Choco

What you will do

Here at Choco, we like to use the space shuttle as a metaphor for our engineering work. Now, you will join and help us bring the shuttle to the moon. We are just launching several new cross-functional teams focusing on implementing business-critical product features and all related functionalities across our mobile and web platforms. You will take end to end ownership for delivering the solution, ensuring it is performant, secure, compliant and stable. We will rely on your technical expertise, architecture skills and mentoring abilities to move both the product and the team closer to our goals. 

Our working model reflects a balance between the highly collaborative nature of our business and modern-day flexibility. As a part of our Product Engineering team, we look forward to seeing you in our Berlin office at least 3 days a week.

On a daily basis, you will: 

• Work with our backend team to enhance its event-driven microservice architecture inside of the AWS-ecosystem in order to help our web and mobile products give the best experience to its users. 
• Work on our API layer, which utilizes Amazon’s managed GraphQL service called AppSync - one of Amazon’s latest technologies.
• Continuously contribute to our TypeScript codebase to improve our code base, systems and processes.
• Architect services using DDD principles and patterns to allow autonomous development and future scaling.
• Operate and maintain the services your team owns in order to meet our user's expectations
• Share your knowledge, develop expertise in our product and grow with your team to become an even greater engineer.

Our tech stack in Backend Engineering

We have a cutting-edge environment and use NodeJS and TypeScript in combination with NestJS framework, GraphQL, AWS DynamoDB and PostgresQL. Our infrastructure is powered by various AWS serverless technologies such as SNS,SQS,Lambda, and AppSync.. We are also actively investing in our containerized architecture with EKS (Kubernetes). For infrastructure management we use AWS CDK and Helm.

What you will need to have an impact with us:

• 5+ years experience as a backend developer, ideally with NodeJS and production experience in TypeScript
• Experience with high load microservices, event-driven architecture, integrations and developing APIs
• Proven experience writing clean code, applying design patterns and creating scalable, and maintainable code
• Strong knowledge in system designs and software architectures
• Experience using system monitoring tools (e.g. Datadog) and automated testing frameworks
• Ability to drive and deliver large features and projects in an agile environment
• Strong communication skills combined with influence and eagerness to share and develop others. Good learning ability, open-mindedness and good self-organizational skills will be absolutely key to the success of your work and the business overall. 

You will impress us even more if you have

• Experience being a part of or driving complex refactorings within or beyond the team boundaries
• Experience working with large GraphQL schemas following best practices
• Experience working with Lambda functions and serverless architecture
• Experience working with and applying DDD patterns in practice
• Experience building real-time communication services

We invite you to take part in the following selection process:

• Introduction call: a Tech Recruiter will tell you more about Choco, our Tech Org and get to know your work, background, interests and you as a person better.
• Hiring Manager interview: You will meet your potential manager and discuss the mission, challenges and goals of the team. We would like to see how you collaborate on building the most amazing product for your customers
• Pair Programming Interview: during this stage we want to get deeper into your technical knowledge. Next to some technical questions you will work together with another engineer in a pair programming exercise.
• System Design Interview: Together with our engineers you will do a system design exercise to test your skills (whiteboard session).
• Culture interview: You will meet other engineering leaders to discuss about the Choco culture and your non-technical contribution to Choco
