Hybrid Full-time
You’ll join AI Engines – the team building the backend “brain” of AI Agents in Text App.
These aren’t your average scripted bots. Our AI Agents understand context, communicate naturally, and take meaningful actions: from digging through the Knowledge Hub to answer customer queries, to guiding human agents, or triggering automations in third-party tools via Copilot.
To make this happen, we need to design highly scalable backend systems capable of handling millions of conversations daily. We build the APIs, develop the reasoning layers, and continuously push the boundaries of what our agents can actually do.
Hands-on building, scaling, and maintaining the core backend architecture (Vector Database, AI Engines, Knowledge Hub, etc.).
Designing and implementing an Agentic reasoning and orchestration layer using Skills and tool calling (a core building block of our architecture).
Modernizing the core by taking full ownership of migrating legacy implementations into our modern, highly scalable AI ecosystem.
Collaborating with our AI researchers to experiment with, validate, and confidently push new AI features straight to production.
Mastering Context Engineering & R&D by moving way beyond basic prompt engineering. You'll be experimenting with and optimizing how our agents communicate with LLMs (taking full ownership of multi-turn conversations, tool calling, advanced RAG integrations, system prompt design, and history management).
Designing RESTful APIs and service integrations for AI and data-heavy use cases, while migrating legacy implementations to a modern ecosystem.
Integrating AI Agents with MCP servers, shaping how they interact with external ecosystems.
Setting the standard by taking an active part in architecture discussions, code reviews, and technical decision-making, while bringing an extreme ownership and "fast flagging" mindset to the team.
Have 6+ years of experience in backend development, with strong, recent, hands-on expertise in Node.js and TypeScript in recent projects. We need someone who is fluent in async programming, queues, and streams, and can jump into our codebase on Day 1.
Have hands-on experience with real-time communication (WebSockets, async service-to-service messaging).
Have proven commercial experience building AI-driven features. You don't just know the concepts—you’ve actively implemented RAG, Function Calling, and Agentic systems in production.
A deep understanding of Context Engineering. You know that it’s no longer just about "writing good prompts." You have proven experience managing context windows, multi-turn conversation history, and tool calling within Agentic or RAG ecosystems.
Have a solid grasp of database ecosystems, including SQL (Postgres), NoSQL (Elasticsearch), and Vector Databases (e.g., Pinecone, pgvector), along with the mechanics of embeddings.
Know how to run and scale services on Google Cloud Platform and Kubernetes.
Enjoy solving complex technical challenges in microservices, concurrency, and performance optimization.
Experience with Go (Golang) is a strong plus.
Have experience building Data Pipelines or ETL processes.
Previous work on SaaS products, low-code/no-code platforms, or workflow automation.
(Let’s be transparent: while we value curiosity and a growth mindset, solid hands-on experience with Node.js and TypeScript is a strict requirement for this role. We are happy to give you time to learn our specific AI frameworks and databases on the go, as long as your core backend skills are top-notch.)
Core (Must-have): Node.js, TypeScript
Databases: PostgreSQL, Redis, ElasticSearch
Scalability & communication: PubSub, Webhooks, SSE
AI-related: LLMs, LangGraph, Function Calling, Context Compression, MCP (Model Context Protocol)
Infrastructure & deployment: Docker, GitHub Actions, Prometheus, Grafana
Testing & reliability: Vitest, Supertest, Playwright
We’re a hybrid team – remote when it makes sense, onsite when it matters most.
Once per quarter, your whole team spends 5 working days together at our Wrocław office – a time for focused execution, unblocking work, and driving key outcomes.
Our office is open year-round – drop by anytime.
Contract: B2B (self-employed). You’ll need a registered business in selected EU countries — either already set up or possible to register in your country. Please apply only if this works for you.
We don’t want you to worry about all the basic benefits - like a Multisport card, private health care, or a home office equipment budget.
What we really want you to feel and what we believe in is that the real benefits come from the culture we’ve built.
With a hybrid work model, unlimited paid days off and sick days policy, an environment focused on outcomes instead of worked hours, and people dedicated to their work, you’ll find a workplace where you can thrive.
And here’s the icing on the cake: you’ll have the opportunity to work with the makers behind all Text products: LiveChat, ChatBot, HelpDesk, KnowledgeBase, OpenWidget.
Recruitment process
It’s time to fill out the application form and attach your CV. Here’s what happens next in our fully remote recruitment process:
Get yourself something to drink and let’s talk. Tell us about your professional experience, the results of your work, and your values. We’ll tell you a little bit about the company, products, and company culture. We’ll also talk about the money and your availability.
At this stage, we’ll test your craft to see the value you can bring to the company. The most important part? You’ll find out everything about the challenges in your role, and we’ll find out everything we need to know about your experience.
We’ll give you a project to work on for a few hours. You’ll also meet the people that’ll give you tips, advice, and access to data and tools so you can feel like you’re already a part of the team. Get familiar with our atmosphere, the workflow, and the people. All in all, we’ll help you make a well-informed decision.
