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.
About Project
You will join a project centered around the evolution of an existing AI agent framework built in Go. The current system is based on a behavior tree architecture and plays a key role in how AI agents are designed and executed.
The primary objective is to modernize and enhance the framework, with a strong emphasis on performance, scalability, and architectural improvements. This role goes beyond routine development - it requires deep technical insight, the ability to work with an established codebase, and close collaboration with stakeholders to shape the future direction of the solution.
You will be:
analyzing and understanding the current behavior tree framework and its architectural foundations,
redesigning and optimizing the framework with a focus on performance, scalability, and maintainability,
building and enhancing AI agent capabilities using modern GenAI approaches,
collaborating directly with stakeholders to align technical improvements with business objectives,
driving best engineering practices, including clean architecture, testing, and code quality,
contributing to technical discussions, proposing improvements, and identifying risks,
working within a distributed, cross-regional team environment with partial overlap with the US East Coast team (3:00 PM - 6:00 PM CET).
Requirements
Your profile:
strong professional experience with Go,
hands-on experience with Generative AI (GenAI) technologies,
practical experience in building AI agents or agent-based systems,
ability to work with and modernize existing systems and codebases,
solid software engineering fundamentals (design, performance, scalability).
Nice to have:
strong analytical and problem-solving abilities,
excellent communication and collaboration skills,
ability to work effectively with distributed teams and stakeholders,
proactive mindset and ownership of technical solutions.
Work from the European Union region and a work permit are required.
