Role Summary
The Cyber Security Engineer is
responsible for supporting NIST CSF / NIST 800 assessments, triaging
penetration test findings, and driving remediation activities across
application, infrastructure, network security, and monitoring platforms.
The role is hands-on and delivery
focused, working closely with architects, platform owners, SOC, and
infrastructure/application teams to translate security findings into actionable
fixes, validate control effectiveness, and support audit‑ready evidence for
regulated/government environments.
Key Responsibilities
NIST Assessment Support (CSF / NIST 800
Series)
- Support
NIST CSF / NIST 800‑53 / 800‑61 / 800‑92 assessments through:
- Control
evidence collection
- Gap
analysis support
- Mapping
tooling controls to NIST requirements
- Assist
architects and governance teams in preparing:
- Control
implementation summaries
- Tool
capability mapping
- Evidence
packs for audits and client reviews
- Track
and manage security gaps, risks, and remediation actions in line with
agreed timelines
- Support
continuous improvement initiatives driven by assessment outcomes
Penetration Test Findings &
Remediation
- Triage
and analyse application, infrastructure, and network penetration test
findings
- Work
with platform and application teams to:
- Validate
findings (true positive vs false positive)
- Prioritise
remediation based on risk and exploitability
- Execute
or support remediation actions such as:
- Configuration
hardening
- Policy
tuning
- Control
enablement or enhancement
- Track
remediation status and provide clear closure evidence for governance and
audit forums
Hands‑on engineering support across:
- Endpoint
& Infrastructure Security
- Vulnerability
& Exposure Management
- Activities
include:
- Policy
tuning and baseline hardening
- Coverage
and health checks
- Supporting
remediation of vulnerabilities and misconfigurations
- Validating
fixes post‑remediation
Support security controls across:
- Cisco
security platforms
- Imperva
- Microsoft
GSA / related network security controls
Responsibilities include:
- Supporting
firewall / network security rule reviews and clean‑ups
- Assisting
with remediation of network‑related pen test findings
- Supporting
change validation and post‑implementation checks
- Working
with network teams to ensure security controls align with NIST and secure‑by‑design
principles
- Support
SIEM and monitoring platforms:
- Splunk
- Microsoft
Sentinel
- Assist
with:
- Log source onboarding validation
- Detection coverage checks related to NIST and
pen test scenarios
- Validation that remediated controls generate
expected telemetry
- Support
SOC teams with investigation data where required
- Maintain
accurate documentation for:
- Remediation
actions
- Control
changes
- Evidence
required for audits and MSSR / governance reviews
- Participate
in:
- Incident and problem reviews (P1 / P2 support)
- Root cause analysis where control gaps are
identified
- Follow
structured change and release processes (CAB, validation, rollback awareness)
Skills &
Experience
- 5 years experience in security engineering / SecOps / blue team
roles
- Exposure to NIST CSF or NIST 800 frameworks
- Hands‑on experience supporting remediation across:
- Endpoint / infrastructure
security tools
- Vulnerability management
platforms
- Network security controls
- Experience working with penetration test reports and remediation
tracking
- Familiarity with SIEM platforms (Splunk and/or Sentinel)
- Strong documentation and evidence‑driven mindset (audit readiness)
