Senior Full Stack Developer
Ljubljana (Hybrid) | Software Development
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.
Your challenges will include
- 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. We expect you to know which tools fit which problem, stay current with the space, iterate on solutions as better options emerge, and not be afraid to use new tools when they're the right call.
- 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.
Requirements
- 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.
- 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.
- Clear thinking about tasks. You can break a goal into well-scoped pieces with checkable acceptance criteria: the raw material agents run on.
- 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.
- 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.
- Comfort in the plumbing: git, CI, REST APIs, and a willingness to learn Supabase/Fly.io if they're new to you.
- Solid grasp of modern frontend architecture and best practices.
- A background in ML, evals, or anywhere you've had to measure whether a system's output is "good enough" is a real plus. That mindset is exactly what verifying agent output demands, and you'll have data scientists alongside you who think the same way.
We offer
