Top Tech Jobs & Startup Jobs in Los Angeles, CA

Build and operate the infrastructure supporting Legion, including CI/CD pipelines, infrastructure as code, Kubernetes environments, observability, and deployments across cloud, on-premises, and customer environments. Improve developer tooling, support secure and compliant platform operations, and assist with deployments to customer and test sites. The role requires strong Linux, networking, scripting, containerization, and production infrastructure experience, with potential support for air-gapped and mission-critical systems.

Develop and optimize detection, tracking, and multi-sensor fusion algorithms (Kalman/particle filters, multi-target tracking) for resource-constrained UAVs. Train and deploy neural networks for ATR, design distributed swarm fusion, validate against flight data and simulation, and optimize models for real-time edge inference. Travel up to 25% for tests.

Own full-cycle recruiting for manufacturing, industrial, quality, tooling, and production roles across sites in Oxnard and Northwest Arkansas. Build talent pipelines through schools, trade programs, manufacturers, veterans, and community partners while supporting factory launches and production scaling. Recruiters may also support aircraft, supply chain, and operations hiring. The role requires strong manufacturing knowledge, high-growth hardware recruiting experience, and the ability to hire both hourly and leadership talent.

Own full-cycle recruiting for mission, defense business development, business operations, finance, real estate, and marketing roles. Lead senior and first-of-kind searches, advise hiring managers, build talent pipelines, recruit defense and national security professionals, and close high-impact candidates. The role requires strong market knowledge, executive search capability, and credibility across defense, government, and startup environments.

Own top-of-funnel sourcing for software engineering roles, including backend, frontend, autonomy, and forward-deployed positions. Within the first year, expand into sourcing aircraft talent across propulsion, structures, avionics, manufacturing, and production. Responsibilities include researching candidates on GitHub, writing personalized outreach, building effective searches, managing requisitions, maintaining accurate recruiting data, and partnering directly with hiring managers in a fast-paced defense technology startup.

Develop on-vehicle and simulation software across the autonomy stack: planning behaviors, sensor and payload integration, embedded/vehicle platforms, realistic UxS simulation, and electronics prototyping. Ensure reliable, testable code and support onsite test/integration events (up to 25% travel).

Define and own autonomy architecture for large-scale UAV swarms: design perception, planning, control, and inter-robot/C2 protocols; make system tradeoffs; mentor engineers; write production-quality code; support test events (up to 25% travel).

Embed with U.S. government and military customers to deploy, integrate, debug, and maintain C2 software in austere operational environments. Build integrations, troubleshoot distributed systems, contribute to core services, support on-call and nonstandard hours, and travel extensively to ensure mission reliability and deliver field-driven product improvements.

Lead and own Legion's software roadmap, architecture, and delivery across autonomy, mission/C2, full-stack and field-deployed engineering. Build and scale the software organization, define technical standards for real-time and multi-agent systems, drive engineering execution, recruit talent, establish field feedback loops, interface with customers and investors, and adopt frontier AI tools to improve system performance and reliability.
