What You’ll Do 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. The Day to Day Security Discovery and Threat Modeling: 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. Architecture & Secure Product Development: 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. Application Security Testing Framework: 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. Vulnerability Management & Remediation: 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. Compliance & Audit Readiness: Ensure all security requirements, threat models, testing evidence, and remediation documentation align with internal compliance needs (e.g., HITRUST, SOC 2). Minimum Qualifications Bachelor’s degree in Computer Science, Information Security, or a related field. 3+ years (Engineer) to 5+ years (Senior) of experience in information security, with a strong focus on Application Security, DevSecOps, or software engineering. Demonstrable experience integrating security tools into CI/CD pipelines (e.g., SAST, DAST, SCA). Experience leading or performing application threat modeling, architecture reviews, and manual security testing. Familiarity with securing cloud environments (SaaS, IaaS, PaaS) and understanding of cloud architecture. Internet Connectivity
