Junior Payroll Specialist H/F

About This Opportunity

We are representing a confidential defense technology organization in their search for a Junior Payroll Specialist to join their team in Paris. Our client is a rapidly scaling company in the aerospace and defense sector, currently expanding their operations across Europe and beyond.

This is a hands-on ownership role where you will manage the complete French payroll function. You'll be the trusted expert ensuring accuracy, compliance, and timely execution of all payroll operations in a fast-paced, high-growth environment. This is not a back-office support position—you will own the monthly payroll cycle end-to-end and serve as the primary point of contact for all payroll-related matters.

Responsibilities

Payroll Operations

• Manage the complete monthly payroll cycle on PayFit: variable element input, payslip validation, anomaly detection, and final approval coordination
• Collect, verify, and integrate monthly variables including absences, RTT, overtime, bonuses, expenses, and equity-related elements
• Ensure accuracy and compliance of all payslips with Syntec collective agreement and French labour law
• Process payroll for all contract types: CDI, CDD, apprenticeship, and VIE (coordinating with Business France)
• Handle employee onboarding and offboarding from a payroll perspective, including final settlement calculations
• Coordinate with external social security bodies: URSSAF, CPAM, prévoyance, mutuelle, and complementary retirement providers

Social Declarations & Compliance

• Prepare and submit monthly and annual social declarations: DSN, URSSAF, and applicable reporting obligations
• Monitor regulatory changes in French payroll law and Syntec collective agreement updates, implementing necessary adjustments
• Track and manage statutory absences including sick leave and maternity/paternity leave in coordination with CPAM
• Ensure compliance with legal minimums: SMIC, mandatory benefits, and Syntec classification benchmarks
• Maintain organized, audit-ready payroll archives and documentation

Employee Administration & HR Operations

• Serve as first point of contact for employee payroll queries, providing accurate and timely responses
• Manage administrative lifecycle documents: employment contracts, amendments, attestations, and work certificates
• Maintain and update employee records in PayFit and internal HR systems
• Support onboarding processes: DPAE, health insurance affiliation, and prévoyance enrollment
• Manage offboarding documentation: final settlements, end-of-contract documents, and unemployment attestations

Finance & Reporting Coordination

• Produce monthly payroll reports and cost breakdowns for the Finance team
• Support preparation of payroll-related provisions and accruals for accounting purposes
• Contribute to annual salary review processes by modeling compensation changes and payroll impacts
• Assist with payroll data preparation for audits, due diligence, and investor reporting

What We're Looking For

Essential Requirements

• 1–3 years of experience in payroll administration, HR operations, or combined payroll/HR-admin roles
• Operational proficiency in PayFit—this is mandatory and you must be able to work in the system from day one
• Startup experience is required: you must be comfortable in fast-moving environments where processes are evolving and autonomy is expected
• Solid understanding of French payroll mechanics and social legislation
• Experience managing a full monthly payroll cycle independently
• Fluency in French is mandatory; English proficiency is a plus

Skills & Qualities

• Rigorous and meticulous—payroll errors affect employees' lives, and you take accuracy seriously
• Organized and reliable—you consistently meet monthly deadlines in dynamic environments
• Proactive—you identify issues, anticipate challenges, and propose improvements without prompting
• Service-minded—you handle employee queries with patience, accuracy, and discretion
• Comfortable with numbers and data—at ease with spreadsheets, reconciliation, and cross-checking
• Discrete and trustworthy—you handle sensitive compensation and personal data daily
• Familiarity with Syntec collective agreement is a strong plus
