We’re seeking Research Scientist Interns to join us in advancing the Learning Engine to build superhuman agents across domains.\nAbout the Role\nYou’ll partner directly with the founders to design, implement, and evaluate new algorithms that let agents learn continuously. Successful prototypes move quickly into production, so your research will have an immediate impact on real users.\nResponsibilities\nDesign and run state-of-the-art machine-learning experiments to extend our agentic Learning Engine.\nPublish results through papers, datasets, and open-source code.\nCollaborate with product and engineering to translate your research findings into the Learning Engine, delivering value to customers across diverse domains.\nQualifications\nPhD in AI, Computer Science, or a related field - or an equivalent record of research excellence\nPublications at top AI conferences (Neurips, ICML, ACL, …) or an open-source project with significant traction\nStrong Python skills and experience with ML frameworks such as PyTorch\nExceptional problem-solving ability; comfortable working independently and in teams\nFamiliarity with graph databases, vector stores, or Elasticsearch for structured-data retrieval\nKnowledge of advanced training algorithms (e.g., DPO, RLHF, GRPO)\nClear written and verbal communication\nWhat We Offer\nRemote-friendly setup - work from anywhere in compatible time zones, with our office based in London for in-person collaboration\nCompetitive, top-of-market compensation package\nFreedom to pursue ambitious research aligned with our mission\nClose collaboration with the founders and senior researchers\nLimitless cloud compute - GPU clusters and a war chest of cloud credits ready for your experiments\nConference travel, publication, and open-source support\nOption to extend to 6 months or transition to a full-time role\nIf you’re excited about creating AI that learns continuously and autonomously, we’d love to hear from you.","description_format":"text","description_chars":2438,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"phd","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[{"name":"United
