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.
