Principal AI Engineer

We anticipate the application window for this opening will close on - 15 Sep 2026. At Mini Med, you can begin a lifelong career of exploration and innovation, while helping make a difference in the lives of people living with diabetes around the globe. You'll lead with purpose, breaking down barriers to innovation for a more connected, compassionate world.

Mini Med is building a lean, high-leverage AI & Data Science team. We are looking for a Principal AI Engineer to be our senior technical anchor — the person who builds AI capabilities hands‑on and sets the standard the rest of the team builds to. This is a builder’s role first. You will take AI/ML models and LLM-powered agents from a fast “proof of life” prototype through to a production deployment that holds up in a regulated environment.

Roughly a fifth of your time goes to the force‑multiplier work: reviewing and quality‑gating other engineers’ designs, and establishing the reusable patterns that keep the architecture and the hard‑won judgment in‑house. To be clear about what this is not: this is not a people‑management role, and it is not a role where you hand a notebook to someone else to product ionize.

You own the capability until it is live and delivering value.

• Prototype fast. Demonstrate “proof of life” for AI/ML models, agents, and tools against real Mini Med business problems, working from the business’s actual data and workflows rather than a sanitized sandbox.
• Take it to production and drive adoption. Build, evaluate, and deploy on the MIA stack (Databricks, Lang Graph/Lang Smith, enterprise agent platforms), applying evaluation‑driven development, guardrails, and deployment patterns so what ships is reliable, auditable, and maintainable. You own the capability from prototype through initial production release and its first monitoring cycle — measured by real adoption and business value, not just a stable deployment — then hand off to Model Operations for steady‑state run.
• Integrate into the enterprise environment. Wire agents and models into the surrounding systems — APIs, identity and access (SSO/SAML/OAuth), systems of record such as Salesforce and SAP, and enterprise data pipelines — so capabilities work against real, messy production systems rather than in isolation.
• Set the technical standard. Establish reusable patterns for agent design, tool‑calling, retrieval, and evaluation harnesses; review and quality‑gate the work of other engineers on the team so the bar holds without a manager in the loop.
• Feed learnings back to the platform. Turn what you learn in the field into improvements to the MIA platform, shared tooling, and reusable‑pattern roadmap, so each deployment makes the next one faster.
• Self‑direct against outcomes. Partner with the Product Manager, AI & Data Science to choose what to build and when to stop, without needing the problem pre‑decomposed for you.
• Build for a regulated environment. Uphold the safety, privacy, and compliance requirements of a medical‑device context, including auditability and human‑in‑the‑loop where required.

Minimum Requirements

• Bachelor’s degree in Computer Science, Engineering, or a related technical field and 8+ years of of relevant experience or advanced degree with a minimum of 6+ years of relevant experience.

• Demonstrated delivery of LLM-powered systems or ML models to production — not prototypes, evaluations, or internal demos alone.
• Strong system design skills and end-to-end ownership from prototype through production deployment.
• Experience technically leading or directing other engineers, including reviewing their work.
• Strong stakeholder-facing communication — able to scope ambiguous problems with business partners and explain…
