Job description

Hello, let’s meet!

Who We Are 

While Xebia is a global tech company, our journey in CEE started with two Polish companies – PGS Software, known for world-class cloud and software solutions, and GetInData, a pioneer in Big Data. Today, we’re a team of 1,000+ experts delivering top-notch work across cloud, data, and software. And we’re just getting started. 

What We Do 

We work on projects that matter – and that make a difference. From fintech and e-commerce to aviation, logistics, media, and fashion, we help our clients build scalable platforms, data-driven solutions, and next-gen apps using ML, LLMs, and Generative AI. Our clients include Spotify, Disney, ING, UPS, Tesco, Truecaller, AllSaints, Volotea, Schmitz Cargobull, and Allegro or InPost. 

We value smart tech, real ownership, and continuous growth. We use modern, open-source stacks, and we’re proud to be trusted partners of Databricks, dbt, Snowflake, Azure, GCP, and AWS. Fun fact: we were the first AWS Premier Partner in Poland! 

Beyond Projects 

What makes Xebia special? Our community. We run events like the Data&AI Warsaw Summit, organize meetups (Software Talks, Data Tech Talks), and have a culture that actively support your growth via Guilds, Labs, and personal development budgets — for both tech and soft skills. It’s not just a job. It’s a place to grow. 

What sets us apart?  

Our mindset. Our vibe. Our people. And while that’s hard to capture in text – come visit us and see for yourself. 

You will be:

  • designing, developing, and maintaining scalable backend services and APIs using Node.js and TypeScript, ensuring high performance and reliability,

  • architecting and implementing RESTful and/or GraphQL APIs as well as microservices-based solutions to support complex business requirements,

  • collaborating closely with cross-functional teams to define technical solutions, improving system architecture, and promoting engineering best practices,
