Research Engineer, Applied ML/AI at Sully.ai. Remote Location: US - Remote. About Us. π Team from OpenAI, DeepMind, NASA, GoogleX, Tesla, and 2 physicians: 6 exits, 2 IPOs.. π₯ Our model outperforms Claude, Gemini, and GPT-4.5 on clinical benchmarks.. π 400+ healthcare orgs signed in 16 months.. β‘οΈ $25M raised from YC, Amity Ventures, Sequoia scouts, and more.. π $1T+ market opportunity. Weβre going after all of it.. About the Role. We are seeking a Research Engineer, Applied ML/AI to bridge cutting-edge research and scalable production systems. This role will own training, fine-tuning, and inference toolchains, drive multimodal (text/audio/vision) integration, and optimize model throughput and evaluation in production. Youβll ensure Sullyβs research artifacts translate into stable, high-performance features that power our agents in healthcare.. Key Responsibilities. Own the full training, fine-tuning, and inference toolchains for Sullyβs applied ML stack.. Translate research repos into production-ready services behind stable APIs.. Ship multimodal features (text, audio, vision) that enhance agent performance.. Optimize inference pipelines for cost, throughput, and latency.. Build evaluation systems that integrate into CI/CD, blocking weak checkpoints.. Hard Requirements. Strong engineering background with experience in distributed systems and large-scale model training/serving.. Hands-on experience with multimodal ML (audio, vision, text).. Production ML hygiene: versioning, metrics, observability, reproducibility.. Proven track record of shipping ML systems into production.. Nice-to-Have. Experience with model optimization techniques (quantization, caching, pruning).. Background in healthcare, medical AI, or other high-stakes regulated environments.. Contributions to open-source ML frameworks or libraries.. First-Month Focus. Audit and streamline current training/fine-tune/inference pipelines.. Stand up evaluation frameworks that gate deployments in CI.. Deliver first improvements in throughput, cost, or latency of deployed models.. Success OKRs (90 Days). Deploy at least one multimodal feature (speech or vision) to production agents.. Reduce inference cost or latency by 30% through optimization strategies.. Integrate evaluation guardrails into CI/CD to block underperforming model releases.. Culture Fit. Persistent, driven problem solver. Willing to push back on leadership to defend quality/timelines. Thrives in high-ambiguity, fast-paced startup environments. Why Join .
