The Application Security Architect leads secure design and architecture reviews, threat modeling, source-code reviews, and security initiatives across application, cloud, infrastructure, and identity layers. The role develops security architectures and documentation, mentors security and engineering teams, supports AI-assisted product security workflows, and advances security awareness through the Security Champions program. Responsibilities include communicating risks to technical and executive audiences and embedding secure practices throughout software development and deployment.

Leads architecture and development of scalable, high-availability software systems supporting millions of endpoints. Owns complex multi-team initiatives, makes technical decisions, mentors engineers, establishes engineering standards, and improves software quality. Requires deep Java development, distributed systems, API design, database engineering, system scalability, testing, and AI-assisted development experience.

Develop cross-platform C++ and Qt software for network device discovery, monitoring, and data collection across Windows and Linux. Build high-performance, concurrent, asynchronous systems that communicate with thousands of devices using SNMP, SSH, ICMP, WMI, and related protocols. Own testing, troubleshoot issues across application, operating-system, and network layers, optimize reliability and performance, and collaborate with backend, UI, QA, and product teams.

Own the reliability, performance, architecture, and lifecycle of heterogeneous database platforms. Design and operate relational, NoSQL, caching, time-series, and warehouse systems; improve provisioning, developer tooling, CI/CD, backups, disaster recovery, security, and performance. Influence architecture and product decisions, lead migrations and upgrades, troubleshoot developer and production environments, and establish platform standards, documentation, and regulatory traceability.

Perform penetration testing across applications, APIs, cloud environments, infrastructure, and client-side components. Identify, validate, score, and document vulnerabilities; support remediation and secure design with Engineering; triage bug bounty submissions; develop testing tools and scripts; and communicate findings to researchers, technical teams, and executives. The role also applies threat modeling, security frameworks, and emerging threat intelligence to improve organizational security.

Conduct proactive, hypothesis-driven threat hunts across endpoint, identity, cloud, and network telemetry. Use cyber threat intelligence and red-team findings to identify novel techniques, misconfigurations, and long-dwell intrusions. Map findings to MITRE ATT&CK, create detection packages, recommend configuration fixes, and partner with tooling, SOC, CTI, and red teams. Document reusable hunting methods and provide threat context during major incidents.

Own the vision, roadmap, prioritization, and delivery of endpoint management and security capabilities. Define features, workflows, requirements, and remediation experiences that help IT teams and MSPs identify and reduce endpoint risk. Collaborate with engineering, design, support, customers, and other product managers to understand market needs, deliver cohesive platform capabilities, and iterate using customer feedback and usage data.

Build backend-focused Java/Kotlin APIs and data-driven product features, while contributing to React dashboards and workflows. Design scalable systems, participate in architecture and code reviews, troubleshoot production issues using observability tools, and collaborate with data, reporting, design, and product teams to launch emerging products.

Lead development of scalable Java backend applications and high-availability cloud services. Design architectures, REST APIs, databases, caching systems, and distributed session infrastructure. Mentor engineers, drive technical initiatives, address performance and scalability challenges, and uphold quality and automation practices for endpoint management products.

Develop scalable C++ software that defines and enforces endpoint behavior across millions of managed Windows endpoints. Responsibilities include implementing features, improving platform performance, shipping production code, designing new systems, writing architecture documents, defining subsystem contracts, and collaborating with server, UI, product, and design teams. The role requires deep Windows systems and kernel-driver expertise, with preferred experience in WHQL, minifilter or WFP drivers, macOS Endpoint Security, and Linux kernel development.
