We are looking for an Application Security / Security Architect to help embed security across the application lifecycle. In this role, you will partner with R&D, DevOps/Cloud, product, and the cybersecurity team to improve the security of applications, APIs, repositories, data stores, and application-facing cloud services.
You will combine architecture, threat modeling, secure software development, vulnerability validation, and practical engineering partnership. You will review designs and high-risk changes, define security requirements and reusable patterns, validate findings from vulnerability-management and security-assessment tooling, penetration tests, and bug-bounty activity, and turn those findings into clear, prioritized remediation work for engineering teams.
This role is ideal for someone who can move comfortably between architecture discussions, code and configuration reviews, security testing, and executive-level risk communication. The goal is to help the company build secure applications by design while making application-security decisions faster, clearer, and more measurable.
Responsibilities
- Own and mature the application-security and security-architecture program across product and internal applications, APIs & services, and data stores.
- Conduct threat modeling, architecture reviews, security design reviews, and risk assessments for new systems and materially changed services.
- Define application-security requirements, review triggers, and practical security patterns for authentication, authorization, secrets, data protection, input handling, APIs, service-to-service communication, and security logging.
- Review source code, high-risk configurations, CI/CD security checks, and application integrations with engineering teams; provide actionable guidance to enhance security posture.
- Validate and prioritize findings from vulnerability-management and security-assessment tooling, penetration tests, and other security assessments - distinguish true risk from noise, and translate findings into clear engineering tasks and track their status.
- Own the operating process for penetration testing and bug bounty programs, including scope, intake, triage, communication, remediation tracking, and verification of fixes.
- Identify recurring vulnerability themes and root causes, then drive preventive improvements in engineering practices, tooling, architecture, and developer enablement.
- Partner with Security Operations to provide application context, logging requirements, detection opportunities, and context relevant to monitoring and incident response.
Requirements
- 4+ years of hands-on experience in application security, product security, security architecture, or a closely related role.
- Strong understanding of secure software development lifecycles, threat modeling, security requirements, architecture reviews, and practical risk assessment.
- Hands-on experience with web applications, APIs, microservices, authentication, authorization, data protection, secrets management, and service-to-service communication.
- Practical code-reading or code-review experience in one or more modern programming languages, with the ability to explain security issues clearly to engineers.
- Background as a software developer, or comparable hands-on experience as a builder — for example in DevOps engineering or software architecture — working with code on a daily basis.
- Experience with application-security tooling or equivalent capabilities, such as vulnerability management, SAST, DAST, SCA, secret scanning, CSPM, or security testing platforms.
- Experience validating vulnerabilities and managin g remediation from discovery through verified closure.
- Strong written and verbal communication skills, with the ability to influence R&D, DevOps, product, and business stakeholders without relying on authority alone.
- Experience using AI tools in day-to-day engineering work, as well as specifically for vulnerability analysis and exploitation, including AI-assisted code review, vulnerability triage, and exploit development.
Nice to have
- Experience building or maturing an application-security program in a cloud-native or fast-growing technology environment.
- Experience with security architecture for APIs, distributed systems, containerized or cloud-native workloads, data stores, CI/CD pipelines, and third-party integrations.
- Experience coordinating penetration testing, bug-bounty programs, responsible disclosure, and external security researchers.
