AI NATIVE ENGINEER - AI ENABLEMENT

At OakNorth, we’re building a bank for ambitious businesses, and we believe the next step-change in how we build software comes from AI-native engineering.

The AI Enablement team exists to help product and engineering teams across the bank adopt AI practices and tools safely, effectively, and at scale, accelerating time-to-market while maintaining our high bar for quality, security, and reliability.

This is a senior, hands-on engineering role for people who already build with AI as part of their daily workflow and want to help others do the same.

Team Mission 🚀

• The AI Enablement team multiplies impact across OakNorth primarily:
• As enablers, we partner with product and engineering teams to adopt AI practices and tools safely and effectively by building internal platforms, agents, and workflows that eliminate friction and accelerate delivery throughout the software development lifecycle.
• As builders, we experiment with and ship AI-native product features across OakNorth’s product portfolio. Proving what's possible, establishing patterns, and moving fast without a long-term ownership burden.
  
  
  

In everything we do, we establish safe, governed, and scalable patterns for AI adoption across the bank. We learn fast and help others learn faster. Our success is measured by how effectively we accelerate software delivery across the organisation through AI-native ways of working.

The Role 👋

• As a Senior AI-Native Engineer, you will design, build, and operate AI-powered systems that directly improve how software is developed and operated at OakNorth. At this level, you'll operate with significant autonomy, shape solutions end-to-end, and influence AI adoption across multiple teams.
  
  
  

You will:

Build production-grade AI tools and agents that support the full development lifecycle:

• Product ideation and discovery
• Technical specification review and early feedback
• Code generation, refactoring, and review
• Documentation generation and maintenance
• Test generation and quality validation
• Observability, log analysis, and incident support
  
  
  

Ship AI-native product features for core OakNorth products:

• Experiment with AI-powered capabilities across our product portfolio
• Move from concept to production quickly, proving what's possible
• Establish reusable patterns and hand off to product teams for long-term ownership
• Balance rapid experimentation with production-quality delivery
  
  
  

Deliver AI-enabled workflows end-to-end, such as:

• Agents that inspect logs and metrics to surface bugs, risks, or performance issues
• Automated pull requests with proposed fixes or improvements
• AI-assisted review of design documents and architectural decisions
  
  
  

Own initiatives from discovery to adoption: problem framing → solution design → implementation → rollout → measuring impact

Partner with product and engineering teams to embed AI tools into daily workflows, ensuring real adoption and measurable outcomes

Define standards and guardrails for AI usage in a regulated, security-conscious environment

Raise AI fluency across the organisation by sharing learnings, patterns, and examples that help others level up

What We’re Looking For 🧠

• Strong engineering fundamentals
• 5+ years building and operating production systems
• Comfortable working full-stack or with deep expertise in backend/platform engineering
• Proven track record in designing and building systems used by other engineers

Strong product mindset: you measure success by outcomes and adoption, not just output

Skilled at rapid experimentation: you're comfortable with uncertainty, test ideas by shipping quick prototypes, and learn as much from failures as successes

Skilled at breaking down ambiguous problems into practical, scalable solutions

Already AI-native

• You're already in the habit of:
• Using AI tools daily to accelerate your work (coding, debugging, reviews, documentation)
• Treating AI as a collaborator in your workflow, not a novelty
• Thinking in terms of agents, workflows, and automation
• Iterating quickly: experiment → learn → refine → scale
  
  
  

You've experienced firsthand how AI-native tools transform productivity, tools like Cursor, Claude Code, ChatGPT, Lovable, and others. What matters is a track record of quickly learning and integrating new AI tools into your workflow.

Nice to have

• Experience building or orchestrating AI agents or multi-step workflows
• Familiarity with LLM APIs, prompt engineering, or tool-calling patterns
• Background integrating AI into CI/CD pipelines, observability, or developer tooling

Experience working in regulated environments (financial services, security-sensitive systems)

Technology 🧱

• We’re pragmatic and evolving fast. Today, you’re likely to work with:
• 🐍 Python
• 🧠 LLMs & AI tooling (we're outcome-driven and vendor-agnostic)
• 🗄️ PostgreSQL, BigQuery
• 🎨 TypeScript, React
• 🔧 pytest, Jest, CI pipelines
• ☁️ AWS, GCP
• 🚀 Docker, Terraform, GitHub Actions
  
  
  

More important than specific tools is your ability to learn fast, adapt, and choose the right abstraction.

How We Expect You To Work 👷‍♀️

• Enable, don’t block – you build platforms and tools that make other teams faster and more confident
• Outcome-driven – success is measured through adoption, time-to-market, and quality improvements
• Iterative by default – start small, validate value, then scale
• Hands-on ownership – you build, ship, and operate what you create
• Collaborative – you work across squads, disciplines, and seniority levels
• Pragmatic about risk – especially when introducing AI into production and regulated systems

Our story

OakNorth Bank was built on the foundations of frustrations with old-school banking. In 2005, when our founders tried to get capital for their data analytics company, the computer said ‘no’. Unfortunately, all major banks in the UK were using the same computer – and it was broken.

Why was it so difficult for a profitable busines

s with impressive cashflow, retained clients, and clear commercial success to get a loan?

The industry was backward-looking and too focused on historic financials, rather than future potential.

So, what if there was a bank, founded by entrepreneurs, for entrepreneurs? One that offered a dramatically better borrowing experience for businesses?

No more what ifs, OakNorth Bank exists.
