Job Description

As a Backend Engineer, you will have the opportunity to collaborate as a member of one of our international cross-functional product teams and engage with a complex product that challenges your technical and organizational skills, fostering personal growth. With the collective expertise of over 160 years within our team, you'll have access to a wealth of knowledge and experience to guide you in finding optimal solutions and implementations. Responsibilities include refining feature requirements architecture, implementing, deploying, and tracking their usage and impact on the system.

Our stack

Our stack began as a monolithic MVC application using Microsoft technologies. Motivated by user growth and increased complexity of features our platform has evolved. We've adopted an event-driven, scalable, dockerized microservice architecture, leveraging technologies like .NET, MS SQL Server, MongoDB, Elasticsearch, Angular, and various third-party products and services. We now run on 36 services and 33 consumers and integrate with 10+ third-party systems.

Our platform experiences heavy usage 24/7, presenting numerous performance and workload isolation challenges that we actively address. This is why we focus on scalability and reliability leveraging microservice architecture and feature flags to reduce deployment risk and prevent incidents.

To help us in the process, we cover new changes with unit, integration and E2E tests. This approach allows us to seamlessly upgrade our stack to the latest version. We deploy frequently in small iterations using our one-click CI/CD pipeline.

At Repsly, we place a strong emphasis on ownership and engagement. We utilize Scrum to effectively organize and enhance our processes, alongside OKRs to ensure alignment across the company at all levels
