Job Description

Mobile is the front door to the Q-ID. Every authentication, whether it's a customs officer scanning a tax stamp, a partner embedding Q-ID verification into their own app, or a consumer checking a product is genuine, happens on a smartphone. These authentications happen in variable real-world conditions, on a wide range of devices. We are looking for a hands-on engineering leader to own that surface end-to-end.

The Lead Mobile Engineer will be responsible for leading and managing the mobile engineering team, with a tech stack spanning (in order of importance):

  • Native iOS (Swift, SwiftUI, AVFoundation, Core ML, Vision)
  • Native Android (Kotlin, Jetpack Compose, CameraX, ML Kit, TensorFlow Lite)
  • Computer vision and on-device ML for Q-ID authentication
  • Mobile SDK design and distribution, for partners embedding Q-ID into their own apps
  • Cross platform integrations like .NET MAUI
  • Integration with our AWS verification APIs

This is a senior leadership position for someone who is still in the code day-to-day. Q-ID authentication is a computer-vision problem running on a consumer device in unpredictable lighting, on substrates ranging from paper tax stamps to gold blister packs. Small mobile improvements (scan speed, false-reject rate, camera handling) have outsized commercial impact and are often the difference between winning and losing a customer. The role is varied and includes:


Strategic Leadership

  • Own the technical direction for mobile at Quantum Base.
  • Help define roadmaps that align with the commercial pipeline .
  • Set the bar for scan performance, reliability and device coverage.
  • Build a culture of fast iteration, measured against real scan data, not just unit tests.
  • Encourage the use of modern best practices and AI tooling

Team Management

  • Lead, mentor and grow the mobile engineering team.
  • Recruit and retain strong mobile talent; build a team that is comfortable working alongside physicists, mathematicians and ML specialists.
  • Partner closely with the cloud team, R&D team and the commercial team.

Technical Oversight

  • Be hands-on across complex mobile problems - camera pipelines, image preprocessing, on-device inference, SDK packaging, app-store release engineering.
  • Raise the engineering bar on code quality, automated testing (including on-device and real-substrate testing), CI/CD for mobile, crash and performance monitoring.
  • Own the mobile SDK contract with partners.
  • Work with product, design, algorithms and customer implementation to turn scan performance requirements into shippable releases.
  • Represent mobile in customer-facing technical conversations, including with security printers and government programmes where reliability expectations are high.

Key Experience

  • 8+ years in mobile software engineering, with at least 3 years leading teams.
  • Deep, hands-on expertise in both native iOS (Swift) and native Android (Kotlin).
  • Experience with camera, computer vision and on-device ML on mobile (Core ML / Vision / ML Kit / TensorFlow Lite, or equivalent).
  • Experience designing and shipping a mobile SDK consumed by third-party developers.
  • Strong engineering fundamentals (SOLID, TDD, clean architecture) and a pragmatic view of when to apply them.
  • Solid understanding of Agile and DevOps practices as they apply to mobile (CI/CD, release trains, staged rollouts, crash and performance analytics).
  • Track record of working with cloud-backed mobile products and integrating with REST APIs on AWS or equivalent.
  • Excellent communication and leadership skills, and comfort in front of customers.
  • Expert with modern AI tooling

Nice To Have Experience

  • A background in science, especially physics or mathematics.
  • Background in computer vision, image processing or applied ML.

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.

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
