We're looking for a full-time Senior LLM Fullstack Developer to drive complex architectural decisions, mentor junior developers, and build scalable, production-ready LLM applications.
You’ll support our team remotely with availability either during the Eastern Time (EST) or European (EU) business hours, with the option to work onsite or hybrid from our Vienna office if you’re based nearby.
You’re an ideal candidate if you meet the following requirements:
You have a solid foundation in Node.js, TypeScript, and Full Stack frameworks like Next.js or Remix, using them to build scalable and maintainable applications, including server-side logic and optimizing back-end performance for LLM-based applications.
You have hands-on experience or a keen interest in Retrieval-Augmented Generation (RAG) architectures, LangChain, and LangGraph to orchestrate LLM workflows, leveraging embeddings, vector databases, and memory-efficient techniques. You have built and deployed RAG-pipelines in production applications.
You thrive in an environment where you can prototype quickly, explore emerging AI tools, and embrace failure as part of innovation, while also having the resilience to refine and ship production-ready applications.
While TypeScript & JavaScript are your primary language, you’re comfortable with Python for data analysis, LLM fine-tuning, and integrating AI toolkits into scalable applications.
You take pride in your work, feel ownership over your projects, and proactively identify roadblocks before they appear. You challenge ideas, bring solutions, and lead development with confidence.
We love experiments and learning new stuff. You'll have a yearly budget to buy books, check out online courses or attend conferences.
Every week half of the team gets the Friday day off. So every other week you either work or train the new skateboard trick.
Yes, we still have an office in Vienna and there is free beer, a foosball table, and a dog to pet. As part of Residence you also have the option to work from other offices like New York, LA or Sydney.
That's right, everyone who has been with us at least a year gets to share in our success!
Besides all of this remote stuff, Vienna is still the most liveable city in the world. So if you fell in love with Vienna and our space (who wouldn't) we'll help you with a flight, accommodation for the first week of your arrival, help with the Visa and find you some new best friends.
We are a Virtual First company, so you choose where you work from. To support your adventures in Paraguay, Italy or Fiji or just your wifi costs at home, you’ll receive a remote work bonus.
Annual retreats (like this), monthly activities, cake wednesdays, and who knows what else.
You'll work with an extremely talented team like Edo or Simone
You have experience with Supabase, Redis, or PGVector for AI-driven data retrieval.
You’re comfortable setting up and deploying LLM applications on AWS or Azure, optimizing cloud resources for scalability and performance.
You have an eye for good UX and love developing interactive AI-driven experiences that balance performance, usability, and cutting-edge AI capabilities.
Share your story and past experiences. We can't wait to get to know you better!
