Application Security Engineer

• The Application Security Engineer is responsible for embedding application security directly into Strive’s product development lifecycle, specifically supporting the deployment of Canvas Medical, patient-facing experiences, and future mobile applications
• You will serve as the primary security partner for Product and Engineering, ensuring that applications are built securely from the design phase through to production. Rather than treating security as a late-stage penetration test, you will establish the requirements, review gates, testing frameworks, and remediation operating rhythms necessary to support a secure and compliant development pipeline
• Perform threat modeling and establish a security baseline for internal environments, patient portals, mobile applications, and integration services
• Maintain data-flow and trust-boundary diagrams, assessing identity, operational, and PHI data classifications
• Collaborate with engineering teams to embed security acceptance criteria into PRDs, technical plans, and Jira stories
• Conduct architecture reviews focusing on tenant boundaries, server-side authorization, prevention of IDOR (insecure direct object references), and lateral movement guardrails
• Develop and enforce merge request (MR) checklists covering authentication, input validation, secrets management, and cryptography
• Design, deploy, and operate application security testing tools including SAST, DAST, Software Composition Analysis (SCA), and container/IaC scanning
• Perform authenticated testing of browser workflows and APIs (e.g., using Burp Suite Enterprise)
• Conduct manual testing for complex vulnerabilities such as privilege escalation, SSRF, and business-logic abuse
• Manage the vulnerability intake pipeline, assign severities, and track remediation aligned with internal SLAs
• Lead recurring vulnerability review sessions with Security, Product, and Engineering stakeholders
• Coordinate external penetration tests, including scoping, vendor selection, and tracking of remediation/retesting
• Ensure all security requirements, threat models, testing evidence, and remediation documentation align with internal compliance needs (e.g., HITRUST, SOC 2)
