About The Position

At Wellthy, we dream of a world where everyone has the care infrastructure they need to manage their own health and the health and well-being of their loved ones.

We’re building something new in the care space - reimagining how care is delivered, accessed, and supported by families around the globe. As we grow, we’re seeking collaborative, curious, and purpose-driven teammates to help us expand what’s possible.

Our work is grounded in the expertise of seasoned care professionals who deeply understand families’ real challenges paired with agile, tech-powered solutions that deliver support efficiently and at scale. We embrace a mindset of continuous learning, especially around emerging technologies. Tools like AI and other innovations are accelerators, enabling us to scale our impact, work smarter, and stay at the forefront of care delivery.
Through Wellthy, millions of families have access to support to help them manage care during every stage of life, with hands-on experts guiding families through caregiving or backup care journeys. And with the acquisition of Patch Caregiving, Wellthy continues to expand how care shows up for working families by pairing care navigation and coordination with on-site and near-site employer-based childcare. This combination allows us to support families not just in navigating care decisions, but in accessing real, hands-on help when and where they need it most. Together, we’re building a more connected, comprehensive care experience for families and caregivers alike.
We partner with leading companies including more than 40 Fortune 500 companies to support the care needs of their workforces globally. We also work alongside health plans and carriers to embed care support into their offerings, enhancing the experience and outcomes for members.

We’re building, evolving, and expanding the market category for care, and we’re looking for responsive, collaborative, curious, and purposeful colleagues to join us.
As our Senior Applied AI Engineer, you will partner closely with the CTO to design, develop, and implement applied AI solutions (retrieval-augmented generation, LLM orchestration, and safe agentic workflows) and drive the AI-first transformation of our product and engineering teams.
You will report directly to the Chief Technology Officer.
