We are a product company – we build and continuously develop our own Master Data
Management platform. This gives us a stable working environment and provides our people
with a genuine opportunity to influence the shape and direction of the solutions we build.
Instead of working on short-term projects for different clients, you will have the opportunity to
contribute to a product over the long term and see the impact of your work.
We are looking for an experienced Team Lead (Java) who combines strong people leadership
skills with deep technical expertise. As a Team Lead, you will support and develop your team
members while taking responsibility for the technical quality of the systems your team builds
and operates.
This is a broad and comprehensive role, made possible by the way our teams are structured: our
Team Leads work with small, 3–5-person teams and have a very limited number of meetings.
Apart from the daily, you mainly participate in meetings directly related to your team’s work
and needs – typically around 2–3 hours per week in total. This allows you to spend most of your
time working with your team, making technical decisions and supporting people’s development.
We expect you to have a very good understanding of your team’s technology stack, the ability to
organise and coordinate the team’s work, and confidence in making technical decisions. Your
impact will extend beyond your own team, including collaboration with other teams to ensure
that everyone remains focused on delivering value. The ideal candidate has a strong background in backend development using modern Java
technologies, several years of professional experience, and experience mentoring, leading or
coordinating engineers. We are looking for a team-oriented person who values collaboration,
knowledge sharing and collective problem-solving. A genuine interest in data and databases will
be a strong advantage.

providing data quality insights. The product is powered by a rules engine built on a
knowledge graph (RDF/SPARQL) and curated global reference data.
• Duplicate Guard – detection, analysis and consolidation of duplicate business partner
records within and across datasets. It includes a matching engine with data cleansing
mechanisms and phonetic, geospatial and exact comparators, continuous duplicate
monitoring, and consolidation rules leading to the creation of so-called golden records.
• Tax Guard – verification and validation of direct and indirect tax identifiers (including EU
VAT), as well as verification of names and addresses against official registers, both in
transactional and monitoring modes through a headless API Key Responsibilities – People Leadership

knowledge graph design. These technologies are used in the Data Quality Guard rules
engine, where records are translated into RDF triples and validated using SPARQL-based
rules against curated global reference data.
