Forward Deployed Engineer, Federal

ABOUT CAPE Cape is America’s privacy-first mobile carrier. Our mission is to be a force for good in global wireless. Cape was founded in 2022 by people who believe privacy is a fundamental right, not a luxury to be traded away. Our journey began when our founder recognized a critical vulnerability in our modern world: everyone relies on the same stagnant cellular infrastructure and legacy systems that track our every movement, monitor and profile our connections, and lose and sell our personal data. Instead of accepting the status quo, we decided to fix it. National security professionals, journalists, parents, and everyone in between can stay connected and have privacy. We didn’t just build a layer on top of old tech; we built America’s most private and secure mobile carrier from the ground up. By building our own network from scratch, we are able to design and build a suite of privacy and security features that no other carrier on the planet can offer. Today, Cape provides our secure network to consumers, businesses, and government agencies alike. We closed our Series C in March 2026, and we are scaling rapidly, with the goal of giving people back control of their most personal information. THE TEAM At Cape, we are the architects of a privacy-centric movement that is just getting started. We are relentless builders, constantly innovating at the edge of what’s possible in telecommunications. We operate on a foundation of high trust and high expectations. As a member of our team, you will collaborate with world-class engineers, architects, and visionaries, and work across organizational lines to solve "impossible" problems and deliver mission-critical results for our users every single day. THE ROLE Forward Deployed Engineers (FDEs) are the technical operators who ensure Cape’s products actually work in the field for the customers who depend on them most. In a world of demo-ware and big promises, an FDE delivers tangible outcomes: they embed with federal customers, translate ambiguous mission needs into working software, and feed hard-won demand signal back into product and engineering. This is a hands-on builder role at the seam between Business Development and Engineering. You will be the customer’s technical advocate inside Cape and Cape’s technical advocate inside the customer’s building. You will scope deployments, prototype integrations, troubleshoot live issues on production networks, and pull engineering priorities directly from operator pain. Where the product doesn’t yet do what the mission requires, you will build the bridge—and then push the durable fix into the roadmap. FDE is a small, high-trust team. We're building this together. You will not be handed a playbook, you'll help write it. WHAT YOU WILL DO Customer Deployment & Delivery - Own the technical delivery of Cape’s products into federal and national security customer environments—from first prototype through operational acceptance and sustainment - Embed with customer teams around the world to understand workflows, threat models, and constraints that don’t appear in any requirements document - Configure, integrate, and tune Cape’s mobile core capabilities against the specific mission profile of each deployment - Lead customer exercises, pilots, and demonstrations; structure them to produce decision-quality evidence rather than theater - Provide direct technical support during live operations and incidents; conduct root-cause analyses and drive preventive fixes back into the platform PROTOTYPING & ENGINEERING - Write production-grade code to build the glue, integrations, tooling, and one-off capabilities that unblock customer deployments - Prototype new product features in the field, validate them against real mission use, and work with core engineering teams to expand on successful hypotheses - Make sound tradeoffs between bespoke customer work and reusable platform investment—default toward the platform when the pattern repeats BRIDGE BETWEEN CUSTOMER, PR
