Original job description

About Quartz

Quartz is reimagining wealth management through personalised intelligence. It's the first wealth platform that truly learns from you, understands your goals, and helps you make confident, informed decisions all in one secure platform. Get the experience of a personal banker that works with you 24/7, at a fraction of the cost.

About The Role

We're looking for a Backend Engineer to help build the core of how Quartz works - the systems that aggregate user data, power Charlie (our AI advisor), and make personalised wealth advice possible at scale.

You'll write Kotlin day-to-day, work across greenfield services and existing systems, and make the kind of early engineering decisions that compound for years. Expect to partner closely with the Head of Engineering on architecture, and with product and ML on how the backend shapes what users experience.

This role is for someone who excels at first principle thinking, is comfortable owning systems end-to-end, and moves with the urgency of a startup while holding the rigour a financial platform demands. If you're looking to do meaningful work and you're not driven by a nine to five mentality, you might be just who we're looking for.

Our technology stack

Kotlin
SpringBoot, Arrow
PostgreSQL
JUnit, Mockk, Springmockk

What you'll be doing

Designing and building the APIs and services that power Quartz's mobile and web apps
Building the data infrastructure that aggregates user accounts and feeds Charlie, our AI advisor
Owning features end-to-end - from API design through to production rollout and observability
Partnering with ML and product to translate advisory logic into reliable, testable backend behaviour
Setting the bar on code quality, testing, and engineering rigour alongside the Head of Engineering

What you'll need

Fluency with Kotlin or Java
5+ years of experience in backend development
To be a quick learner with an ambitious attitude and results-driven personality
Experience in a start-up or scale-up (at least have started something as a side project!)
Fluency in English

Nice to have

Experience in finance
Experience in a product-focused environment
Experience in DevOps
Experience working with Hexagonal Architecture and DDD

More about this job

Responsibilities

Design and build APIs, backend services, and data infrastructure for Quartz's apps and AI advisor, owning features from design through production rollout and observability. Collaborate with engineering leadership, product, and machine learning teams to shape architecture and deliver reliable, testable backend behavior.

Requirements

Requires fluency in Kotlin or Java and at least five years of backend development experience, along with English fluency. The ideal candidate is an ambitious, quick learner with startup or side-project experience; finance, product-focused environments, DevOps, Hexagonal Architecture, and DDD are advantageous.
