About the Job

Requirements

  • A master's degree or higher in aerospace, electrical, or mechanical engineering, physics, or a related field is required.
  • At least 2 years of experience in navigation, estimation, or sensor engineering for spacecraft is required.
  • A strong grasp of estimation theory and hands-on experience implementing filters for real-time systems are required.
  • Hands-on experience with navigation hardware in a laboratory is required.
  • Experience using Python, Julia, C, C++, or Rust for algorithm development, implementation, hardware testing, and simulation is required.

Responsibilities

  • Own the navigation and sensing chain that determines spacecraft position and orientation, from physical sensor hardware through estimation algorithms and flight software.
  • Act as the GNC point of contact for Avionics, flight software, and Test teams.
  • Design, implement, and verify onboard orbit and attitude determination estimation algorithms, including EKF, MEKF, UKF, batch estimators, and sensor fusion.
  • Develop high-altitude GNSS navigation capability for MEO and GEO, including sidelobe and weak-signal tracking, receiver selection, and onboard orbit filtering.
  • Improve measurement and system timing accuracy from sensor output to GNC ingestion to ensure low-latency, low-jitter navigation.
  • Develop and run GNC sensor calibration on the ground and on orbit.
  • Select, specify, and integrate navigation sensors, including GNSS receivers, IMUs, magnetometers, and star trackers, in fault-tolerant architectures.
  • Build sensor models and estimation components in the simulation framework and bring algorithms from prototype into production flight software.
  • Support on-orbit commissioning and navigation performance analysis during mission operations.
  • Define pass/fail performance criteria for GNC hardware during acceptance testing and support investigations of out-of-spec hardware.
  • Recruit, interview, and mentor engineers.
  • Design and characterize the GNSS receiver software driver, establish testing to validate GNSS performance and link budgets as a function of altitude, and feed findings into hardware and onboard filter design.
  • Support multiple launches of the stacked configuration and serve as the GNC point of contact for operations.

Desired Qualifications

  • Experience with early-stage spacecraft conceptual design or clean-sheet design work.
  • Previous experience with high-altitude or cislunar GNSS architectures.
  • Knowledge of GNSS link budgets and antenna pattern modeling.
  • Experience with optics, including star trackers, cameras, and optical navigation.
  • Ability to characterize inertial sensors through Allan variance and PSD analysis to inform simulation and flight software development.
  • Experience with magnetometer calibration and bias compensation, including design and operation of a Helmholtz cage and zero-gauss chamber.
  • Hands-on experience with GNSS simulators, attenuators, LNAs, and spectrum analyzers.
  • Experience with vehicle-level polarity and run-for-record testing.
  • Knowledge of basic power electronics, serial protocols, and Ethernet.
  • Knowledge of avionics radiation basics, including transient and dose effects, how they manifest, and hardware- and software-layer FDIR strategies to mitigate these behaviors.
  • Exposure to environmental testing, including SMC-S-016 and/or HALT/HASS, to facilitate root-cause investigations during GNC component acceptance and qualification testing.

About the Company

K2 Space

Provides cost-effective, high-capability satellite buses

K2 Space provides cost-effective, high-capability satellite buses—the main structure and systems of a satellite excluding the payload. Buses include core subsystems such as power, attitude control, propulsion, thermal management, and communications, and are modular for customers to add their own payloads, enabling large satellites at a lower cost. The company focuses on the bus to decouple payload costs from spacecraft, leveraging an experienced team from SpaceX and Blue Origin to offer affordable, scalable platforms for commercial, scientific, and defense missions. Its goal is to unlock ambitious space missions by making high-capability satellites affordable and expanding opportunities in space exploration and development.
