Python Backend Engineer (LLM Data Pipelines) | US AI Product

100% remotely (within Poland only) or in our office: Warszawa

Hi, Polcode here!

We’re a global, people-first software house matching ambitious developers with challenging projects. Our team of over 100 professionals helps build and improve digital businesses, software platforms, eCommerce stores, websites, apps, and everything in between. And they’re good at it.

We’re currently looking for a solid Mid/Senior Backend Engineer (Python) to join a long-term project for a US-based client building an innovative AI-powered platform for leasing agreements.

The product is already live and continuously evolving - this is not a greenfield project, but a growing system working with real users, real documents, and real data.

In this role, you’ll contribute to a key part of the platform responsible for extracting structured data from unstructured documents. The solution combines backend engineering, data processing pipelines, and LLM-powered workflows to turn complex document inputs into structured, usable data.

This role is ideal for a strong backend engineer who is curious about AI systems and eager to learn how LLMs can be used in real production pipelines.

Why this project is worth your attention:

• Long-term, stable project with no fixed end date
• AI-powered product with real business value (document intelligence for leasing workflows)
• Opportunity to work on LLM-powered data extraction pipelines used in a production environment
• Strong engineering focus - building reliable systems around AI rather than experimental prototypes
• Direct collaboration with experienced engineers and close contact with client-side technical leadership (CTO level)
• Small, focused international team (Poland + US)
• Production environment with real data, continuous releases, and ongoing product evolution.

Perks of being a #Polcoder:

• Multisport card, private medical care, life insurance, and meaningful gifts to celebrate important days
• Competitive salary with up to 20 paid days off (B2B) and development budget
• All the necessary equipment for comfortable work
• Professional onboarding process
• We respect your private life - no overtime, no weekend jobs, work-life balance only, promise!
• Work at times that suit your daily rhythm, from the place of your choice
• Your work is appreciated - we believe in the power of feedback, as well as the one you give us.

TL;DR

• 100% remote work
• 0% nonsense

We strongly believe that putting people first makes our work better.
We encourage you to grow your career, contribute to open source, and follow your passion. We wanna do great things with you! 💜
