Job Description

Prolific is not just another player in the AI space – we are the architects of the human data infrastructure that's reshaping the landscape of AI development. In a world where foundational AI technologies are increasingly commoditised, it's the quality and diversity of human-generated data that truly differentiates products and models.

The role

We’re looking for Senior Product Engineers with a ‘product builder’ mind-set to join our team and take a pivotal role in the development and guidance of our product. As a ‘t-shaped’ engineer, you will bring a broad practical knowledge across various areas of software development, complementing and supporting our growing team whilst likely having a deeper specialism in front or backend. This is an exciting opportunity to leverage your existing skills, experience, and knowledge to significantly influence the trajectory of our product as we aim to revolutionise research.

What you’ll bring to the role

  • Deep understanding of modern web applications
  • Experience building Typescript/Javascript applications and using NoSQL databases
  • Experience using Python, or similar language
  • Knowledge of Event-Driven Architecture
  • Experience using AWS (Serverless) and/or GCP
  • Understand the importance of driving quality into code through test automation
  • Have supported applications in production, with demonstrable experience of good observability practices within a full stack environment. (e.g. Rum, Tracing)
  • Have worked in a collaborative environment with strong engineering practices and know what good engineering looks like
  • Care about the product life cycle and are customer value focused
  • Understand the value of continuous, iterative improvement using data to drive decisions and a culture of feedback
  • Passionate about software development with an appetite for learning and self-improvement

What you’ll be doing in the role

  • As a member of a cross-functional, stream-aligned team, you will work collaboratively with the teams’ engineering manager, product manager, designer, and up to 4-5 other engineers, including a tech lead
  • Using agile software development practices and a product mindset, you will work as a team to plan, build and support software that our customers love
  • You will be highly self-motivated and energetic and enjoy working in a fast-paced environment with a bias for action
  • Collaborating with teams outside of product engineering, working closely with customers and understanding their needs
  • Be happy working in all the major cloud providers: AWS, GCP&Azure
  • With a You Build It, You Run It mindset, you will have intimate knowledge of our products from code commit through to production operation
  • Supporting production systems with monitoring tools such as Datadog
  • Strive for stable systems observability
  • You will champion our principles, fuel a growth mindset by getting involved in communities and help improve our engineering culture
  • Pushing the boundaries, questioning the status quo, ensuring what we are doing and what we are building has high value and impact for our users

Key Technologies

  • Cloud Platforms: Google Cloud Platform and AWS
  • Programming Languages: Python, JavaScript, and TypeScript
  • Frameworks: Vue.js, Django Rest Framework, Container-based and Serverless architectures
  • Databases: MongoDB and DynamoDB
  • DevOps and Monitoring: CircleCI, GitHub Actions, Kubernetes, Celery, EventBridge and DataDog

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 are looking for talented data professionals at all levels to join the team. 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
  • Salary sacrifice, company enhanced pension scheme
  • Life insurance at 4x your salary
  • Hybrid/remote working
  • Private Medical Insurance with VitalityHealth including mental health support and cancer care. Partner benefits include discounts with Waitrose, Mr&Mrs Smith and Peloton
  • Generous family-friendly policies
  • Varied social groups set up and run by our employees
  • Perkbox membership giving access to retail discounts, a wellness platform for physical and mental health, and weekly free and boosted perks
  • 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
