Software Developer - Bangalore

Greetings from Vidpro Consultancy.

We are hiring for Software Developer/Engineer for one of our Aerospace and defense.

Software Developer / Engineer.

Role summary

Convert approved algorithms from MATLAB or Python into embedded C/C++, build the operational

software around them, port it to a real-time target running VxWorks, and integrate and test it on the

target hardware.

Key responsibilities

• Convert algorithms from MATLAB or Python into optimised, embedded-grade C/C++ code.

• Design and build the operational software framework: tasks, data flow, interfaces and error

handling.

• Port and deploy the software on target hardware using VxWorks and its IDE.

• Develop and integrate Ethernet, MIL-STD-1553 and PCIe interfaces as defined in the interface

specifications.

• Integrate with the existing system software on the target. • Profile and optimise for real-time performance, and produce benchmark results. • Re-run the algorithm test cases on the software modules and prove the outputs match the

prototype.

• Support integration and hardware-in-the-loop (HIL) testing.

• Verify output data timing, size and duration against the acceptance criteria.

• Maintain commented, documented source code and provide design inputs for reviews.

Qualification

• B.E./B.Tech or M.E./M.Tech in CSE, ECE or EEE.
• • Minimum 3 years of embedded software development in C and C++. Must-have skills for every candidate Area What you must be able to do C programming Data types, pointers, arrays, structures and unions, bit manipulation, function pointers, memory layout, and static and dynamic memory

Embedded C Writing code for a target board: memory-mapped registers, interrupts, timers, volatile and const usage, fixed-size data structures, and code without dynamic memory allocation

C++ programming Classes, inheritance, templates, STL containers, and modern C++ (C++11/14) features that are suitable for embedded use

RTOS, mainly VxWorks Tasks and priorities, scheduling, semaphores and mutexes, message queues, timers, interrupt service routines, and priority inversion. Hands-on VxWorks application development with Wind River Workbench

Ethernet interface Socket programming with UDP and TCP, packing and unpacking binary messages, byte order handling, and network debugging

MIL-STD-1553 interface Bus controller, remote terminal and bus monitor roles, message formats, sub-addresses, and using a 1553 interface card and its driver API

Area What you must be able to do

PCIe interface Understanding of PCIe devices and drivers, device enumeration, memory- mapped I/O, and communicating with PCIe-based interface cards

Embedded hardware Hands-on work with edge devices or avionics single-board computers

(SBCs): board bring-up support, boot flow, BSP usage, and cross-compilation

Algorithm conversion Convert MATLAB or Python algorithms to C/C++, including matrix

operations and numerical code, and prove the output matches the original

Multithreading Design thread-safe code, and avoid race conditions and deadlocks

Debugging and optimisation Use debuggers and profilers on a target board, and find timing, memory and performance faults

Code quality Follow a coding standard such as MISRA C/C++, write unit tests, and use static analysis tools

Working independently Write code without internet search or AI tools, using your own knowledge and offline documentation

Tech stack

• Languages: C, Embedded C and C++.
• RTOS and IDE: VxWorks with Wind River Workbench. Other RTOS experience is also considered.
• Interfaces: Ethernet (UDP/TCP), MIL-STD-1553, PCIe and serial (RS-232/RS-422).
• Hardware: Avionics SBCs and edge devices, for example PowerPC, ARM or x86 based boards.
• Libraries: Eigen or another linear algebra library.
• Testing: GoogleTest or similar, gcov for coverage, and HIL test setups.
• Static analysis: Cppcheck, Coverity, PC-lint, LDRA or Polyspace.
• Build and version control: Git, Make/CMake, and cross-compilation toolchains. Good to have
• Python or MATLAB knowledge, which is an added advantage for algorithm conversion and test

scripting.

Experience with MATLAB Coder or similar code generation
