FPGA/DSP Engineer

Vescent Technologies seeks an FPGA / DSP Engineer to lead the transition of high-performance precision laser and frequency control architectures from traditional analog and hybrid implementations into scalable, FPGA-centric digital platforms. This role sits at the intersection of digital signal processing, embedded hardware design, control theory, and atomic/molecular/optical (AMO) physics. The ideal candidate is excited by technically difficult problems involving ultra-low-noise control systems, high-speed signal processing, precision timing, and the physics of lasers, resonators, atoms, and photonic systems. They will work closely with physicists, electrical engineers, and systems engineers to develop industrial-grade digital control solutions for quantum technologies.

Responsibilities

• Architect and implement FPGA-based digital control systems for precision laser frequency stabilization, optical phase locking, and timing synchronization systems.
• Develop real-time DSP pipelines for applications including:

Digital PLLs and frequency synthesis

IQ demodulation and modulation

Lock-in detection

Digital filtering and servo control

Phase/frequency measurement and tracking

Timing distribution and synchronization

Noise characterization and suppression

• Translate laboratory-grade analog or mixed-signal frequency control techniques into robust FPGA-based digital architectures suitable for deployment and manufacturing.
• Design low-latency feedback systems for optical cavities, frequency combs, electro-optic devices, acousto-optic devices, and atomic spectroscopy systems.
• Collaborate with AMO physicists to understand system-level noise sources, instability mechanisms, and precision measurement limitations.
• Analyze phase noise, timing jitter, quantization effects, ADC/DAC limitations, and numerical precision constraints in high-performance digital control systems.
• Interface FPGA systems with high-speed ADCs, DACs, RF transceivers, timing hardware, and embedded processors.
• Participate in hardware bring-up, system integration, debugging, and experimental validation in laboratory and deployed environments.
• Develop simulation and verification environments for DSP algorithms and feedback control systems.
• Contribute to architecture decisions for scalable quantum control and timing platforms.
• Document designs, verification procedures, and performance characterization results for internal and customer-facing systems.
