Requisition #: 2001

Job Title: Security Engineer

Location: Remote

Clearance Level: Ability to Obtain and Maintain a Public Trust Clearance

Job Description

SUMMARY We are seeking a highly motivated and skilled Security Engineer to support and enhance our cybersecurity operations. The ideal candidate will be responsible for designing, implementing, and maintaining security solutions that protect enterprise systems, applications, networks, and data. This role requires a strong technical background, a proactive approach to problem-solving, and a commitment to supporting mission and customer objectives.

JOB DUTIES AND RESPONSIBILITIES

A Security Engineer is responsible for designing, implementing, maintaining, and improving security solutions that protect an organization's systems, networks, applications, and data from cyber threats.
This role involves monitoring security tools and alerts, conducting vulnerability assessments, supporting incident response and remediation efforts, implementing security controls, and ensuring compliance with organizational and regulatory requirements.
Security Engineers collaborate closely with SOC analysts, system administrators, developers, and stakeholders to identify risks, strengthen security posture, and support mission objectives.
They also develop security documentation, support audits and assessments, analyze emerging threats, recommend process improvements, and stay current on evolving cybersecurity trends and technologies to enhance operational effectiveness and reduce organizational risk

Education and Years of Experience

Bachelors Degree, 7 years of experience

Required Skills

Engineering, deploying, and sustaining the enterprise network security infrastructure-next-generation firewalls, SASE/ZTNA, and SD-WAN-to ensure availability, performance, and a defensible security posture.
Operating and maintaining defensive platforms day-to-day, including configuration management, policy tuning, software/firmware lifecycle and patching, capacity planning, and health monitoring.
Leading engineering projects end-to-end-requirements, design, testing, and implementation-for new and upgraded capabilities such as SASE/ZTNA and SD-WAN across enterprise and hybrid (on-premises and cloud) environments.
Developing and maintaining secure configuration baselines, standard operating procedures, and engineering documentation, and automating repeatable configuration and operational tasks to improve consistency and reduce manual effort.
Translating threat intelligence and detection findings into infrastructure-level defensive improvements-firewall policy, segmentation, access control, and traffic inspection-to harden the environment against current adversary tactics.
Collaborating with the SOC, logging and observability, and network operations teams, and with product vendors, to integrate capabilities, resolve issues, and align infrastructure with operational and mission requirements.
Operating and supporting intrusion detection sensor infrastructure to ensure reliable security telemetry delivery to the SOC and logging/observability teams.
Identifying gaps in defensive coverage, resilience, and operational processes; recommending and implementing improvements; and providing technical input to architecture and roadmap decisions.
