Job Description

We're looking for a Principal Engineer to join Masabi's Architecture team.

This is a senior role for someone who combines deep technical expertise with strong judgement and the ability to operate across teams. You'll help shape the technical direction of Masabi's platform while staying close enough to the detail to design, review and deliver meaningful technical work.

Working across the engineering organisation, you'll act as a senior technical leader: defining and evolving architecture, guiding complex decisions, and contributing hands-on where it matters most. A particular focus for this role is strengthening our data architecture, how we structure, use and build on the data our platform generates.

The role suits someone who can move between system-level thinking and implementation, someone who understands trade-offs, can navigate ambiguity, and helps turn complex or loosely defined problems into clear, practical technical approaches.


Responsibilities

  • Shape Masabi's platform architecture, including platform blueprint definition, standards and best practices
  • Help shape Masabi's data architecture and strategy, including how we structure, store and make use of the data generated across our platform
  • Design and deliver scalable, robust, cost efficient services aligned with platform blueprint
  • Stay hands-on in code and technical delivery, including reviews and targeted contributions
  • Identify and work through complex platform challenges related to scalability, performance, resilience and cost
  • Act as a senior technical advisor across engineering teams, supporting and influencing technical decisions and ensuring Masabi standards are followed
  • Shape and contribute to technical roadmap planning and prioritisation of platform improvements
  • Support RFP estimation and technical scoping for complex initiatives
  • Produce clear, high-quality technical documentation and architecture artefacts
  • Improve how architecture is understood and applied across engineering and the wider business
  • Contribute to and help shape technical forums and working groups, including areas such as API and architecture governance

About You

  • You bring strong experience designing and evolving distributed systems and microservices architectures
  • You've operated at Principal or Staff level, shaping technical direction across multiple teams or domains
  • You are comfortable staying hands-on, contributing in code, design and delivery when needed
  • You have strong experience with cloud platforms (AWS preferred) and modern infrastructure practices
  • You've worked on systems where scale, reliability, performance and cost trade-offs matter, and can navigate those decisions thoughtfully
  • You have proven experience in data architecture (e.g. data platforms, pipelines, warehousing or data lakes) and working on products built on top of large data stores
  • You can take loosely defined (early stage) business or technical problems and turn them into clear, actionable technical approaches
  • You communicate complex ideas clearly and effectively, and produce structured documentation that helps both technical and non-technical audiences make decisions
  • You've contributed to engineering standards, architecture patterns or platform direction
  • Strong experience with REST API design in complex, multi-service environments, ideally including how APIs are consumed on the front end
  • Interest in or exposure to AI-enabled systems, particularly understanding architectural implications in production

Nice To Have

  • Experience breaking monolithic applications into microservices architectures
  • Experience with event-driven architectures (e.g. Kafka, schema governance)
  • Experience improving cloud cost and system efficiency at scale
  • Familiarity with a range of tools and technologies including:
  • Development: Kotlin, Java
  • Data storage/processing: DynamoDB, MySQL, Snowflake, Databricks, Spark
  • Infrastructure as code and CI/CD: Terraform, GitLab CI/CD

Company Benefits

  • Hybrid or fully remote working model
  • 25 days of holiday per year plus the option to buy another 5 days pro-rated
  • Private Healthcare via AXA including pre-existing conditions and mental health
  • Life Insurance
  • Choice of workstation
  • Flexibility to work from home whenever you need to and flexible working hours (we are currently operating either fully remote or in a hybrid mode, please see Remote Working Policy below for more details)
  • Ability to work for up to 3 months per year from any country in the world
  • Pension scheme
  • Training allowance of up to £1000 per year
  • £200 annual allowance for any home office need or improvement
  • Onsite/video yoga classes
  • Childcare vouchers
  • Cycle to work scheme
  • Unlimited snacks and drinks, with regular free lunches (when in the office)
  • Regular social gatherings with a monthly allowance for each employee
  • Biannual company events
  • Fun and collaborative environment with a focus on making a difference in the world

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

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.
