SG - Backend Engineer
Experience: 3 years+
CTC: $6,000 - 8,000
Job Location: Singapore


Do you have a product-first approach when building software? Are you experienced with backend development and constantly finding ways to improve existing infrastructure, platforms, and frameworks? Do you enjoy working in an entrepreneurial environment with a talented, fun and energetic team who is running at full speed to redefine the way people invest?

We are currently expanding and looking for a motivated Backend Engineer who have a passion for building robust and scalable systems for customer-focused financial products.

You are responsible for translating high-level business requirements for new products and features into the services and data models that power them. You will work to design, build, and support many of the core systems powering StashAway's financial software, from cash flow and transaction libraries to our financial computation engine, You like thinking critically about how to architect and build new components in a performant and scalable manner.

You will need to leverage the entire technology stack to realise these goals, and will be part of a team that is constantly tackling difficult questions of scale, architecture and interaction. You will develop experience with the full stack across different backend systems, restructuring existing systems, extending their functionality as well as building entirely new services from the ground up in the area of Operations, Compliance, Trading and Banking.

Your contribution to a dynamic Technology team allows you to be exposed to a variety of concepts and technologies. You will enjoy being able to have a direct impact on StashAway's internationalisation plans, and the development of features and new investment products.

We have assembled an agile stack of microservices primarily written in Scala, Kotlin, Python, Go, and JavaScript that is organised in Kubernetes and runs on AWS, communicates via Kafka and persists data in Cassandra, MongoDB, and Postgres databases. We heavily utilise Event Sourcing as a data modelling and persistency concept for our core trading system.

We strive to keep most of the services simple and robust so they are easy to develop, test and maintain allowing us to iterate quickly and productively.
