Embedded Systems Engineer — Rust

Full-time · Türkiye

We design automotive diagnostics and telematics hardware that runs in-vehicle, 24/7, for years at a time. We are looking for an engineer to own the Rust side of a C + Rust hybrid firmware running on ESP32-S3 and STM32H7/H5 platforms: messaging layer, telemetry resilience, FFI boundaries, and hardware-near components. This is a production engineering role, not academic R&D. Code correctness, readability, and predictability are non-negotiable.

Responsibilities

  • Write production-grade Rust components on ESP-IDF v5.x, managing the no_std / std boundary
  • Standardize memory ownership, null-check discipline, and unsafe block justification across C ↔ Rust FFI boundaries
  • FreeRTOS task hygiene: stack sizing, core pinning, priority scheme
  • Telemetry resilience: persistent queue, WiFi/LTE handover, idempotent retries, ordered delivery
  • Build layers that process data from CAN FD / J1939 / OBD-II / DoIP buses
  • Design cloud messaging integration (e.g. NATS JetStream, binary frames, mTLS) for large-scale fleet deployment
  • Write unit / property / fuzz tests and integrate them into CI; enforce panic strategy and error-propagation rules
  • Contribute technically to design and code reviews

Requirements

  • Must-have
  • 3+ years of production embedded experience (ARM Cortex-M and/or ESP32 class)
  • Production-level Rust experience — correct use of unsafe, ownership/borrow model, no_std environments
  • Strong C interop (FFI, extern "C", memory management)
  • RTOS experience (FreeRTOS preferred), concurrency at task and interrupt level
  • Hardware-near debugging: oscilloscope, logic analyzer, JTAG/SWD
  • Ability to read and write English technical documentation
  • Preferred
  • Automotive buses: CAN FD, J1939, OBD-II, UDS, DoIP
  • STM32H7/H5 family, TrustZone, secure flash / encryption
  • LTE / AT command modem integration, lwIP, network resilience
  • ESP-IDF internals, partition/NVS management
  • Signal processing / high-speed ADC data acquisition
  • Awareness of automotive safety/quality standards (ISO 26262, AUTOSAR fundamentals)
  • How to Apply
  • Send your CV and, if available, GitHub or sample embedded projects via the contact provided in the listing. info@xentron.com
