Principal AI Engineer with .NET | EU

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 and AI solutions, and cutting-edge applications to shape the future of tech. Our clients include McLaren, Aviva, Deloitte, Spotify, Disney, ING, UPS, Tesco, Truecaller, AllSaints, Volotea, Schmitz Cargobull, Allegro, InPost, and many, many more.

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 support tech communities, 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

We’re seeking a Principal Developer to lead the implementation of AI and code-generation tooling across a broad portfolio of products, with a strong focus on software integrations.

This role combines hands-on engineering, technical leadership, and mentorship. You will shape engineering standards, guide teams working on complex systems, and influence technical direction-without direct line management responsibilities—while contributing directly to sprint delivery within the AI-enhanced integrations domain.

You will be:

• designing and evolving scalable, high-performance solutions within the AI-enhanced integrations domain,

• defining and enforcing coding standards, architectural patterns, and best practices across teams,

• reviewing code for quality, maintainability, and performance, leveraging the available tech stack and tooling, including AI-assisted development tools such as GitHub Copilot,

• mentoring and guiding engineers of varying experience levels, with a strong emphasis on AI-first engineering practices and integration design patterns,

• encouraging thorough and consistent documentation, including AI-supported validation where applicable,

• contributing hands-on to sprint goals through implementation of new features and ongoing maintenance,

• evaluating emerging AI and developer-tooling technologies and advocating for their adoption,

• collaborating closely with product managers, designers, and other stakeholders to translate business requirements into robust, intelligent, and automated integration solutions,

• staying current with advancements in AI/LLM integration, including prompt engineering and orchestration of APIs such as OpenAI and Azure OpenAI.

Your profile:

• bachelor’s degree in Computer Science, Data Science, Engineering, or a related field,

• strong experience with the Microsoft .NET stack, including C# and .NET Core,

• 2+ years of hands-on experience in AI/ML development, with an emphasis on generative AI and related technologies,

• proven ability to define engineering standards and software development processes supported by tooling that maximizes developer productivity and code quality (e.g. automated code analysis, documentation generation, code review workflows), including AI-powered tooling,

• experience mentoring developers and guiding technical decisions across multiple teams,

• solid understanding of CI/CD pipelines and automated testing practices; exposure to AI-assisted or AI-generated test cases and performance testing is a strong plus,

• familiarity with code-generation techniques such as Roslyn analyzers, source generators, or T4 templates,

• ability to collaborate effectively in a dynamic environment and balance multiple responsibilities,

• good verbal and written communication skills in English (minimum B2 level).
