Job description

Some companies talk about AI.
Others actually build it.

If you like technology to have a real impact – here you will see your code talking to thousands of people every day.

Literally.

Hi! We are KODA.

Our proprietary AI platform combines voice, chat, and process automation. Every day it handles hundreds of thousands of interactions. And none of them are random. We work with the biggest brands in Poland, including Żabka, Biedronka, Santander Consumer Bank, and many others (which you can see here ).

If you are looking for a place where your code genuinely influences the product, technology, and the direction AI is heading – we are on the same side.

Who are we looking for?

A person who has a strong technical background but can look broader – understands the product, the user, and the team. Someone who can plan their work, make technical decisions, and consistently deliver tasks. Someone who likes to have an impact and can translate it into working solutions.

What do we pay attention to?

• Minimum 5 years of experience in web application development.
• Very good knowledge of Vue.js, TypeScript, Node.js.
• Experience with Google Cloud Platform, Docker, CI/CD, REST API.
• Practical knowledge of clean code, tests, documentation, and automation.
• Understanding of system architecture and the ability to make design decisions.
• Experience working with LLMs, RAG, context engineering.
• Awareness of model and data security issues.
• Attention to performance, cost, and scalability of solutions.

Soft Skills:

• Clear Communication – you can explain complex things simply.
• Proactivity – you don’t wait for tasks, you propose solutions.
• Decisiveness – you know how to say “no” and justify a “yes.”
• Collaboration – you build understanding between different areas (Dev, AI, Client).
• Mentoring – you share knowledge and ensure the team’s quality.

An additional advantage will be:

• Knowledge of Terraform, Kubernetes, Elasticsearch, Cloud Firestore.
• Experience with on-premise solution implementation.
• Work with the SIP protocol or audio processing.
• Experience in enterprise environments / system integrations.
• Designing and developing the architecture of platform modules.
• Creating and integrating GenAI solutions (LLM, RAG, prompt engineering).
• Collaborating with the CEO on technology decisions and product roadmap.
• Building admin panels and interfaces.
• Participating in the design and implementation of on-premise solutions.
• Participating in code review and developing best practices within the team.
• Contributing ideas for improvements, testing, iterating, and experimenting.

How we work:

• In-office, in a new location in the center of Wrocław.
• Fast, proactive, iterative – without unnecessary decision layers.
• AI is part of the development process, not an add-on.
• Cooperation based on trust, partnership, and open communication.

What we offer:

• Real impact on the product, architecture, and technical decisions.
• Space for testing, experiments, and implementing your own solutions.
• Salary range: 14,000 – 16,000 PLN net (B2B).
• Projects for the biggest brands in Poland and innovative AI implementations for the public sector.
• A motivated team with experience and character – intimate and effective, where every decision truly makes a difference.
• Direct cooperation with the CEO and short decision paths.
• A culture based on courage, transparency, and partnership.
• Work with new technologies (LLMs, RAG, automation, proprietary platform) in the fastest-growing AI industry today.
• Modern office in the center of Wrocław (terrace, great coffee, zero dress code).
