The team

You will join the backend services team which is in charge of building services that power Ledger products.

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. Customer-focused, they are also eager to understand and implement product and business requirements.

We are convinced that being an engineer is also taking time to challenge, discuss and share what we are working on. A dynamic roll over each service allows every team member to get involved in many projects over time. We take time each month to have a dedicated knowledge-sharing meeting and participate actively in the Scala community (Meetups, Conferences, etc…).

• Build highly available, consistent, and performant services to power Ledger’s products

• Integrate and consolidate off-chain data coming from several API sources

• Leverage all the power of functional programming with Scala and the Typelevel stack

• Maintain tools and services in a diverse stack (Scala, Python)

• 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 systems to detect unexpected failures/behavior

• Use CI / CD to deploy and secure workflows

What we're looking for

• First relevant experience in backend robust development

• Scala, Haskell, or functional programming experience is nice to have

• Node.js and Java developers who are willing to dive into Scala technologies are welcome

• Enthusiastic about teamwork, learning, and teaching (meet-ups, hackathons, training…)

• Adaptability to do teamwork in a fast-evolving environment

• You are autonomous, proactive, and capable of self-training

• Having an interest in cryptocurrencies and wishing to work with blockchain technology is a real plus
