Security Engineer

Sisu Group is a fast-growing iGaming startup with over 180 team members and offices in Tallinn and Malaga. We are on a mission to redefine the future of iGaming and sports betting by building cutting-edge technology and next-generation player experiences. In 2024, two brands were successfully launched. Backed by €21M in secured funding, the majority of our company is owned by the people building it, our team. Sisu promotes a collaborative, non-corporate culture, offering competitive salaries with stock options to match.

• Solid cloud security knowledge (AWS or GCP)

• Comfortable with SIEM, log analytics, and detection tuning

• Experience with vulnerability management and incident response

• Strong scripting / automation skills

• Good written and spoken English

Nice to have (but not required):

• Experience in iGaming, fintech, or another regulated industry

• Exposure to MGA or Estonian Gambling Act expectations

• Threat modeling and secure SDLC experience

• Relevant security certifications (e.g. OSCP, Security+, cloud security specialty, ISO 27001 LI/LA)

What we use:

• Major cloud provider, cloud-native architecture

• Containerized workloads on a managed orchestrator

• Modern SIEM, log aggregation, and observability stack

• Static analysis and infrastructure-as-code scanning in CI

• Centralized vulnerability and finding management

• Git-based source control with modern CI/CD
