About

Hybrid Electronics Designs Ltd

is a UK-based specialist engineering company, founded in 2018. It operates across defence, secure communications, and safety-critical sectors — delivering FPGA design, verification, and embedded systems engineering for programmes where reliability is key.

Services include technical consulting, project delivery, and training for engineering teams.

Background

Priyank Krishnani, founder of Hybrid Electronics Designs, is an FPGA design and verification engineer with twelve years of experience in digital electronics engineering. His work spans radar signal processing, cryptographic platforms, Ethernet IP encryptors, nuclear safety systems, and submarine power electronics — predominantly across the UK defence sector.

Alongside this, he holds an MBA from Imperial College London and is actively developing expertise in FPGA applications for financial infrastructure — an area driven by the same low-latency, high-reliability constraints that define defence engineering.

Experience

Current Focus
Deliberate expansion beyond defence delivery. Building software capability in Python and C++, developing FPGA expertise for financial infrastructure, and deepening understanding of low-latency systems design.
2018–2025
Contract
Ultra Electronics · Frazer-Nash · Thales · L3Harris · Leonardo · MASS Consultants
