• The AI tools of your choice
• Top-notch work equipment, including a MacBook and all the trimmings
• A Multisport card for staying active

You’ll collaborate with an international team working on digital products for global clients. We value openness, collaboration, and ownership, and we aim to create an environment where designers can focus on solving real product problems and continuously develop their skills.

Our clients include companies such as Zalando, IWC, Bidfood and Orderbird.

Zakres obowiązków

• Our clients increasingly come to us with one question: "How can AI help our business?" As a Senior AI Engineer, you'll answer it with working software, not slides. You'll improve both what we build for our clients and how we build it.
• In client projects across hospitality, retail, fintech and e-commerce, you'll bring real AI improvements into live products. You'll integrate LLM-based solutions with existing systems, and work through real-world constraints like data privacy, legacy systems and security reviews. You'll be part of our delivery process from day one: sprints, code reviews, automated tests, CI/CD and monitoring. You'll also run discovery workshops and build quick prototypes that show clients what's possible.
• Next to client work, you'll review how our teams develop software and introduce AI methods where they make a real difference. We want you to experiment, and you'll have a growth budget to do it. Test new models, tools and approaches, and bring back what works.
• Sharing knowledge is a core part of the role. Internally, you'll run workshops and demos so every YND engineer benefits. Externally, you'll be one of YND's public voices on AI: on our blog, at meetups and conferences, or on LinkedIn. You'll get dedicated time, a conference budget and our team's support for it.
