use cases, and enforce clear architecture standards for international teams.
Job Technologies
Your role in the team
- You are responsible for the overall management of a heterogeneous, historically grown software and data landscape with multiple mission-critical systems and sustainably shape the technical target architecture at the domain level.
- You design and oversee end-to-end architectures for highly complex production, fleet, and data processes, including thorough make-or-buy decisions, in-house developed core components, and the integration of specialized third-party providers, all aligned with strictly applied EDA and DDD principles.
- You plan and manage legacy decommissioning in ongoing 24/7 operations using Strangler Fig patterns, event-driven integration, and API-First strategies – including measurable achievement of goals in resilience, observability, security, and regulatory compliance.
- You design and implement complex data science and optimization use cases (e.g., master data harmonization, wagon cycle performance tracking, fleet and circulation optimization, track cancellation forecasts) from domain modeling to stable operation.
- You define and establish binding architecture, data, and event standards, SLOs, Data Contracts, and Contract Tests, and orchestrate cross-domain modernization initiatives with multiple international teams.
- You make and document extensive architecture decisions (ADRs/RFCs), represent them to management, business units, and external partners, and steer their implementation consistently through backlogs, roadmaps, and governance formats.

Our expectations of you
Qualifications
- You have expert-level proficiency in event-driven architectures, Domain-Driven Design (including Strategic & Tactical Design), API design, Cloud-Native deployment patterns, as well as CI/CD, observability, and SRE-related operational models.
- You have demonstrably been responsible for complex legacy transitions (side-by-side operation, zero-downtime migrations, data and event reconciliation) and are familiar with the real organizational and technical pitfalls of such projects.
- You communicate at eye level with the specialist departments, management, and technical experts.
Experience
- You have several years of professional experience in enterprise software or data platform engineering, including multiple years in cross-cutting architecture, principal, or lead roles in highly available, mission-critical environments.
- You bring deep domain-specific expertise in EVU production processes, fleet, asset, and maintenance systems – ideally from several years of project experience in the railway or logistics industry.
- You possess extensive practical experience in data science and optimization techniques (ML, MLOps, mathematical optimization, record linkage, time series analysis) with Python, as well as in the production deployment of MS Fabric in Azure cloud environments.
