Location: Hybrid: Remote/ Cluj/ Sibiu

At Bringsense Technologies, we’re building a dedicated engineering team focused on secure embedded firmware for next-generation automotive and industrial platforms.

You’ll work close to the hardware, developing software that protects devices from the very first instruction executed after power-up.

If you enjoy understanding how systems really work—not just using APIs—you’ll feel at home here.

Whether you already have experience in embedded security or you’re an experienced Embedded C developer eager to grow into this field, we’d love to talk.

What you will work on:

As part of our engineering team, you’ll contribute to the development of low-level embedded software used in secure platforms for leading semiconductor companies and global automotive OEMs.

Depending on the project, you may work on:

• Embedded firmware development in C
• Secure boot and firmware update mechanisms
• Hardware Security Engine (HSE/HSM) integration
• Bootloaders and startup code
• RTOS-based platform software
• Device drivers and low-level platform components
• Memory protection and system isolation
• Cryptographic service integration
• Embedded debugging and bring-up
• Performance optimization for resource-constrained systems
• Security and reliability improvements across the platform

What we are looking for

The most important requirement is strong Embedded C development experience and the willingness to understand systems at a low level.

You should be comfortable with topics such as:

• Embedded C programming
• Microcontroller architecture
• Memory layout and linker scripts
• Startup code and boot process
• Interrupts and exception handling
• Debugging with JTAG/SWD
• Build systems (Make/CMake)
• RTOS concepts (tasks, scheduling, synchronization)
• Root cause analysis of complex software issues

Security experience is a plus - not a requirement

You don’t need to be a security expert from day one.

If you’ve been exposed to any of the following, that’s great:

• Secure Boot
• Hardware Root of Trust
• Cryptographic concepts (AES, SHA, RSA, ECC)
• HSM / HSE
• AUTOSAR Crypto Stack (Crypto, CSM, KeyM)
• Secure firmware updates
• Authentication and integrity verification
• Secure coding practices

If not, you’ll have the opportunity to learn these technologies while working alongside experienced engineers.

Nice to have

• ARM Cortex-M or Cortex-A
• Embedded Linux
• Bootloaders
• AUTOSAR
• Functional Safety (ISO 26262)
• Static analysis tools
• CI/CD for embedded software
• Embedded security concepts

What makes someone successful here

We’re looking for engineers who:

• enjoy understanding how software interacts with hardware
• like debugging difficult problems
• take ownership of their work
• write clean, maintainable code
• enjoy continuously learning new technologies
• are curious about embedded security and modern platform architectures

You’ll work on projects involving some of the most advanced embedded security technologies used in today’s automotive industry, including secure firmware, hardware security, cryptography integration and trusted execution environments.

Looking forward to getting in contact with you!
