Software Development Engineer in Test (SDET)

Software Development Engineer in Test (SDET) ABOUT THE JOB Company Intro: TurbineOne is a fast-moving and high-performance startup with a mission to strengthen situational awareness for all Americans serving at our nation’s frontlines - and we are backed by the best DefenseTech venture capitalists. Our Frontline Perception System is an edge-first software platform that allows anyone, even with no technical knowledge, to build and use machine learning models within a comms-contested tactical environment. Our rapidly growing startup seeks a talented and mission-driven Software Development Engineer in Test (SDET) to join our dynamic team. In this role, you will own the quality, reliability, and performance of our platform across on-premise, air-gapped, and multi-platform deployments. You will design and implement automated test frameworks, validate complex system integrations, and ensure FPS performs seamlessly across diverse hardware, operating systems, and constrained network environments. As a critical partner to engineering and deployment teams, you will help deliver resilient software into high-stakes national security environments. If you thrive in fast-paced environments, care deeply about quality, and enjoy breaking complex systems to make them stronger, we want to hear from you. Job Title: Software Development Engineer in Test (SDET) Reporting to: Engineering Operations Manager Location: (Fully Remote) Geographically flexible for home-office with occasional travel required Primary Responsibilities: Design, build, and maintain automated test frameworks for FPS across on-prem and cloud environments. Develop end-to-end, integration, regression, and performance test suites for multi-platform deployments (Linux, Windows, edge devices, containerized systems). Own validation and verification processes for on-prem, air-gapped, and customer-specific deployments. Build CI/CD testing pipelines to support rapid iteration while maintaining system reliability. Create deployment validation scripts and health checks for infrastructure and application layers. Simulate comms-contested and resource-constrained environments to test system resilience. Collaborate closely with engineering, DevOps, and field integration teams to identify edge cases and prevent production defects. Troubleshoot complex system-level issues spanning application, networking, containerization, and hardware interfaces. Develop reproducible test environments using virtualization and container orchestration tools. Document test strategies, deployment validation procedures, and release readiness criteria. Continuously improve testing methodologies to support rapid scaling and evolving customer requirements. On a Typical Day You Would: Write automated integration tests to validate FPS workflows. Build and maintain CI pipelines that test containerized deployments before release. Spin up a simulated air-gapped environment to reproduce and debug a customer-reported issue. Validate FPS across multiple operating systems and hardware configurations. Design a stress test to evaluate system performance under limited bandwidth conditions. Collaborate with engineers to identify root causes of deployment failures. Create scripts to automatically verify installation, configuration, and system health checks. Participate in release reviews to ensure readiness for field deployment. Improve test coverage across APIs, UI components, ML pipelines, and system integrations. Desired Experience and Attributes: High standard of ethics, grit, integrity, and moral character. 5+ years of experience in software testing, quality engineering, or SDET roles. Strong programming skills (Python preferred) and experience building automated test frameworks. Experience testing on-premise, air-gapped, or enterprise deployments. Strong understanding of Linux systems, networking fundamentals (LAN vs WAN, ssh, IP, DHCP), and containerization (Docker, Kubernetes). Experience ... (truncated, view full listing at source)
