Language Agnostic Backend Developer

About 35up

We want every shop on the internet to keep up with the big marketplaces.

Online marketplaces generate around 35 percent of their revenues through cross-selling by leveraging their large inventory and data processing recommenders.

Smaller online shops don't have this advantage. We don’t think that's fair - that's why we founded 35up. That's what the 35up platform is here to change.

Position

Your mission

As a backend developer you will be working on our key business challenges. We are a tech platform, so everything we do and everything we want to achieve involves good quality code.

Today, some Python using TDD. Tomorrow, clean code in Go and Elixir. Next week, maybe pair programming in Node.js? Feeling like writing a custom Nginx module in plain C? We have that too!

Sounds too cool to be true? Well, that's exactly how we roll here in the Tech Team at 35up!

This is a great opportunity to join a passionate team and make substantial impact on our business growth. You will experience supportive team members and the freedom to use your technical expertise and initiative to achieve shared goals. This position requires authentic curiosity and will to learn every day. We focus on quality and maintainability of what we do, in order to maximize the company goals in the long term, while executing urgent tasks with surgical precision when needed. We expect strong organizational skills, critical thinking and enthusiasm for achieving company and self-oriented goals.

Your responsibilities

• Code according to industry and team standards, adhering to good practices
• Write maintainable, readable code with extensive test coverage, ideally applying TDD
• Work with source control, dev/stage/prod release cycle and continuous integration
• Get actively involved in the code and functional reviews of fellow developer’s work
• Be able to spot logic and functional issues and effectively communicate feedback
• Actively engage with team members to discuss backlog items, design issues, and best coding practices
• Create technical documentation
• Optimize application for maximum performance, scalability and maintainability
• Working and developing RESTful APIs
• Be in direct contact with infrastructure topics and understand the systems architecture
• Work especially well with green field projects and sometimes with some legacy systems (luckily we already managed to kill most of these)

Your qualification

...is that you are open minded and eager to learn new technologies. You receive and give honest feedback and criticism, never taking it to the personal level, but as a fundamental part of achieving excellency.
