Senior Embedded Software Engineer – TSP Agent (Embedded Linux / C++20) IRC307612

Description We are looking for a Senior Embedded Software Engineer to develop the Telematics Service Platform (TSP) agent running on the T-Box application processor under Embedded Linux. The TSP agent is responsible for connected-vehicle services, secure cloud connectivity and communication between backend systems and vehicle functions. It terminates cloud connections over MQTT using Protocol Buffers and translates remote commands into vehicle signals through D-Bus interfaces. The role involves developing a modern C++20 application supporting more than 20 remote services, device lifecycle management, vehicle-signal integration and reliable communication with the MCU-based Digital Key agent. The ideal candidate has strong C++ and Embedded Linux experience, with a background in connected devices, automotive telematics or distributed software systems. Requirements Required Skills and Experience

• Strong professional experience in modern C++, preferably C++17 or C++20.
• Hands-on experience developing applications on Embedded Linux.
• Strong understanding of asynchronous programming, concurrency and event-driven architectures.
• Experience with network communication protocols and resilient service design.
• Practical experience with MQTT and Protocol Buffers or equivalent binary serialisation technologies.
• Experience with D-Bus, preferably GDBus or GLib/GIO.
• Strong knowledge of software design, type-safe interfaces and error handling.
• Experience with TLS, certificates and secure device-to-cloud communication.
• Familiarity with Linux debugging, automated testing and software build systems.

Preferred Qualifications

• Experience in automotive telematics, connected vehicles or embedded connectivity platforms.
• Knowledge of CAN signals, vehicle data models and automotive service interfaces.
• Experience with advanced C++ templates and compile-time type checking.
• Familiarity with mTLS bootstrap, CSR generation and certificate renewal.
• Experience with serial or IPC protocols involving acknowledgements, retries, fragmentation and heartbeats.
• Knowledge of systemd, CMake, cross-compilation and Linux service development.
• Familiarity with automotive cybersecurity and vehicle integration testing.

Job responsibilities Connected Vehicle Services

• Design and implement a common software interface for 20+ remote vehicle services.
• Develop service handlers for remote locking, windows, climate control, charging and V2L scheduling, vehicle status, location, sentry mode, child-presence detection, geo/time/speed fencing, in-vehicle messaging and driver profiles.
• Implement per-service protocol version negotiation and backend-driven service activation.
• Translate backend commands into validated vehicle operations and return vehicle responses to the cloud.
• Implement service-level error handling, timeout management and backward compatibility.

Cloud Connectivity and Messaging

• Develop an MQTT connection state machine covering connection, authentication, disconnection, reconnection and recovery.
• Integrate Protocol Buffers for message serialisation and deserialisation.
• Implement asynchronous message processing, queue management and backpressure.
• Support secure cloud connectivity using mutual TLS (mTLS).
• Handle retries, timeouts, connectivity loss and delayed or duplicate messages.
• Implement logging, diagnostics and production troubleshooting support.

Device Lifecycle and Security

• Implement secure device bootstrap registration and onboarding.
• Develop on-device CSR generation and service-certificate renewal.
• Integrate backend provisioning and configuration management.
• Manage device identity, certificate lifecycle and recovery from provisioning failures.
• Apply secure coding practices and ensure appropriate protection of sensitive credentials.

Vehicle Abstraction and Signal Integration

• Design and implement the GDBus-based vehicle abstraction layer.
• Integrate several hundred CAN signals using a compile-time-checked C++ template-based binding pattern.
• Develop type-safe mappings between vehicle signals, D-Bus interfaces and service data models.
• Implement signal subscriptions, command dispatch and response handling.
• Handle invalid, unavailable or stale signals and communication failures.

MCU Communication and Flow Control

• Implement the bidirectional communication layer between the TSP agent and the MCU Digital Key agent.
• Enforce single-message-in-flight serialisation in both directions.
• Implement ACK/NACK handling, retries, timeouts and fallback mechanisms.
• Support connection heartbeats, message fragmentation and reassembly.
• Implement queue supervision, bounded resource usage and recovery from interrupted transfers or MCU resets.

Testing and Quality

• Develop unit tests, integration tests and fault-injection scenarios.
• Debug issues across Linux services, networking, D-Bus, vehicle interfaces and MCU communication.
• Participate in architecture reviews, code reviews and continuous integration activities.
• Collaborate with cloud, platform, vehicle integration and cybersecurity teams.
