Joining SOFTSWISS means working where technology leads the way. Our software ecosystem powers award-winning platforms for online casinos, sports betting, affiliate management, and more – all supported by a high-performance tech stack designed for speed, scalability, and compliance across jurisdictions.
In our daily work, we rely on a diverse set of technologies, like Kubernetes, Kafka, Go, Ruby on Rails, React, ClickHouse, and PostgreSQL to solve complex challenges – from high-load game logic to real-time data streaming and multi-regulation support.
Get an inside look at how we work – from the technologies we use to the culture that shapes our engineering teams, and the real-world challenges we solve every day.
Our Approach to Technology
At SOFTSWISS, we make technology decisions carefully, balancing business needs with long-term technical quality. Every solution starts with precise requirements, thorough evaluation, and peer review by our architecture team. Performance, scalability, fault tolerance, and adaptability always stay in focus, combining proven industry standards with in-house expertise where it adds the most value.
We choose technologies based on their ability to solve real business challenges. For instance, Ruby on Rails powers many of our MVP products. This allows for quick product delivery with small, efficient teams. We use Golang, which is great for handling large data volumes and scaling well for high-load services. We have switched from Angular to React on the frontend, which gives us more flexibility, modern tools, and strong community support.
Our infrastructure mixes service-oriented architecture with monolithic elements in some core products, while others fully use microservices. Engineers experiment safely in staging environments or through controlled production rollouts with clearly defined rollback plans.
Recent seamless deployments include migrating to a new Kafka cluster, shifting parts of our infrastructure to Oracle Cloud, and splitting services for improved performance.
SOFTSWISS Current Tech Stack
We build our products on a robust, scalable, and well-tested technology stack that supports rapid delivery and long-term growth. By using open-source technologies, we keep full control over our infrastructure, avoid vendor lock-in, and lower costs compared to fully managed cloud solutions. This method lets us deploy on any cloud platform or traditional data centres, providing flexibility in the highly regulated, multi-jurisdictional iGaming market.
Let’s dive into the key areas and closely examine what our specialists are working with.
Backend
We use Ruby on Rails to accelerate product development. It allows us to deliver fully functional products quickly and iterate efficiently. For high-load, data-intensive services, we rely on Golang. Its concurrency model, efficient resource usage, and scalability make it ideal for processing large volumes of transactions and data in real time, ensuring the stability and responsiveness of our products even under heavy loads.
Frontend
We have standardised on React for frontend development. Its flexibility, reusable component structure, modern ecosystem, and strong community support allow us to build responsive, maintainable, scalable user interfaces across multiple products. React makes teamwork easier and speeds up feature delivery while keeping the codebase clean and easy to adjust.
DevOps & Infrastructure
- Kubernetes (K8s) powers our container orchestration, enabling us to scale workloads easily and run services reliably across multiple environments.
- Cloudflare provides security, DDoS protection, performance optimisation, and edge computing capabilities via its worker services.
- Nginx is a high-performance web server and reverse proxy that efficiently handles large volumes of HTTP traffic.
- RabbitMQ and Kafka manage asynchronous processing and high-throughput message streaming across distributed services.
- Redis is used for caching, improving performance and reducing latency.
- PostgreSQL is our primary relational database. We chose it for its reliability, rich feature set, and strong open-source community.
- MongoDB and other NoSQL solutions are used where flexible, document-based storage models are required.
Data & Analytics
Data transparency, compliance, and performance monitoring are essential for our products. For that purpose, we use:
- ClickHouse for fast analytical queries on large datasets
- Delta Lake supports batch and streaming data pipelines for reliable data lakes with ACID compliance
- Tableau for data visualisation, reporting, and supporting business decision-making
- Apache Spark for large-scale distributed data processing
- Amazon S3 for reliable, scalable object storage
QA & Automation
We extensively use automated testing to ensure product stability and release quality. Our QA automation frameworks are primarily built in Java, enabling consistent and scalable automated testing across backend services and frontend interfaces. This ensures we maintain high release velocity without sacrificing product reliability.
AI Technologies in Development
We are actively integrating AI-powered development technologies into our workflow. We use various models from leading commercial providers like OpenAI, Claude, and Google. Our toolkit also includes development environments such as Cursor and WindSurf.
We enhance and automate development and technical support processes through the Multi-Agent Collaborative Programming System (MCPS) and other AI-driven tools based on multi-agent systems. Team members can access these AI technologies, tools, and advanced development methodologies.
Engineering Life at SOFTSWISS
At SOFTSWISS, engineering culture is built on trust, ownership, and open collaboration. Each team defines its approach to code reviews while following company-wide automated rules for style, internal standards, and minimum approvals. For larger technical discussions, we have dedicated platforms:
- TED – internal talks where engineers share knowledge, present conference insights, or discuss topics relevant across teams.
- Architecture Committee – where critical architectural decisions are reviewed and approved.
- Platform Tech Lead Sync – a regular forum for technical leads to share updates, discuss challenges, and align on technology choices.
We encourage engineers to propose new tools or improvements at any time during 1:1 meetings with their managers or during leadership syncs, where proposals are reviewed and voted on collaboratively.
Career growth at SOFTSWISS is highly flexible. Engineers can pursue management roles as Engineering Managers, specialise as Architects or Tech Leads, or join the Tech Studio to focus on complex technical challenges. Internal mobility is also supported – engineers can move between teams when new opportunities or personal interests arise. Trial periods help ensure smooth transitions into new roles, with ongoing support from leadership.
We introduced a dedicated Grow Day within each sprint to support continuous learning. This initiative helps engineers invest time in personal development, reducing burnout while increasing participation in internal knowledge-sharing events like TED talks. Over time, Grow Day has evolved to include mentoring sessions, knowledge transfers, and strategic team syncs, while preserving its original goal – creating growth and delivery space.
We regularly share knowledge internally and externally – most recently at the SOFTSWISS Internal Tech Conference in Warsaw, where in-house experts presented real-world insights on AI, backend scalability, and microservices. Our engineers also speak at international events like Reflect Festival, Code Europe, Sentech Africa Tech Week, Hack of Tomorrow.
Conclusion: Step into the Tech Core of SOFTSWISS
Technology isn’t just a tool for the SOFTSWISS brand – it’s the foundation for building, scaling, and innovating in one of the most demanding industries. Our engineering teams work with modern technologies, make meaningful technical decisions, and contribute directly to the success of products used by millions of players worldwide.
