Job Description

Citywire's data platform powers products across the company, both internal and external, from our industry ratings to our growing estate of production AI systems. We're hiring a Data Engineer to help build the pipelines and data models at the heart of it - taking requirements from stakeholder teams and turning them into tested, scheduled, monitored production systems. This is a growth role by design. You'll work directly with, and be mentored by, the platform lead - on architecture, on production engineering discipline, and on working effectively with AI coding agents at production scale.


What you'll be doing:

  • Production data modelling: Translate analyst requirements and SQL into robust, production-grade dbt models (source 12 warehouse 12 reporting layers). You'll own data contracts, documentation, testing, and scheduling, with orchestration managed via Prefect.
  • Large-scale fund and manager performance computation: Help decompose a legacy performance engine into a modern, event-driven AWS architecture (EventBridge, SQS, Lambda, S3, RDS). You'll build parallel compute pipelines using Spark on EMR (no deep prior Spark experience needed, just a strong curiosity for distributed systems).
  • Data models for AI systems: Partner with the Platform Lead to design, build, and maintain the data models powering our AI platform - spanning fund and share class data, clickstream interactions, and CRM and finance systems.
  • Alerting and observability: Ensure operational health across all pipelines via structured logging, metrics, DLQ tracking, and purposeful alerting. We view observability as a core engineering practice and will support your growth in designing resilient event-driven systems.
  • Work directly with the analyst team and the data quality team, from requirement through deployment.

What we're looking for:

  • Real dbt experience: You've built and maintained models in a genuine project - incremental logic, tests, an understanding of why downstream consumers matter. It doesn't need to have been enormous; it needs to have been real. BigQuery experience is a plus; another warehouse is fine.
  • Solid Python and SQL skills, with the instinct that code going to production deserves tests.
  • Practical AWS Experience: You have hands-on experience deploying and debugging in AWS. You don't need to know every service we use on day one - we'll teach you our specific stack.
  • Strong CLI Skills: Proficient with terminal-driven workflows, containerized environments, and shell scripting for debugging, automation, and local development.
  • Pragmatic AI Tooling: You leverage AI coding assistants to speed up your workflow, but bring critical oversight to their output - reviewing, testing, and verifying generated code rather than shipping it on faith.
  • Data Intuition & Rigor: You look beyond passing CI/CD checks. When a pipeline runs green but the outputs look off, you dig into the numbers, comparing runs, spotting unexpected anomalies, and validating the business logic behind the data.
  • Accountability & Resilience: You take pride in what you build. You learn from production mistakes, own the outcome, and prefer holding accountability for your own pipelines over handing off maintenance to someone else.
  • Collaborative Communication: You can sit side-by-side with analysts, understand the intent behind their SQL, and partner with them to translate complex business logic into efficient, production-ready solutions.

Nice to Have (Genuinely learnable here - we will train you):

  • Frameworks & Tools: Spark on EMR, Prefect (or experience transferring from Airflow/Dagster), OpenSearch.
  • Architecture: Event-driven design patterns, SurrealDB or graph data stores.
  • Domain Knowledge: Financial services or asset management context.

Company Benefits

  • 25 days annual leave (goes up to 28 after 3 years service, 29 after 4 and 30 after 5 years service)
  • Employee Assistance Programme
  • Well-being Subsidy
  • Pension Scheme
  • Tech scheme plus so much potential to learn and develop within your role
  • Opportunity to work with modern technologies and the opportunity to explore and innovate with new tech
  • We also give you 10% of your working time for your own personal development.

Job Description

Starling is the UK’s first and leading digital bank on a mission to fix banking! Our vision is fast technology, fair service, and honest values. All at the tap of a phone, all the time.

Starling is the UK’s first and leading digital bank on a mission to fix banking! We built a new kind of bank because we knew technology had the power to help people save, spend and manage their money in a new and transformative way.

We’re a fully licensed UK bank with the culture and spirit of a fast-moving, disruptive tech company. We’re a bank, but better: fairer, easier to use and designed to demystify money for everyone. We employ more than 3,000 people across our London, Southampton, Cardiff and Manchester offices.

Our technologists are at the very heart of Starling and enjoy working in a fast-paced environment that is all about building things, creating new stuff, and disruptive technology that keeps us on the cutting edge of fintech. We operate a flat structure to empower you to make decisions regardless of what your primary responsibilities may be, innovation and collaboration will be at the core of everything you do. Help is never far away in our open culture, you will find support in your team and from across the business, we are in this together!

The way to thrive and shine within Starling is to be a self-driven individual and be able to take full ownership of everything around you: From building things, designing, discovering, to sharing knowledge with your colleagues and making sure all processes are efficient and productive to deliver the best possible results for our customers. Our purpose is underpinned by five Starling values: Listen, Keep It Simple, Do The Right Thing, Own It, and Aim For Greatness.

Hybrid Working

We have a Hybrid approach to working here at Starling - our preference is that you're located within a commutable distance of one of our offices so that we're able to interact and collaborate in person. We don't like to mandate how much you visit the office and work from home, that's to be agreed upon between you and your manager.

Our Data Environment

Our Data teams are excited about the value of data within the business, powers our product decisions to improve things for our customers and enhance effective and agile decision making, regardless of what their primary tech stack may be.

We value people being engaged and caring about customers, caring about the code they write and the contribution they make to Starling. People with a broad ability to apply themselves to a multitude of problems and challenges, who can work across teams do great things here at Starling, to continue changing banking for good.

Requirements

We have built our entire banking platform in house and mostly in Java. We are looking for people who want to work on building the tooling that is used by our engineers on a daily basis.

We are looking for people who are truly full stack, and are as comfortable polishing their javascript front end as they are debugging the innards of their java applications database interactions, or standing up infrastructure with terraform. We are looking for people who can:

  • Design REST apis.
  • Code backend services, ideally using Java, or another other server side compiled language.
  • Develop modern front ends, ideally using React and Redux.
  • Get their code into the cloud and support it there, ideally on AWS.
  • Believe in clean coding, simple solutions, automated testing and continuous deployment.
  • Like to take ownership of a feature from the original idea through to live.
  • Think (like us) that a small number of empowered developers is the right way to deliver software.

  • Part-time and/or flexible hours available for most roles

Interview Process

Interviewing is a two way process and we want you to have the time and opportunity to get to know us, as much as we are getting to know you!

  • Stage 1 - 30 mins with one of the team
  • Stage 2 - Take home challenge
  • Stage 3 - 90 mins technical interview with two team members
