Embedded Systems Software Engineer
At Delian, we design and build critical infrastructure for high-impact missions. As we expand our high-performance teams across Athens and London, we’re seeking an Embedded Systems Software Engineer to join us in Athens.
In this role you will
Design and develop low-level embedded software for real-time data acquisition, signal processing, and control on resource-constrained edge hardware.
Build and maintain Board Support Packages (BSPs), device drivers, and hardware abstraction layers for custom and off-the-shelf platforms.
Develop and optimize firmware and system software for embedded Linux, RTOS, and bare-metal environments.
Implement and manage hardware interfaces and communication stacks (UART, SPI, I2C, CAN, Ethernet).
Benchmark and optimize system performance for latency, power consumption, and thermal constraints.
Develop and maintain cross-compilation toolchains, build systems, and OTA update mechanisms (e.g. Yocto).
Support bring-up, debugging, and validation of new hardware platforms in lab and field environments.
Collaborate with hardware and systems teams to ensure tight integration between software and electronics.
Must have experience
Degree in engineering, computer science, or related field.
Experience in embedded software development on real hardware.
Practical experience deploying embedded systems in real-world environments, iterating and improving them.
Strong understanding of RTOS, embedded Linux, and bare-metal systems.
Proficiency in C/C++ (Python for tooling is a plus).
Experience with low-level debugging tools (JTAG, oscilloscopes, logic analyzers).
Hands-on experience with edge platforms (e.g., Raspberry Pi, BeagleBone, Nvidia Jetson).
Strong understanding of embedded communication protocols (UART, SPI, I2C, CAN, Ethernet).
Experience with build systems and CI/CD pipelines for validating embedded software.
Experience integrating and validating hardware peripherals and sensors at driver level.
Experience with RF electronics and signal processing.
Nice to have
Experience with real-time scheduling, deterministic systems, or TSN.
Background in safety-critical or defense systems.
Familiarity with embedded security hardening and secure boot.
Experience with power optimization and thermal management on edge devices.
