Senior backend software engineer

42Hexagons is looking for a Senior Backend Software Engineer to complete its software development team for its flagship product: Flexomatic.

The context

Our product is a niche Android app deployed on thousands of devices which helps independent delivery workers grab pieces of work called “Blocks” on Amazon Flex. Every single day day, our app grabs around 200 blocks for our customers on their behalf, sparing time and money for them.

Job content

Being part of the software development team, you will refer to our CTO and take part in the backend development. Here are the key points of your role:

• bringing brand new features to life;
• enhance the codebase and constantly ensuring it preserves a maintainable state;
• adding tests and enforcing them so there will be no regression on the app;
• enforcing technical watch to update and improve our tools.

Examples of major features we would like to implement

• Fair system between our users (Backend would decide which user is the most in need for work)
• Predictive modeling, improving efficiency and usability of our app, with Machine Learning
• Plug iOS’ Flexomatic version with the backend
• Duplication of Flexomatic on the other actors of the Gig Economy (Deliveroo, Instacart, Glovo, Spark Driver etc.), with total freedom to reinvent the stack

Required skills

• Significant experience on Web development. We are not asking for “years of experience”; if you have a few websites/apps to show us and tell us how your work fit into it, that would be great.
• Knowledge of an imperative programming language. We are using Python and Flask, but you are not required to know both of these tools. As a software engineer, you should be able to tackle issues by yourself. Whether you’ve coded in PHP, Ruby or any other language to build awesome backends, we’re confident that you will feel at ease with Python.
• English proficiency. The team is majoritarily made of French speakers, so whether you come from an English spoken country or elsewhere, we will have to communicate in proper English.
• You know how to use a Version Control System (VCS). We work with github on a daily basis, so we expect you to be able to handle git if you don’t already know it.
• Knowledge of Android development is a plus.

Technical environment

• Frontend : HTML/Bootstrap (for the landing page) – Android/Kotlin.
• Backend : Python 3.8/Flask.
• Database: PostgreSQL.
• Infrastructure: Heroku.
• Other: Git, Trello, Slack.

Location

Full-remote. We are all based in France so if you are close to UTC+1, that would be great but that should not help you from applying to this position.

Additional information

The expected workload is of 40 hr/week maximum with a negotiable hourly rate. We are looking for a mid-term collaboration starting from August 1st 2021.
