Senior Backend Engineer (Node.js)

About the company

Emma is the app to manage all things money. Our mission is to empower millions of people to live a better and more fulfilling financial life. Emma was founded by engineers, who are extremely focused on coding, product and data. These are the three pillars on which we want to build a strong tech culture and fix personal finance once for all. We have raised more than $8m+ to date to build the one stop shop for all your financial life.

At Emma, we are:

• Bold
• Determined
• Focused
• Autonomous

We are a high-performance team and we run the company like a professional sports team. We expect each and every team member to move fast, have ownership over their work and hold each other to a high standard. If you're not driven to own your work, execute swiftly, and innovate constantly, this isn't the right place for you.

About the role

Responsibilities

You will work directly with the CTO and your focus will span different areas, with challenges related to our backend infrastructure, from scaling challenges to data processing ones. We have an intense roadmap ahead, which includes a plethora of new features and integrations, which you will be part of.

Our tech stack:

• Languages: TypeScript, Javascript
• Libraries and frameworks: gRPC, Redux, React Native, Next.js
• Datastores: Vitess, MySQL, CockroachDB, BigQuery, Redis
• Infrastructure: Google Cloud Platform, Kubernetes, Docker, PubSub, Terraform
• Monitoring: Grafana, Prometheus, Sentry, Metabase

Some of our current interests lie in:

• Product: We are building the 1st Finance App in the UK, used by many people every day. We are shipping an average of a feature per week and tons of micro‑improvements that compound in making our app valuable.
• Machine learning: we have an enormous amount of transaction data, which we are using to provide better insights to our users. Predicting when a user is going in overdraft, when a card payment is coming through or clustering a huge set of subscriptions are a few of the problems we are tackling.
• Scaling: our services are used by millions of people. We need to keep Emma up and running smoothly. This means an intense effort and quality in the work we do.
• Speed: In the hyper‑competitive FinTech industry what really matters is speed.
