Firmware Engineer (f/m/d) for Embedded / Automotive / ASIP RISC‑V

Job Title

Firmware Engineer (f/m/d) for Embedded / Automotive / ASIP RISC‑V

Role Summary

Design, implement, and validate firmware for Application-Specific Instruction Processors (ASIP) based on RISC‑V for automotive and industrial sensor signal conditioning, actuator control and communication interfaces. Work within cross-functional teams including system architects, product definition, and hardware engineering to define firmware requirements and architectures.

Deliver production-quality, safety-relevant embedded firmware and support toolchains, simulation environments, and debug workflows for resource-constrained, real-time systems.

Experience Level

Mid-level. The posting does not specify required years of experience.

Responsibilities

Primary responsibilities for the role include:

• Collaborate with system architects, product definition, and hardware development teams to capture requirements and design constraints.
• Contribute to the definition, customization, and optimization of ASIP (RISC‑V-based) architectures for target applications.
• Design and implement firmware for deeply embedded application-specific microcontrollers and DSPs (bare-metal environments).
• Define and refine firmware architecture and requirements; establish coding standards and interfaces.
• Develop and execute unit tests, integration tests, and validation strategies; maintain validation artifacts.
• Establish and maintain toolchains, simulators/emulators, and debug workflows to support development and verification.
• Support performance analysis and optimization in constrained real-time environments.
• Ensure implementation complies with functional safety standards such as ISO 26262 and follow ASPICE-relevant processes.

Requirements

Key technical skills and professional requirements.

Must-have:

• Strong expertise in embedded C programming for bare-metal environments and assembler.
• Proficiency with embedded development tools: compilers, debuggers, linkers, and static analysis/testing tools.
• Experience with simulators, emulators, and establishing toolchains and debug workflows.
• Solid understanding of memory-constrained and real-time systems and low-level hardware interaction (register-level programming).
• Familiarity with CPU architecture principles and performance optimization.
• Experience with signal processing basics (e.g., FIR/IIR filters, ADC data handling).
• Experience with Python or similar scripting languages for test automation and tooling.
• Good understanding of ASPICE and ISO 26262 software development processes.
• Professional working proficiency in English (written and spoken).

Nice-to-have:

• Prior experience with ASIP or RISC‑V-based microcontroller/DSP firmware projects.
• Experience in automotive or industrial sensor/actuator domains.

Education Requirements

Bachelor’s or Master’s degree in Computer Engineering, Electrical Engineering, Computer Science, or a related technical field.
