Junior Data Engineer w Warszawa, Polska

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 .

At Tylko, collaboration and trust aren’t buzzwords — they’re how we work. From day one, you’re part of a team that makes real decisions and brings them to life together. You’ll have the freedom to share ideas, turn them into action, and shape the space around you literally. Here, learning isn’t a bonus. It’s part of the job.

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 Junior Data Engineer with strong SQL skills. In this role, you will help build the infrastructure needed to manage large volumes of data and support our data-driven culture. You will translate business needs into well-structured data models, ensuring our data is organised in a way that enables informed, data-driven decision-making across the company.

Your technical skills are as important as your communication skills. You will work closely with business stakeholders on a daily basis to understand their requirements and translate them into clear, effective data models and 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

• Monitor the performance, reliability, and cost-efficiency of our data pipelines and storage systems

• 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

• One Extra Day Off every month – because balance matters

• Private healthcare – take care of yourself, not just your inbox

• 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 your skills in an area that interests you (e.g. ETL, data governance)

• Fluent Polish and good command of English

• Working from our Warsaw office 3 days a week

Nice to have:

• Python

• Experience with any cloud platform (GCP preferred)
