Job description

Description : Avionics Embedded Engineer.

Exp : 2-4 yrs.

Loc : Bengaluru.

Notice : 30 days.

Key skills :

Embedded C / C++ on MCU / SoC targets with RTOS (VxWorks / RTEMS / FreeRTOS) and bare-metal application design for hard real-time behaviors.
Strong in defining application entities directly from ICDs; precise parsing, validation, versioning, and change tracking of ICD-driven interfaces.
Data handling : raw-to-engineering unit conversions, scaling, calibration tables, endianness handling, fixed-point arithmetic, and overflow / precision controls.
Memory architecture : static-only allocation, linker script awareness, partitioning between read-only / read-write, placement across SRAM / DDR, cache coherency, and alignment.
Concurrency and performance : multithreading / tasking, priority / timing analysis, IPC (queues, mailboxes, shared memory), DMA setup and tuning, ISR design, and lock-free patterns where applicable.
Drivers and buses : UART / SPI / I2C / CAN / Ethernet; familiarity with ARINC 429 / 664 and MIL-STD-1553 is beneficial.
Quality : MISRA C / C++, static analysis basics, unit testing on target, lab instrumentation (JTAG / GDB, oscilloscope, logic analyzer), and rigorous documentation.

Key responsibilities :

Derive software components from ICDs and requirements; define tasks, states, buffers, and message schemas; implement deterministic modules in C / C++ for RTOS / bare-metal targets.

Implement raw-to-engineering conversion pipelines, lookup / calibration, sanity checks, and error budgets; ensure numerical stability and deterministic timing.

Own memory plans with static allocation only; segment code / data thoughtfully across ROM / RAM, SRAM / DDR; manage cache, MPU / MMU regions, and DMA-safe buffers.

Develop and optimize peripheral drivers and DMA paths; implement IPC, health monitoring, watchdogs, and robust error handling / fault containment.

Perform on-target bring-up, profiling, and debugging; validate latency / jitter, throughput, and memory footprints; produce clear design notes, test procedures, and change logs.

Collaborate with systems and hardware teams to maintain ICD alignment and support bench / SIL / HIL testing; address defects with traceable fixes.

Experience required :

2 to 4 years in embedded software development with hands?on real?time programming and on?target debugging in regulated or safety?critical domains (avionics, automotive, medical, rail).

Hands-on experience reading and implementing against ICDs, setting up DMA / IPC, and crafting static-only memory strategies in production firmware.

Nice to have :

Exposure to avionics or radar systems, ARINC 429 / 664 or MIL-STD-1553, timing partitioning (e.g., ARINC 653 style), and basic awareness of DO-178C processes.

NP : 30DAYS.
