As our global footprint grows, so does the number of bugs we need to solve and new features we need to ship, could be frontend, backend or both, hence the need of full stack. Your main responsibility will be to handle tickets, identify the bug and solve it, sometimes you will have to ship new features too. We are a small but fast growing and friendly team, since the founders were freelancers before, we hire lots of freelancers and have a well functioning freelance-first work culture, we are not annoying at all and you will love working with us : 100% guaranteed. Requirements - Basic English is enough, we care more about your technical skill - Chinese proficiency is a plus, but absolutely not required (the CTO is Chinese, although the company is French and Paris based) - Very very very autonomous - Strong experience in fullstack engineering (the old fashion way) - Strong experience in vibe coding - Upwork timer only - We will do a quick paid test before deciding to hire you, to see you shine with real work.
