Hi there! We’re Tooploox, a Solvd Inc. company.

We create AI-powered products and services that make a real difference. Our team of nearly 200 specialists - including a 50+ person R&D team with many PhDs - has pioneered AI solutions across industries from healthcare to e-commerce. We’ve published research in top-tier venues like NeurIPS and ICML, while delivering real-world applications that help our clients innovate and scale.

Now, as a Solvd Inc. company, we’re building on our strengths with even greater global reach and resources — while keeping the creative, human-scale culture that defines us here in Poland. If you want to work on meaningful AI projects, with space to grow and the freedom to innovate, you’ll feel right at home.

We’re on the lookout for a Senior AI Research Engineer to take on a pivotal role in our team, working with our biggest client. The Responsible AI team at eBay is committed to ensuring fairness, transparency, and accountability in AI systems. We work cross‑functionally to embed Responsible AI principles into eBay’s AI / ML models, providing tools, documentation, and best practices for ethical AI development.
