About the Job

Requirements

  • Background in embedded software, DSP software, or low-level systems programming, ranging from strong fundamentals and relevant project work to experience across multiple silicon programs for senior contributors.
  • Strong proficiency in C, C++, or Rust, with comfort working close to the hardware.
  • Solid understanding of embedded systems concepts, including real-time constraints, interrupts, direct memory access, memory hierarchies, and hardware/software interfaces.
  • Familiarity with at least one of DSP algorithm implementation, wireless modem software, or low-level driver or hardware abstraction layer development.
  • Experience with bare-metal or real-time operating system environments such as FreeRTOS, Zephyr, or equivalents.
  • Debugging skills across software and hardware boundaries, including use of logic analyzers, oscilloscopes, JTAG, and reading schematics when needed.
  • English proficiency at B1 level or higher.

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, including filtering, synchronization, modulation and demodulation, and channel estimation, on embedded targets and DSP cores.
  • Develop low-level system-on-chip software, including 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, direct memory access, 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.
  • Bring up and validate silicon, 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 shape hardware/software trade-offs early.
  • Contribute to test infrastructure, automation, and continuous integration for embedded software.

Desired Qualifications

  • Experience with wireless communication systems, including software-defined radio, modem baseband, Wi-Fi, 5G/LTE, or proprietary radios.
  • Hands-on experience with DSP cores such as Cadence Tensilica, CEVA, ARM Helium, or similar, and DSP-specific optimization.
  • Experience with fixed-point arithmetic and porting algorithms from MATLAB or Python references to embedded targets.
  • Experience with high-speed interface drivers such as JESD204B/C, MIPI CSI/DSI, or 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.

About the Company

Sine Engineering

GPS-denied, spectrum-resilient UAV connectivity solutions

Sine Engineering provides resilient connectivity solutions for unmanned aerial vehicles in GPS-denied and spectrum-challenged environments, aiming to keep drones controllable and connected in harsh conditions. Its products combine software-first capabilities with modular hardware that can be upgraded via over-the-air updates and easily replaced in production lines. The company differentiates itself by focusing on affordability and mass production, building on counter-UAS experience and serving multiple UAV manufacturers rather than end-user drones. Its goal is to enable widespread, low-cost deployment of capable drones in defense and aerospace, even when signals are limited or jammed.
