Systems Engineer III

Join a high-impact security engineering team focused on reducing risk and improving visibility across cloud, identity, network, and application environments. This remote Systems Engineer III role supports the rollout of an exposure management platform and helps turn complex security data into actionable remediation efforts.
Responsibilities

• Lead onboarding and configuration activities for a new exposure management platform.
• Coordinate integrations across cloud, identity, infrastructure, vulnerability, and other security data sources.
• Validate data ingestion, asset correlation, and exposure signal quality across environments.
• Partner with engineering, cloud, IAM, and application teams to support a smooth rollout and operational readiness.
• Help define workflows, reporting, and remediation processes aligned to continuous threat and exposure management cycles.
• Document integration steps, platform behavior, and operational procedures to support long-term program maturity.
• Identify and map internal and external attack surfaces across cloud, network, application, and SaaS environments.
• Detect unknown, shadow, misconfigured, or abandoned assets that increase exposure.
• Monitor changes in assets and maintain ongoing visibility into evolving environments.
• Prioritize remediation based on threat activity, exploitability, data sensitivity, criticality, and compensating controls.
• Support remediation planning, track progress, and confirm exposures are fully resolved.
• Contribute to program governance, metrics, reporting, and continuous improvement efforts.
• Work with IAM teams to assess privilege misuse, identity sprawl, and authentication weaknesses.

Skills

• Strong understanding of attack surface management, vulnerability management, cloud security, identity security, and network fundamentals.
• Hands-on experience with exposure, vulnerability, or attack surface tools such as ASM, CSPM, CIEM, VM scanners, EASM, or attack path analysis platforms.
• Knowledge of CTEM-aligned workflows or continuous risk reduction programs.
• Ability to interpret complex exposure data and translate it into clear, actionable insights.
• Understanding of threat modeling, attacker techniques, and current exploitation trends.
• Strong communication skills with the ability to engage both technical and non-technical stakeholders.
• Ability to coordinate across multiple teams and manage technical implementation details effectively.

Preferred Skills

• Experience supporting security program enablement, governance, or operational maturity initiatives.
• Familiarity with remediation tracking and reporting processes.
• Experience identifying and correlating assets across complex environments.
• Background working with cloud, infrastructure, application, or identity teams on security-related initiatives.
• Clear documentation skills and a process-oriented mindset.
