Your role in the team

  • You develop and operate highly scalable Java applications with Apache Kafka for leading financial institutions and other major players in the German financial market.
  • As a Technical Lead, you will be responsible for the design and implementation of event-driven microservices architectures in the depot and securities environment.
  • You modernize legacy systems (HOST/COBOL) by building future-proof cloud-native solutions with Java, Spring Boot, Kafka, and Kubernetes.
  • In close collaboration with business units, Product Owners, and architects, you will shape the digital transformation of critical financial processes – from cash allocation to securities transactions and order processing.
  • You ensure compliance with regulatory requirements (BaFin, MiFID II) as well as the highest security and compliance standards.
  • Together with cross-functional teams, you drive innovative solutions forward: from proof of concept to the productive scaling of millions of transactions daily. You always keep an eye on performance, stability, availability, and data integrity — especially in highly regulated financial services environments.
  • You bring your expertise in code reviews, pair programming, and as a mentor for junior and mid-level developers.

Our expectations of you

Education

  • You have a degree in (Business) Informatics or a qualification in a comparable field of study. However, other specializations can also be interesting and suitable for us!

Qualifications

  • You are passionate about agile worlds, Clean Code, software architecture, and enjoy translating complex technical requirements into elegant technical solutions.
  • Analytical thinking, a high quality awareness, and a strong service orientation are in your blood. Additionally, you enjoy technical leadership without disciplinary responsibility – you lead through competence and conviction.
  • You are ready to travel and flexible to advise our customers on-site nationwide.
  • You speak fluent German and English - great, then you'll feel right at home at Exxeta.

Experience

  • You have several years of Java experience (11+, ideally 17/21) with Spring Boot/Cloud, extensive Kafka expertise (Streams, Connect, Schema Registry, Avro/Protobuf, highly available clusters), solid knowledge of Microservices as well as Event Driven and Domain Driven Design. Additionally, you have experience with REST, GraphQL, and asynchronous communication patterns; ideally, you also bring experience with Docker/Kubernetes and CI/CD pipelines (GitLab, Jenkins, ArgoCD).
  • You already have experience in the Financial Services sector - ideally in custody, securities, or payment transactions. Additionally, you understand technical contexts such as order routing, settlement, corporate actions, cash disposition, or fund accounting, and are familiar with the regulatory requirements of the banking sector (BaFin regulations, compliance, audit trails). Ideally, you have already worked with system platforms such as WP3, OSPlus, or SAP Banking Services, or have modernized legacy systems.
  • You are proficient with tools and technologies such as Maven/Gradle, Git, IntelliJ IDEA, Kafka, PostgreSQL/Oracle, MongoDB, and know how to apply them in daily project work. Experience with Test-Driven Development, JUnit, Testcontainers, and Performance Testing (JMeter, Gatling), as well as knowledge of frontend technologies, is a plus.
  • Experience in the productive use of modern AI tools to support your daily work.

What we offer

  • Normal for us: 30 days of vacation and your sabbatical.
  • On-site, remote, or at clients' locations? Your working style is tailored to client needs and project requirements.
  • With us, you work with modern hardware. Leasing extra hardware? No problem.
