Senior Backend Engineer

About us

We are a small, self-funded team building a booking app for independent salons and tattoo studios. Two developers, a designer and a support lead make up most of the company, so everyone touches the product.

The role

The previous person in this role moved to another team. The operations team owns services that process several million requests a day. We need another engineer who is comfortable owning them in production. Our headquarters is in Marseille, and about a third of the team works remotely from other countries. This is a long-term contractor role, paid monthly in USD. Core hours are 10:00 to 15:00 CET.

In your first few months you will

• Design and build REST and gRPC APIs in Go, Java or Python
• Containerize services with Docker and deploy them to Kubernetes or ECS
• Coordinate with frontend and mobile engineers on API contracts and versioning
• Implement background jobs and event consumers using Kafka, SQS or RabbitMQ
• Model data and write migrations for PostgreSQL, MySQL or DynamoDB
• Write integration and contract tests so API changes don't break consumers
• Review code for correctness, performance and failure handling

What you bring

• Proficiency in at least one of Go, Java, Kotlin, Python, C# or Node.js
• Hands-on experience with AWS, GCP or Azure services
• Working knowledge of message queues or streaming platforms
• Clear written communication, including design docs
