The role
We are looking for a Backend Developer with experience in machine learning to join our Research & Development team. You will help build machine learning research prototypes and be responsible for integrating them into new and existing products.

The goal of the team you will be joining is to deepen the understanding of how machine learning can scale the company. The team is working on 50M+ PDF documents (catalogues, magazines, etc.) to figure out new ways to utilize the documents, e.g. detecting and extracting articles, auto-generating social posts, etc. This work includes PDF decomposition, image analysis, document structure analysis, and text analysis and categorization.

We are the right company for you, if you

    • want to work on a product that matters to a lot of people – we handle hundreds of visits per second and host 50M+ documents,
    • consider yourself one of the best at what you do and you're looking for equally talented colleagues,
    • are self-driven and would never just want to take the next ticket,
    • are curious and never stopped learning and exploring new languages, technologies, and solutions,
    • seek a culture where all voices matter when it comes to shaping the future of the product,
    • want to work with colleagues who have a ‘here to help’ attitude, and absolutely want to help you succeed,
    • be part of an international team that continuously challenges the status quo.

What you bring with you

    • a Master’s degree in CS or equivalent,
    • experience with Python and machine learning frameworks such as Keras and PyTorch,
    • experience with functional languages  (preferably OCaml),
    • experience with machine learning models (validation, verification, and visualization),
    • strong competencies in data structures, algorithms and software design,
    • experience designing and building robust, high-volume production systems,
    • experience with scalable microservice architecture,
    • excellent communication skills in English.

Other things you should know are

    • we're currently working on Issuu’s Story Cloud both on web and mobile apps, machine learning for better understanding of our content, internal analytics and our famous reading experience to mention a few examples,
    • We currently use Kotlin, Python and Javascript,
    • our architecture is microservice-oriented using AMQP,
    • we deploy multiple times a day on AWS and use Docker Swarm and Kubernetes, MySQL, Redis, Node, etc.,
    • we strive to be agile (who doesn’t?), but we're not religious about Scrum, Kanban or any other methodology,
    • we have many cross-team guilds where we share knowledge, coordinate efforts, and help each other the best we can,
    • "20% time”: everyone gets one day a week to invest as they see fit (i.e. learn something new, experiment with new ideas in the product, join efforts with others, improve what you think matters, etc.).

The impact you will have on our customers

    • create new things they could not have done before,
    • share those creations with more people than they could have reached before,
    • reach new levels of success than they could have imagined before.

What you'll get

    • a competitive compensation package,
    • meaningful equity in a profitable growth-stage company,
    • health and dental insurance,
    • a flat structure – every opinion matters regardless of team or position.
