Job description
Connect to your Industry
Do you want to lead the engineering delivery and shape the solution architect of some of the UK's largest and most ambitious Data & AI programmes?
Within Technology & Transformation organisations are increasingly relying on modern data platforms and AI to accelerate innovation, improve decision-making, and unlock new business value. As a Senior Databricks Data & AI Engineer / Technical Lead, you'll provide the technical leadership that enables these transformations—leading engineering teams, shaping solution architecture, and delivering enterprise-scale data, machine learning, and AI solutions on the Databricks Data Intelligence Platform.
Working alongside some of the industry's leading architects, engineers, and AI specialists, you'll help clients build secure, scalable, and high-performing data and AI platforms that power the next generation of intelligent applications.
Connect to your career at Deloitte
Deloitte drives progress. Using our vast range of expertise, we help our clients' become leaders wherever they choose to compete. To do this, we invest in outstanding people. We build teams of future thinkers, with diverse talents and backgrounds, and empower them all to reach for and achieve more.
What brings us all together at Deloitte? It’s how we approach the thousands of decisions we make every day. How we behave, our beliefs and our attitudes. In other words: our values. Whatever we do, wherever we are in the world, we lead the way, serve with integrity, take care of each other, foster inclusion, and collaborate for measurable impact. These five shared values lead every decision we make and action we take, guiding us to deliver impact how and where it matters most.
Connect to your opportunity
We're expanding our Databricks Engineering practice and are looking for experienced technical leaders who combine deep engineering expertise, solution architecture capability with strong delivery leadership. You'll work alongside exceptional data, AI, and cloud specialists to design, build, and deliver complex enterprise solutions while leading distributed engineering teams and shaping technical direction across multiple workstreams.
Depending on your strengths and client needs, you may focus more on hands-on engineering leadership and delivery, end-to-end solution and platform architecture, or a combination of both across enterprise Databricks transformation programmes. The ideal candidate will possess extensive hands-on expertise across the Databricks Lakehouse Platform, modern data engineering, machine learning, and Generative AI, while providing technical leadership, design authority, and engineering governance throughout the delivery lifecycle.
As a key member of our team, you will:
-
Lead the technical delivery and/or solution architecture of enterprise-scale Databricks Data & AI implementations from solution design through to production deployment.
- Act as the technical lead and design authority across multiple workstreams, ensuring solution quality, scalability, security, and alignment with engineering best practices.
- Lead and mentor onshore and offshore engineering teams, fostering technical excellence, collaboration, and continuous improvement.
- Drive engineering delivery by establishing technical standards, reviewing solution designs, managing technical risks, and ensuring successful execution against project objectives.
- Conduct code reviews and engineering quality assurance, promoting clean, maintainable, high-quality code and adherence to software engineering best practices.
- Optimise platform performance across Spark workloads, Delta Lake, data pipelines, storage, and compute to maximise scalability, reliability, and cost efficiency.
- Design and deliver enterprise-grade Machine Learning, Generative AI and Agentic AI solutions leveraging the Databricks Data Intelligence Platform, MLflow, Mosaic AI, Vector Search, and modern LLM capabilities where appropriate.
- Partner with solution architects, product owners, client stakeholders, and engineering teams to translate business requirements into scalable technical solutions.
- Coach and develop engineers through technical mentoring, knowledge sharing, and establishing reusable engineering frameworks and best practices.
- Own technical governance by maintaining engineering standards, architectural integrity, documentation, and design decisions throughout project delivery.
- Define enterprise solution and platform architectures on Databricks — producing reference architectures, blueprints, and target-state designs that span data engineering, ML, and Generative AI.
- Support solutioning and pre-sales by shaping proposals, estimating delivery, and advising client leadership on architecture strategy, platform roadmaps, and target operating models.
