What we're looking for: We are seeking a technically hands-on Application Security Engineer to join the Information Security team. This individual will own the vulnerability management lifecycle across our SAST, DAST, and SCA tooling, integrate security automation into the CI/CD pipeline, perform threat modeling of product and engineering designs, and serve as a trusted advisor to our 300+ person engineering organization. The ideal candidate is a builder who would rather automate a finding than file a ticket, and who can explain a critical vulnerability to a junior developer without making them feel two inches tall. Arcadia is headquartered in Washington, DC, and open to fully remote candidates. #LI-REMOTE What you'll do: Own the end-to-end vulnerability management lifecycle: triage, prioritize, and drive remediation of findings from SAST, DAST, and SCA tooling in partnership with engineering squads. Maintain, optimize, and extend security tooling integrations within the CI/CD pipeline with the goal of automating everything that can be automated. Launch and run a Security Champions program, including workshops and office hours, to embed security knowledge directly into development teams across multiple geographies. Act as the application-layer subject matter expert during security incidents, supporting triage, root cause analysis, and remediation. Partner with Product and Engineering leadership to introduce security touchpoints earlier in the SDLC, including threat modeling and design review processes. What will help you succeed: Must-haves: 3–5 years of dedicated Application Security experience in a SaaS or cloud-native environment. Hands-on proficiency with at least two of the following: SAST, DAST, SCA, or CSPM tooling (e.g., Snyk, Checkmarx, Semgrep, Wiz). Strong working knowledge of CI/CD pipelines (e.g., GitHub Actions, Jenkins, GitLab CI) and the ability to write and maintain pipeline integrations. Experience with container security (Docker, Kubernetes) and API security patterns (REST, GraphQL). Demonstrated ability to communicate technical risk to non-security engineers in a way that drives action, not anxiety. Nice-to-haves: Experience standing up or maturing a Security Champions program. Familiarity with cloud-native AWS security services (GuardDuty, Security Hub, IAM Access Analyzer). Exposure to threat modeling frameworks (STRIDE, PASTA, or lightweight equivalents). Relevant certifications (OSCP, GWAPT, CSSLP) — valued but not required.
