Job description

There are companies that talk about AI.
And then there are those who actually build it.

We implement AI assistants for some of the biggest brands in Poland.

If you're looking for real technical challenges and the chance to work on meaningful AI deployments at enterprise scale, including TVN, Żabka, Biedronka, Santander Consumer Bank, and many more .

For the past 7 years, we’ve been building our own AI platform that supports all communication channels: voice assistants on websites, SIP-based voicebots, email automation, social media messengers, and business systems.

We’re a small, experienced team with big ambitions. We move fast, stay sharp, and skip the layers that slow things down. And we’re looking for someone ready to bring their piece to the puzzle.

Who we’re looking for:

Someone who’s been a senior developer and a team leadand wants to stay close to the code.
Someone who understands what it means to work with a team. Who knows that sometimes things need to move fast but still make sense.
Someone who takes ownership, knows when to say “no,” and knows when to celebrate a win with the team.

You don’t need 10 years of “Tech Leading.”What you need is clarity, courage, and a real drive.

Our future Tech Lead:

• isn’t afraid of decisions and still enjoys getting into the code
• combines architectural thinking, client experience, and passion for AI
• can roll up their sleeves, design a system, present it to the client, and rally the team around a shared goal
• isn’t fazed by a call with the CISO of a major bank
• works hands-on, supports the team, and takes responsibility
• is proactive, creative, and always ready to test new ideas
• asks sharp questions, connects the dots, and follows through
• knows Generative AI is going to reshape the world and wants to be part of it, including things like RAG, model security, and context engineering

Which skills we’re after:

• experience working with LLMs, RAG, and matching solutions to real problems
• Frontend: Vue.js / TypeScript
• Databases: Elasticsearch, MySQL, Cloud Firestore
• “Vibe coder” mindset – proactive, fast, iterative, and thoughtful
• experience working with development teams and maintaining scalable architecture

Bonus points for experience with on-premise deployments,familiarity with SIP protocol,ability to lead technical RFPs or procurement processes.

What you’ll be doing:

Your role combines three key areas

• designing and evolving scalable, AI-first system architecture
• testing and deploying solutions involving LLMs, RAG, prompt engineering, and platform integration

Leadership (33%)

• building and managing technical documentation, overseeing code quality
• ensuring security in implemented solutions (including on-prem environments)
• helping shape the product roadmap

handling technical documentation for RFPs, joining client calls (including with their IT & security teams)

What we offer:

• Salary between 16 000 – 22 000 PLN net (B2B)
• 26 paid days off per year + public holidays
• Real influence on the tech stack, product, team development, roadmap, quality, and direction from day one
• Short decision-making paths (no need to get 3 approvals to move on something that makes sense)
• A space where your ideas, improvements, tests, and innovations are truly welcome
• A team with experience, character, and real skills
• Projects with real AI:LLMs, RAG, automations, and our own platform. You won’t just be plugging in someone else’s tools
• Collaboration with top brands across various industries
• Work alongside experts in web dev, devops, data science, and SEO (we’re part of a larger tech hub)
• A bright new office in central Wrocław: lots of natural light, a big terrace, and seriously good coffee
• No corporate fluff, no dress code
