Job Summary

The Application Security Engineer will be responsible for strengthening and continuously improving the security posture of the organization's applications. This role involves integrating security into the software development lifecycle (SDLC), embedding and automating application security testing within CI/CD pipelines, and driving timely remediation of identified vulnerabilities.

The engineer will work closely with application teams to perform security design reviews, triage and assess vulnerabilities, and guide teams on effective remediation, security best practices, secure coding and threat modeling.

Success for this role requires that you are

- Familiar with application security concepts, standards and trends (OWASP Top 10, OWASP ASVS, secure SDLC)
- Able to interpret and apply security principles and standards to application designs, architectures, configurations and policies
- Able to automate security controls using pipeline-as-code and infrastructure-as-code
- Driven to learn new things; excited about challenges and finding solutions
- A strong builder mentality with a drive to "see things through"
- Able to communicate technical concepts,



risk and remediation guidance clearly and concisely to developers, peers and management
- Able to demonstrate valuable judgment in prioritizing vulnerabilities based on their impact to the confidentiality, integrity and availability of information

Responsibilities

- Integrate, operate and continuously improve application security testing tools (SAST, SCA, Secret Scanning and DAST) within the SDLC
- Implement shift-left security practices to ensure vulnerabilities are detected and remediated early in the SDLC
- Conduct threat modeling, secure design reviews and architecture reviews with application teams to identify and mitigate risks early
- Triage, validate and prioritize findings from SAST, SCA, Secret Scanning and DAST; tune rules, policies and quality gates to reduce false positives
- Partner with application teams to remediate identified vulnerabilities by providing clear, actionable guidance and tracking findings through to closure
- Recommend and promote security best practices and secure coding standards, and educate developers on common vulnerability classes
- Build and maintain automation and scripts (e.g., Python, Terraform) to onboard applications to security tooling, enforce policy as code, and report on application security metrics
- Track and report on application security posture (e.g., vulnerability trends, remediation timelines, tool coverage)



to stakeholders and management

- Strong understanding of the OWASP Top 10, OWASP API Security Top 10, OWASP ASVS and related standards (NIST, CIS Benchmarks) and the ability to recommend solutions aligned with them
- Hands-on experience performing threat modeling (e.g., STRIDE, data flow diagrams) and secure design reviews
- Understanding of AI and LLM security risks and mitigations (e.g., OWASP Top 10 for LLM Applications, prompt injection, data leakage, model and AI supply chain risks) and how to secure AI-enabled applications
- Working knowledge of common vulnerability classes (e.g., injection, XSS, SSRF, broken access control, insecure deserialization) and how to remediate them in code
- Working knowledge of securing applications built on public cloud services (any of the major cloud providers)
- Ability to partner with application teams to remediate vulnerabilities and adopt secure coding practices
- Demonstrated ability to work within globally dispersed and cross-functional teams

Qualifications

- 4-5 years of work experience in Application Security or DevSecOps in a medium or large corporate environment; a bachelor's degree in computer science, engineering or a related field is preferred
- Demonstrated hands-on experience with each of the following:
- SCA (e.g., Apiiro, Nexus
