Deliver application security and privacy training for development teams.
Review source code to identify security vulnerabilities, insecure patterns, secrets exposure, and risks associated with AI-generated code.
Triage, reproduce, and support remediation of application vulnerabilities (e.g., SQL injection, XSS, access control weaknesses) identified through automated tools (SAST, DAST, SCA) or manual analysis.
Manage application security workflows, including task prioritization, ticket tracking, and coordination with development and DevOps teams.
Maintain and enhance SmartRent’s responsible disclosure and vulnerability reporting program.
Partner with developers to implement encryption, hashing, and secure key management practices.
Collaborate with developers and engineering teams to perform threat modeling, identify attack paths, and assess weaknesses.
Lead the investigation and mitigation of application-level security incidents, collaborating with the SOC and engineering teams to ensure rapid remediation and stakeholder communication.
Provide guidance on security and privacy controls for cloud infrastructure (AWS), application development, and IoT hardware.
Conduct regular application risk assessments to identify vulnerabilities and emerging threats.
Research emerging cybersecurity risks and recommend mitigation strategies as appropriate.
Perform adversarial testing and security validation of applications, including internal AI models and services.
Use cloud-native security tools to identify and secure large language model (LLM) integrations and implement appropriate security guardrails.

Required Qualifications

4–6 years of experience in application security, including development and maintenance of security policies and collaboration with engineering and release teams.
Experience identifying and remediating application vulnerabilities across modern programming languages, including Elixir, JavaScript, Ruby, Python, or similar languages.
Strong knowledge of OWASP Top 10, OWASP API Top 10, and modern authentication mechanisms, including JWT and OAuth.
Hands‑on experience with application security tools, including SAST, DAST, and SCA platforms (e.g., GHAS, Burp Suite, Fortra, or similar tools).
Experience working with cloud security controls, including AWS‑native tools, web application firewalls (WAF), or similar technologies.
Experience managing or supporting vulnerability disclosure or bug bounty programs.
Strong written and verbal communication skills, with the ability to clearly communicate security requirements to technical teams.
Demonstrated problem‑solving and analytical skills in identifying and mitigating application security risks.

Preferred Qualifications

Industry certifications such as CSSLP, GIAC GWAPT, CEH, or equivalent security certifications.
Experience working with CloudFlare, AWS security services, or similar cloud‑native security tools.
