Job description


Our main language is Rust and we have a few legacy NodeJS (Typescript & Javascript) servers. All our services run in Dockers hosted in the Cloud, and we are working to be compatible with different providers (AWS, GCP, Azure, etc.). We develop using the Agile process with the help of Github and Notion for ticket management. We follow Google coding best practices (Mono-repo, micro-services, etc). You don’t need to know how to code in Rust but only the willingness to learn it!

We are looking for someone tenacious & quick-learner, to learn and use these various technologies (no pre-requisite required). Here is a few of them:


• Coding new integrations (Scrapers, File parsing, API branching, etc)
• Fixing integrations
• Improve the existing libraries through new features

Tech Tickets
• Update partner configuration
• Debugging
• Technical Support

Thanks to these two missions you will be able to develop your communication skills and your business sense.

Small features
• Proposing feature requests
• Implementing new features


Tackling an international market in a fast growing startup, you’ll have three main challenges:

Complexity: a lot can happen in an e-commerce transaction, specially when you connect multiple players.
Performance: Stockly manages tens of millions of articles, that’s a hell of a lot of web requests per day.
Scalability: Being focus of growth, we require that published code still work with ten times more volume.
