Job description

Job Overview

We’re looking for an enthusiastic & talented server side engineer, to join one of our high-impact teams inside Citi’s CTO organisation. You’ll sit within Developer Enablement, a group focused on innovation, developer platforms and internal tools used across the bank, where we experiment and ship fast, like a startup inside a global bank. Our mission is to drive productivity by streamlining/automating processes & make the best tools available for our 30k engineers. At Citi’s scale saving tens of minutes per day, equates to £10,000,000s of savings. We believe happy engineers make the best engineers and are a technology managed department.

What you will do:

• Write code and deliver. You are a delivery focussed engineer for our back end services.
• That means contributing high-quality code regularly, not just reviewing other people\'s. You set the bar through your own work.
• Shape how we build. You\'ll have a real voice in our architecture and technical roadmap. Your opinion matters.
• Stay ahead of GenAI. This space moves fast. We need someone who follows it seriously, brings new ideas back to the team, and actively applies what they\'re learning to the products we build.
• Be a team player. Thoughtful code reviews. Unblocking people when they\'re stuck. Sharing what you know. Your success here is tied to the team\'s success, not just your own output.
• Communicate like it matters. We\'re distributed across three continents. Clear, direct, proactive communication isn\'t a soft skill here. It\'s how the work gets done. You\'ll model it.

What you should have:

A selection of the tools and capabilities required across our platforms. We value multi-disciplined polyglot engineers but also understand and support the need for specialisms too across the wider department.

• Proven experience delivering within technical projects
• Deep, hands-on experience building and running production-grade services. You\'re still writing code regularly. You\'re good at it
• Strong server-side engineering skills: Kotlin or Java (we’re using Java 21), building and consuming RESTful APIs.
• Proficiency with relational and/or NoSQL databases: Couchbase, PostgreSQL or MongoDB.

Highly Desirable skills

• Experience with event-driven architecture.
• Experience with microservice architecture
• Contract first APIs, such as swagger.
• Experience with message queuing systems: Apache Kafka.
• SRE/DevOps – Experience with scalability & Observability
• Understanding of containerization (Docker) and orchestration (Kubernetes).
• Familiarity with CI/CD tools and automated deployments.
• Comfortable collaborating with product, design, and UI engineers, product managers, and other stakeholders to understand requirements and deliver robust backend solutions.
• AI experience is highly desirable but not mandatory

Tools you’ll use

• Server: Kotlin, Java, Spring Boot, http4k, ktor, PostgreSQL, MongoDB, Apache Kafka, Docker, Kubernetes, Helm, Tekton, Harness
• Infra: OpenShift, Tekton, Harness
• Mac or PC - It’s up to you.
• Access to time-saving AI tools such as GitHub Copilot, Cognition.ai’s Devin and Claude Code

What we’ll provide you

By joining Citi Belfast, you will be part of a business casual workplace with a hybrid working model (up to 2 days working at home per week), and receive a competitive base salary (which is annually reviewed), and enjoy a range of benefits.
