Open, depends on your expertise and experience
Your next professional challenge awaits you in one of Barcelona’s top tech hubs.
Your new company
One of the leading electronics retail companies in Europe is looking for a new developer for the webshop’s chat and voicebot development project.
Your new role
- You take on a responsible role in the development of our Customer & Marketing web applications and the associated backend services.
- You play a key role in defining requirements and solution approaches in collaboration with Product Owners.
- Together with your team, you take responsibility for the services and applications of the team and ensure both maintenance and operation within our cloud infrastructure. Continuous improvement is important to you.
- You enjoy sharing your knowledge with your colleagues and thereby contribute to the development of the entire team.
- You work on the integration and connection of Large Language Models (LLMs) and use frameworks like LangChain to develop innovative (generative) AI solutions.
- You will work with:
- Infrastructure: Terraform, Kubernetes, GitOps with Flux, Github Actions (CI/CD), Docker
- Google Cloud Products: Dialogflow CX, Cloud Storage, BigQuery, GKE (Kubernetes), Cloud SQL, Vertex AI
What will you need to fit in it
- You have at least 4 years of professional experience as a Frontend or Full-Stack Engineer and have already built and operated your own applications in the past, ideally in the e-commerce environment.
- SPAs are your first choice when it comes to implementing applications with React and the latest TypeScript standards.
- In case you are a Fullstack for the backend they expected to see Node.js.
- The quality of your application is important to you, which is why you swear by TypeScript and prefer to test every line of your code.
- You have experience in NoSQL databases (like MongoDB) as well as in relational databases (PostgreSQL)
- Since you are interested in the entire lifecycle of an application, Continuous Delivery and (cloud) infrastructure are not foreign words to you, and you prefer to combine this with microservices.
- Codebases you have worked with have led you to consider a monorepo approach.
- You are interested in chatbot and voice solutions, especially the intricacies of NLP, and ideally have already gained initial experience with services like Google Dialogflow.
- You have experience in connecting and using Large Language Models (LLMs) and are familiar with frameworks like LangChain.
- You are curious to implement the latest AI trends with us (RAG with vector search, Agentic AI and Multi modal AI)
- You have a strong team spirit, are used to working in agile teams, and have no problem with freedom and responsibility.
