Our talented employee-owners provide agile, scalable services and solutions that solve operational gaps, operate critical systems, and protect and secure the enterprise – across the organization and around the world.
The Test Engineer will support mission-critical cyber sensing platforms that operate as part of a real-time network data and telemetry pipeline. Testing requires hands-on experience validating network-level data, detection logic, and high-throughput sensing systems in security-constrained environments.
This role supports development, modernization, and integration of sensing technologies including Open Sensor Platform (OSP), Full Packet Capture (FPCAP), Automated Security Validation (ASV), Intrusion Detection Systems (IDS), and emerging cyber sensors.

Requirements

• Active DoD Secret clearance.
• 3+ years of experience in cybersecurity, network, or systems testing.
• DoD 8570 IAT II or IAM I certification required (Security+, CySA+, CISM, CASP, CISSP or equivalent).
• Direct experience testing network sensors, packet-based systems, or cyber telemetry platforms.
• Strong understanding of networking fundamentals (TCP/IP, protocols, packet flows).
• Exposure to tools such as Wireshark, Zeek, Splunk, ACAS, Nessus, or similar.
• Experience testing in Linux-based or distributed environments.
• Ability to clearly document complex test scenarios and results.

Nice To Haves

• Experience with DevSecOps pipelines and automated regression testing.
• Familiarity with DoD cyber systems, RMF validation, or operational cyber defense environments.
• Bachelor’s degree in a related field or equivalent experience.

Responsibilities

• Perform hands-on integration, regression, performance, and verification & validation (V&V) testing across distributed sensing platforms.
• Validate network- and protocol-level data, including packet captures, flows, telemetry, and metadata generation.
• Test and validate detection logic, including analysis of false positives, false negatives, and sensor outputs.
• Execute high-volume data replay, load, stress, and throughput testing to assess sensor performance and stability.
• Validate end-to-end data pipelines across collection, analytics, storage, and reporting components.
• Conduct testing in Linux-based, distributed, and security-constrained lab, cloud, and operational environments.
• Document test results, defects, impacts, and recommended corrective actions.
• Collaborate closely with systems engineers, developers, and cybersecurity engineers to troubleshoot and resolve issues.
• Support Government test activities, including IV&V, operational testing, and test readiness events as required.
