Description
Arlington, VA or New York, NY (on-site/hybrid)
The platform: a privacy-first mobile carrier built from the ground up, running its own network rather than a layer over legacy infrastructure. Secure cellular service for consumers, businesses, and government agencies, with privacy and security engineered into every layer of the stack. Series C closed in March 2026, scaling fast.
The role: the technical operator who makes the product work in the field for the customers who depend on it most. Embedded with federal and national security customers, sitting at the seam between business development and engineering. The customer's technical advocate inside the company, and the company's technical advocate inside the customer's building. Small, high-trust team writing its own playbook.
The work:
Own technical delivery into federal and national security environments, from first prototype through operational acceptance and sustainment
Embed with customer teams worldwide to learn the workflows, threat models, and constraints that never make it into a requirements document
Configure, integrate, and tune mobile core capabilities against each mission profile
Run pilots, exercises, and demos structured to produce decision-quality evidence, not theater
Provide live technical support during operations and incidents; run root-cause analysis and push preventive fixes into the platform
Write production-grade code for the glue, integrations, tooling, and one-off capabilities that unblock deployments
Prototype features in the field, validate against real mission use, and hand successful patterns to core engineering
Translate mission requirements into prioritized engineering asks, and engineering constraints back into operator language
Partner with BD and solutions architects to convert pilots into programs of record
Required:
2+ years in a software engineering or forward-deployed engineering role
Swiss-army-knife technical range: code, debug networking, reason about systems-level tradeoffs, learn fast
Strong at scoping ambiguous problems and sequencing delivery without explicit instruction
Sharp written and verbal communication, equally fluent briefing a flag officer, writing an engineering ticket, and running a customer working session
High ownership and resourcefulness, including the unglamorous parts
U.S. citizenship and eligibility for a U.S. Top Secret clearance (active TS strongly preferred)
Willingness to travel up to 50% to customer sites, military installations, and partner locations
Nice to have:
Active TS/SCI
Prior military service, government civilian experience, or time in comms, signals, cyber, or intelligence roles
Customer-facing technical background at a defense tech startup
Mobile networks, telecom, networking infrastructure, or cybersecurity depth
Early engineer or operator experience at a sub-100-person company
Track record of taking field-driven feature work into a core roadmap
Compensation: $180k to $230k for Arlington, VA, or New York, NY, depending on experience and interview performance, plus meaningful equity.
