SENIOR NETWORK AUTOMATION ENGINEER - CYBERSECURITY

Trinity Cyber pioneered active network defense — preemptive security that surgically removes threats from live traffic before attackers can establish presence on endpoints and networks. While competing Detection & Response approaches demand alert triage and reactive firefighting, our Full Content Inspection™ capability meets adversaries in the network and cleans malicious content from protocols, code, and files in real time — with sub-millisecond inspection latency and near-zero false positives. Every day, we work at scale: protecting over 3 million users and processing 1.5 trillion content objects.

Position

Full-time

We build and maintain the high-performance backbone that allows our products to actively secure and defend our customers against global cybersecurity threats in real-time. As a Senior Network Automation Engineer, you aren’t just managing a network; you are ensuring the delivery of a critical security mission. We are looking for a seasoned professional—someone with 10+ years of experience—who understands that a truly great network is one that is silent, stable, and meticulously engineered.  You will work in a private hosted environment without access to public cloud tools. This is a fully remote position that requires US citizenship due to federal contract requirements.

How We Work:

  • Strategic Autonomy: We hire self-starters and give them the space to innovate. As a senior member of the team, you will operate with minimal direction. We don't micromanage; we provide the objective and trust you to architect the solution.
  • Sophistication & Scale: You will tackle high-complexity work (Puppet, Foreman, and enterprise data center environments) in a low-bureaucracy setting. We’ve removed the corporate fluff so you can focus on the craftsmanship of infrastructure.
  • Remote Excellence: Enjoy the flexibility of a 100% remote role while collaborating with a high-caliber team that values technical integrity above all else.

What You’ll Do:

  • Empower Protection: Maintain and optimize the complex firewall and VPN architectures that enable our security products to actively shield and defend our customers.
  • Architect & Automate: Use Python and modern automation frameworks to build a network that manages itself. You’ll replace manual repetition with robust, testable code.
  • Strategic Troubleshooting: Take point on complex Layer 2/Layer 3 and dynamic routing (BGP) challenges. You are the final point of escalation who identifies the root cause and implements a permanent fix.
  • Design for Resilience: Continuously evaluate and improve our network architecture to increase performance, security, and stability.

Core Requirements:

  • Experience performance tuning Linux systems, particularly related to networking.
  • Experience with networking concepts and debugging tools tcpdump/wireshark.
  • Knowledge of basic networking including L2 and L3 fundamentals, stateful devices (firewalls, proxies), etc.
  • Understanding of basic protocols (LACP, LLDP, ARP, ND, IP (v4/v6), TCP, UDP, BFD, HTTP, SMTP, TFTP, IKE/ESP, TLS).
  • Familiarity with networking concepts like dynamic routing (OSPF, iBGP/eBGP, filter-based forwarding, rpm/event scripts), ISP/IX full table peering and multi-ISP environments.
  • Experience working with any/all of Nautobot, Telegraf/InfluxDB/Grafana, Elasticsearch/Logstash/Kibana, and other automation and monitoring tools are strongly preferred.
  • Experience with any/all of Juniper (especially QFX5K based EVPN environments), VMware NSX-T, F5 BIG-IP (primary focus on SSLO), Palo Alto NGFW and Panorama would also be a big plus.
  • Familiarity with issues surrounding application layer proxying of network protocols.
  • Python application development knowledge and experience.
  • Proven ability to learn quickly and solve significant problems with minimal direction.
  • Willingness to perform deep research and/or reverse engineer poorly documented standards.
  • Bachelors degree in Computer Science, Technology, Engineering, or Math is preferred.
  • Impeccable troubleshooting skills and ability to rapidly understand the basic design and operation of new systems.
  • Must possess the highest level of personal integrity, value team success over individual achievement, and enjoy working on a fully remote team in a very high tech environment.
