Job description

This Google Cloud partner helps organisations get real value from Google Cloud across cloud, data, AI and agentic systems, with fast-growing demand around Gemini Enterprise. Their engagements take clients from strategy through to production and sit alongside their teams, shape the technical direction, and build the platforms.

As a member of their architecture team, you’ll work mainly with major telecoms clients on large-scale GCP and hybrid environments. Clients will rely on you as their go-to technical voice. You’ll be the person who turns ambiguous business problems into platforms that work in production. The work spans data, AI, platform engineering, DevOps, and migrations.

At this firm, a Lead Architect is a hands-on technical leader. Around three-quarters of the role is building and the rest is design leadership: setting direction, running workshops, and presenting to client stakeholders. You’ll own the technical quality of what they deliver and act as an ambassador for their engineering standards.

This is a hybrid role, with a minimum of three days a week in their central London office or at client sites in London.

What you will do...

• Design and deliver data platforms and pipelines covering ingestion, transformation and serving, using BigQuery, Dataflow, Pub/Sub and Cloud Composer.
• Architect end-to-end cloud solutions across infrastructure, networking, security and application layers that are scalable, resilient and built for production.
• Design AI, ML and agentic solutions using Vertex AI, Model Garden and Gemini as client demand grows.
• Lead the technical planning and execution of cloud and data migrations, choosing the right approach for each workload, from lift-and-shift to full re-architecture.
• Run discovery workshops, produce architecture artefacts, and present recommendations to everyone from engineering teams to senior stakeholders.
• Spot technical risk early and build security, compliance and performance in from day one.
• Act as a player-coach, guiding junior engineers and contributing to our architectural standards and reusable design patterns.

Who we need...

• 6+ years in cloud engineering or architecture, with a track record of designing and delivering production platforms.
• Deep, hands-on experience with at least one major cloud platform (GCP, AWS or Azure). Strong AWS or Azure architects who want to move into GCP are welcome, and we’ll support you through certification.
• Real data experience, such as data migrations, pipeline design and data management.
• A clear, confident communicator who can explain complex technical ideas and their business impact to technical and non-technical audiences.
• A sharp problem-solver who’s comfortable with ambiguity and wants to keep learning.
