Position Summary
A Senior Embedded Software Developer position is available for the development and modernization of the GNSS receiver functional software, focusing on positioning engines, data fusion logic, and core navigation algorithms. This role targets the upper layer of the receiver firmware — bridging algorithmic design and embedded implementation. The position requires strong experience in modern C++ development, cross-platform build systems, and model-based architecture to ensure reliable, maintainable, and scalable software across multiple receiver generations.

The ideal candidate combines a solid understanding of GNSS principles with expertise in designing modular, testable, and high-performance software components that integrate tightly with correction services (RTK, PPP, CSSR) and sensor fusion subsystems.

Core

Job Duties

Design, develop, and maintain high-level embedded software modules within GNSS receiver firmware, including positioning engines, navigation filters, and data fusion logic.

Refactor and modernize existing legacy codebases into modular, maintainable, and testable architectures.

Collaborate with algorithm developers to translate mathematical models into efficient and robust C++ implementations.

Integrate GNSS correction services (RTK, PPP, CSSR) and ensure consistent data flow between the receiver and correction sources.

Implement unit tests, integration tests, and performance validation for critical firmware components.

Optimize resource usage, reliability, and runtime performance across diverse hardware targets and operating systems.

Participate in architectural reviews, code reviews, and documentation processes to ensure high engineering standards.

Develop advanced debugging tools for diagnosing issues, post-processing logs, and simulating positioning scenarios.

Port code across different firmware versions and products, ensuring compatibility and performance.

Collaborate with hardware teams to support new hardware development and integration.

Conduct field testing, debugging, and provide ongoing support for deployed products.

Participate in CI/CD workflows (Team City, Bitbucket/Git Hub, Jira) for continuous integration and deployment.

Education & Experience

Master’s degree in Electrical Engineering, Computer Science, or related field.

5+ years of industrial experience developing large-scale applications in C++ (including C++11/14/17) and CMake.

Experience with embedded software and real-time operating systems (RTEMS, FreeRTOS, QNX).

Proficiency with version control systems (Git, Mercurial, SVN), CI/CD pipelines, code quality, and refactoring.

Experience developing multi-threaded applications.

Good knowledge of Python for scripting, automation, and testing.

Experience with Team City or similar CI/CD tools.

Experience with Java for integration tasks is a plus.
