Lyntris is a defense technology company that connects sensing to action across the connected battlespace. Lyntris brings together the talents of Accelint and Vitesse teams under one mission, with each contributing deep expertise within their domain. Combining differentiated hardware, software and mission expertise, Lyntris helps customers sense threats, make sense of complex conditions and act with greater speed, precision and confidence in contested environments.

Lyntris supports U.S. and allied defense organizations across every branch - including Navy, Army, Air Force, Space Force and allied partners - spanning strategic, operational and tactical missions and every domain:
Space, Air, Land, Sea and Cyber. With more than 200 active defense programs, Lyntris works at every level of the mission, from national command authority to the tactical edge.

Solutions are designed by operators who understand the mission, engineered for the conditions that degrade or defeat standard systems, and built on an open, modular architecture that integrates into existing programs without requiring them to start over. Lyntris moves faster than the traditional defense cycle - with integrated design, build and test capabilities in-house - and delivers systems that sustain and endure long after initial fielding.

• Senior Systems Integration & Dev Sec Ops  Engineer
• Full time
• Onsite

The Senior Systems Integration & Dev Sec Ops  Engineer is a hands-on engineering role focused on integrating and testing complex DoD software systems, building the tooling that makes that testing repeatable, and maintaining the secure pipelines and environments those systems deploy into. This engineer works across subsystem and external system boundaries, writes the automation that catches integration problems before formal test events, and builds tooling with an eye toward reuse beyond a single program.

This position supports the Beyond Line of Sight (BLOS) Engagement Controller and Manager (BECM) program and requires solid software integration engineering, test engineering, and Dev Sec Ops  experience in classified, highly regulated environments.

Full-time on-site in Sterling, VA, split between standard office space and SCIF work. Flexible daily start and end times, coordinated with program needs and facility access windows.

• Integrate and test software subsystems and external systems, identifying issues related to interface contracts, data exchange, timing, usability, functionality, safety, and security
• Write and maintain SWIT and SIT test threads, cases, and steps, and support traceability from requirements through verification evidence
• Participate in integration events with external system owners and government stakeholders, including dry runs, formal test events, and site activities
• Triage integration defects across system boundaries, isolate root cause, and work with the responsible team to drive closure

• Build and maintain test tooling: simulators, stubs, message injectors, data generators, log analyzers, and results reporting
• Develop automated test suites and utilities, and keep them current as subsystems and external interfaces change
• Extend automated regression coverage inside CI/CD so integration failures surface early rather than at test events
• Produce consistent test reporting and evidence artifacts for both engineering and compliance consumers

• Build tooling and test assets as versioned, documented components rather than one‑off scripts, so they hold up when another program picks them up
• Flag duplicated effort across teams and help consolidate it into shared components
• Contribute to common conventions for interface documentation, test structure, and environment configuration

• Use container technologies to configure and deploy software to…
