Network and Security Engineer, Defense at Applied · LumiJobs

Responsibilities

We are looking for a Network and Security Engineer to own the architecture of high-performance, high-assurance networks for our defense programs. You will design networks that move terabits of radar, camera, and vehicle data with low, predictable latency, and you will secure those networks to the standard needed for classified environments up to Impact Level 6 (IL6). This is a senior, hands-on individual contributor role for someone who has spent a career solving hard networking and security problems and wants to keep doing so directly, while shaping technical direction across our defense programs and growing into broader technical leadership. At Applied, we encourage engineers to own technical and product decisions, work closely with customers and users, and contribute to a thoughtful, dynamic team culture.
At Applied Intuition, you will:
Architect and build high-bandwidth network fabrics (100/400/800GbE) that carry mixed radar, EO/IR camera, and vehicle bus data from the sensor edge to compute and storage
Design for deterministic, low-latency transport using techniques such as Time-Sensitive Networking (TSN), precision time synchronization (PTP/IEEE 1588), RDMA/RoCEv2, and multicast for sensor distribution
Bridge in-vehicle networks (automotive Ethernet, CAN, and legacy military buses) with modern IP-based backbones in rugged, size- and power-limited platforms
Design and implement security architectures that support IL5/IL6 accreditation, including network segmentation, encryption in transit (MACsec, IPsec, CSfC-style layered encryption), PKI, and cross-domain data flows
Apply zero trust principles across on-prem, tactical edge, and cloud environments rather than relying on perimeter-only defenses
Automate network and security configuration with infrastructure as code, and build continuous compliance checks into deployment pipelines in place of manual, document-driven processes
Build observability into the network through streaming telemetry, flow analysis, and security monitoring so that problems and threats surface quickly
Translate Navy and DoD guidance into practical engineering decisions, adopting the intent of those standards while pushing toward modern, maintainable solutions
Work directly with customers, government stakeholders, and product teams across Applied to understand mission needs and deployment constraints
Set the technical roadmap for defense networking and security, lead design reviews, mentor engineers across teams, and serve as a trusted technical voice with customers and government stakeholders
