[Hiring] Application Security Engineer @Arcadia

Role Description

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.

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.

Qualifications

• 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.

Requirements

• 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.

Benefits

• "Remote first" culture - work anywhere in the US as long as you have a reliable internet connection.
• Flexible PTO - no accrued hours and no limit on the number of vacation days exempt employees can take each year.
• 12 annual holidays.
• 10 days sick leave.
• Up to 4 weeks bereavement leave.
• 2 volunteer days off.
• 2 professional development days off.
• 12 weeks paid parental leave for all parents.
• 75-95% employer cost coverage for medical, dental, and vision benefits for employees and dependents.
