ABOUT YOUSIGN

Yousign (soon to be Youtrust) is a European Digital Trust provider, fully compliant with eIDAS and the highest European standards. Our three modules – electronic signatures, identity and document verification, and e-seals – can be used independently or combined within sector-specific workflows, ensuring simple, secure and legally compliant processes for SMEs and mid-sized companies. Hosted and processed entirely in Europe, we guarantee sovereignty, transparency and reliability. As a certified B-Corp, we combine innovation with responsibility – building trust at the heart of every digital exchange. We are entering a key moment as we expand from eSignature to the full Digital Trust chain.

POSITION OVERVIEW

Yousign is building the future of trust and electronic signatures in Europe. As we scale, the regulatory and security landscape is evolving rapidly: eIDAS v2, NIS2, post-quantum cryptography, and increasingly complex technical standards are reshaping the industry. To meet these challenges, we are looking for a Senior Security Engineer to join our Security & Compliance team. This role requires genuine seniority: you will be expected to operate with a high degree of autonomy, make sound judgment calls under ambiguity, and lead initiatives end-to-end without waiting to be directed. You will be a senior voice in the team: mentoring peers, challenging assumptions, and bringing the experience needed to navigate complex trade-offs between compliance, security, and business velocity, while remaining hands-on and deeply embedded in the work.

About the job

Yousign is a European leader in electronic signature solutions, trusted by thousands of businesses to secure and streamline their document signing processes. We operate in a highly regulated environment where compliance isn't optional: it's a competitive differentiator and a foundation of customer trust. Our Security & Compliance team sits at the intersection of regulation, engineering, and operations. We don't just interpret standards: we implement them, audit them, and build the infrastructure that makes Yousign a trusted qualified trust service provider. This role is for someone who thrives in a fast-moving scale-up environment: comfortable with ambiguity, obsessed with pragmatic solutions, and energized by the challenge of scaling compliance operations without sacrificing agility. You'll work with a team that uses n8n, AI tooling, and smart alerting to stay ahead.
