About the Company:
We are an early-stage iGaming technology company building a new cloud-native platform for real-money gaming from the ground up.
Our vision is to create a modern, scalable B2B platform that powers browser-based real-money games, operator integrations, wallet orchestration, back-office applications, reporting, audit and other core platform services.
As an early-stage start-up, we are building both our products and engineering culture from the ground up. Every technical decision, architectural choice and engineering standard has a direct impact on the future of the platform.
About the Role:
A hands-on senior role on the math behind our slots – building models, running simulations, validating the numbers.
Responsibilities:
- Turn a game brief into a working model that lands on its RTP, volatility, hit frequency, max win and feature targets
- Put the model through heavy simulation and check the statistics hold
- Break down how a game performs and call out what needs tuning
- Pair with backend engineering so the model runs in the build the same way it runs on your machine
- Act as a reliable second read on the team’s work – catch what slipped through, weigh in during reviews
Requirements:
- Slot math you’ve actually shipped, spanning more than one kind of mechanic and game
- A solid grounding in probability, combinatorics and statistics
- You write your own simulations and check your own models – in Python, JS/TS or similar
- A sharp eye for the small mistakes in a model, and the ability to explain the numbers to non-mathematicians
- A habit of reaching for new tools, AI among them, wherever they cut real time off simulation, prototyping or validation
Nice-to-have:
- Understanding of what certification demands in different markets
- Familiarity with how slot math lands on the backend, or comfort working alongside engineers
What we offer:
- Performance-based annual bonus
- Performance evaluation & salary review once a year
- 25 days paid annual leave
- Work from home option – 2 days weekly
- Flexible working schedule
- Additional health insurance – premium package
- Fully paid annual transportation card
- Fully paid Sports card
- Professional development, supportive company culture, and challenging projects
- Tickets for conferences and seminars
- Free snacks, soft drinks, coffee, and fruit are always available
All applications will be treated in strict confidentiality and only the approved candidates will be invited to an interview.
