## Description

An exciting opportunity for an experienced Senior System Architect to join a highly technical engineering team developing advanced, high-performance technology.
You will help shape complex products from initial requirements through to implementation, working across software, FPGA and ASIC technologies. Combining architectural design with practical engineering, you will influence technical decisions, evaluate implementation options and support delivery throughout the development lifecycle.
This role would suit an experienced systems engineer or architect who enjoys solving complex technical problems and working closely with multidisciplinary teams.
Key Responsibilities:
Translate system, product and customer requirements into practical, scalable architectures.
Define hardware/software partitioning, interfaces and implementation strategies.
Evaluate design trade-offs across performance, throughput, latency, resource usage and power.
Develop architectural models, conduct performance analysis and support verification planning.
Collaborate with software, algorithm, FPGA and ASIC engineers throughout development.
Work with customers and partners on technical requirements, feasibility studies and product integration.
Contribute to future product development and architectural improvements.
