Top Tech Jobs & Startup Jobs in San Francisco Bay Area, CA

Design and implement SDN-based network architecture for a multi-orbit satellite constellation. Develop routing, topology management, fast-reroute, traffic engineering, telemetry/observability, and self-healing control-plane/data-plane solutions optimized for latency, power, and mobility. Collaborate with RF and silicon teams and mentor junior engineers.

Design and implement SDN and routing solutions for a multi-orbit satellite constellation: routing, topology management, fast-reroute, telemetry-driven self-healing, packet forwarding, and observability. Collaborate with RF and silicon teams and mentor junior engineers.

Design, implement, and test MAC control-plane software for satellite links, including TDMA/DAMA scheduling, QoS, link-state machines, hardware integration (PHY, FPGAs, modems), and simulation/testing to validate performance under mobility and failure scenarios.

Design and implement MAC control-plane software for satellite point-to-point and point-to-multipoint links. Develop schedulers, admission-control, state machines, QoS, flow control, and link-adaptation logic. Define interfaces to PHY/modem/hardware, evaluate centralized vs. distributed architectures, build simulation and test capabilities, and lead development through hardware integration, qualification, and deployment.

Lead design and implementation of multi-threaded embedded C/C++ software for Linux/RTOS/bare-metal on multi-core SoCs. Develop drivers and data/control plane functions for RF, antenna, and optical systems; integrate software with hardware, debug using SW/HW tools, champion CI/CD and TDD, and mentor junior engineers. Collaborate across teams to ensure performance, reliability, and secure high-speed data handling for space-based communications.

Lead the development of satellite communications ground systems, managing hardware, software, and systems engineering teams from concept to production.

Design, implement, and operate visualization software for a dynamic satellite and terrestrial network. Build geospatial and graph-based views, backend services and APIs, data delivery mechanisms, playback and event-reconstruction tools, and tools for tracing, filtering, and investigating network state and incidents. Partner with network and systems engineers to optimize performance, security, observability, and resilience.

Lead end-to-end technical programs for satellite communications systems, coordinating multidisciplinary teams (RF, ASIC/FPGA, embedded software, hardware, mechanical, manufacturing). Manage schedules, risks, vendors, prototypes, integration, validation, NPI, production ramp, and executive reporting while ensuring cross-functional alignment of requirements, interfaces, and deliverables.

Develop and own end-to-end, high-fidelity simulation frameworks for large multi-beam phased-array satellite communication systems. Model digital/hybrid beamforming, array performance, RF impairments, satellite geometry, and link budgets. Perform Monte Carlo and corner-case analysis, generate coverage/SINR maps, evaluate architecture tradeoffs, and translate results into antenna, RF, and digital implementation requirements. Collaborate with cross-functional teams and support correlation with hardware measurements and system testing.

Lead verification planning and execution for complex ASIC/SoC digital subsystems. Develop UVM testbenches, reference models, scoreboards, protocol monitors, and assertions. Drive coverage closure, regression health, and verification signoff. Identify corner cases, collaborate across design, systems, DFT, firmware, and physical design, and support emulation, prototyping, and post-silicon debug.
