Job description

ABOUT THE ROLE

We are looking for a hands‑on Senior Application Security Engineer to become a founding member of our security team. You will be joining a highly regulated iGaming environment where uptime, data integrity, and user trust are paramount.

You will shape the security of our consumer‑facing platforms and of the cloud infrastructure they run on, balancing compliance requirements with the agility our business needs to grow.

Why Join Us?

• Impact: Be a founding member of the security team, helping shape our application security practice and tooling from the ground up.
• High‑Stakes Challenge: Work in an environment where security directly affects user trust, real‑time operations, and the bottom line.

YOU WILL BE RESPONSIBLE FOR:

• Secure the Development Lifecycle: Embed security into every stage of how we build software, from threat modeling at design time to security review before release. Partner with engineering to make secure‑by‑default the path of least resistance.
• Audit Web & Native Applications: Drive and run security testing and code review across our web and mobile apps.
• Protect the API Surface: Review and harden the APIs powering our platforms with focus on authorization and abuse prevention.
• Defend the Perimeter: Manage and tune our WAF and DDoS mitigation. You understand that in our industry, availability is revenue.
• Secure Cloud Infrastructure: Help harden our cloud environment where it matters most for application security.
• Automation & Scripting: Automate security checks, reduce manual toil and ensure consistent controls across our pipelines and environments.
• Compliance Support: Act as the technical bridge for regulatory and ISO certifications.
• Business Partnership: Work closely with engineering and product teams. You will champion a "Security by Design" culture, helping stakeholders understand risk without acting as a blocker to innovation.
• Strategic partnership: Driving our collaboration with Google to architect the future of our AI workflows and security frameworks.

OUR SUCCESSFUL CANDIDATE WILL HAVE THE FOLLOWING:

• AppSec Specialist: You have a strong background in securing high‑scale, consumer‑facing applications across mobile and web. You know the OWASP Top 10 cold and have opinions about what it leaves out.
• Code Reviewer: You can read and audit code in modern high‑level languages and use automated tools.
• Networking Native: You have a deep, foundational understanding of networking protocols (TCP/IP, DNS, HTTP/S, TLS). You aren't just a cloud user; you understand how packets move and how to secure them at the protocol level.
• Cloud‑Comfortable: You have working knowledge of cloud security, Kubernetes, and the trade‑offs of running microservices at scale.
• Regulated Background: You have thrived in industries with strict compliance requirements (iGaming, Fintech or Healthcare) and understand the rigor required.
• Scripting Skills: You automate security workflows with Python or similar.
• Pragmatic Communicator: You weigh business goals against security risk and can explain to non‑technical stakeholders why a control matters.
• Provider Management: Experience evaluating, onboarding, and managing external security vendors or managed service providers. You know how to get real value out of third‑party partners.

At the core of LeoVegas Group is Team Leo. Our culture is our foundation and is what enables us to innovate, build and lead as we trailblaze our way through the iGaming industry.
