About the role

Software Engineer role at AIOS (hybrid, Kosovo-based) developing full-stack AI-driven healthcare products. Role involves building end-to-end products, ownership of user experience, production ownership, and applying AI tools to accelerate development within a fast-growing, mission-driven startup.

Responsibilities

  • Build Products End to End: You’ll work closely with product and design to understand the problem, shape the solution, build it across the stack, and carry it through production.
  • Own the Experience: You’ll care about the complete experience, including edge cases, loading states, performance, reliability, and the small details that determine whether a product feels excellent.
  • Build to Last: You’ll write clear, tested, observable, and maintainable software. You’ll choose simple architectures, handle failure cases properly, and strengthen the foundations beneath your work.
  • Own Production: You’ll instrument what you ship, follow the relevant metrics, investigate failures, and keep iterating until the product creates the intended outcome.
  • Use AI as a Force Multiplier: You’ll use Claude Code, Codex, and other AI tools throughout development to move faster, explore more ambitious solutions, and increase the quality of your work.
  • Raise the Engineering Bar: You’ll review code seriously, communicate decisions clearly, share context, improve weak systems, and help the engineers around you do better work.

Qualifications

  • Experience: 3+ years of professional software engineering experience and have shipped meaningful products used by real customers.
  • Full-Stack Engineering: You can deliver across frontend and backend systems. You may be significantly stronger on one side, but you are comfortable working across both.
  • Product Mindset: You care about what should be built, how it feels to use, and whether it creates the intended outcome.
  • Engineering Quality: You write clear, tested, observable, and maintainable software. You understand architecture, databases, APIs, failure modes, and production reliability.
  • Ownership: You acquire context proactively, raise uncertainty early, follow your work into production, and take responsibility for reaching the outcome.
  • Judgment: You can balance speed, simplicity, and long-term maintainability. You push back clearly when a technical or product decision does not make sense.
  • AI-Native Execution: You use AI development tools effectively and remain fully accountable for the quality and correctness of the work they help you produce.

About AIOS

Building AI-native infrastructure for the next era of care.

Our overarching mission is to build the AI operating system for consumer healthcare - delivering end-to-end care with near-zero marginal human time. We believe the future of healthcare is automated, intelligent, radically lower cost, and built around the consumer. We believe biology is entering a golden age. We believe profitable, focused companies beat bloated ones. We're determined to get the humans out of healthcare - replacing slow, expensive, legacy workflows with software-driven care delivered at scale. We’ve started by building this infrastructure to power our own brands - including Bolt Pharmacy and Fella Health, among others. Today, that infrastructure is helping patients access life-changing treatment for excess bodyweight. Over time, we’ll extend it across many of the categories that will define the next era of healthcare. Our infrastructure will have served 100 million patients worldwide by 2035. We’ll then use that infrastructure to deliver next-generation healthcare products at massive scale. In doing so, we aim to build the world’s first trillion-dollar healthcare company.
