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 validating software across multiple operating systems and hardware environments. - Familiarity with CI/CD systems and infrastructure-as-code tools. - Experience performance testing distributed systems or ML-driven applications. - Excellent debugging and root-cause analysis skills across full-stack systems. - Strong written and verbal communication skills. - A college degree in Computer Science, Engineering, or related field is preferred. **Startup Culture Expectations:** - We’re a small, fully remote team, and everything is our responsibility. - Our team thrives on autonomy, trust, and solid communication. - Everyone on the Team needs to be very comfortable with constant change, moving fast, sharing failures, embracing grit, and building things themselves. **Eligibility:** - Must be eligible to obtain a clearance with the U.S. government.
