Note: The job is a remote job and is open to candidates in USA. OpenLoop provides telehealth support solutions that help companies deliver virtual care to patients across all 50 states. The Sr. Staff Security Engineer will serve as the most senior technical authority for security architecture, owning architecture standards, leading threat modeling and reviews, and translating healthcare regulatory requirements into secure architectural controls. The role also partners with engineering and executive leadership, establishes zero trust and cloud security practices, and mentors the security team.
Responsibilities
- Own and continuously evolve OpenLoop's security architecture across cloud infrastructure, applications, and corporate systems — defining standards, patterns, and reference architectures that teams build to
- Lead threat modeling across product, engineering, and infrastructure initiatives, with particular attention to PHI data flows, patient-facing interfaces, and virtual care delivery systems — and coach engineers to threat model their own work
- Conduct architecture reviews for new and existing systems, evaluating designs against security principles and regulatory requirements and producing actionable recommendations
- Design and continuously improve the architecture review process itself so that it scales with engineering velocity — including self-service patterns, risk-tiered review paths, and clear criteria for when full review is required
- Partner with the CTO and enterprise architecture function, embedding security review within existing technical governance rather than running a parallel process
- Define and champion application security standards, including secure design principles, API security, authentication and authorization patterns (OAuth/OIDC, SAML), and data protection controls — including healthcare interoperability standards such as HL7 and FHIR
- Establish and maintain a zero trust architecture strategy across identity, network, endpoint, and data layers
- Architect and govern key management, secrets management, and certificate lifecycle practices across cloud-native environments
- Own the security architecture for third-party integrations, defining how external systems connect to OpenLoop's environment and ensuring supply chain risk is controlled at the design stage
- Serve as the primary security partner for product and engineering leaders, embedded in design and planning cycles to shape secure-by-default systems
- Maintain security architecture documentation, including architecture decision records (ADRs), reference designs, and control frameworks
- Take security and compliance requirements from GRC, Privacy, and audit partners and translate them into concrete architectural controls — with particular depth in the HIPAA Security Rule's technical safeguards as they apply to PHI architecture
- Partner with the CISO and security leadership on the long-term architecture roadmap, producing clear metrics and executive-ready reporting on architecture risk posture
- Mentor and elevate the broader security team, raising architectural thinking and design quality across all security domains
- Research emerging threats and attack techniques — including threat actors actively targeting healthcare — to keep OpenLoop ahead of the threat landscape
- Other duties as assigned
Skills
- Bachelor's degree in Computer Science, Information Security, or a related field, or equivalent professional experience
- 10+ years of progressive security experience, with at least 5 years focused specifically on security architecture across enterprise and cloud environments
- Deep expertise across multiple security domains: application security, cloud security, identity and access management, network security, and data protection
- Hands-on experience architecting security solutions in cloud environments, including network security design, IAM, key and secrets management, encryption, and cloud-native security services
- Proven experience leading threat modeling using structured methodologies (STRIDE, PASTA, or equivalent) at varying scales — from individual features to whole systems — including evaluating others' threat models and training engineers to produce their own
- Strong command of secure software development lifecycle (SSDLC), OWASP principles, and application security design patterns
- Proficiency in modern authentication and authorization patterns (OAuth 2.0, OIDC, SAML), including across multi-tenant and patient-facing applications
- Experience architecting key management, secrets management, and PKI/certificate lifecycle controls in cloud-native environments
- Working knowledge of HIPAA (including Security Rule technical safeguards), HITRUST CSF, NIST CSF, and SOC 2, sufficient to design controls that satisfy them
- Demonstrated ability to communicate complex architectural risk to both technical and executive audiences
- Experience in healthcare, digital health, or another highly regulated industry
- Experience designing and evaluating zero trust architectures in production
- Experience designing or scaling an architecture review process — including risk-tiering, self-service patterns, or integration with an existing technical review board
- Familiarity with API security architecture and healthcare data exchange standards (HL7, FHIR)
- Familiarity with security architecture frameworks such as SABSA or TOGAF security extensions
- Experience mentoring senior engineers or establishing architecture practices from scratch
