The Onboard Platforms team is an embedded software team responsible for the development and maintenance of the OS, software, and firmware for the compute platform powering our L1/L2/L3 autonomous vehicle compute clusters. The RTOS and applications team is specifically responsible for creating and maintaining our safety monitors to uphold our functional safety. This team leads the hands-on enablement of Jacinto/TDA4 safety diagnostics.
This role specifically will be responsible for integrating safety diagnostics on Texas Instruments TDA4 chip.
What you ’ ll do:
- Translate TI safety manuals, SDL APIs, and TRM details into working firmware so runtime health monitors can interrogate power, clock, ECC, watchdog, and other core-health features with confidence.
- Stand up TI SDL diagnostic flows (ECC, register-readback, LBIST, watchdog, power/clock monitors) on both R5 and A72 domains, validating them directly against hardware.
- Assist in the creation of implementable test and validation plans.
- Build pub/sub style diagnostic bridges so MCU firmware publishes platform identifiers and safety telemetry that application processors can subscribe to.
- Author low-level HALs, TI-SCI clients, and RPMsg transports that expose diagnostic registers safely to higher-level services while respecting functional-safety partitioning.
- Create automated bench experiments that prove parity/ECC injections, power-domain asserts, and watchdog trips behave per TDA4 safety manuals, then turn those learnings into reusable test suites.
- Partner with functional-safety stakeholders to document assumptions of use, trace TI safety mechanisms into system safety cases, and close hardware-facing gaps the software team cannot address alone.
- Mentor platform engineers on how to debug TI diagnostics with Trace32, TI UART consoles, and on-target scripting so knowledge spreads beyond a single expert.
What you'll need to succeed:
- Demonstrated experience bringing up TI Jacinto (TDA4/TDA4VH/TDA4AP)or similar automotive SoCs at the register level, including TRM-guided peripheral init.
- Deep familiarity with TI SDL/SDK diagnostic components (ECC, VIM, PBIST/LBIST, watchdog, power/clock) and the ability to prove them in hardware.
- Comfort writing production-quality C++for FreeRTOS/SafeRTOS R5 firmware.
- Functional safety mindset (ISO 26262):able to interpret safety manuals, lock down assumptions of use, and supply evidence for certification reviews.
- Fluent with bench tools (Trace32, serial consoles, TI scripts) and confident debugging directly on ECU hardware.
- The discipline to land diagnostics with unit/integration tests.
Nice to have (optional):
- Familiarity with Bazel-based builds
- Background collaborating with OEM functional-safety teams or delivering diagnostics evidence into safety cases.
