The Role

This role can be located remotely in Spain, Germany, The Netherlands, United Kingdom or Ireland.

Join us to shape the future of software in the underserved and high-impact HR technology industry. Your work will have a direct and tangible impact on customers, offering ownership and the chance to make a meaningful difference. As we prepare for significant growth, you'll face exciting challenges and have the opportunity to influence our path toward becoming one of the world's leading tech companies.

The Staff Security Engineer is a technical leader and force multiplier within Personio’s Security organisation. Operating primarily as a Right Hand and Solver, this role drives security strategy, shapes architectural decisions, and equips engineering teams to move fast - safely. A defining priority of this role is partnering with the Sr. Director of Security and broader organisation to build security capacity and leadership around Personio’s growing technical landscape, both as a capability to protect and as a tool to evolve our security services.

What You'll Do

• Serve as a technical pillar of the Security organisation - providing strategic and hands-on security leadership across the engineering organisation, influencing architecture, design decisions, and security posture at both the product area and org level.

• Lead Personio’s security response to the AI landscape - partnering with the Security leadership and partner teams to rapidly identify, assess, and reduce risks introduced by AI adoption, while defining durable security standards for AI-powered systems and data flows.

• Drive new technologies adoption within the Security organisation itself - identifying and championing opportunities, such as leveraging AI tooling, to mature, scale, and modernize Personio’s security services, from detection and response to secure-by-default developer tooling.

• Act as a cross-functional Solver and Tech Lead to the Security leadership - joining short-lived strategic initiatives, authoring and reviewing RFCs with a security lens, and translating complex organisational risk into pragmatic, actionable technical guidance for product and platform teams.

• Pivoting to bring security early to new top-level initiatives of the engineering organisation - drawing on deep expertise to shape secure-by-design patterns for a variety of technical topics as Personio continues to scale.

• Mentor and raise the security engineering bar - serving as a visible role model and multiplier for engineers up to Lead level, contributing to hiring decisions, and building a culture of security craftsmanship and continuous improvement across the engineering organisation.

What you need to succeed

• 10+ years of security engineering experience with a proven track record of technical leadership across large-scale, cross-functional initiatives.

• Deep expertise in cloud-native security, AWS environments, and DevSecOps practices - including automation of security controls and compliance at scale.

• Practical understanding of AI/ML security risks and appetite to develop fluency in AI-augmented security tooling and practices.

• Demonstrated ability to translate ambiguous, complex problems into clear technical strategy and actionable guidance for engineering teams.

• Strong communicator who thrives in cross-functional environments and can bridge security concepts for both technical and non-technical stakeholders.
