We are looking for an experienced Telematics Integration Test Engineer to perform joint integration testing and end-to-end (E2E) validation of connected vehicle services within a Telematics Service Provider (TSP) ecosystem.

The ideal candidate will have a strong understanding of connected vehicle architecture and business logic, including interactions between backend microservices, vehicle telematics systems, and mobile applications. The role requires hands-on experience in SQL-based data validation, backend log analysis, API testing, and cross-functional troubleshooting to ensure seamless communication and data consistency across the entire system.

Key Responsibilities

• Perform joint integration and end-to-end (E2E) testing of automotive telematics and connected vehicle services.

• Validate interactions and data consistency between TSP backend microservices, vehicle-side systems (TCU/TCAM and in-vehicle infotainment), and mobile applications (iOS/Android).

• Execute SQL queries independently to verify database records, data integrity, business logic, and state transitions across integrated systems.

• Analyze backend logs using tools such as Kibana, Splunk, and ELK Stack to identify root causes of integration failures, API mismatches, and communication issues.

• Investigate end-to-end data flows, message exchanges, and service orchestration across distributed systems.

• Design, develop, and execute integration test scenarios covering real-world connected vehicle use cases, including remote commands, vehicle status, Over-the-Air (OTA) updates, eCall, and remote diagnostics.

• Perform API testing and validate communication protocols, message payloads, and service responses.

• Verify communication between systems using protocols such as TCP/IP, HTTP/HTTPS, MQTT, and Protobuf.

• Collaborate with backend developers, vehicle integration teams, and mobile application teams to troubleshoot and resolve complex technical issues.

• Lead and participate in joint debugging sessions to identify root causes and drive defects to closure.

• Validate backend business error codes, exception handling, and failure scenarios.

• Prepare test reports, defect documentation, integration test results, and quality assessments to support release readiness.

Required Skills and Qualifications

• Bachelor's or Master's degree in Computer Science, Telecommunications, Electrical Engineering, or a related technical discipline.

• Minimum 3 years of experience in integration testing, system validation, or joint debugging, preferably within the automotive telematics or connected vehicle domain.

• Strong understanding of connected vehicle architecture, particularly TSP, TCU/TCAM, and mobile application interaction flows.

• Hands-on experience with SQL queries and database validation using MySQL, PostgreSQL, Oracle, or similar relational databases.

• Experience analyzing logs and troubleshooting issues across distributed backend systems.

• Good understanding of networking and communication protocols, including TCP/IP, HTTP/HTTPS, and MQTT.

• Experience with API testing tools such as Postman, JMeter, or cURL.

• Familiarity with log monitoring and analysis tools such as Kibana, Splunk, or ELK Stack.

• Ability to trace end-to-end transactions and investigate failures across mobile applications, backend services, and vehicle systems.

• Excellent analytical, troubleshooting, and problem-solving skills.

• Strong written and verbal communication skills in English.

Preferred Qualifications

• Experience working on automotive OEM or Tier-1 supplier projects involving connected vehicle or telematics services.

• Knowledge of T-Box/TCU registration, activation, provisioning, and TSP lifecycle management.

• Familiarity with connected vehicle business processes, backend error codes, and exception-handling mechanisms.

• Basic scripting skills in Python or Shell for log parsing, data preparation, and test automation support.

• Experience working with cloud platforms such as AWS or Azure.

• Understanding of microservices architecture, asynchronous messaging, and distributed system integration.

• Exposure to OTA updates, eCall, remote diagnostics, remote vehicle commands, and vehicle status monitoring.
