Security Engineer

Building Healthcare That Remembers Every time you call a doctor's office, the system forgets you the moment you hang up. You wait on hold, explain everything from scratch, get bounced between lines, and hope someone follows up. Everyone has felt this. No one should have to. At Assort Health, we're building one continuous conversation for every patient. An AI agent that knows who you are, remembers how you like to be reached, and carries that context from your first symptom to your full recovery. What began as the first voice AI agent to schedule a specialty appointment has become the largest proprietary specialty dataset in healthcare: 190 million patient interactions, 62,000 care protocols, 1.6 million decision pathways. We went from 15 people in 2025 and will cross 250 by the end of 2026. Revenue is up 20x in 15 months and we've raised $222 million, including a recent $120 million Series C https://www.assorthealth.com/blog/assort-health-raises-120-million-series-c-to-scale-largest-deployment-of-ai-agents-for-the-patient-journey at a $1.2 billion valuation. We've also been named to the Forbes Cloud 100 and the 2026 Enterprise Tech 30 as the only healthcare AI company on the list! Healthcare spends $1.1 trillion a year on administration instead of care.

About the role We are looking for a Security Engineer to help build and strengthen security foundations from the ground up in a fast-moving startup environment. This is a strong opportunity for someone early in their career who brings a generalist security mindset and is excited to work across product security, infrastructure security, detection and response, and enterprise security. The role is designed for someone who wants meaningful ownership, broad exposure, and the chance to help shape how security operates as the company matures. You will partner closely with teams across the organization, help close foundational gaps, and contribute to building a more robust, continuous security program over time. This role is based in San Francisco and follows a 4-day in-office working model. What you'll be doing - Help build the company’s foundational security program across multiple domains, with a focus on practical improvements that strengthen overall security maturity. - Work on cloud and infrastructure security initiatives, helping identify gaps, improve configurations, and support a secure environment in a primarily cloud-based setup. - Contribute to detection and response efforts by helping establish monitoring, incident response, and related operational security processes as internal capabilities are developed. - Support product security work, including reviewing code or infrastructure patterns, identifying security issues, and partnering with engineering on remediation. - Collaborate with internal stakeholders across the organization to implement security projects, improve coverage, and drive progress on high-priority initiatives. - Assist with security efforts related to SOC 2 and help translate immediate audit-driven needs into longer-term, sustainable security practices. - Evaluate and help implement security tooling, with the flexibility to explore a range of approaches, including modern platforms, open-source options, and AI-enabled tools where appropriate. - Take ownership of hands-on technical work, scripting, and automation tasks that help the team move quickly and reduce manual effort. What we're looking for - A security generalist profile with exposure to several areas of security rather than a narrow specialization. - Strong interest in infrastructure and cloud security, with the ability to understand technical environments and identify meaningful security improvements. - Comfort working in a fast-paced startup environment where priorities can shift and the workload can be intense. - A high degree of ownership, autonomy, and initiative, with the ability to make progress in environments that are still being built. - Will
