About the role

  • You will help improve our existing ML-based products and build new features and services using LLMs.
  • A core part of the role is context engineering — designing the right inputs, retrieval strategies, and prompt structures to get the best possible output from LLMs in production.
  • You'll also contribute to our software engineering efforts when needed, bridging the gap between ML and software engineering on the team.
  • You will work in the Machine Learning Team, where we build LanguageWire's machine translation (MT) and adjacent services to monitor and predict its performance.
  • The team consists of ML Engineers, Analytics Engineers, and Full Stack Software Engineers.
  • You'll collaborate across these disciplines daily, and we value people who can move fluidly between ML experimentation and production engineering.
  • You'll report to the team leader.

Requirements

  • 2–3+ years of relevant experience from areas such as ML engineering, AI engineering, or software engineering with a strong ML focus
  • Hands-on experience with LLMs and prompt/context engineering — either professional or through substantial personal projects.
  • Experience with best practices and building production grade systems in Python. Knowledge of other programming languages is considered a bonus.
  • Experience constructing and evaluating experiments.
  • A strong analytical mindset — you think in terms of hypotheses, baselines, and measurable outcomes
  • A keen interest in the rapidly evolving LLM space and tooling.
Benefits
  • Enjoy flat hierarchies, responsibility and freedom, direct feedback, and room to stand up for your own ideas
  • Internal development opportunities, ongoing support from your People Partner, and an inclusive and fun company culture
  • International company with over 300 employees. Offices in Copenhagen, Aarhus, Stockholm, Varberg, London, Leuven, Lille, Paris, Munich, Hamburg,, Sophia Antipolis, Atlanta, Finland and Valencia
  • For this role, we have a full-time FlexiWire@home option for remote work. Of course, you are always welcome at the office to collaborate and connect with your colleagues.
  • We take care of our people and initiate many social get-togethers from Friday Bars a to Summer or Christmas parties. We have fun!
  • Excellent location in cool and modern offices in the city center, with a great rooftop terrace and a view over the Town Hall Square
  • Private health insurance
  • Working in an international environment—more than 20 different nationalities
  • A dog friendly atmosphere
  • Big kitchen with access to organic fruits, nuts and biscuits and coffee.
  • Social area and game room (foosball table, darts, and board games)
  • Bike and car parking
