Company Summary:


NextNav is a leader in next generation 3D GPS - providing floor-level vertical location to enable a whole new ecosystem of applications and services. NextNav's Pinnacle technology, available in more than 4400 cities and towns across the United States, delivers highly accurate vertical positioning to transform location services, reflect the 3D world around us, and support innovative, new capabilities including supporting first responders to helping to shape the metaverse. NextNav’s TerraPoiNT network delivers accurate, reliable, and resilient positioning, navigation and timing (PNT) services on a terrestrial network to support critical infrastructure and other GPS-reliant systems in the absence or failure of GPS. NextNav started trading on the NASDAQ on October 29, 2021, and are growing rapidly. This is a unique opportunity to join a rapidly growing, future-forward technology that is fundamentally shaping how we experience the world around us.

Position Summary:

This position is for a Senior/Staff Systems Engineer (Timing) working on the development of algorithms for a timing receiver, algorithm optimization using simulations and extensive field data, and working with Software/Firmware teams to implement the algorithms as well as verifying and demonstrating the timing performance on the receiver platform.

Benefits:

  • Medical/Dental/Vision/Ancilliary insurance
  • 401k + 5% safe harbor match
  • 15 PTO days per year, increases by experience tier


Compensation Package:

  • $138k - $186k base
  • Equity awards (vary by position)
  • Year-end bonuses (vary by position)


This role is also eligible for participation in annual cash bonus and equity grants. The actual offer, including the compensation package, is determined based on multiple factors, such as the candidate's skills and experience, and other business considerations.



Education & Experiences:

  • MS or PhD (preferred) in EE/ECE with emphasis in Signal Processing/Communications.
  • 3+ years of experience in design and implementation of advanced signal processing algorithms
  • Solid foundation in probability, statistics, and random processes, estimation & detection, communication theory, signal processing, control theory

This role is also eligible for participation in annual cash bonus and equity grants. The actual offer, including the compensation package, is determined based on multiple factors, such as the candidate's skills and experience, and other business considerations.


Responsibilities:

  • Develop algorithms to estimate time and frequency using the time of arrival from one or more terrestrial radio navigation signals using various signal processing techniques
  • Develop and implement frequency and phase locked loop to control an oscillator based on the time and frequency estimates
  • Perform performance simulations to check for the stability and robustness of the time and frequency estimates
  • Develop and implement key computational/control algorithms for target hardware platforms
  • Support design, implementation, and testing of various algorithms on a receiver
  • Perform timing performance analysis for prototype/product timing receiver such as through analysis of field tests, customer data

Skills

  • Strong analytical and problem-solving ability, math background
  • Good understanding of cellular communication systems such as LTE/5G and satellite PNT systems such as GNSS system, receiver implementation experience is a plus
  • Understanding and optimization of algorithm implementation complexity for target hardware platforms
  • Proficient with algorithm development and performance analysis using Matlab. .
  • Ability to work independently and within a team or across multiple teams (such as hardware, software, test) to deliver prototype/product solution

Desired Skills:

  • Understanding of timing distribution based on ITU timing standards (e.g. ITU-T G.8272, ITU-T G.8272.1), IEEE PTP v1/v2 (including GM, BC, TC), optical fiber
  • Understanding of clock/oscillator types (e.g. OCXO, SuperOCXO, Rb, Cesium) and stratum levels
  • Working experience with lab equipment such as RF signal generator, spectrum analyzer, oscilloscope, time interval counters
  • Knowledge of C programming for algorithm implementation
