Santa Clara Valley (Cupertino), California, United States
Software and Services


Posted: Nov 16, 2018
Weekly Hours: 40
Role Number: 200009156
As an Estimation Scientist pursuing special projects within the Location Services team, you will be part of an elite group investigating new technologies and how they can transform the lives of our users. We nurture new ideas from prototype to production, helping to establish hardware requirements and system design, conduct developmental testing, write production software, and track our results relative to physical and theoretical limits. Shape the next generation of location-aware mobile experiences by working on state-of-the-art technologies to seamlessly integrate people’s digital and physical lives. If you're passionate about building technology that will make a difference, we may be the team for you.

Key Qualifications

  • Strong theoretical and practical understanding of estimation, especially as it applies to device location (e.g. Kalman filter, particle filter)
  • Strong software developer with high proficiency in C or C++
  • Good understanding of RF and location signal processing techniques, e.g. ranging, TOA, RTT, PDOA, and TDOA
  • Ability to prototype systems for technology evaluation, algorithm development, and error modeling
  • Experience with data analysis and error modeling
  • Good collaboration skills
  • Knowledge of software design paradigms and software development best practices
  • Knows how to debug complex systems
  • Strong creative problem solving skills
  • A passion for developing new technologies
  • Understanding of radar a plus
  • iOS, OS X, application, and/or unix system development a plus


Join a team which designs, implements, and powers brand new technologies and services on the world's fastest-growing mobile development platform. We are looking for a highly-motivated and creative estimation scientist with an understanding of RF-based location technologies and related fields (RF ranging and angle-of-arrival techniques, estimation theory, proximity detection, GNSS, error modeling). Develop estimation strategies and software to investigate new technologies, fuse with existing capabilities, and enable new classes of capabilities and user experience. Invent and design systems to solve interesting problems in RF ranging, angle-of-arrival, GNSS, WiFi/Cell, indoor positioning, iBeacon, location-based reminders, inertial sensor fusion, dead reckoning, crowd-sourced analytics, and other location-related technologies.

Education & Experience

Minimum requirements: MS or PhD in relevant location or estimation field (angle-of-arrival, WiFi, GPS/GNSS, Bayesian estimation, Computer Science, etc, or related field)

Additional Requirements

  • Interested in creating new technologies and solving the algorithmic challenges that come with it.
  • Desire to be exposed to all aspects of development; prototyping, planning, designing, productizing, launching, and scaling.
  • Thrive in a collaborative environment and communicate effectively.
  • Obsessively passionate and inquisitive, and seek to solve everyday problems in innovative ways.
  • Laser-focused on the smallest details that are meaningful to our customers.
