    GNSS Digital Signal Processing Engineer

    Job Type: Full Time
    Job Location: Athens Barcelona Patras Remote

    Loctio¬†is a deep-tech¬†startup¬†whose mission is to democratize¬†IoT location-based services by catering positioning capabilities to billions of devices¬†constrained by limited processing and power resources.¬†Loctio¬†aims at offering accurate, secure, trusted and ubiquitous low power positioning for both outdoor and indoor challenging environments. This is achieved¬†by¬†means of a breakthrough¬†Cloud/Edge¬†processing technology that combines¬†signals from GNSS satellites (GPS, Galileo,¬†Beidou,…)¬†with LEO satellites and 5G signals.¬†Loctio¬†is backed by venture capital¬†(VC) and by the¬†European Space Agency (ESA)¬†through the¬†Greek¬†Business Incubation Center (BIC).¬†

    Job description:¬†Loctio¬†is seeking¬†an¬†experienced digital signal processing (DSP) engineer to join¬†the¬†team¬†that is¬†currently¬†responsible for the development of¬†the company’s¬†core¬†Cloud/Edge¬†positioning¬†algorithms.¬†The candidate will¬†be working¬†side-by-side¬†with talented and¬†subject-matter experts, developing cutting-edge software algorithms for GNSS, LEO, and 5G signal processing¬†as well as¬†reporting directly to the¬†PM in a¬†horizontally fashioned organogram.

    We offer: A very competitive salary alongside perks and stock options Рall of them adjusted according to the seniority of the candidate and his/her profile-position fit.


    • Develop¬†GNSS signal processing algorithms for¬†ultra-low¬†positioning,¬†combating spoofing attacks,¬†exploiting the use of¬†multi-antennas at the user terminal,¬†providing multi-constellation and multi-frequency positioning,¬†and/or¬†taking advantage of LEO and 5G signals to assist the¬†GNSS positioning engine.
    • Implement the developed algorithms in Matlab/C/C++ for their integration into the cloud/edge positioning platform.
    • Assess key performance indicators and perform statistical analyses to benchmark different¬†algorithm implementations and/or optimizations.


    In 2 weeks

    You will get an overview¬†of¬†the system architecture and¬†Loctio‘s¬†DSP algorithms.

    In 2 months

    You will be familiar with the DSP algorithms and the positioning platform implemented so far.

    From 4 months onward

    You will be contributing with brilliant new DSP algorithms and improvements to the DSP algorithms implemented so far, thus becoming a key member of the team.


    • M.Sc. or Ph.D. in electrical or telecommunications engineering. Other degrees, such as computer science,¬†physics, surveying engineering or geoinformatics can be considered if¬†complemented with¬†adequate¬†experience.
    • At least 2 years of hands-on involvement into GNSS technology¬†at signal processing or receiver level.
    • Solid experience¬†in¬†DSP algorithm design¬†including coding and¬†simulation in Matlab.
    • Knowledge in embedded software development (C/C++ programming, debugging, testing, continuous integration).

    Not mandatory but valued

    • Experience¬†using¬†software-defined¬†radio (SDR) devices such as RTL-SDR or USRP.¬†
    • Familiar¬†with common analog/RF impairments encountered in GNSS¬†or¬†wireless¬†receivers¬†in general.¬†
    • Strong foundation in physical layer functionality for wireless systems in areas such as detection/acquisition, synchronization, parameter estimation & tracking, etc.¬†
    • Experience with¬†version control¬†tools (e.g.¬†Git,¬†SVN,¬†Perforce, etc.)¬†and requirements management tools (e.g.¬†Jira).


    The vacancy could be partially or fully remote depending on the candidate’s profile and experience. Physical presence, when required, can take place at either the company offices in Athens-GR, Patras-GR, or Barcelona-ES.
