How We Build

At Synctera, engineers play a hands-on role in building and evolving our core platform. With smaller teams and fewer layers, engineers have real ownership over their work, move quickly from idea to execution, and contribute directly to technical decisions that matter.

You’ll work on internal systems that must be reliable, secure, and scalable, while helping shape how the platform continues to grow and mature. It’s an environment designed for engineers who enjoy meaningful impact, autonomy, and solving complex problems in a regulated, real-world context.

Our Stack

Our platform is built in Go (for backend services) and React with Typescript (for the Synctera Console, our frontend). We’re built on top of Google Cloud Platform and typically use Postgres (Cloud SQL, AlloyDB), Redis (Cloud Memorystore), and Pub/Sub as our core application stack, with OpenAPI specifications being used to both document our API and be the foundation for inter-service communication.

Our infrastructure is predominantly a mixture of Kubernetes (Google Kubernetes Engine) and Cloud Run (Google’s serverless compute platform), with Terraform orchestrating infrastructure, and tools like Argo facilitating deployments.
