About the role

Tailored client support: You don’t work "for" clients, you work "with" them.
Modern, optimized accounting: No more tedious manual data entry. Thanks to our AI tools (Yooz, Pennylane), you can focus on what matters.
A key role on the team: You will be responsible for maintaining clients' accounts (verifying accounting entries, and preparing VAT, corporate tax (IS) and personal income tax (IR) filings).
Opportunity to take initiative: Here, even an accounting assistant can challenge a process, suggest improvements and see their ideas implemented.
Rapid skills development: You will be trained in account review and tax return packages (liasses fiscales).

You hold a Bac+2/3 (equivalent to 2–3 years of higher education).
You have at least 2 years' experience in an accounting firm (including apprenticeships and internships).
You are proficient in bookkeeping, common tax filings (VAT, corporate tax, personal income tax) and comfortable with digital tools.
Account review does not intimidate you; if you are not yet fully proficient, you are ready to develop this skill.
Curious, proactive and detail-oriented, you enjoy working in a team and supporting clients with a pedagogical approach.
You are eager to learn, progress and share your knowledge, including by training an apprentice.

Benefits

Work-life balance: flexible hours and an organization designed to avoid prolonged high-intensity periods.
Fast career progression: personalized development path, mentoring and regular training.
A stepping stone to expertise: possibility to complete your DEC internship (Diplôme d'Expertise Comptable) within the firm.
Human-scale firm with the backing of a national network: the proximity and friendliness of a small office combined with the resources and best practices of a nationwide network.
Stimulating environment: a close-knit team in a human-sized firm with annual events.
Competitive package: fixed salary + meal vouchers + health insurance covered at 99%.
Varied, rewarding assignments: not assembly-line work but genuine skills development.
Exclusive benefits and boosted purchasing power: access to an outsourced employee benefits service (CSE) with discounts on travel, restaurants, cultural activities and shopping.
