Principal System Architect

This role is part of AccelerComms Systems Engineering team and provides senior technical leadership across the development and deployment of our communications products and IP. Working across systems algorithms software FPGA and ASIC development you will help define product architectures and ensure that system product and customer requirements are translated into practical scalable implementations.

This role would suit a highly experienced systems engineer or architect who combines deep communications and implementation expertise with the ability to establish technical direction influence across organisational boundaries and represent complex technology confidently with customers and partners.

Key Responsibilities

As a Principal System Architect you will provide cross-functional technical leadership across the wider organisation working with engineering product and commercial teams to establish technical direction and maintain alignment between customer needs product strategy and engineering implementation. You will also support other engineers and architects through technical guidance review and mentoring.

A significant aspect of the role involves providing architectural leadership as AccelerComms communications IP develops across FPGA and ASIC deployment targets. You will lead the evaluation of architectural options and implementation trade-offs balancing performance resource power verification and integration considerations. Experience of developing communications modem or signal-processing products together with a strong understanding of architectural and implementation considerations is highly desirable.

You will work across the engineering organisation to provide technical direction on requirements system decomposition interfaces architectural modelling performance analysis and verification strategy. The role requires the ability to engage at both system and implementation level working across disciplines to resolve complex technical issues and maintain architectural coherence across products and development teams.

An equally important part of the role is working directly with customers and partners to understand their systems requirements and deployment challenges. You will lead technical discussions and studies assess how AccelerComm technology can be applied within customer architectures and guide integration into FPGA and ASIC-based products. Insight from these engagements will help shape product requirements architectural direction and longer-term technology planning.
