PLATFORM ENGINEER

At OakNorth, we’re on a mission to empower the UK’s most ambitious businesses. Since 2015, we’ve lent over $21 billion across the UK and US, helped create more than 58,000 new homes and 36,000 new jobs, and supported hundreds of thousands of personal savers — all while fuelling the UK economy.

As we continue to scale, we’re looking for self-starters and bold thinkers who are excited to build on this success and help shape the next generation of financial products and platforms delivering real value to both individuals and businesses. We are looking for a Platform Engineer; you will be a key part of this mission, working to provide self-service infra, automation, and tools that enhance engineering effectiveness, reliability, and security.

• Design and build self-service infrastructure and developer tooling to enhance engineering effectiveness.
• Improve the developer experience by creating platform abstractions that reduce complexity and accelerate delivery.
• Enable teams to own and operate their services autonomously by continuously refining CI/CD pipelines and infrastructure as code (IaC).
• Improve system transparency for our teams by enhancing the observability stack using tools like CloudWatch, X-Ray and Grafana.
• Take initiative to identify inefficiencies in the platform and plan with Senior Engineers for the solutions to be included in the roadmap.
• Implement best practices for resiliency and reliability to ensure platform stability and reduce single points of failure.
• Work together with the Information and Cyber Security teams to help embed security best practices into infrastructure, CI/CD processes, and automation frameworks.
• Work closely with Product Engineering teams to understand their pain points and proactively improve platform capabilities.
• Partner with Senior Platform Engineers with a willingness to take initiative.
• Promote open communication, cross-team collaboration, and a culture of experimentation.
• Foster a culture of upward feedback that enables bidirectional growth.
• Help ensure a psychologically safe environment where team members can challenge ideas and solutions respectfully and share feedback openly.

• Experience in cloud platforms with a focus on building and maintaining platform services for developer enablement.
• Strong IaC concepts and language-agnostic automation skills.
• Hands-on experience with container orchestration platforms with a strong understanding of the core containerisation concepts.
• Experienced in designing, implementing CI/CD pipelines with an emphasis on deployment automation and reliability thus adding to developer experience.
• Knowledge of observability, logging, and monitoring best practices.
• A collaborative and product-minded approach, focusing on enabling engineering teams.
• Good communication skills that make it easy to understand complex technical ideas.
• A low ego working style that supports open collaboration and encourages everyone to share ideas.

• Collaborate - We work in cross-functional, mission driven, autonomous squads that gel over time.
• Focus on outcomes over outputs - Solving a problem for users that translates to business results is our goal.
• Practice continuous improvement - We optimise for feedback now, rather than presume what might be needed in the future.
• Seek to understand our users - We constantly seek understanding from data and conversations to better serve our users' needs.
• Embrace and enable continuous deployment - Seamless delivery of changes into an environment without manual intervention is essential for us.
• Test outside-in, test first - TDD keeps us confident in moving fast and deploying regularly.
• You build it, you run it - We embrace DevOps culture and end-to-end ownership of products and features.
• Be cloud native - We leverage automation and hosted services to deliver resilient, secure services quickly and consistently.

• We embrace difference and know that when we can be ourselves at work, we are happier, more motivated, and creative.
• A wide range of voices heard to the benefit of all.
• Teams that are clearly happy, engaged, and laugh together.
• Perceivable safety to have an opinion or ask a question.
• No egos - people listen to and learn from others at all levels.

• 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.
• Work-life balance - 25 days holiday (plus bank holidays) each year, and enhanced family leave allowances.
• Competitive salary.
• 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.
• Commuter support - We offer the cycle to work and EV scheme.
