Agent guide: [/agents.md](https://www.wearedevelopers.com/agents.md). --- # Senior AI Engineer - **Company:** Doctronic Inc. - **Location:** San Francisco, CA, United States - **Experience:** Expert - **Salary:** $200,000.0 - $300,000.0 - **Contract:** Permanent contract - **Skills:** Training Data, Artificial Intelligence, Program Optimization, Routing, Performance Tuning, Software Safety, Reinforcement Learning, Fast Healthcare Interoperability Resources, Large Language Models, Model Validation, Electronic Medical Records, Health Level Seven International, Build Tools, Machine Learning Operations, Data Generation - **Published:** September 16, 2026 - **Apply:** https://www.indeed.com/viewjob?jk=1cf03d094e171ec3 ## About the Role * You are a research-minded engineer who wants to build intelligent systems and is equally serious about understanding and demonstrating their effectiveness. * You have deep experience in at least two of the following: + Agentic architectures, reasoning systems, and tool use + Model evaluation, experimentation, and rubric design + Model training, fine-tuning, distillation, or reinforcement learning + Search, ranking, retrieval, or RAG * You have strong ML fundamentals, including training data, objectives, metrics, failure analysis, calibration, and validation. * You're comfortable working in domains where ground truth is incomplete, and experts disagree, and where the right move is sometimes to question what "correct" even means before answering. * You think through the business impact of your work and scope and prioritize solutions accordingly. * You have strong engineering fundamentals, you build real systems, not just notebooks or one-off experiments. * You communicate clearly and collaborate well across engineering, clinical, and product teams. Typically, candidates will have an advanced degree in a quantitative, computational, or scientific discipline and 3+ years of highly relevant applied or research experience in AI/ML; or 7+ years of relevant experience building and researching ML systems, including recent hands-on work with LLMs and generative AI., * Experience building AI systems at an early-stage or high-growth company * Experience in healthcare, clinical AI, or another regulated or safety-critical domain, including familiarity with clinical workflows, healthcare data, or standards such as HIPAA, FHIR, EHR, and HL7 * Experience with human-feedback systems, RLHF, simulation, or synthetic-data generation * Work in AI safety, bias detection, calibration, or fairness ## Description Doctronic runs a real clinical practice, with patients consulting our AI doctor every day. That gives us a dataset no one else has to test ideas against. We're committed to publishing and open sourcing as we go. You'll build the reasoning systems, learning methods, retrieval algorithms, and evaluation infrastructure that allow every component of Doctronic's clinical AI to improve with each iteration and earn greater autonomy over time. This role blends research and engineering. What matters is real experimental or modeling work you can also ship, whether you come from applied ML or data science with strong engineering skills, or engineering with a research bent., * Design and implement the next generation of the architecture behind Doctronic's AI doctor, including reasoning, reflection, verification, tool use, routing, uncertainty handling, and escalation. * Build systems in which specialized agents and models work together to make clinical decisions safely, reliably, and efficiently, with an architecture that supports self-improvement over time. Evaluation and Measurement * Build the evaluation platform, rubrics, simulations, and experiments that measure how the AI doctor performs and know when a benchmark score rewards the wrong behavior. * Identify what should be improved, whether reasoning, retrieval, model behavior, data, or engineering, and determine whether each intervention genuinely made the system better. Models and Learning * Apply methods such as fine-tuning, distillation, reinforcement learning, preference optimization, and prompt and system optimization to improve specific components of the AI doctor. * Build the training data, feedback, reward, and experimentation pipelines that turn evaluation results and clinical expertise into system improvements. Search, Retrieval, and Grounding * Build search, ranking, retrieval, and grounding algorithms that connect clinical reasoning to trusted medical evidence, partner-specific content, and patient context. * Improve and evaluate retrieval based on its effect on downstream clinical decisions, not only on document-relevance metrics. Wherever you're working, you'll own the problem end-to-end, from framing it to measuring whether it worked. How We Work * Builder-first org: senior engineers who take ownership of a problem and run with it * Autonomy here means moving fast on your own judgment and bringing in clinical, product, or engineering partners early when the problem calls for it, not after. ## Related Videos - [Creating a routing app with Google Maps API from scratch](https://www.wearedevelopers.com/videos/831-creating-a-routing-app-with-google-maps-api-from-scratch) - [Modern Data Architectures need Software Engineering](https://www.wearedevelopers.com/videos/1030-modern-data-architectures-need-software-engineering) - [Fireside Chat: Deep Learning, Deep Impact: Harnessing AI for Language Innovation](https://www.wearedevelopers.com/videos/612-fireside-chat-deep-learning-deep-impact-harnessing-ai-for-language-innovation) - [AI in High-Stakes Industries: Lessons Learned](https://www.wearedevelopers.com/videos/100253-ai-in-high-stakes-industries-lessons-learned) - [AI & Ethics](https://www.wearedevelopers.com/videos/1455-ai-ethics) - [A Technical Introduction to Bitcoin's 2nd Layer- The Lightning Network](https://www.wearedevelopers.com/videos/15-a-technical-introduction-to-bitcoin-s-2nd-layer-the-lightning-network) ## Related Articles - [How to Become an AI Engineer](https://www.wearedevelopers.com/magazine/331-how-to-become-an-ai-engineer) - [MLOps And AI Driven Development](https://www.wearedevelopers.com/magazine/82-mlops-and-ai-driven-development) - [Navigating the AI Shift](https://www.wearedevelopers.com/magazine/629-navigating-the-ai-shift) - [How to start an AI project for a good cause and boost your career](https://www.wearedevelopers.com/magazine/15-how-to-start-an-ai-project-for-a-good-cause-and-boost-your-career) - [What Industries Outside of AI Are Hiring The Most AI Experts?](https://www.wearedevelopers.com/magazine/98-what-industries-outside-of-ai-are-hiring-the-most-ai-experts) - [Got AI ideas but no money?
