We will never ask for money or contact you through random texts. For more information, visit our careers blog. Please read: 1. This is a software engineering role. We are looking for applicants with minimum 5 years of software engineering experience, with a particular background in TypeScript. While we are building software on top of LLMs, this is not a machine learning role. 2. This role is remote (France, Spain, Italy, Poland, Germany) but can also be office-based (hybrid) in Barcelona, Paris, Milan, Munich or Cairo. We're looking for a Senior Fullstack Engineer (Applied AI) to join one of several exciting product initiatives currently in progress that leverage the latest in AI, particularly using Large Language Models (LLMs). One example project is extending our AI CoPilot product (currently only available in Heap) to more surfaces, allowing users without expertise in product or digital experience analytics to answer their questions simply by asking them. We are moving rapidly  to leverage LLMs to reduce time to insight, make setup easier, and much more. As our next Senior Software Engineer (Applied AI), you will be focused on product development, with a side of early product iteration. For example, we expect engineers to participate in user interviews as we validate product hypotheses. This is an exciting opportunity to work in a “startup within the startup.” We move quickly from idea to proof of concept to interview to product, ensuring that what we build provides actual value to our customers. As LLMs and the related technologies are growing and changing rapidly, we are enthusiastic about new ideas and libraries but discerning – what we build is foundational. We're a distributed team that operates across the US and Europe. We're open to hiring the right person anywhere within the US East Coast time zone or Europe.
