Application Security Engineer
Hybrid (Onsite 3 days/ week) / NYC
Contract Role

Our client’s Cybersecurity Organization is seeking an Application Security Engineer.

This role will be an integral component of the application security program end-to-end, from discovery and inventory of business unit applications, through tooling implementation, through embedding security and AI-assisted controls into business unit DevOps pipelines.

This is as much a relationship and influence role as it is a technical role; success requires partnering effectively with the client’s subsidiaries. 

Responsibilities:

  • Application discovery and inventory across all business units, including ownership mapping, technology stack profiling, and risk tiering.
  • Standing up and operating the AppSec tooling stack — SAST, SCA, secrets scanning, and container/IaC scanning — integrated into business unit CI/CD pipelines.
  • Designing and implementing AI-assisted triage workflows on top of AppSec tooling so that finding volume does not overwhelm developers and false positives are filtered before reaching engineering teams.
  • Defining secure SDLC requirements, threat modeling practices, and security gates that business units adopt as part of their standard development process.
  • Partnering with business unit development leaders to build the relationships and shared playbooks needed to operationalize AppSec without becoming a blocker to delivery.
  • Contributing to AI security strategy — evaluating emerging tools (AI code review assistants, agentic security testing, automated security requirement generation) and recommending what to operationalize and what to defer.
  • Producing executive-ready metrics and reporting that connect AppSec activity to business risk reduction.

Required Qualifications:

  • 7+ years in application security, product security, or security engineering, with at least 3 years in environments with multiple independent business units, brands, or product lines.
  • Hands-on experience deploying and operating modern AppSec tooling (e.g., Semgrep, Snyk, Checkmarx, Veracode, Apiiro, Ox Security, GitHub Advanced Security).
  • Working code-level proficiency in at least three commonly-used languages (e.g., Python, JavaScript/TypeScript, Java, C#, Go) sufficient to read, review, and triage findings.
  • Strong scripting and automation skills in Python or equivalent; comfortable building integrations against REST APIs and operating in CI/CD environments (GitHub Actions, GitLab CI, Jenkins, Azure DevOps).
  • Demonstrated ability to influence engineering organizations without direct authority — negotiating standards, driving adoption, and partnering with development leaders.
  • Practical understanding of OWASP Top 10, threat modeling methodologies (STRIDE, PASTA, or equivalent), and modern attack patterns including supply chain risks.

Preferred Qualifications:

  • Experience integrating LLM-based tooling into security workflows (alert triage, finding summarization, remediation guidance generation).
  • Familiarity with one or more compliance frameworks relevant to the client’s environment (HITRUST, HIPAA, NIST AI RMF, SOC 2).
  • Prior experience working in a regulated or healthcare-adjacent environment.
  • Cloud security depth in at least one major provider (AWS, Azure, GCP).
  • Public contribution to the AppSec community — OSS, conference talks, published research, or detection/rule contributions.
