We specialize in cybersecurity, customer experience, cloud infrastructure, and advanced technologies such as Large Language Models (LLMs). Our mission is to assist our customers in their business strategies utilizing their data to make more intelligent decisions. As a well-funded early-stage startup, Gruve offers a dynamic environment with strong customer and partner networks.

About the Role

The Network Security Engineer will join the US Solutions Delivery team, implementing and supporting enterprise firewall and network security solutions across customer environments. This is a hands-on, delivery-focused role centered on Cisco ASA and FTD platforms, and NGFW deployments. The engineer owns assigned workstreams end-to-end - from lab validation through production cutover — and works closely with architects, project managers, and customer stakeholders. The engineer should be US Citizen and willingness to travel is required.

Key Responsibilities

Firewall Deployment & Operations

  • Implement and configure enterprise firewall and network security solutions (NGFW/FTD, VPNs, NAT, NAC/ISE, SASE) in alignment with approved designs
  • Manage and maintain firewall policies, including access rules, NAT, objects, zones, and security profiles following best practices
  • Perform testing and validation of firewall rules and security configurations in lab or staging environments before production deployment

Migration & Troubleshooting

  • Support firewall migrations from Cisco ASA and third-party platforms to Cisco FTD
  • Troubleshoot and resolve firewall and network security issues, including traffic drops, NAT issues, VPN failures, and routing/DNS/DHCP dependencies
  • Identify and implement opportunities for optimization and automation, such as rule cleanup, standardization, and workflow improvements

Execution & Coordination

  • Collaborate with architects, senior engineers, and project managers to ensure accurate and timely solution delivery
  • Participate in project sync-ups and technical discussions to understand requirements, scope, and deployment sequencing
  • Take ownership of assigned tasks end-to-end, including escalation, root cause analysis (RCA), and issue resolution

Documentation & Continuous Improvement

  • Create and maintain comprehensive documentation, including firewall rules, network diagrams, VPN inventories, and operational runbooks
  • Stay current on firewall platforms, SASE, Zero Trust, and network security practices, applying new learnings to day-to-day delivery work

Basic Qualifications

  • Candidate should be a US citizen.
  • Bachelor’s degree in computer science, Information Technology, Cybersecurity, or related field
  • 4-7 years of experience in cybersecurity, with a strong focus on firewall design and implementation
  • 3+ years of hands-on experience designing and implementing Cisco ASA and Cisco FTD firewall environments or any third-party firewalls such as Palo Alto/Fortinet/Checkpoint experience with limited Cisco Firewall experience.
  • Proven expertise in troubleshooting firewall and VPN connectivity issues, including NAT, routing, and policy-related problems
  • Good understanding of NGFW features such as malware protection, threat detection, URL filtering, SSL decryption, and Intrusion Prevention Systems (IPS); hands-on experience preferred
  • Experience working with multi-instance firewall environments
  • Strong understanding of core networking concepts: TCP/IP, DNS, DHCP, subnetting, NAT, VPNs, and routing/switching fundamentals
  • Willingness to travel across the U.S. to support customer deployments and firewall rollouts.

Preferred Qualifications

  • CCNP Security certification or equivalent demonstrated expertise
  • Experience with Cisco Secure Access, Umbrella, or XDR platforms.
  • Knowledge of Zero trust/SASE implementations.
  • Knowledge of Cisco ISE for NAC/802.1X integration alongside firewall deployments
  • Experience with security automation and scripting (Python, Ansible, APIs)
  • CISSP, GIAC, or other industry-recognized security certifications
  • Familiarity with compliance frameworks (PCI-DSS, HIPAA, SOC 2, NIST)
  • Prior experience in a consulting, professional services, or partner-led delivery model

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
