Senior System Firmware & FPGA Engineer – Digital Oscilloscope Biba Electronics | R&D; / Embedded Systems | Full-time | 7–8 years’ experience

About the role
Biba Electronics is looking for a senior engineer to lead FPGA development, the embedded Linux platform, processor-board software and system-level integration for a high-performance digital oscilloscope. You will own the embedded architecture that connects the processor, FPGA, high-speed ADCs, acquisition memory, display, storage, communication interfaces and measurement subsystems. The role combines strong FPGA design, embedded Linux and driver development, DSP fundamentals and system integration. You will work closely with the hardware, application software, mechanical and testing teams to deliver a secure, high-performance instrument.

• Identify and resolve bottlenecks in throughput, latency, memory bandwidth, synchronization and CPU load. FPGA development
• Develop RTL in Verilog/SystemVerilog (VHDL acceptable).
• Build high-speed ADC capture interfaces (LVDS or JESD204B/C).
• Implement acquisition control, trigger detection (edge, pulse-width and others), pre/post-trigger buffering and continuous acquisition.
• Design acquisition memory controllers, DMA paths, FIFOs and DDR integration.
• Implement channel sync, decimation, digital filtering and hardware-assisted measurements.
• Build FPGA-to-processor interfaces using AXI, PCIe, Ethernet, SPI or parallel buses.
• Handle timing closure, constraints, clock-domain crossings, resource optimization and ILA-based debugging. Embedded Linux platform
• Bring up embedded Linux: bootloader, kernel, device tree, root filesystem and startup.
• Develop kernel drivers for FPGA interfaces, acquisition hardware and board peripherals.
• Build userspace services for instrument control, acquisition management and monitoring.
• Optimize memory, interrupts, DMA and system responsiveness.
• Integrate Ethernet, USB, storage, display and serial interfaces.
• Implement logging, diagnostics, watchdogs, error recovery, secure boot and software updates.
• Maintain reproducible builds with Yocto,



Buildroot or the vendor SDK. High-speed data acquisition
• Own the full data path from ADC sampling through FPGA capture to processor-side processing.
• Design configurable record lengths, multi-channel synchronization and pre/post-trigger capture.
• Optimize sustained and burst throughput while minimizing data copies.
• Handle start/stop, trigger events, buffer overflows and data integrity. DSP and measurements
• Implement decimation, filtering, interpolation, averaging, peak detection and FFT processing.
• Support measurements such as frequency, period, amplitude, RMS, rise/fall time, duty cycle and pulse width.
• Partition algorithms across FPGA and processor, and validate accuracy, latency and consistency. System integration
• Integrate display, touch, storage, USB and Ethernet peripherals.
• Develop APIs and IPC between system services and the oscilloscope application.
• Implement configuration, acquisition control, calibration-data access and status reporting.
• Ensure reliable operation under continuous acquisition and long-duration testing. Debugging and validation
• Debug FPGA, Linux, driver and hardware-interface issues at system level using JTAG, ILAs, Linux tracing tools and lab instruments.
• Run FPGA simulation, regression and hardware-in-the-loop tests.
• Measure throughput, trigger latency, waveform update rate, memory use and CPU load.
• Diagnose dropped samples, corrupted records, DMA failures and timing violations.
• Support bring-up, prototype validation, reliability testing and release qualification, with full documentation and source control. Required skills
• FPGA: RTL design, simulation, synthesis and timing closure
• High-speed interfaces: ADC capture, LVDS, JESD204B/C
• Embedded Linux: kernel configuration, bootloader, device tree, rootfs and bring-up
• Linux drivers: character/platform drivers, interrupts, DMA, register access
• Programming: strong C; C++ and Python are advantages
• Data acquisition: sampling, triggering, buffering and data integrity
• Memory systems: DDR, DMA, FIFO and bandwidth optimization
• DSP: FFT, filtering, decimation and measurement fundamentals
• Debugging: JTAG,



logic analyzers, oscilloscopes, FPGA debug tools
• Software engineering: Git, code reviews, automated testing, release management Tools and platforms (hands-on with several of these)
• FPGA: AMD/Xilinx Vivado and Vitis, Intel Quartus Prime, ModelSim/Questa, ILAs, AXI IP integration
• Embedded Linux: ARM-based SoCs, Yocto/Buildroot, U-Boot, GCC, GDB, Make/CMake, perf, ftrace, strace
• DSP and verification: FFT/filter libraries, DMA-based acquisition, MATLAB/Simulink or Python scientific libraries Qualifications
• B.
E./B.
Tech in ECE, EE, Computer Engineering or a related discipline
• M.
E./M.
Tech in Embedded Systems, VLSI or Signal Processing is an advantage
• 7–8 years of professional experience across FPGA development, embedded Linux and system-level engineering Preferred experience
• Oscilloscopes, digitizers, spectrum analyzers, SDR or high-speed DAQ products
• High-speed ADC–FPGA integration and sustained high-throughput capture
• Zynq / Zynq UltraScale+ MPSoC, Intel SoC FPGAs or equivalent
• DDR controllers, PCIe or high-speed Ethernet
• Deterministic triggering and multi-channel synchronization
• FFT-based spectrum analysis and measurement algorithms
• Automated hardware validation and production diagnostics Key deliverables
• System-level processor, FPGA and firmware architecture
• FPGA RTL for ADC interfacing, acquisition, triggering, buffering and data transfer
• Embedded Linux bring-up, drivers, device trees and userspace services
• Processor–FPGA communication and high-speed DMA paths
• Acquisition-control and measurement software
• Integrated firmware image, build scripts and deployment procedure
• Diagnostics, error handling, recovery and logging
• Validation tools, performance reports, source code and documentation handover Who we’re looking for A system-level engineer who understands the whole instrument, from ADC sampling to the waveform on the display. You’re comfortable debugging hardware–FPGA–Linux interactions, optimizing high-throughput data paths and independently owning major integration milestones. This role needs meaningful experience across FPGA development, embedded Linux and system integration. Candidates whose background is only Linux application development or basic FPGA RTL will not be a fit. If your strength is in one area, you should be able to show substantial hands-on capability in the others.
