Kaia is a mission-focused health technology company.
Our story began in 2016, when our founders Konstantin Mehl and Manuel Thurner, set out on a mission to bring affordable and accessible relief to millions of people with chronic conditions. No strangers to chronic pain themselves, they decided to innovate ways to remove the obstacles many people experience in getting the leading-edge care they need in order to live their best lives.
How do Kaia apps work? Kaia uses a dynamic AI-powered algorithm. Our programs are based on multimodal rehabilitation, a holistic approach to managing chronic conditions. Our users have easy access via smartphone and tablet to our programs for back/hip/knee pain and COPD using this evidence-based approach.
Five years into our story, we are a leader in digital therapeutics, with 500,000+ users worldwide. Having raised $125 million from investors such as Optum Ventures, idInvest, and Balderton Capital. We are poised to create a global footprint in digital self-care; Kaia is patient empowerment made easy.
The regulatory landscape is quickly adapting to the digital ecosystem. Therefore, our mission and strategy bring new opportunities for exceptional talent to join our journey. With over 100 “Kaianeers” spread across the globe, we need now, more than ever, specialized talent to help take our mission further.

We are hiring a Senior or Staff-Level Full Stack Engineer with strong product focus and architecture skills. This is a key role with significant scope and growth potential. You will have support and visibility across our VP Engineering, VP Product, and other senior technical staff.

  • Optimize applications for speed, observability, simplicity


  • Proficiency with web technologies (we use Vue) and a backend stack (we use Rails)
  • Experience with relational databases like Postgres, data modeling, and data quality
  • Ability to articulate and balance architecture tradeoffs - as well as good intuition for how architecture choices might play out long-term
  • Accustomed to operating in a “you build it you run it” environment (incl. e.g. setting up an SDLC, managing deployments, and infrastructure)
  • Intrinsic desire to learn and fill in missing skills needed to achieve the desired outcome
  • Ability to move fast in an environment where things are sometimes loosely defined and may have competing priorities
  • Ability to articulate your thoughts clearly and succinctly, both in spoken and written form
