Technical Lead, Product Security (DevSecOps)

Arista Networks•Austin, TX

About The Position

Arista Networks is seeking a deeply technical and operationally strategic Technical Lead, Product Security Program & Operations. In this role, you will serve as a core link between Arista’s engineering groups, external security researchers, federal stakeholders, and executive leadership. This is not a purely administrative role; it requires a strong technical background in network operating systems, exploit mechanics, and secure software development. You will drive the product security vulnerability lifecycle, lead threat modeling and penetration testing strategies for Arista’s switch architecture, integrate security mechanisms into our software development lifecycle (SDLC), and ensure our federal cloud environments maintain an aggressive security posture.

Requirements

Deep understanding of software vulnerabilities, exploit mechanics (e.g., buffer overflows, race conditions, logical bypasses, dependency vulnerabilities), cryptography, and modern mitigation techniques.
Strong familiarity with standard frameworks including CVSS, CWE, OWASP Top 10, and MITRE ATT&CK.
In-depth understanding of network switch architecture, composition, and management.
Knowledge of network operating system internals (ideally Linux-based, such as Arista EOS), control plane protection, data plane forwarding, ASIC-level considerations, and protocols (e.g., BGP, OSPF, gRPC, SNMP).
Robust knowledge of modern software engineering methodologies, version control (Git), and CI/CD pipelines.
Hands-on experience integrating and managing AppSec tools (SAST/DAST) and implementing Threat Modeling practices in an enterprise environment.
7+ years of experience in Product Security, Software Security Engineering, PSIRT operations, or Advanced Cloud Security Administration.
Proven experience hardening enterprise/federal cloud spaces, specifically Google Workspace or major cloud providers (AWS/GCP), with an emphasis on access controls, logging, and audit logs.
Familiarity with Federal, State, and Local compliance regulations (e.g., FedRAMP, NIST, FIPS).
Exceptional ability to articulate highly technical security flaws and architectural concepts clearly to software developers, enterprise customers, and non-technical business executives alike.

Responsibilities

Drive the end-to-end process of turning discovered or reported vulnerabilities within Arista products into verified, highly accurate security advisories.
Triage incoming vulnerability reports from internal testing, automated tools, and external researchers. Evaluate exploitability, proof-of-concepts (PoCs), and determine blast radius/severity using CVSS and CWE frameworks.
Partner directly with software engineers to explain root-cause vulnerabilities, provide remediation guidance, and oversee the drafting and structural validation of technical security advisories.
Coordinate with the National Vulnerability Database (NVD), MITRE, and external research teams to ensure professional, precise, and timely disclosure.
Analyze vulnerability trends to identify systemic security gaps, delivering data-driven architecture recommendations to senior engineering leadership.
Manage the comprehensive execution of third-party security testing and red-teaming across Arista’s product portfolio.
Translate Arista’s switch architecture, control/data plane separation, and Sysdb-driven state mechanisms into clear threat vectors to scope high-value targets for penetration testers.
Critically review penetration testing findings, distinguish theoretical risks from practical exploits, and validate that engineering fixes comprehensively eliminate the underlying architectural susceptibility to security issues.
Distill complex cryptographic, hardware, or software vulnerabilities into clear risk profiles for executive management and enterprise customers.
Architect, implement, and optimize security checkpoints throughout Arista’s development lifecycles to detect flaws before code reaches production.
Drive the adoption and tuning of automated security tooling (SAST, DAST, SCA, and container scanning) directly into the CI/CD infrastructure.
Define and evangelize secure coding practices, threat modeling principles (e.g., STRIDE), and framework-level mitigations to mitigate common software flaws (memory unsafety, injection, privilege escalation).
Audit existing development workflows to eliminate friction between engineering velocity and product security compliance.
Securely administer and monitor the dedicated Google Workspace environment for Arista Federal.
Configure and audit cloud infrastructure settings in strict accordance with industry frameworks and federal regulations (e.g., FedRAMP, NIST 800-53).
Actively monitor logging, alerting systems, and audit trails to identify, investigate, and remediate suspicious activity or misconfigurations.
Lead security risk assessments for all proposed system alterations in coordination with Arista IT Security and Federal Management.
Act as the primary technical subject matter expert (SME) during deep-dive security discussions with enterprise and federal customers.
Authoritatively address complex customer compliance inquiries regarding product architecture, supply chain integrity, and federal security mandates.
