Location – Bangalore
Experience – 5-10 years
Work mode- Onsite, immediate
Notice period – 15 days max
Your Responsibilities
Development and maintenance of embedded software in C/C++ for microcontroller-
based systems.
Programming and configuration of STM32 microcontrollers (Cortex-M0+, M4, M33).
Implementation of device drivers, peripheral interfaces, and communication protocols
(UART, SPI, I²C, etc.).
Adaptation and optimization of existing product software.
Software integration and testing on target hardware.
Conducting Unit-Tests and Code Reviews.
Driving and contributing to the test strategy.
Design and maintenance of the development ecosystem and CI/CD pipelines using
GitLab/Jenkins.
Setup, maintenance, and continuous improvement of embedded toolchains (compilers,
linkers, debuggers, build systems).
Optimization and integration of embedded IDEs (e.g., JetBrains CLion, VS Code) with
appropriate plugins.
Evaluation and documentation of tools, and creation of development guidelines.
Collaboration with cross-functional teams (mechanics, electronics, testing, hardware).
Future outlook: Participation in setting up a Linux-based toolchain and training
colleagues.
Your Profile
Degree in Computer Science, Electrical Engineering, or equivalent qualification.
Strong proficiency in C and C++, preferably in embedded software development.
Experience in STM32 microcontroller families (especially Cortex-M0+, M4, M33).
Experience with embedded development toolchains, IDEs (CLion, VS Code), and CI/CD
systems.
Familiarity with Unit-Test frameworks (e.g., Google Test).
Solid understanding of schematics, technical datasheets, and reference manuals.
Strong proficiency in Linux OS.
Open-minded, structured, independent working style and strong team player.
Good communication skills in English (German is a plus).
Soft Skills
Open-minded, willing to learn, and forward-looking attitude.
Curious, questioning the status quo, and proactive in sharing ideas.
Analytical thinking and structured approach.
Team-oriented with a security-focused and test-driven development mindset.
Motivation & Role Impact
You will contribute to the core embedded systems framework by implementing the
complete hardware abstraction layer. Your work will enable application developers to
access microcontroller features more efficiently and will support a highly modular and
reusable software environment across product lines.
