Core4ce is seeking an experienced F5 Advanced Web Application Firewall (AWAF) Engineer to support the secure operation of enterprise web applications and application programming interfaces (APIs).
The successful candidate will work closely with the cybersecurity team to define WAF policy baselines for individual systems and applications. This individual will collaborate with system owners, application teams, and infrastructure personnel to validate expected application behavior, tune policies, reduce false positives, and maintain effective security enforcement.
The role will also support application security alert-response activities by analyzing WAF events, identifying potentially malicious activity, coordinating with appropriate stakeholders, and assisting with investigation, documentation, and mitigation.
Responsibilities:
WAF Policy Engineering and Administration
- Design, configure, implement, and maintain F5 Advanced WAF/ASM policies for enterprise web applications and APIs.
- Develop application-specific WAF policy baselines based on application architecture, functionality, data sensitivity, business risk, and security requirements.
- Work with the cybersecurity team to establish repeatable WAF standards, policy-development procedures, and enforcement criteria.
- Onboard new applications and services into the F5 WAF environment.
- Configure and maintain protections for common web application and API attacks, including:
- OWASP Top 10 threats
- Signature-based attack detection
- Protocol violations
- Malicious file and payload types

- Apply policy changes in accordance with change-management and cybersecurity procedures.
Policy Tuning and System Owner Collaboration
- Partner with system owners, application developers, and infrastructure teams to understand legitimate application behavior.
- Tune WAF policies to protect applications while maintaining availability and operational performance.
- Investigate false positives and determine whether blocked or flagged requests represent legitimate business activity, application defects, or malicious behavior.
- Recommend corrective actions for application issues identified through WAF policy analysis.
- Review policy effectiveness and make improvements based on application changes, threat intelligence, vulnerability assessments, and observed attack patterns.
- Maintain clear documentation of application-specific requirements, policy decisions, exceptions, and tuning activities.
Alert Analysis and Incident Support
- Monitor and analyze WAF violations, security events, blocked requests, and anomalous traffic.
- Assist the cybersecurity team with alert triage and response activities.
- Investigate suspected attacks, including SQL injection, cross-site scripting, command injection, path traversal, protocol abuse, automated attacks, and other web-based threats.
- Correlate WAF events with application, network, endpoint, and security-monitoring data when necessary.
- Validate suspicious activity with system owners and other technical stakeholders.
- Escalate significant or confirmed events in accordance with incident-response procedures.
- Support containment, mitigation, and follow-up actions, including temporary policy changes or blocking controls when appropriate.
- Prepare incident summaries, technical findings, and recommendations for remediation.
- Identify recurring attack patterns and recommend improvements to WAF policies and broader security controls.
This position is designed to be flexible, with responsibilities evolving to meet business needs and enable individual growth.
Requirements:
- U.S. Citizen
- Ability to obtain and maintain an active Secret security clearance.
- Bachelor’s degree in cybersecurity, computer science, information technology, or a related technical field, or equivalent practical experience.

- Demonstrated experience developing, deploying, administering, and tuning F5 WAF policies.
- Experience establishing application-specific WAF policy baselines and enforcement requirements.
- Experience working directly with application owners, developers, and infrastructure teams to analyze application behavior and resolve false positives.
- Experience analyzing WAF logs, violations, security events, and blocked traffic.
- Working knowledge of web application and API security concepts, including:
- HTTP and HTTPS
- TLS
- HTTP methods, headers, cookies, and sessions
- URLs, parameters, and payloads
- JSON and XML
- REST APIs
- Authentication and authorization
- Strong knowledge of common web application vulnerabilities and attack techniques, including the OWASP Top 10.
- Experience assisting with cybersecurity alert triage, incident investigation, or incident-response activities.
- Ability to document technical findings, policy decisions, exceptions, and recommended actions.
- Excellent written and verbal communication skills.
Preferred Qualifications:
- F5 Certified Technology Specialist certification or equivalent F5 AWAF/ASM experience.
- Experience with F5 BIG-IP administration and related technologies, including LTM, APM, iRules, Local Traffic Policies, and SSL profiles.

Tips for Your Remote Firewall Engineer Job Search
Apply early to remote roles that fit
Migrate Mate lists remote firewall engineer openings from across the U.S. in one place, so you can find roles that match your experience and apply directly without sorting through non-remote listings mixed in.
Show async communication skills upfront
Remote firewall engineer teams rely on written handoffs, ticketing systems, and documentation over real-time calls. Include examples of runbooks, change-management notes, or firewall policy documentation you've written to signal you can communicate clearly without being in the room.
Highlight remote-ready tooling on your resume
Name the specific remote network management platforms you've used, such as cloud-based SIEM tools, remote access VPN administration, and configuration management platforms like Ansible or Terraform for network policy. Generic firewall skills matter less than demonstrating you've operated them in a distributed environment.
Prepare for remote-first technical interviews
Remote firewall engineer interviews often include a live troubleshooting exercise over screen share or a written scenario where you diagram a firewall policy change. Practice walking through your reasoning in writing and explaining your decision process clearly, since interviewers can't observe your body language.
Remote Firewall Engineer Jobs: Frequently Asked Questions
How do I get a remote firewall engineer job?
Target companies with distributed security teams, remote-first policies, or managed security service provider models, as these organizations are most likely to hire firewall engineers without an on-site requirement. Remote employers screen heavily for self-direction, clear written communication, and proficiency with tools like Palo Alto Networks, Fortinet, and Cisco ASA. Demonstrating hands-on experience with VPN configuration, firewall policy management, and remote network monitoring gives your application a real edge.
Which companies hire remote firewall engineers?
Companies hiring remote firewall engineers right now include ECI, Core4ce, and GuidePoint Security, based on current remote listings on Migrate Mate as of November 2026. The employers most active in this space tend to be remote-first technology firms, managed security service providers, and financial services organizations operating distributed infrastructure teams.
Can you get a remote firewall engineer job with no experience?
Yes, but remote entry-level firewall engineer roles are harder to land because employers expect you to troubleshoot independently without in-person support. Companies most open to entry-level remote candidates include smaller managed security providers and cloud-focused startups. A home lab, personal projects showing firewall policy work, or a CompTIA Security+ or vendor-specific certification can substitute meaningfully for formal job history.
Do you need a degree for remote firewall engineer jobs?
Not always. Many remote employers care more about hands-on firewall skills, vendor certifications like PCNSE or CCNP Security, and demonstrated results than a four-year degree. What consistently opens doors is a portfolio of real work, such as network diagrams, firewall rule audits, or documented incident responses, paired with certifications that signal technical depth.
Which industries hire the most remote firewall engineers?
Most remote firewall engineer openings sit in Energy, Technology & Software, and Investment & Asset Management, per current remote listings on Migrate Mate as of November 2026. These sectors rely on distributed teams managing geographically spread infrastructure, which makes remote firewall engineering a practical and common staffing model for them.
