Senior Software Engineer - Java/Kotlin (Developer Enablement) - Vice President in Belfast

We’re looking for multiple talented engineers 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 save our engineers tens of minutes per day, equating to £10,000,000s of savings at Citi’s scale.

Opportunities in CTO:

• SDLC Automation – a greenfield project that builds on the success we’ve had in automating the SDLC and takes it further. This blue‑sky project looks at ways we can greatly improve the SDLC process recruited at Citi, taking ideas like grading engineering teams and rewarding those who follow best practices, perhaps moving them from a manual approval process to an automatic one. The use of Artificial Intelligence is highly likely.
• Dev hub – the Engineers homepage where engineers can see all parts of the SDLC, such as code reviews, JIRA imports, deployments, all tied together into a single workflow. The next‑generation greenfield Developer Experience (DevEx) platform aims to save days of engineering time per engineer per year at one of the largest engineering organisations in the world.

Why you’ll love working here:

• You get to work in the engineering focused part of the bank, the Chief Technology Office, building tools for other engineers.
• You’ll work in a small, agile team, in an organisation led by technologists.
• You’ll impact the daily experience of tens of thousands of engineers at one of the largest engineering organisations in the world.

What You Will Bring:

• 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 across the wider department.
• Server – Strong server‑side engineering skills: Kotlin or Java (using Java 21), building and consuming RESTful APIs. Proficiency with relational and/or NoSQL databases: PostgreSQL, MongoDB.

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 containerisation (Docker) and orchestration (Kubernetes).
• Familiarity with CI/CD tools and automated deployments.
• Comfortable collaborating with product, design, UI engineers, product managers, and other stakeholders to understand requirements and deliver robust backend solutions.

Tools you’ll use (depending on role):

• Server: Kotlin, Java, Spring Boot, http4k, ktor, PostgreSQL, ASI, 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 and Cognition.ai’s Devin.

Don’t tick every box? Don’t worry, if you’re talented our team would like to chat to you. Our team has diverse backgrounds with former entrepreneurs, multi‑disciplined practitioners, and people from all over the world. We have many roles within the same Developer Enablement group that are open, and we can find a role, or even create one that fits you.

What We’ll Provide You:

• By joining Citi Belfast, you will not only be part of a business casual workplace with a hybrid working model (up to two days working at home per week), but also receive a competitive base salary (annually reviewed), and enjoy a host of additional benefits such as:
