Descriptif du poste

🔎 In a nutshell, what are we looking for?

We are looking for a smart and talented end of studies intern to join our amazing Tech team. (e.g. Oscar, Thomas,Camille,Sylvain). Due to our strong growth, this number is likely to increase quite rapidly.


Our main language is Rust and run in Dockers hosted in the Cloud, and we are working to be compatible with different providers (AWS, Heroku, 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).

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:


There are several Tech teams at Stockly, here are some examples of what what they do:

Engine Team

Engine developers are those working on the primary services of Stockly, most of the time they build APIs for other Stockly services. Their work consists into the modelisation of complex situations (billing, operations, stocks, etc).

• Build new features in core services as Operations & Stocks (ex. Delivery Disputes, Product Pages, etc)

• Maintain core libraries (diesel, grpc, http-client, internal-error, etc)

• Build new core services (Auths, Retailers)

Meet Sylvain, talking about the Engine team in this video.

Backoffice Team

Backoffice is made of both Frontend and Backend Software Engineers. Together they build Stockly’s internal interface to ensure lean and productive Operations.

In all of these teams, we tackle highly complex mathematical and technical topics (integration with many systems, real time updates, pricing challenges, millions of items to manage…). To address these, we are looking for passionate and motivated people !

Integration Team

Integrations are at the core of our network reliability, they work on data exchange and integration between Stockly’s network and partners

• Coding new integrations (API plug-in, Scrapers, File parsing, etc) and improving existing ones

• Coding and improving integration-focused libraries

• Fixing integrations (SIT)

• Updating partner technical configuration

• Owning integrations as tech referee for other teams/partners

Thomas, in charge of the team, has not yet agreed to appear before the WTTJ cameras. We’ll have to wait another year, sorry…


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 focused of growth, we require that published code still work with ten times more volume.
