End-to-end vulnerability management: scanning, validating false positives, remediating, retesting, and documenting closure
Linux administration on RHEL or CentOS, shell scripting, and SIEM log integration such as Splunk
Technical writing strong enough that control narratives hold up under assessor review
Bachelor's degree in Engineering, Computer Science, Cybersecurity, or Information Systems, or equivalent hands-on experience

## Description

POSITION OVERVIEW The Senior Cybersecurity Integration Engineer secures and integrates the Customer's enterprise API gateway, drives it through the Risk Management Framework to a signed Authority to Operate (ATO), and keeps it authorized. The role pairs hands-on security engineering at the API boundary with ownership of the System Security Plan and the continuous monitoring that sustains it. Requires an active Moderate Background Investigation (MBI) at start.
RESPONSIBILITIES Design and enforce API security policy - authentication, authorization, token validation, rate limiting, payload validation, threat protection
Manage TLS, mutual TLS, and certificate and key lifecycle across all environments and trust relationships
Onboard applications, vendors, and SaaS services, coordinating firewall, proxy, DNS, and load balancer changes with owning teams
Integrate the gateway with enterprise identity and federation services
Harden gateway and hosts to STIG/SCAP and feed security telemetry to the enterprise SIEM
Promote configuration through the Customer's environments under Government change control
Author and maintain the SSP and control narratives against NIST 800-53 Rev 5, covering boundary, inventory, inheritance, and tailoring
Run the RMF package to ATO: evidence, assessor walkthroughs, finding resolution
Sustain ConMon: recurring scans, false positive validation, remediation and retest, POA&M closure, deviation requests, monthly reporting
Perform security impact analysis on changes and troubleshoot across gateway, network, identity, and application layers
