Job Description:

You will join the Cloud Wallet team which is in charge of building and maintaining backend services to manage crypto wallets on server side, used by our B2B and B2C products. Our team is working closely with our other backend teams, such as the Backend Blockchain team that builds blockchain indexers we rely on. The team is composed of passionate engineers who believe in the benefits and strength of functional programming to develop robust and scalable platforms and APIs, while also being eager to understand and implement product and business requirements. We use Scala extensively to build our backend services and tooling, but not only that: TypeScript/node.js is also an integral part of our tech stack.

Job Responsibility:

Conduct benchmarks to identify bottlenecks and optimize the overall performance of our services
Deliver a high-quality piece of software (Test it, Document it, Demonstrate it)
Design monitoring and alerting systems to detect unexpected failures/behavior
Use CI/CD to deploy and secure workflows

Requirements:

Demonstrable experience and knowledge of backend services programming
An interest in working in a polyglot environment (Scala experience is not mandatory, but a real plus)
Knowledge of relational databases and SQL (we use Postgres)
Knowledge of Linux operating systems
Adaptability to work within a team in an evolving environment: You are autonomous, proactive, and able to upskill in certain areas yourself where necessary
Experience with continuous integration/deployment solutions
Knowledge of containerization and cloud deployments
An interest in cryptocurrencies and wishing to work with blockchain technology is a real plus
Enthusiastic about teamwork, learning, and teaching (meet-ups, hackathons, training…)

Nice to have:
