Job description
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
How We Expect You to Behave ❤️
- Curious, open, and generous with knowledge
- Strong opinions, held loosely
- Comfortable saying “this didn’t work, here’s what we learned”
- No ego, impact matters more than ownership
- Actively contribute to a psychologically safe, inclusive engineering environment
What Makes Working Here Better 😍
- This is a truly hybrid role, offering engineers the flexibility to work from home while also providing opportunities to collaborate in person with the team when it adds value. There’s no fixed requirement for days in the office, instead, we focus on creating space for engineers to engage meaningfully, whether that’s in-person for whiteboarding sessions or remote for deep focus work.
- Work-life balance 🌴 - 25 days holiday (plus bank holidays) each year, and enhanced family leave allowances.
- Competitive salary & equity 🏦 - We want people to have a serious stake in the business.
- Good kit 💻 - Your choice of the best laptop, running macOS.
- Team socials 🎉 - The opportunity to get to know each other outside of work.
- Company socials 🥡 - A chance to catch up and meet new colleagues weekly over informal office breakfasts Lunches and dinners on OakNorth - or at our free barista bar every day.
- Commuter support 🚲 - We offer the cycle to work and EV scheme.
