Key Responsibilities — Dein Aufgabenbereich
Employee & Management Support — First Point of Contact for All HR Matters
- Serve as the first point of contact (erste Ansprechperson) for employees across all HR-related enquiries — handling questions on employment contracts, working time, payroll components, entitlements, benefits, and general workplace matters with the combination of HR technical accuracy, service orientation, and diplomatic communication that makes employees feel genuinely supported rather than deflected, resolving queries independently where within scope and escalating or forwarding to the correct internal specialist where expertise or authority requires it
- Support the management team (Geschäftsführung) on all personnel-relevant questions — providing the HR advisory support that allows the management team to make well-informed, legally compliant, and operationally practical decisions on personnel matters including hiring, changes to employment terms, performance management, disciplinary procedures, and employee departure processes
- Manage all personnel processes from hire to exit — owning the complete administrative and advisory lifecycle of each employee’s time with the organization, from the initial employment contract through to the final reference letter and social insurance deregistration, ensuring that every step is handled correctly, on time, and with the confidentiality and professionalism that German employment law and organizational trust require
- Prepare employment contracts, certificates, reference letters, and other personnel documents — producing the legally accurate, correctly formatted, and clearly written employment documents that form the contractual and administrative foundation of each employee’s relationship with Treuhand, applying knowledge of current German employment law requirements and organizational standards to every document produced
Payroll Processing — Gehaltsabrechnung & Entgeltabrechnung
- Independently run monthly payroll (Gehaltsabrechnung) for a defined employee group — applying comprehensive understanding of German payroll mechanics including gross-to-net calculation, Lohnsteuer determination, Sozialversicherungsbeiträge (Kranken-, Pflege-, Renten-, Arbeitslosenversicherung) calculation, wage continuation (Entgeltfortzahlung) in cases of illness and public holidays, and the specific payroll processing workflow in DATEV LODAS to produce accurate, on-time monthly payslips and payroll reports for the assigned employee group
- Apply knowledge of Entgeltfortzahlung and Entgeltumwandlung — managing the specific payroll complications that arise during periods of employee illness (Entgeltfortzahlung im Krankheitsfall), public holidays, parental leave, and other statutory absence entitlements, as well as the deferred salary conversion arrangements (Entgeltumwandlung) for company pension and other benefit schemes that require specific payroll treatment
- Maintain current knowledge of Lohnsteuerrecht, Sozialversicherungsrecht, and Arbeitsrecht — keeping payroll and HR advisory practice aligned with the regular legislative and regulatory updates that German employment tax, social insurance, and labor law produce throughout the year, preventing compliance gaps that create financial or legal risk for the organization
- Provide initial advisory support on payroll, contract, and working time questions — giving employees and managers the accurate, accessible, and clearly communicated first-level answers to payroll and employment conditions questions that reduce unnecessary escalations to senior HR specialists and improve the speed and quality of the HR service experience for Treuhand’s workforce
HR Administration, Data Management & System Maintenance
- Ensure correct recording, maintenance, and updating of HR master data (Personalstammdaten) in HR systems — maintaining the data accuracy and completeness standards in DATEV and other HR management systems that ensure payroll processing, reporting, and regulatory compliance outputs are based on correct, current information rather than outdated or incomplete records that produce processing errors and regulatory non-compliance
- Handle reporting and certification processes (Berichts- und Bescheinigungswesen) — producing the Arbeitsbescheinigungen for Agentur für Arbeit, Verdienstbescheinigungen for external purposes, Elterngeld-Bescheinigungen, and other statutory and organizational certificates and reports with the accuracy, format compliance, and timeliness that statutory deadlines and employee needs require
- Maintain and update personnel files (Personalakten) — ensuring that both digital and physical personnel files are maintained in the organized, complete, and access-controlled manner that data protection requirements (DSGVO), internal governance standards, and audit readiness demand throughout each employee’s employment lifecycle
- Participate in HR projects and process optimization — contributing the practical HR administration perspective and daily operational knowledge that helps HR project teams design and implement process improvements that are not only theoretically sound but practically workable within the specific operational context of Treuhand’s HR team
Qualifications & Requirements
Required Profile
- Completed commercial apprenticeship (abgeschlossene kaufmännische Ausbildung) — in a business administration, office management, payroll specialist, or HR specialist qualification that provides the formal foundation for payroll processing and HR administration at professional standard
- Ideally several years of professional experience in HR (Personalwesen) or in payroll processing (Lohn- und Gehaltsabrechnung) — with a track record that demonstrates reliable independent payroll production and competent employee advisory support
- Comprehensive understanding of payroll (Gehaltsabrechnung) and associated German tax and social insurance law topics — sufficient to process payroll accurately and to advise employees and managers on first-level payroll questions
- High service orientation, communication ability, and professional discretion with confidential personnel matters — the core personal competencies that make an HR professional genuinely valued by the employees and managers they serve
- Independent, structured, reliable, deadline-conscious working style with hands-on mentality — the operational discipline that ensures HR administration tasks are completed accurately and on time without supervision
Strongly Preferred
- Experience with DATEV / LODAS — for immediate productive contribution to the team’s monthly payroll processing from the first weeks in the role
- Knowledge of Entgeltfortzahlung, Entgeltumwandlung, and related payroll-adjacent topics — for confident handling of the specific payroll complexity that illness absence, benefit arrangements, and statutory entitlements introduce
