Developer Enablement, Java/Kotlin Software Engineer (SVP) - Citi

Job Overview
We’re looking for an expert level server side engineer, to join one 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.

Opportunities in CTO

There are many exciting opportunities for you, and flexibility to move between multiple projects if that’s something you’d enjoy. Two closely related key strategic projects will require your expertise driving solutions are as follows:

SDLC Automation is a greenfield initiative 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 at Citi, taking ideas like grading engineering teams and rewarding those who follow best practices, perhaps moving them from manual approval process to an automatic one. The use of Artificial Intelligence is planned to further automate and remove manual human led processes that add toil to the SDLC process

Release on Demand (RoD)is our strategic release management platform that makes it trivial to generate production run books & ServiceNow Changes with the click of a button. Built internally approximately three years ago the platform has quickly become our strategic release generation and deployment tool used across all lines of business. Last year it generated 60k releases and automated the deployment of approx. 65% of them.

RoD enables cultural change within development teams enabling them to move quickly but whilst maintaining quality gates to ensure the correct SDLC and procedural requirements of the firm are upheld, whilst driving industry best practices (DORA)

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 and lead small, agile team, in an organisation led by technologists and use the latest AI tooling to complete your work.
You’ll impact the daily experience of tens of thousands of engineers at one of the largest engineering organisations in the world.
Our culture runs on engineering craftsmanship. Leadership here actually understands what that means. We’re proving what’s possible inside a large organisation, and that means navigating some legacy alongside building the future. If you want everything perfect on day one, this isn’t the right fit. If you want to help us get there, keep reading.
The team is distributed across Belfast, Canada & London. You’ll work closely with engineers across time zones and partner directly with product and platform leadership.

What you will do

Write code and lead. You’re the technical anchor for our backend services. That means contributing high-quality code regularly, not just reviewing other people’s. You set the bar through your own work.
Own the hard stuff. Core platform capabilities are yours: background jobs, autonomous agents, the services that keep everything running. You’ll build for reliability and performance, and you’ll be accountable when things need fixing.
Shape how we build. You’ll have a real voice in our architecture and technical roadmap. You’ll work directly with the product owner to make sure we’re building the right things, in the right order, for the right reasons.
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. If you’ve been experimenting with new models, new tooling, or new patterns, that’s exactly the kind of thinking we want in the room.
Make the team better. 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 muti-disciplined polyglot engineers but also understand and support the need for specialisms too across the wider department.
Proven experience leading technical projects and mentoring engineers
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 (depending on role)

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
This is a unique role that will put you in the position to be part of a new venture and actively drive change. Every day there will be new challenges that will help you develop new skills that can drive your career.
By joining Citi London, you will not only be part of a business casual workplace with a hybrid working model (up to 2 days working at home per week), but also receive a competitive base salary (which is annually reviewed), and enjoy a whole host of additional benefits such as:

27 days annual leave (plus bank holidays)
