Job Description:

You will lead the data migration workstream for a compliance-critical public-sector registry system. The core challenge: converting a fully normalised relational database into an event-sourced architecture, migrating large volumes of document files, and ensuring every data related decision is documented and approved by the client. This is not a standard backend role. You need to understand legacy data deeply, make domain-informed decisions under uncertainty, and deliver under tight timelines with high client visibility.

Job Responsibility:

  • Lead the data migration workstream for a compliance-critical public-sector registry system
  • Converting a fully normalised relational database into an event-sourced architecture, migrating large volumes of document files, and ensuring every data related decision is documented and approved by the client

Requirements:

  • Proven experience with large-scale data migration projects: ETL, transformation pipelines, cutover planning
  • Hands-on experience with event sourcing (relational-to-event model transformation): decomposing relational data into domain events with deterministic ordering
  • Experience with legacy database analysis: reverse-engineering un(der)documented schemas, understanding data semantics and relationships without complete documentation
  • Experience with data quality handling: nulls, duplicates, inconsistent formats, missing fields, validation rules
  • Familiarity with document/file migration at scale: metadata extraction, filename parsing, large-volume validation and dealing with corrupted or ambiguous data or metadata
  • Strong knowledge of backend design patterns (dependency injection, repository, mediator, factory)
  • English language skills (B2+ minimum): required for clear communication with stakeholders and documentation of architectural decisions
  • Hands-on experience with CQRS, Domain-Driven Design, and Event Sourcing
  • Ability to design and implement aggregates, entities, value objects, and bounded contexts
  • Skilled in building systems that enforce clear separation of concerns, scalability, and maintainability
  • Solid understanding of clean architecture principles
  • Strong experience with .NET / C# backend development
  • Practical knowledge of Modular Monolith
  • Experience with PostgreSQL and modern ORM frameworks (e.g. Entity Framework or equivalent)
  • Experience with Marten DB or willingness to learn quickly
  • Exposure to CosmosDB or similar NoSQL/document databases
  • Experience designing and consuming RESTful APIs
  • Docker: confident setup, troubleshooting, and local environment management
  • Good exposure to cloud environments, ideally Azure infrastructure and services
  • Comfortable working with SQL at an advanced level: complex queries, schema analysis, data profiling, and ad-hoc investigation of production data
  • Rapid domain understanding: ability to quickly absorb unfamiliar, regulated business domains (registries, compliance, legal records)
  • Governance mindset: documenting decisions, maintaining audit trails, getting formal client sign-off
  • Experience working with subject matter experts to define and validate data transformations and mappings
  • Public-sector, institutional or regulatory software experience is a significant advantage
What we offer:
  • 100% remote work
  • Flexible hours
  • International projects
  • Business english lessons
  • Participation in charity actions
  • In-house technology workshops
