Role Summary:

Unistring Tech Solutions Pvt. Ltd. is looking for a Senior Application Engineer with a strong

background in Electronics and Communication Engineering, GNSS systems, digital communication, and C programming. The selected candidate will work closely with the VLSI, embedded software, signal processing, and system engineering teams to support application development, hardware–software integration, system-level testing, troubleshooting, and customer-specific product validation.The role requires hands-on technical involvement, coordination of junior engineers, and ownership of the overall functional performance of the system.

Key Responsibilities:

1. Application Development and C Programming

• Develop, modify, test, and maintain application software using the C programming language.
• Implement algorithms and control logic for embedded, communication, GNSS, and VLSI based systems.
• Debug software using logs, test outputs, hardware observations, and system-level measurements.
• Review C code for functionality, modularity, and compliance with project requirements.

2. GNSS and Communication-System Supporthttps:

• Work with GNSS concepts such as satellite navigation, signal acquisition, tracking, positioning, timing, and receiver operation.
• Support testing and validation of GNSS-related hardware and software modules.
• Understand and work with digital modulation schemes such as: BPSK, QPSK and FSK

3. Collaboration with the VLSI Team

• Work closely with the VLSI design, FPGA, RTL, and verification teams during system development and validation.
• Assist in validating RTL or FPGA functionality from an application and system-level perspective.

4. System-Level Testing and Validation

• Take ownership of overall system-level functionality testing.
• Prepare and execute functional test cases, integration test procedures, and validation checklists.
• Verify end-to-end operation across hardware, firmware, software, communication, and user interface components.
• Validate system inputs, outputs, interfaces, connectivity, control functions, and identify
• functional gaps, reproduce failures, perform preliminary root-cause analysis, and coordinate

issue closure.

5. Team Handling and Technical Coordination

• Guide and coordinate junior application engineers, software engineers, and test engineers for
• Allocate tasks, monitor progress, review technical outputs, and ensure timely completion.
• Conduct technical discussions, code reviews, test-result reviews, and issue-resolution meetings.
• Coordinate activities between VLSI, embedded software, signal-processing, hardware, testing, and field-support teams.

6. Documentation and Reporting

• Prepare and maintain: Software design and interface documents, Test plans and test procedures along with System validation reports
• Document test results, observations, limitations, corrective actions, and closure status.

7. Customer and Field Support

• Participate in customer technical discussions, demonstrations, system integration, and acceptance activities.
• Support installation, configuration, testing, troubleshooting, and demonstration of systems at
• customer locations.

Required Technical Skills:

• Strong knowledge of C programming.
• Good understanding of embedded-software development and debugging.
• Knowledge of GNSS fundamentals, including positioning, timing, signal acquisition, and tracking concepts.
• Understanding of digital communication and modulation schemes, particularly: BPSK, QPSK and FSK
• Knowledge of basic signal-processing concepts such as: Sampling, Filtering Frequency-domain
• analysis, Signal-to-noise ratio and FFT fundamentals
• Familiarity with FPGA-, RTL-, or VLSI-based system development.
• Experience in preparing test cases, validation procedures, and technical reports.

Preferred Skills:

• Experience with FPGA development platforms or VLSI prototype systems.
• Familiarity with C Language ,VHDL or Verilog at an interface-understanding level.
• Knowledge of MATLAB or Python for signal analysis and test automation.
• Experience in defence, aerospace, navigation, communication, radar, or electronic-system projects.
