About the job
About Logos Space
Logos Space is building a proliferated Low Earth Orbit (pLEO) constellation to deliver high-performance connectivity for enterprise and government clients worldwide. The Navigation team leads the development of software and infrastructure for spacecraft timing, astrodynamics, orbit determination, and other navigation workflows that support both flight and ground systems.
Role Overview
The Spacecraft Timing System Engineer will join the Navigation team to design, implement, and validate timing systems that enable nanosecond-class onboard accuracy. This role focuses on creating reliable onboard time, improving calibration and observability, and providing dependable timing interfaces for flight and payload systems. The work spans timing and synchronization, FPGA and embedded systems, digital hardware, calibration, and validation.
Depending on experience, the engineer will contribute to or independently manage parts of the timing stack, such as timing measurement and timestamping, clock control and steering, timing distribution, monitoring and telemetry, calibration workflows, and validation automation infrastructure. Success in this position requires the ability to turn partial requirements into actionable software and to collaborate across disciplines.
Key Responsibilities
- Develop and maintain FPGA/RTL, embedded logic, and supporting software for spacecraft timing and synchronization.
- Design and implement timing system features, including measurement, timestamping, clock control, timing distribution, calibration, telemetry, and monitoring.
- Establish and implement hardware/software interfaces: registers, configurations, telemetry, fault and status signaling, and testing hooks.
- Work with electrical, embedded, GNSS, signal processing, flight software, and integration engineers on timing-system architecture, requirements, partitioning, and trade studies.
- Build simulation, testbench, replay, lab validation, and automation infrastructure to verify correctness, stability, and timing performance.
- Characterize timing performance metrics such as accuracy, stability, jitter, phase alignment, latency, deterministic behavior, holdover, reacquisition, and calibration drift.
Location
This position is based in Mountain View or San Diego.
