We are looking for you to strengthen our client FIND team in the Search domain, where they inspire their customers to easily find the right products. You will become part of a small, remote team where everyone is committed to finding the right balance between developing new, innovative products and further developing existing ones. You will work on the core product of the webshop, the search function, and support the team in conceptualizing and implementing its future-oriented direction.

• With your experience, you estimate and evaluate the effort required for complex features, taking into account technical requirements and business impact – always keeping the balance between technical excellence and economic added value in mind.

• You have already gained experience in implementing vector-based search systems in this field and are proficient in using language models to interpret search queries. Hybrid search approaches are also part of your repertoire.

• You already have experience with MongoDB and/or other NoSQL databases, AWS and Docker container technologies, and you also enjoy infrastructure work. 
• Your excellent communication and problem-solving skills make you a valuable team player, and you enjoy mentoring or coaching your teammates.  
• You are curious about new technologies, like to venture into unfamiliar territory, and quickly familiarize yourself with new topics.
