Job Description

The Senior Data Engineer exists to build and scale the data infrastructure that powers Kargo's targeting, identity, and measurement capabilities. This role owns hands-on implementation of the pipelines, systems, and tooling that turn raw data into competitive advantage — at speed and at scale. When this role is firing, data flows reliably, engineering teams move faster, and Kargo's data products are built on a foundation that can handle whatever comes next.
This is a remote role in London, UK.


Outcomes — What Success Looks Like in 6–12 Months

  • Core ETL/ELT pipelines are optimized and operationally reliable — Existing pipelines are assessed, bottlenecks are addressed, and data flows with documented SLAs; incidents are caught proactively, not reactively
  • New datasets are onboarded and powering targeting capabilities — At least one meaningful new data source is integrated end-to-end, with targeting or measurement use cases activated and performing against defined KPIs
  • CI/CD practices are adopted and accelerating team velocity — ArgoCD-based deployment pipelines are in place and the team is shipping with greater speed and fewer rollback events as a result
  • Privacy-compliant data methodologies are implemented and documented — Modern approaches to identity and targeting that meet GDPR/CCPA standards are built into the stack, not bolted on after the fact
  • Technical documentation is thorough and actually used — Implementation docs, runbooks, and best practices are written clearly enough that a new engineer can onboard to a system without a walkthrough

Skills — Core Technical Capabilities

  • Deep proficiency in Python and Spark for building and optimizing large-scale data pipelines; strong grasp of data structuring for performance and efficiency
  • Hands-on experience with Airflow for orchestrating complex data workflows, and Apache Iceberg for table format management at scale
  • Extensive AWS experience including EKS, Docker, and Kubernetes; comfortable owning infrastructure deployment and scaling decisions
  • CI/CD fluency — ArgoCD, automated testing pipelines, and monitoring via Prometheus; treats deployment reliability as a first-class concern
  • Familiarity with analytical warehousing in Snowflake or ClickHouse — SQL optimization, cost management, and performance tuning
  • Working knowledge of identity, privacy, and targeting methodologies in ad tech — understands how data flows through the ecosystem and where privacy constraints apply

Preferred

  • Experience with real-time streaming technologies — Kafka, Flink — for latency-sensitive data processing use cases
  • Familiarity with Aerospike or similar low-latency key-value stores used in high-throughput targeting systems

Competencies — Behaviors We Like to See

  • Hands-On Ownership
    • Drives implementation independently from ambiguous brief to working system — doesn't wait for perfect specs to start building
    • Takes operational responsibility for the systems they build; monitors, iterates, and improves without being prompted
  • Rigorous Problem-Solving
    • Brings structured thinking to complex, multi-system challenges; breaks down problems clearly before reaching for a solution
    • Optimizes for the right outcome — performance, cost, reliability — not just the fastest path to "done"
  • Technical Collaboration
    • Contributes actively in design and brainstorming sessions; brings strong opinions and is equally willing to update them when better ideas emerge
    • Communicates technical decisions clearly to both engineering peers and non-technical stakeholders without oversimplifying
  • Documentation and Knowledge Sharing
    • Writes documentation that actually gets used — clear, thorough, and maintained as systems evolve
    • Treats onboarding others as part of the job; leaves systems better understood than they found them

Company Benefits

  • Flexible holidays - We give you an extra day of leave for every year of service (up to a maximum of 5) and we believe you should take time off when you need it. We also give our staff three paid company days off: Good Friday, Christmas Eve & New Years Eve.
  • 13 weeks of paid maternity leave & one week of paid paternity leave (after 1 years service)- Happy Fridays: every other Friday you get half day off.
  • A Macbook will be provided before you start and we provide a stipend to allow you to create the remote, WFH tech setup you need to be successful.

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. Hear from the team in our latest blogs or our case studies with Women in Tech.

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.

Company Benefits

  • 33 days holiday (including flexible bank holidays)
  • An extra day’s holiday for your birthday
  • 16 hours paid volunteering time a year
  • Part-time and/or flexible hours available for most roles

  • Access to initiatives like Cycle to Work, Salary Sacrificed Gym partnerships and Electric Vehicle (EV) leasing

Full details are available on our careers site

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! Our interviews are conversational and we want to get the best from you, so come with questions and be curious. In general you can expect the below, following a chat with one of our Talent Team:

  • Stage 1 - 30 mins with one of the team
  • Stage 2 - Take home challenge
  • Stage 3 - 90 mins technical interview with two team members
  • Stage 3 - 45 min final with an executive and a member of the people team
