Senior FPGA Architect | Remote & Impactful Security Systems

Entrust; Cambridge; Hybrid; GBP 90,000 - 130,000; Full time

Job summary

Entrust is seeking a technical leader to design and deliver FPGA-based solutions within security-focused systems. You will own FPGA architecture, implementation, and integration, and contribute to system-level design while remaining a hands-on contributor.

You will drive technical direction, estimation, and execution across FPGA workstreams, mentor engineers, and collaborate with hardware, software, and product teams to meet platform objectives. Flexible work options are available.

Qualifications

• Degree (or equivalent) in Electronic Engineering, Computer Science, Mathematics, or related discipline.
• Experience designing and delivering complex FPGA-based systems, including VHDL RTL design.
• Experience with synthesis, place & route, and timing closure.
• Verification methodologies (simulation, testbenches, coverage).
• Xilinx FPGA architectures and toolchains.
• Experience translating algorithms into efficient FPGA implementations, optimised for performance, area, and power.
• Experience integrating FPGA designs into hardware/software systems, including bring-up and debugging.
• Software development experience (e.g. C or Python) to support tooling, test, or integration.
• Experience working in Linux and/or Windows development environments.

Responsibilities

• Leads the design, implementation, verification, and debug of VHDL-based FPGA solutions for new and existing products.
• Owns FPGA architectural design, including partitioning, interfaces, and performance trade-offs within system constraints.
• Drives integration of FPGA components with embedded and host software systems, ensuring robust and scalable solutions.
• Defines and structures FPGA development work, translating requirements into deliverable tasks and clear technical plans.
• Provides estimates for FPGA activities, ensuring plans are realistic, risks are understood, and dependencies are identified.
• Coordinates and balances FPGA work across engineers, aligning tasks to skill levels and supporting effective team delivery.
• Guides day-to-day execution, providing technical direction and unblocking engineers during implementation.
• Identifies and mitigates technical risks and delivery bottlenecks.
• Defines and evolves FPGA development processes, including configuration management, CI/CD, and verification practices.
• Contributes to system architecture, working with hardware, software, and product teams to define platform capabilities.
• Leads resolution of complex technical challenges (e.g. timing closure, resource optimisation, system integration).
• Mentors and develops engineers through technical guidance, design reviews, and knowledge sharing.
• Collaborates across teams to ensure alignment of FPGA deliverables with system and product objectives.
