DSP Software Engineer

We're looking for DSP Software Engineers to join our team. You'll work alongside an exceptional team of engineers, developing the embedded and DSP software that brings our silicon to life — from real-time wireless signal processing to the low-level APIs that the rest of the stack runs on.

We're hiring across experience levels, from engineers early in their career to senior contributors ready to own complex software subsystems.

Responsibilities:

• Develop embedded and/or DSP software for wireless communication systems — including modem baseband processing, signal chain control, calibration, and real-time algorithms.

• Implement and optimize DSP algorithms (filtering, synchronization, modulation/demodulation, channel estimation) on embedded targets and DSP cores.

• Develop low-level SoC software: drivers, hardware abstraction layers, bring-up code, and APIs exposing on-chip peripherals and accelerators to higher software layers.

• Work close to the hardware — interfacing with on-chip interconnects, DMA, high-speed interfaces, and RF transceiver control paths.

• Optimize for real-time constraints, performance, memory footprint, and power across embedded CPU, DSP, and accelerator targets.

• SoC bring-up and silicon validation — from first power-on, through driver and firmware bring-up, to stable system operation.

• Collaborate with algorithm, hardware, and architecture teams to translate algorithmic intent into efficient embedded implementations, and to shape hardware/software trade-offs early.

• Contribute to test infrastructure, automation, and continuous integration for embedded software.

Skills & Experience:

• Background in embedded software, DSP software, or low-level systems programming — from engineers with strong fundamentals and relevant project work, up to senior contributors with multiple silicon programs behind them.

• Strong proficiency in C/C++/Rust, with comfort working close to the hardware.

• Solid understanding of embedded systems concepts: real-time constraints, interrupts, DMA, memory hierarchies, and hardware/software interfaces.

• Familiarity with at least one of: DSP algorithm implementation, wireless modem software, or low-level driver / HAL development.

• Experience with bare-metal or RTOS environments (FreeRTOS, Zephyr, or equivalents).

• Debug skills across software and hardware boundaries — comfortable with logic analyzers, scopes, JTAG, and reading schematics when needed.

• Eagerness to learn, take ownership, and grow with the team.

• English proficiency at B1 level or higher.

Nice to Have:

• Experience with wireless communication systems (SDR, modem baseband, Wi-Fi, 5G/LTE, or proprietary radios).

• Hands-on experience with DSP cores (Cadence Tensilica, CEVA, ARM Helium, or similar) and DSP-specific optimization.

• Experience with fixed-point arithmetic and porting algorithms from MATLAB / Python references to embedded targets.

• Experience with high-speed interface drivers (JESD204B/C, MIPI CSI/DSI, PCIe).

• Experience bringing up custom silicon from first power-on to stable operation.

• Boot ROM development.

• Knowledge of cryptography, secure boot, or hardware-level security.

• Experience in defense or dual-use systems.

• Open-source contributions, embedded projects, or relevant portfolios (especially for early-career candidates).
