We are an in-office company, and our expectation is that full-time employees primarily work from their Applied Intuition office 5 days a week. However, we also recognize the importance of flexibility and trust our employees to manage their schedules responsibly. This may include occasional remote work, starting the day with morning meetings from home before heading to the office, or leaving earlier when needed to accommodate family commitments. This in-office expectation does not apply to contractor positions

ABOUT THE ROLE

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
