Full Stack Engineer

  • Full Stack

  • London, UK

Braid is seeking talented full-stack and iOS engineers for an early-stage start-up in the Open Banking and Digital Identity space. We’re currently focused on mid-level engineers, but will be looking to hire / appoint a head of engineering at some point soon (we currently have a highly experienced CTO leading the team). This is a unique opportunity to develop and grow your career by having direct access to and mentorship from an outstanding leadership team (including ex-Mckinsey, ex-Revolut, ex-PwC, and a current Cambridge professor), and to be part of the whole product development process.

This is truly an opportunity to make a genuine difference to a whole lot of peoples’ lives… if you know anyone suffering under credit card debt, or who couldn’t get a mortgage or car loan because of past mistakes then you’ll know what we mean.

About Braid

Braid is an early-stage start-up in the Open Banking and Digital Identity space.

We’re building a personal financial operating system via a smartphone. The service combines information from users’ different bank accounts, credit cards, mortgages, investment accounts, and other financial products, and helps them optimise their finances. We provide guidance, tips, and suggestions on how to avoid tricks and traps set by banks or credit card companies, and automate money management to help users reach their financial objectives faster – whether that be sticking to a budget, paying down debt, or saving for a holiday.

In the future, Braid will also give the user the ability to prove their identity in a streamlined way. This will minimise the effort required to sign up for a new service, log into online accounts, sign e-documents, approve transactions, prove age or address, or confirm receipt of a delivery.

This is an opportunity to get in on the ground floor with a business that has a super-ambitious business model (this will never be a £20 million company, it’s unicorn or bust!). We’ve just completed a pre-seed funding in the summer of 2021 and intend to launch a beta version of our product in the coming months.

About you

The ideal candidate will have 4+ years experience building innovative products that are completely new to the world – we’re not looking to replicate anything that’s already out there.

We are seeking the type of person who wants to make an impact through disruptive ideas and bold innovations, by being an individual contributor and a key team player.

That said, as we are a fintech provider regulated by the FCA, security will be key – you’ll need a strong understanding of current security protection measures as well as be able to think outside the box to predict what future threats might emerge.

From a technical perspective, experience with the following would be highly preferred and beneficial:

Mobile development

  • Cross platform mobile development experience (i.e. Flutter)

  • Ability to convert Figma prototype to mobile application

  • Experience of mobile device security

  • GraphQL and Rest services integration

  • AppStore deployment experience

Platform development

  • Native cloud development experience (i.e. GCP, AWS, Azure), specifically notification frameworks, serverless containers, GraphQL and Rest services

  • Applied application security using JWT, OAuth, key management, verification and encryption

  • Database and NoSQL experience with Postgres and Redis


  • Kotlin and Dart

Tools and frameworks

  • Spring Boot with exposure to wider ecosystem

  • Building Docker service images

  • DevOps i.e., CI/CD pipeline deployments on Gitlab or GitHub

Test development

  • Test driven development skills (i.e., JUnit, Mockito)

Other technical skills (“nice to have”)

  • Scaling services using Kubernetes

  • Experience of Behaviour Driven Development testing (i.e., cucumber.io, Appium)

  • Code quality tools i.e., SonarCube

  • Terraform IaaS deployment

Some personal qualities we’re looking for:

Comfort with ambiguity

  • As an early-stage start-up creating a new-to-the-world proposition, ambiguity and uncertainty is a given; if you haven't read The Lean Startup then now would be a good time

Passion to do good

  • Our business has a strong social element, focused on financial well-being and inclusivity - if this doesn't excite you, it's unlikely you will excite us

Intellectual horsepower

  • A degree from a top university isn't necessary, but will be a good indicator that you have the intellectual heft we're seeking. Most importantly, we want you to be excited about the opportunity to navigate some highly complex topics

What we offer

We’re building a culture that reflects the changing world, changing values, and changing expectations around the role work plays in your life; flexible working is a given, and we’re closely monitoring the success of 4-day work week trials. Here are some key terms of employment we can offer:

  • A competitive salary

  • Meaningful equity grant

  • Centrally located HQ in Canary Wharf, London

  • 25 days of holiday per year excluding bank holidays

  • Pension scheme

  • Company happy hours

  • Weekly team happy hours

  • Membership to Level 39
