• Producing and reviewing architectural models, design artefacts and technical documentation.
• Supporting customer engagement, bids, capture activities and technical reviews.
• Ensuring solutions are delivered to required cost, schedule and quality commitments.
• Influencing product evolution and technology roadmaps to maintain long-term solution viability.
