Design and build the core real-time systems behind our IoT platform, tackling low-latency, high-reliability challenges in C++.

Your Role

As a Senior C++ Software Engineer on the Core Systems Team, you will architect, implement, and optimize real-time software components that power our next-generation IoT platform. You'll work closely with hardware engineers, algorithm developers, and product managers to push the boundaries of deterministic performance.

Key Responsibilities

• Design and develop high-performance, low-latency C++ applications for embedded Linux and bare-metal systems.
• Implement real-time control loops, data acquisition pipelines, and communication protocols (e.g., UDP, MQTT, CAN bus).
• Perform code reviews, static analysis, and unit/integration testing to ensure reliability and maintainability.
• Optimize memory usage, CPU utilization, and thread synchronization for resource-constrained environments.
• Collaborate with cross-functional teams to define system requirements and architectural decisions.
• Mentor junior engineers and contribute to internal knowledge bases.
• Profile and debug performance bottlenecks using tools like perf, Valgrind, and custom profiling frameworks.
• Participate in on-call rotation for critical production systems (rare).

Our Tech Stack

• Platforms: Embedded Linux (Yocto/Buildroot), RTOS (FreeRTOS, Zephyr)
• Tools: CMake, Git, Jenkins, Docker, Jira, Confluence
• Hardware: ARM Cortex-A/M, x86, custom FPGA interfaces
• Testing: Google Test, CppUnit, automated CI pipelines
• Optional: FPGA programming (VHDL/Verilog), Rust experience is a plus

• 5+ years of professional C++ development experience, with at least 3 years in real-time or embedded systems.
• Deep understanding of modern C++ (C++17 and above), including STL, templates, and RAII principles.
• Strong knowledge of real-time operating systems, concurrency, and synchronization primitives.
• Proficiency in Linux system programming (processes, threads, IPC, signals).
• Experience with low-level hardware interaction (GPIO, SPI, I2C, interrupts).
• Solid grasp of software design patterns, data structures, and algorithms for performance-critical applications.
• Proven ability to debug complex system issues using GDB, crash dumps, and tracing tools.
• Familiarity with version control (Git), continuous integration, and automated testing.
• Educational Background: Bachelor's or Master's degree in Computer Science, Electrical Engineering, or a related field.
• Language Skills: Fluent in English (B2+) and/or German (B1+ is a plus).
• Nice to have: Experience with safety-critical standards (ISO 26262, DO-178C) or industrial protocols (PROFINET, EtherCAT).
• Must be eligible to work in the EU (visa sponsorship available for exceptional candidates).

• Attractive Compensation: Competitive salary with regular performance reviews and bonuses.
• Flexible Work Model: Option for remote work within Germany, with a modern office in Karlsruhe for in-person collaboration.
• Personal Development: Budget for conferences, training, and certifications, plus access to an online learning platform.
• Innovative Tech Stack: Work with cutting-edge technologies in real-time systems, C++17/20, and low-level optimization.
• Team Culture: Regular team events, flat hierarchies, and a supportive environment encouraging knowledge sharing.
• Health & Wellness: Subsidized gym membership, mental health support, and ergonomic workspace setup.
• Relocation Support: Assistance for candidates moving to the Karlsruhe area, including visa and housing support.
• Hardware & Tools: Choose your development machine (Linux/Windows), with dual monitors and latest toolchain.
