As a Software Engineer at Joko, you will develop new features, new products, and improvements in order to bring value to the users of the different Joko products (mobile app, browser extensions, web services, etc.). You will have a full ownership of your projects and you will handle their development from A to Z, i.e. from the software design/architecture phase to the deployment in production.

The technical challenges that we are trying to solve at Joko are complex and diverse. For example, we are building our own web browser and are processing massive volumes of transactions every day. For this reason, we don’t want to build a team of specialists, with people who only work on specific tasks (e.g. mobile development, backend development, etc.), but a team of engineers with a wide range of skills that are able to solve complex engineering problems.

Your responsibilities:

• Software design: You will be responsible for challenging the vision of the Product team, and translating it into a viable architecture on all your projects.
• Software development: You will be responsible for the implementation of your software designs from A to Z, across our entire technical stack.
• Deployment & monitoring in production: You will be responsible for releasing your projects and monitoring their impact on the users together with the Product team.
• Research & development: You will also work on medium-term subjects, such as the real-time analysis of the content of web pages with machine learning algorithms, that will allow Joko to deeply transform the shopping experience of its users tomorrow
• Training & recruitment: You will actively participate in the training of newcomers and in the recruitment process.
• Tools & processes: You will help improve the way the Engineering team works by proposing new methods and by developing internal tools.

• Experience: You have at least one experience on a similar software engineering role, or a PhD in a relevant technical field.
• Problem solver: You have strong analytical skills, you are creative, and you love solving complex problems.
• Fast learner: You are comfortable in any technical environment and are able to quickly learn new programming languages, new frameworks, or new practices.

• Tech savvy: You are constantly looking at emerging technologies and you keep a close eye on the latest trends in the domain.
• Efficiency: You are fond of productivity tools and able to deliver on time on projects with many stakeholders.
• Attention to details: You know that the devil is in the details, and you have talent for spotting flaws when they exist.

• Communication: You have strong written and verbal communication skills, and you are able to explain something complex with simple words.
• Languages: You are fluent in English both written and spoken, as we are expanding internationally soon. Mastering French is not required.
