Job description

Join Tylko, Where Design Meets Technology

Founded in Warsaw, Poland, in 2015, Tylko is redefining how we design, shop for, and experience furniture. Frustrated by mass-produced, one-size-fits-all solutions, the team created something smarter: bespoke storage that balances cutting-edge technology, premium craftsmanship, and sustainable production.

With millimetre-perfect precision, every piece is made-to-order and crafted locally, minimising waste and maximising longevity. The result? A new standard in furniture – one that fits your space, your style, and your life.

Why It Matters

We’re not just building furniture. We’re changing how people think about living with it. By merging technology and design, we help people create spaces that truly reflect who they are. If you believe that good design can make everyday life better, you’ll feel right at home here.

How We Work

We believe in small teams, big ideas, and simple processes. No endless paperwork, no silos. Just open communication, shared goals, and a healthy dose of curiosity. We start small, think big, and move fast, because progress always beats perfection.

AI is part of how we work - it's not an add-on here

We treat it like any other tool worth knowing: it helps us think, decide, and move faster. We're not looking for people who "know AI" - we're looking for people curious enough to rethink how they work altogether. You don't need to be an expert on day one - you need the drive to grow.

About the Role

We are looking for a Business Analyst with strong SQL programming skills. Your mission is to bridge the gap between technical data architecture and everyday business operations. You will translate business needs into well-structured data models that enable informed, data-driven decision-making across the company. You will build data models on your own.

The role requires a combination of analytical and technical skills, along with the ability to ask the right questions, identify key insights and draw meaningful conclusions to develop the right solutions.

What You’ll Do

You’ll take ownership, make things happen, and see your impact. Specifically, you will:

• Build and implement optimised data models that support business requirements and ensure data integrity
• Integrate data from various databases, APIs, streaming platforms, and files
• Troubleshoot data issues, resolve data quality problems, and actively reduce technical debt
• Partner closely with business stakeholders to translate their needs into actionable data solutions

Perks & Benefits

• One Extra Day Off every month – because balance matters
• Private healthcare – take care of yourself, not just your inbox
• Sports card – move, sweat, repeat
• Tylko discount – design your dream home, at a dream price
• Regular team get-togethers – we're serious about our memes and our integration events
• Dog-friendly office – four-legged coworkers welcome
• Best-in-class AI tools and time to master them – a modern, full AI stack, and real space to learn it; we invest in your fluency, not just your inbox

What we’re looking for:

• Strong SQL skills, allowing you to write and optimise complex queries
• Experience in data modelling
• Experience gathering requirements directly from business stakeholders - understanding the current situation and desired outcomes, then proposing an appropriate solution
• Strong motivation to further develop towards a Data Engineer role
• Fluent Polish and good command of English
• Working from our Warsaw office 3 days a week

Nice to have:

• Python
• Experience building reusable AI solutions, such as prompts, workflows, skills, or automations
