Description du poste

We're making the world of digital assets accessible and secure for everyone.

Join the mission.

Founded in 2014, Ledger is the global platform for digital assets and Web3. Over 20% of the world's crypto assets are secured through our Ledger Nanos. Headquartered in Paris and Vierzon, with offices in UK, US, Switzerland and Singapore, Ledger has a team of more than 500 professionals developing a variety of products and services to enable individuals and companies to securely buy, store, swap, grow and manage crypto assets - including the Ledger hardware wallets line with more than 6 millions units already sold in 200 countries.

At Ledger, we embody the values that make us unique: Pragmatism, Audacity, Commitment, Trust and Transparency. Hear from our employees how they shape the work we do here.

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.

Your mission

• Build highly available, consistent, and well-functioning services to power Ledger's products
• Leverage all the power of functional programming with Scala and the Typelevel stack
• Dive into cryptocurrencies protocols internals
• 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

What we're looking for:

• 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...)

What's in it for you?

• Equity: Employees are the foundation of our success, and we award stock options so you can share in that success as we grow
• Flexibility: A hybrid work policy
• Social: Frequent social events, snacks and drinks
• Medical: Comprehensive health insurance policy offering extensive medical, dental and vision care coverage
• Well-being: Personal development, coaching & fitness with our dedicated partners
• Vacation: Five weeks of paid leave per year, in addition to national holidays and rest & relaxation (RTT) days
• High tech: Access to high performance office equipment and gadgets, including Apple products
• Transport: Ledger reimburses part of your preferred means of transportation
• Discounts: Employee discount on all our products.

We are an equal opportunity employer for all without any distinction of gender, ethnicity, religion, sexual orientation, social status, disability or age.
