What you'll do →Build and own the core product interface — document viewers, annotation layers, review workflows

→Design and implement APIs that connect AI systems to the front-end in a reliable, low-latency way

→Own the data layer — schema design, query performance, and data integrity in a compliance-sensitive environment

→Work directly with customers to understand how they work and translate that into product decisions fast

→Strong opinions on what AI-native UX should look like What we're looking for →Demonstrated experience shipping full-stack products end-to-end

→Product-minded — you think about the user experience, not just the implementation





→Shipped AI products (not exclusive to LLMs) — you don't need to build the models but you know how to build around them

→Ability to move fast without creating a mess you'll regret in six months

→Curiosity about hard, document-heavy domains with high accuracy requirements

→Experience in Pharma / Biotech a plus but, curiosity is more important Why Aldren Work with a lean team with deep experience in Pharma, AI, and building from 0 to 1. You will have a high level of ownership from day one and shape both the product and the business. Interested? Send us your resume and a note about what excites you about this role.
