Cyber Defense Analyst

Job Description

Company: Ridgeline International, LLC

Location: Tysons, US

We were early to the fight against Ubiquitous Technical Surveillance, and we’ve been pushing the edge ever since.

Our mission is to help government and enterprise organizations understand and manage commercial data risks, shape their digital signatures, and operate with confidence in an increasingly complex information landscape. We build and integrate advanced, tech-forward solutions to problems our customers often don’t know they have – until it matters most.

We move fast, think critically, and deliver where it counts.

What’s in it for you?

We work hard and do fun things.

You’ll work on high-impact, technically challenging problems alongside a team that values teamwork over competition. Veilant offers a solid work-life balance and flexible remote work options. At Veilant, you’ll work with the most talented software developers, systems engineers, and subject matter experts, building tools and systems that make a real difference.

Job Description

Veilant is looking for a Cyber Defense Analyst to join our Information Security team and help defend our enterprise environment against active and emerging cyber threats.

In this role, you will monitor network and endpoint activity, investigate security alerts, tune detections, and help surface anomalous behavior across our SIEM and EDR stack, including Microsoft Defender for Endpoint, Elastic, and Splunk.

This role is ideal for someone with a strong technical foundation, curiosity about how systems behave, and hands-on interest in alert triage, detection engineering, threat hunting, and incident response.

What You’ll Do

• Monitor endpoint and network activity using Microsoft Defender for Endpoint, Elastic, Splunk, and related security tools.
• Triage and investigate alerts, distinguishing benign activity from suspicious or malicious behavior.
• Develop, tune, and maintain detections using KQL, ES|QL, SQL, SPL, or similar query languages.
• Translate threat intelligence, IOCs, TTPs, and emerging threat reporting into actionable detections, dashboards, queries, and hunts.
• Conduct targeted threat hunts using frameworks such as MITRE ATT&CK.
• Document incidents, including timelines, indicators, scope, findings, remediation steps, and lessons learned.
• Build dashboards and visualizations that improve visibility into enterprise activity and anomalies.
• Contribute to playbooks that improve the team’s speed, consistency, and effectiveness during investigations.
• Collaborate with security, IT, and Engineering teams to support investigations and response activities.

What Success Looks Like

In the first six months, you will build a working understanding of Veilant’s environment, independently triage alerts, improve detection logic, contribute to threat hunts, document incidents, and help strengthen playbooks that make the team faster and more effective.
