As a Senior / FPGA Engineer for Software Defined Radio (Baseband), you will be responsible to architect, implement, and validate baseband signal processing pipelines on modern FPGAs, integrating with high-speed ADC/DACs and RF front-ends. You will own the end-to-end flow-from algorithm prototyping to RTL implementation, timing closure, hardware-in-the-loop (HIL) validation, and production readiness. You will work on RF, embedded software, systems, and test engineering to deliver robust, scalable, and high performance SDR products.

Architecture & Design

• Define SDR baseband architectures (DDC/DUC, filtering, FFT/IFFT, OFDM, MIMO/beamforming, automatic gain control, synchronization, timing/phase tracking).
• Partition algorithms across FPGA fabric, DSP blocks, and embedded CPU (SoC) for performance/latency/power trade-offs.
• Develop high-speed I/O subsystems (e.g., JESD204B/C, PCIe, 10/25/100GbE, Aurora, AXI4).

Implementation & Verification

• Implement DSP and control logic in VHDL/Verilog/System Verilog; leverage Vendor IP and HLS where appropriate.
• Perform timing closure (setup/hold, CDC, multi-clock design), resource/power optimization, and floor planning.
• Build test benches, UVM/lightweight verification, and hardware-in-the-loop tests with real RF signals.

Modeling & Prototyping

• Prototype algorithms in MATLAB/Simulink or Python (NumPy/SciPy); ensure fixed-point accuracy and bit true correlation with RTL.
• Develop golden reference models and maintain test vectors for continuous verification.

Integration

• Interface with RF front-end (mixers, LNAs, filters) and high-speed converters (ADC/DAC), including clocking, PLLs, and synchronization.
• Collaborate with firmware/software teams on drivers, DMA, kernel modules (Linux), and data path APIs.
• Integrate with SDR frameworks (e.g., GNU Radio, custom pipelines) and external control planes.

Validation & Production Readiness

• Execute lab bring-up using spectrum analyzers, VNAs, logic analyzers, and oscilloscopes.
• Conduct EVM, BER, throughput/latency, spur/noise, and phase-noise/jitter characterization.
• Support DFx (DFT/DFM), manufacturing test, and field diagnostics; contribute to compliance (EMC/EMI) planning.

Process & Documentation

• Maintain requirements, interface specs, state machines, test plans, and design reviews.
• Adopt Continuous Integration/Continuous Deployment practice workflow for FPGA builds, regression tests, and continuous integration.

• Knowledge in Electrical Engineering, Communications Engineering, Computer Engineering, or related field.
• 3-7 years of experience in digital communications, DSP, or baseband algorithm development (drone/telemetry experience preferred).
• Experience with embedded systems and real-time signal processing.
• Hands-on exposure to FPGA/DSP hardware platforms and RF lab test equipment.
• Strong knowledge of digital modulation/demodulation schemes (FSK, QPSK, QAM, OFDM, etc.).
• Proficiency in forward error correction (FEC) methods (convolutional codes, RS, LDPC).
• Expertise in digital filter design (FIR, IIR, adaptive filtering, equalization).
• Skilled in DSP implementation on FPGA/DSP/embedded platforms (e.g., Xilinx, TI DSPs).
• Proficiency with MATLAB, Simulink, Python, C/C++ for simulation and implementation.
• Familiarity with RF test equipment (spectrum analyzers, VSAs, oscilloscopes).
• Willingness to participate in field trials and real-world testing under varying RF conditions.
• Willing to station at customer's office
• Singaporean only

• An environment where you will be working on cutting-edge technologies and architectures.
• Safe space where diverse perspectives are valued, and everyone's unique contributions are celebrated.
• Meaningful work and projects that make a difference in people's lives.
• A fun, passionate and collaborative workplace.
• Competitive remuneration and comprehensive benefits.
