Cybersecurity Engineer - Clearance Required

Overview

We’re looking for a Cybersecurity Engineer to support the secure deployment and continuous authorization of LIGER, an enterprise AI platform built for federal missions for a DHS customer. You’ll join a small, high-visibility team and own the security work that lets LIGER reach production, maintaining the ATO posture, driving vulnerability management, and partnering with cyber stakeholders to keep the platform compliant as it evolves. This position requires a CBP Background Investigation;  U.S. citizenship is required.

 

This is hands-on cyber engineering, not paper compliance. You’ll work alongside platform engineers, ISSOs, and the security team to harden deployments, validate controls, and resolve findings against real systems. If you want to do federal cybersecurity in an environment that ships fast and treats security as part of the product, keep reading.

 

LIGER sits within LMI’s Chief Technology Office. We’re a small, high-visibility team building AI tools for federal agencies. The culture is more startup than traditional government contractor; we move fast, solve problems in design spikes rather than scheduled reviews, and care more about outcomes than process. That said, we’re building for users who need reliability and trust, so craft and attention to detail matter, especially in security.

 

You’ll work daily with the platform lead, engineering team, and product manager, and directly with cyber stakeholders. Security and compliance are foundational to how LIGER ships, and this is a real opportunity to define how the platform maintains its authorization while continuing to iterate.

 

LMI is a new breed of digital solutions provider dedicated to accelerating government impact with innovation and speed. Investing in technology and prototypes ahead of need, LMI brings commercial-grade platforms and mission-ready AI to federal agencies at commercial speed.  

  

Leveraging our mission-ready technology and solutions, proven expertise in federal deployment, and strategic relationships, we enhance outcomes for the government, efficiently and effectively. With a focus on agility and collaboration, LMI serves the defense, space, healthcare, and energy sectors—helping agencies navigate complexity and outpace change. Headquartered in Tysons, Virginia, LMI is committed to delivering impactful results that strengthen missions and drive lasting value.  

Responsibilities

What You’ll Do

 

• Lead Risk Management Framework (RMF) activities for the LIGER deployment, including system categorization, control selection and tailoring, implementation, assessment, and continuous monitoring

• Own and maintain authorization artifacts: System Security Plan (SSP), Security Assessment Plan (SAP), Security Assessment Report (SAR), Plan of Action and Milestones (POA&M), and supporting                     documentation aligned to DHS requirements

• Coordinate directly with ISSOs, Authorizing Officials, and cyber working groups to advance ATO and continuous authorization activities

• Interpret NIST 800-53 controls in the context of the LIGER platform and translate them into actionable engineering requirements

• Run and review vulnerability scans across CI/CD pipelines and runtime environments, triage findings, and drive remediation through the engineering team

• Validate secure configurations and hardening baselines (e.g., CIS Benchmarks, DISA STIGs) on containers, hosts, and cloud resources

• Partner with platform engineers on cloud and container security in AWS GovCloud, including IAM, network controls, secrets management, logging, and runtime protection

• Develop and maintain security policies, procedures, and standard operating procedures (SOPs) specific to LIGER on customer infrastructure

• Track audit findings, remediation actions, and POA&M items to closure

• Support FedRAMP-aligned control implementation and inheritance where applicable

• Advise senior LIGER and leadership on system risk levels, control effectiveness, and emerging compliance considerations for AI/LLM systems in federal environments
