Senior Full Stack Developer
We're building a Trustpilot-style review and trust platform purpose-built for the iGaming industry - and we're looking for a senior full stack developer to join our small team in Ljubljana. We want someone to direct AI coding agents to build the platform, and own the verification that makes their output trustworthy. Your job is less "write the code" and more "decide what good looks like, get the agents to produce it, and prove it's correct and safe before it ships." If that sounds like the future you want to be early to, read on.
- Build a modern iGaming platform from scratch: review submission, operator profiles, user accounts, ratings aggregation, and a points/rewards system.
- Design and own AI systems for review quality enforcement, fraud detection, operator data automation, and personalized recommendations.
- Contribute to architectural decisions alongside an existing developer.
- Make sure the platform is crawler-friendly, readable to both humans and bots, follows SEO guidelines, and is designed properly from the start to allow scaling.
- Scale and fortify the product with dispute resolution services, engagement mechanics, AI-powered fake review detection and fraud prevention, a recommendation engine based on user behavior and preferences, automated AI pipelines for sourcing and maintaining data at scale, and robust security layers.
- Real engineering fundamentals. You can read code and judge whether it's correct, safe, and well-built. You can't verify what you don't understand. This matters more than years on a CV. (required)
- A verification instinct. Your first question about any code is "how do I prove this is right and safe?", not "does it run?" You know coverage is not confidence. (required)
- Clear thinking about tasks. You can break a goal into well-scoped pieces with checkable acceptance criteria: the raw material agents run on. (required)
- Genuine tool optimism. You're excited to build pipelines with coding agents, not just chat with a model, and you want to push how much of the work the workflow can carry. (required)
- Solid TypeScript + Next.js + PostgreSQL, with care for the things that bite: rendering untrusted content safely, error and loading states, accessibility, and types that actually catch mistakes. (required)
- Comfort in the plumbing: git, CI, REST APIs, and a willingness to learn Supabase/Fly.io if they're new to you. (required)
- Solid grasp of modern frontend architecture and best practices. (required)
- A background in ML, evals, or anywhere you've had to measure whether a system's output is "good enough" is a real plus. (nice-to-have)
- Fully remote, hybrid or office work environment, according to candidate wishes.
- Annual luxury team building events at exclusive 5-star resorts abroad.
- €5,000 travel allowance per annum to meet colleagues across the globe.
- International health insurance.
- International working environment with top industry professionals.
- A fast-paced start-up culture, with lean organization structure where people matter.
- Long term cooperation, personal and professional development.
BitStarz is an online casino that’s changing the way people gamble. Since day one, it’s had one step in the future, being the first online casino to allow both Bitcoin and fiat deposits and withdrawals. In 2018, it added more cryptocurrencies as cashier options, bringing on board Bitcoin Cash (BCH), Ethereum (ETH), Dogecoin (DOGE), and Litecoin (LTC). Showcasing state-of-the-art games and a truly global experience, BitStarz has become a mainstay within the European, Chinese, and Australian online casino markets. Not just competing, BitStarz has now also become an industry trendsetter, as it’s helping cryptocurrency casino play make its long-awaited break into the mainstream. More than 3,600 games, 24/7 customer support, various language options, and huge promotions all combine to make BitStarz an unstoppable force. Its impressive credentials have even seen it earn plenty of critical acclaim in recent years, being nominated for two EGR Awards, winning Best Casino 2017 and Players' Choice 2018 at the AskGamblers Awards. While other casinos have followed the cookie-cutter path to success, BitStarz has branched out on its own, creating a unique platform that has proven to be a smash hit with players. With bonuses bigger than a Wall Street banker's, and cashouts faster than the Lightning Network, few can deny that BitStarz “Dream Big, Win Bigger” ethos has made it an industry mainstay.
