Senior Application Security Engineer

**Senior Security Engineer** **Reports To:** Sr. Director of IT & Security **Locations hiring from:** Alabama,Arizona, Arkansas, California, Colorado, Delaware, Florida, Georgia, Idaho, Illinois, Indiana, Kansas, Louisiana, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, Nevada, New Hampshire, New Jersey, New York, North Carolina, Ohio, Oregon, Pennsylvania, Rhode Island, South Carolina, Tennessee, Texas, Utah, Vermont, Virginia, and Wisconsin. **Employment Type:** Full-time **Role Overview:** As Oshi Health's first dedicated Senior Security Engineer, you will own the technical security of our fully remote, SaaSand cloud-native healthcare platform, protecting the sensitive health data of real people working to take back control from chronic GI conditions. This is a hands-on, builder-focused role, not a policy desk: you will set security architecture standards, harden identity and secrets management, and build security into our engineering and AI workflows from the start. It is a uniquely forward-looking opportunity to shape how a growing healthcare platform stays safe as it adopts agentic AI development, with your fingerprints on the foundation. **What You'll Do — Key Responsibilities** - Own application and product security, including threat modeling, secure design review, and secure code review, with a focus on the access-control and secrets-exposure flaws that matter most for a member-facing healthcare app and its APIs. - Design and own the security architecture for Oshi's shift to an agentic software development lifecycle, including phase-gate criteria, out-of-band controls so AI-written code is never its own security gate, and tested clawback procedures for when risk spikes. - Build and run non-human identity and secrets management at scale, covering service accounts, scoped tokens, OAuth grants, and machine credentials across our SaaS and AWS estate. - Secure our AWS environment end to end, including IAM, network segmentation, logging, encryption, and workload protection across S3, EKS, and Terraform. - Enforce and tune our security tooling so it does real work, including GitHub Advanced Security (CodeQL, secret scanning, push protection), branch protection, and CODEOWNERS-enforced review on sensitive paths. - Review AI and third-party vendor integrations before they touch PHI, evaluating data flows, retention, and data loss-prevention needs with healthy skepticism toward vendor security claims. - Own vulnerability management and the penetration-testing relationship, driving findings to closure and feeding recurring issues back into the development process. - Support HIPAA Security Rule technical safeguards, stand up detection and response capabilities, and build the automation that lets a small security function operate with outsized leverage. **What We're Looking For — Qualifications & Requirements** Required - Bachelor's degree in Computer Science or equivalent practical experience. - 6+ years in security engineering, with demonstrated depth in application/product security and cloud security (AWS). Experience in healthcare, fintech, or another regulated, data-sensitive environment is a strong plus. - Hands-on with secure SDLC tooling: SAST/DAST, GitHub Advanced Security/CodeQL, secret scanning, and software supply-chain/dependency security. - Strong in identity and access management, including Okta, OAuth/OIDC, SAML, phishing-resistant MFA, and the management of non-human identities and secrets. - Familiarity with, or a genuine drive to go deep on, securing AI/LLM and agentic systems: prompt injection, agent authorization and over-permissioning, NHI sprawl, and model/supply-chain risk. - Comfortable being the sole security specialist on a small, cross-functional team, prioritizing ruthlessly by risk and able to explain a tradeoff clearly to both engineers and non-technical executives. - Working knowledge of the HIPAA Security Rule, SOC 2, and the NIST Cybersecurity Framework. - Proficient with scripting and automation (Python and at least one shell). Preferred - One or more certifications: OSCP, GIAC (e.g., GWAPT, GCSA, GCLD), AWS Certified Security – Specialty, CISSP, or Okta Certified Professional. - Experience operating a compliance-automation platform. **Compensation & Benefits** - Salary Range: $170,000 – $190,000 + bonus and meaningful equity - Health Benefits: 90% employee premiums paid for medical, dental, and vision coverage - Time Off: Flexible PTO plus 11 Holidays and 1 floating holiday - Retirement: Eligibility to contribute to 401(k) - Work Style: Remote-first flexibility, work from home anywhere within our approved states in the US Compensation Range $170,000—$190,000 USD Note: This job description serves as a general overview and may be subject to change based on organizational needs and requirements.
