We know you’re much more than a few performance metrics. At Green Island, we strive to create an empathetic environment that prioritizes your well-being.

At the center of Green Island are six core values that help our decision-making and inspire us to be the best versions of ourselves.

We foster a collaborative work environment in which we are always pushing each other to be the best versions of ourselves.

For us, the client is never far removed. We focus on delivering a quality and functional product to our customers.

We strive to be an inspiration for one another. This enfolds learning new things and consistently stepping outside of our comfort zone.

Quality solutions for online and physical casinos

We encourage you to be creative in solving today’s problems and predicting tomorrow’s.

We take great pride in having a nonhierarchical model where each opinion is equally valued, regardless of seniority.

Life at Green Island

Build the player apps, platform services, data systems, integrations, and casino-floor software behind regulated gaming. Ship often. Stay close to the outcome.

Build what millions of transactions depend on.

Role

Team leads set direction. The person closest to the problem makes decisions, brings the right people together, and follows the work into production.

Take the problem from first question to production—and stay responsible for what happens next.

Own the outcome

Prefer working software, short feedback loops, and decisive action. Protect the foundations that keep us moving.

Move fast

What you get

Set a high bar. Challenge ideas directly. Make the people around you better.

Work with strong people

Freedom to move. Ownership to deliver.

Connect staff, daily operations, slot machines, and cash-handling devices in one product designed around the physical casino floor.

Deposit machines

Give staff one purpose-built system for the work that keeps the floor running.

Casino operations

Slot machines

Connect withdrawal devices and keep their activity visible.

Withdrawal machines

Give the team one operational view while software and connected devices keep the floor moving together.

One connected view of your entire casino floor.

Purpose-built software for managing physical casino operations and connected devices.

Casino Control

Casino Control is not an online product with floor features attached. It is standalone software whose workflows begin with physical operations and connected devices.

Built for the floor. Not adapted to it.

Our Sint-Niklaas engineers stay close to the people, operations, and connected systems their software supports.

Engineered close to the action.

Take control of every machine on the floor.

Name

Subject

Standalone software that connects casino-floor operations with slot machines and deposit and withdrawal devices.

Developers, designers, and customer-success teams work directly with operators. The same people who understand the problem help shape the answer, ship it, and keep it running.

Built by people who own the outcome.

We build the complete online casino product and separate software for physical casino floors—then stay responsible for both in production.

The team building what regulated gaming runs on.

Software for licensed operators, powering StarCasino Belgium, Hotwin, Madison, Casino King, StarDice, and StarSport.

Belgium

Green Island operates in the regulated Dutch market through StarCasino Netherlands.

The Netherlands

Green Island operates in the regulated Spanish market through Sol Casino.

Spain

Identity, limits, reporting, responsible gaming, and certification change at every border. Our product is built to change with them.

Built in Belgium. Proven across three markets.

Operators should not have to choose between software that stays reliable and a product that keeps moving. We build for both.

Make legacy gaming platforms obsolete.

The complete player and operator product across web, mobile, payments, games, Back Office, BI, integrations, and market-specific compliance.

Online Casino

Product decisions improve when engineers understand the real operation.

Stay close to the operator

Responsibility follows the problem through production.

Keep the talent bar high and the politics low.

Use short feedback loops without making reliability somebody else’s problem.

Move fast. Own the outcome.

One company. Two purpose-built platforms.

Player protection is product work. Limits, breaks, exclusions, monitoring, and interventions are built into each market experience—not added around it.

Build player protection into every interaction.

Send your question. We usually reply within 1–3 business days. Required fields are marked

Give us enough context to make the first reply useful.

Let’s build what’s next in regulated gaming.

See the open roles, the production problems, and the level of ownership waiting for you.

Careers

Company, media, supplier, or something else? We will get your message to the right person.

General enquiries

Tell us where you operate, what is holding the product back, and what success should look like.

Operators and partners

Choose where the conversation starts.

Our developers build and operate the complete product: React web experiences, React Native apps, .NET services, payments, data, integrations, regulation, Back Office, and BI. The problems are difficult. The ownership is real.

Claude, OpenAI, and Hermes Agent support investigation, implementation, and automation. Engineers still own the result.

AI in everyday work

Team leads provide direction, but people go directly to the person who owns a feature.

Direct expertise

Notice the problem, build the answer, coordinate across disciplines, and follow it into production.

More than assigned tickets

Automated tests, monitoring, redundancy, backups, penetration testing, feature flags, and clear ownership support frequent releases.

Frequent delivery

We use enough structure to run regulated systems responsibly. We do not want process to replace judgment.

Context over ceremony.

Green Island suits people who communicate clearly, take initiative, learn quickly, work across boundaries, and act without waiting for every next step to be assigned.

High freedom works with high responsibility.

Turn events and transactions into live operations, reporting, forecasts, segmentation, and decisions.

Data

Keep one configurable product moving across brands and markets without creating a fork for every operator.

Maintainability

Implement identity, reporting, taxation, responsible gaming, and player controls across three materially different markets.

Regulation

Process more than 20 million transactions daily while keeping player and operator experiences responsive.

Scale and performance

Difficult systems with visible outcomes.

A small engineering team owns a complete regulated gaming platform across web, mobile, .NET, data, integrations, and infrastructure.

Engineering at Green Island

SQL Server, MySQL, PostgreSQL, Redshift, distributed caching, pipelines, analytical projections, and near-real-time reporting.

AWS, containers, automated delivery, feature-controlled configuration, CloudWatch, New Relic, Sentry, and frequent production deployments.

Infrastructure

C#, modern .NET, APIs, event-driven workflows, event sourcing where audit history matters, and integration-heavy services.

Platform

React, TypeScript, React Native, TanStack tooling, Tailwind CSS, shared design systems, and exported design tokens.

Web and mobile

We are in the final stages of moving from .NET Framework to modern .NET while building new systems on a live platform.

Modern product work and meaningful modernization.

A small team owns the whole platform.

Regulated gaming combines high transaction volume, money movement, live experiences, external providers, market-specific rules, and constant product competition. A design that cannot survive production is not enough. Neither is a stable system that cannot change.

Fast, correct, and adaptable at the same time.

Boosts, missions, free spins, jackpots, tournaments, vouchers, calendars, and loyalty can be combined and reused.
