About BIOS Life
BIOS Life is a Boston-based, venture-backed healthcare technology company on a mission to fundamentally change how cancer is detected, monitored, and managed. We’re building a new model of proactive, personalized cancer care that combines advanced AI, real-world clinical data, and evidence-based medicine to help patients and clinicians make better decisions throughout the cancer journey.
Our platform brings together longitudinal patient data, predictive risk models, clinical decision support, and virtual care delivery to enable more personalized cancer screening, surveillance, and survivorship care. We’re building both the technology and clinical infrastructure to make this approach scalable, accessible, and integrated into patients’ lives.
We’re an early-stage company with an ambitious mission and a collaborative, multidisciplinary team spanning engineering, AI, clinical care, and operations. We’re looking for people who are excited to build something meaningful, solve complex problems, and help shape the future of cancer care.
The Role
We’re looking for a hands-on Staff Security & Platform Engineer to own and evolve the cloud infrastructure, platform engineering, and technical security foundations that support BIOS.
You’ll be the primary technical owner of our AWS and GCP environments, working across cloud architecture, infrastructure automation, DevSecOps, observability, reliability, and security operations. You’ll also serve as the technical counterpart to our managed IT, SOC 2 compliance, and Quality/Regulatory partners.
As an early-stage company, we’re looking for someone who thrives in a dynamic, collaborative environment, enjoys solving problems across disciplines, and is comfortable adapting as the company grows. You’ll work closely with Product Engineering, AI, and other teams to build secure, scalable infrastructure supporting our clinical applications, data platforms, and AI capabilities.
This is a highly collaborative, hybrid role based in our Cambridge office, with a minimum of three days per week onsite . We value working together in person to solve problems, share knowledge, and build strong relationships across our Engineering and AI teams. You’ll have the opportunity to shape our technical foundations, influence how we work, and contribute directly to BIOS’s mission and engineering culture as we scale.
Our goal isn’t to create an infrastructure gatekeeper. It’s to build secure, reliable, self-service infrastructure—through automation, reusable patterns, and sensible guardrails—that enables engineering teams to move quickly without compromising security or operational discipline.

Partner with Engineering teams to improve operational readiness and resilience as the platform scales.
Security Operations & Vulnerability Management
Maintain cloud and infrastructure security posture, proactively identifying configuration risks, vulnerabilities, and security gaps and driving remediation.
Own technical vulnerability management and coordinate penetration testing, security assessments, and remediation tracking in partnership with Engineering and external specialists.
Lead infrastructure and cloud-security incident preparedness and response, including investigation, containment, recovery, and post-incident improvements.
Partner with Engineering and AI teams on threat modeling and security architecture for new platform capabilities, including mobile, web, and AI applications.
Compliance Engineering & Audit Readiness
Implement and maintain technical security and infrastructure controls supporting SOC 2 and other applicable regulatory and compliance requirements.
Maintain integrations with Vanta and other assurance tools, automating technical evidence collection wherever practical.
