Backend Engineer

In a nutshell.

We're looking for an enthusiastic person to join our team as a backend engineer. You'll contribute to our core API, microservices architecture, and cloud infrastructure that powers our platform. You'll make an impact for hundreds of thousands of users daily by building and maintaining the robust backend systems and infrastructure that drive our applications.

The role.

As a backend engineer within Check, you'll be responsible for developing and maintaining the APIs, DevOps, microservices, and cloud infrastructure that form the backbone of our platform. Our entire platform was built from the ground up in recent years with modern technologies. You will be working side-by-side with a team of enthusiastic (in-house) developers who bring years of experience to the table.

Our tech stack.

The backend systems you'll be working on are built primarily in Python, with our main API serving as the central heart of our platform. We also run several microservices written in Rust for performance-critical operations like real-time fleet updates, and a specialised H3 service for advanced geographic features. Our data is stored in PostgreSQL databases, and we leverage Clickhouse as our data warehouse. We use kafka for streaming events and telemetry.

All backend code follows modern development practices, allowing us to maintain a scalable platform and move fast while ensuring reliability. The customer-facing apps are written in Swift and Kotlin, making them native to iOS and Android respectively, while our internal tools use Next.js and React.

Everything is containerized with Docker and orchestrated through Kubernetes clusters, with Helm as our package manager. We manage our infrastructure in-house, running two Kubernetes clusters that support our entire platform.
