Senior Security Engineer

OUR MISSION Imagine building a better healthcare journey for patients with cancer, where individuals and their loved ones feel seen, supported, and heard by their care team – both in and out of the clinic. Where fast access to high-quality care is the norm, not the exception. Where patients have access to a care navigator to guide them through their diagnosis and trusted support all along the way. At Thyme Care, we share a passion for transforming the cancer care experience – not just for patients but also for their caregivers and loved ones, as well as those delivering and paying for their care. Today, Thyme Care is known predominantly as a cancer care navigation company enabling value-based cancer care; in the next few years, we will become a nationally recognized technology-driven and provider-centric care delivery model, reshaping the landscape of cancer care access, delivery, and experience. Our commitment runs deep—we're not satisfied with the status quo but determined to redefine it. To make this happen, we’re building a diverse team of problem solvers and critical thinkers to drive innovation and shape the future of healthcare. If you share our vision and want to be part of something truly meaningful, we want to hear from you. Together, we can revolutionize cancer care and make a difference that lasts a lifetime.
