Senior Developer Experience Engineer, 9fin

• You don't need prior DevOps, SRE or Platform experience for this role. We're just as interested in strong software engineers who want to specialise in building for other engineers as we are in people who've already worked in DevEx
• You are a strong software engineer with experience designing, building, testing and operating production software
• You are proficient in at least one modern programming language. We care more about engineering fundamentals than a particular language
• You understand the software development lifecycle and have practical experience improving how software is built, tested, deployed or operated
• You have strong opinions about what makes software development effective, while remaining pragmatic about different teams and contexts
• You can design maintainable systems and make sensible trade-offs between speed, quality and complexity
• You have some exposure to CI/CD, containers or cloud infrastructure — depth here matters less than curiosity
• You enjoy building tools and platforms for other engineers
• You take a product approach to internal tooling: understanding user needs, validating solutions and measuring adoption
• You can independently own a problem from discovery through to delivery and adoption
• You communicate clearly through code, documentation and technical discussions
• You have a real appetite for learning and self-improvement
• This role is right for you if you get real satisfaction from making other engineers faster and safer — even when it's invisible, thankless work most of the time
• If you’re excited about this role but your experience doesn’t perfectly align with the job description, we encourage you to apply anyway. You might just be who we’re looking for — either for this role, or perhaps another

Desirable

• We are looking for a Senior Developer Experience Engineer to help make software development at 9fin faster, simpler and safer
• This is a software engineering role focused on the tools, systems and paved roads that other engineers use. You will work across the software development lifecycle, from creating a new service through to testing, deployment, observability and operating it in production
• You will join an established Platform team and work alongside our existing Developer Experience Engineer. You will speak directly with engineers, understand where they are losing time or carrying unnecessary complexity, and build solutions that teams want to adopt
• Your customers are 9fin's software engineers. You will have the autonomy to solve problems that help them build products quickly, securely and to a high standard of quality
• The goal is not to centralise every engineering decision within Platform. It is to give teams sensible defaults, effective self-service tools and a clear path to production
• Building and maintaining internal tools, services, APIs and command-line applications
• Improving workflows across coding, testing, code review, deployment and production operations
• Creating service templates and paved roads that make it easier to build secure, observable and reliable software
• Improving the speed, reliability and usability of our CI/CD systems
• Developing reusable platform capabilities that product engineers can consume through self-service
• Helping engineers use observability effectively, with good defaults for logs, metrics, traces and service-level indicators
• Working directly with engineers to understand friction, test ideas and support adoption
• Using feedback and workflow data to measure whether changes have improved the developer experience
• Contributing production-quality code, tests, documentation and operational support
