Job Description

Our mission at vector8 is to elevate organisations by unlocking the true value of AI, getting the best from Human‑Machine collaboration. We have a culture grounded in inclusivity, curiosity, ownership, and collaboration, where your ideas shape the future of AI consulting.

We believe that over the next decade, every business will become an AI business and that a new era of AI transformation will enable greater leaps than ever before. We see a world where the seamless integration of human expertise and advanced AI technologies sparks unparalleled growth, efficiency, and resilience across all sectors.

vector8 collaborates with ambitious enterprises to address these challenges by adopting a unique strategy that merges the strengths of a product vision and custom development expertise. We deliver tailor‑made, fine‑tuned, optimised, and compliant AI solutions swiftly and affordably, leveraging AI Accelerators that tackle common industry problems and can be adapted and combined to build and deploy targeted use cases in production.

The Lead Architect plays a pivotal role at vector8. You will define, design, and build enterprise‑grade data and AI solutions, exercising and developing your skills not only as an architect, but as a hands‑on solution designer and occasional coder, who shapes systems and guides teams through implementation.

You bring deep expertise in enterprise and solution architecture for data and AI, combined with the willingness and ability to dive into code, validate architectural decisions, and help delivery teams move forward. You are comfortable navigating complex system landscapes, legacy environments, and strict requirements around security, compliance, and data protection.

You will design the cloud, data, and AI foundations that enable organisations to scale AI from individual use cases to a sustainable, enterprise‑wide capability.
