The Mill Adventure is a scale-up with the ultimate mission of building awesome products that will change the way the iGaming industry operates. We started our journey in 2019 with the vision of building a technology-driven organisation and creating a team consisting of the best of the best specialists in their respective fields.
Today, we provide a complete gaming platform for rapid deployment and success in iGaming. Our team of 100+ technology and iGaming experts is guided by a passion for invention, operational excellence and commitment to improving the inefficient.
We trust and value our team and strive to accommodate the right working conditions for each individual in remote, office-based or mixed models. We see the strength in being different and embracing the cultural diversity existing in our group.
One of our key strengths is our modern, event-driven , serverless technology stack , which allows us to innovate and move fast. As a Senior Security Engineer , you will be the cornerstone of our product and cloud security posture. You will own security across the code, the cloud,



the pipelines, the corporate estate, and the response when an alert comes in. You will design our security controls and then build them — our security team is small, and you will be one of three people, so there is nobody to hand a design to. That cuts both ways: almost nothing stands between a good idea and it being live, and there is nowhere to hide if it doesn't get delivered. Security can't do everything alone, so you will spend real time with developers and architects — reviewing designs, threat modelling, coaching on secure practices — and your impact will be measured as much by what they build securely as by what you build yourself.
The role spans security engineering, IT security, security operations and a degree of offensive security. Breadth matters less as a checklist than as judgement: knowing which risks are real, which findings are noise, what to fix first, and — most import
