Position

We are currently looking for a candidate for the position of Technical Transformation Lead (he/she) for our client from the Government Financial Services industry.

Additional information

The project is a major, long-term digital transformation initiative within the European Public Finance sector. The primary objective is to fully modernize a critical, national-scale fiscal legacy platform, shifting from a monolithic architecture into a highly secure, cloud-native ecosystem. This is a high-stakes initiative to future-proof core financial systems, improve operational efficiency, and protect highly sensitive financial data at the federal level.

Location: Remote from Poland with a hybrid component.

The Challenge: While the project deals with migrating complex legacy structures, you will have a “Greenfield” mandate to build technical teams from scratch and shape the modern architectural roadmap (Microservices, API-first, Event-driven).

Offered salary

Salary: from 1500 to 2500 PLN net/day, depending on experience and competences.

You’re ideal for this role if you:

  • You live and breathe Java (Spring Boot), Angular, Kubernetes, and containerization. You have successfully designed and implemented production-grade API-first layouts and Event-driven architectures.
  • You have deep architectural knowledge and hands-on roots in Java, Spring Boot, Angular, and REST APIs. You are comfortable dealing with both modern platforms and complex legacy environments (WebLogic, DB2, Monoliths/Mainframes).
  • You have practical experience with Kubernetes, containerization, and Event-driven architecture. You champion a strong DevOps culture with automated CI/CD pipelines, Git, and modern observability (ELK stack).
  • You come from a large, recognizable enterprise (ideally Banking or Insurance). You understand how to manage and secure highly sensitive financial data under strict compliance frameworks such as DORA, NIS 2.0, and ISO 27001.
  • You possess the leadership skills required to build, scale, and mentor multidisciplinary Agile squads (Scrum/SAFe) from scratch, driving technical change management and reducing technical debt.
  • Your English is at a very high professional level. You are excellent at facilitating Agile workshops, collaborating with Enterprise Architects, and managing relationships with demanding corporate/public stakeholders.

Nice to have:

  • Prior experience working on large-scale digital transformation programs for government bodies, federal agencies, or international public institutions.
  • While English is the primary and mandatory working language for this role, any professional proficiency in French or Dutch is a valuable asset given the project’s geographical context.
  • Professional certifications related to cloud architecture (e.g., AWS, Azure, GCP), Kubernetes (CKA/CKAD), or IT security compliance.
  • Formal certifications in scaled Agile frameworks, such as SAFe (e.g., SAFe Agilist, SAFe Architect) or advanced Scrum roles.

Your day-to-day responsibilities include:​

  • Analyzing and structuring complex business requirements, translating them into secure, scalable, microservices-based solutions.
  • Contributing directly to the product and technical roadmap definition while actively supporting the migration from legacy systems.
  • Partnering with Enterprise Architects to design and secure modern API-first and event-driven pattern
  • Facilitating Agile workshops, ceremonies, and collaborative sessions to maintain an incremental delivery model.
  • Coordinating alignment between diverse business and IT stakeholders, while supporting technical change management across teams.
  • Contributing to the continuous improvement of DevOps practices, automation, and delivery speed.
  • You will operate within a robust, critical enterprise environment combining stable historical systems with a rapidly growing cloud-native ecosystem:
  • Backend & Frontend: Java, Spring Boot, Angular
  • Architecture: Microservices, REST APIs, Event-driven architecture
  • Infrastructure & Platforms: Kubernetes, WebLogic, DB2
  • DevOps & Observability: CI/CD pipelines, Git, ELK stack
  • OS & Tools: Linux, Windows, IntelliJ, Atlassian Suite
  • Methodology: Scrum / Hybrid Agile (SAFe)
