Why Medāna?

At Medāna, we're on a mission: to revolutionize health through intelligent, precise, human-centered innovations. We are moving beyond binary disease classifications into risk-based medicine, where prevention, prediction, and dynamic patient trajectories replace outdated thresholds. We’re not just building ML models - we’re rewriting the future of medicine with LLM-driven knowledge systems that make clinical decision-making risk based and conversational.

Your Impact

• Be the code-first engineer: develop, train, and evaluate algorithms yourself - not just oversee or guide others.
• Build and iterate risk-based predictive models that understand patient journeys, rather than one-off events.
• Push the boundaries of large language models (LLMs) to transform messy clinical data into structured insights.
• Work alongside clinicians, data scientists, engineers and product designers in a truly multidisciplinary team.
• Operate with agility, adapting your thinking, tools, and approaches as insights evolve.
• Bring 100% grit, resilience, and focus to every sprint.
• Know when “good enough” isn’t, and raise your bar to excellent - Every. Single. Time.

What We're Looking For

• Hands-on in ML: You’ve built, refined, and shipped real models - from prototyping to production.
• Track record in applied AI: Experience with predictive modeling, healthcare data, or risk scoring systems is a big plus.
• LLM curiosity & skills: Familiarity with fine-tuning or applying LLMs to domain-specific problems (medical - huge plus).
• Can-do, startup mindset: resourceful, resilient, and ready to roll up your sleeves in ambiguous, fast-paced contexts.
• Proven delivery track record: multiple projects where you've pushed through complexity to results.
• Purpose-driven: passionate about using ML and LLMs to make healthcare more precise, humane, and accessible.
• Agile thinker: pivot quickly when insights shift - no ego, just solutions.
• Collaborative by nature: thrive in cross-functioning spaces - R&D, clinical, design, product, you name it.
• Flexible and adaptable: startup life changes at the drop of a hat - you're ready for whatever comes next.

What We Offer

• Be a cornerstone of Medāna’s early R&D engine - your work directly shapes our future.
• A deeply purpose-driven culture, where “why” matters (at least) as much as “what” or “how.”
• The chance to pioneer risk-based medicine models and LLM-driven health intelligence at scale.
• A supportive team that runs on trust, passion, and relentless curiosity.
• Meaningful healthcare impact. Join us to save lives.
