pubx
London

Company Description

pubX is a small, agile, VC-backed start-up working to deliver artificial intelligence technology which will revolutionise the digital publishing industry.

Our mission is to enable digital publishers to monetize more effectively by helping them to fight back against Advertising Technology that has been designed to commoditize and lower the price of their inventory by creating cutting edge technology of a similar calibre to that used by advertisers and media agencies.

We believe that publishers are a cornerstone of society and democracy and that if advertising trends continue as they are, publishers will be lost to the world, along with truth, objectivity, and knowledge, replaced by walled garden echo chambers which are a pernicious component of society and fuel and foster hate.

Job Description

We are looking for a javascript developer with some experience of frontend development to help us build publisher focused AdTech products.

Working in a small team with backend developers and ML engineers, you will work across the full product offering including big data wrangling in aws, apache spark ETL processes, a django based API, a React UI, and javascript page tags.

Your day-to-day will involve writing, testing, and debugging the code that powers our publisher facing products. You will have an opportunity to innovate and bring your own ideas to bear on customer problems and will have a meaningful input on the solutions that we bring to market.

You will be working in a broadly agile process, but will have the opportunity to shape the processes and structure as the company grows. Additionally you will have a large degree of freedom in selecting the appropriate tools and approaches you use to solve customer problems, but with the support of experienced developers when needed.

Qualifications

You should have 3+ years of experience working in a range of development roles, and be able to demonstrate a broad knowledge of development technologies as well as a deep understanding of python and javascript.

You should be focused, eager to learn and explore new things, and work well in a team. You should be comfortable with abstract reasoning and communicating complex ideas clearly.

You should have an interest in code quality and know how to use best practices to produce high quality software.

Ideally you will have had some exposure to adtech or marketing in general. Any direct experience with header bidding technologies or Google DFP/GAM would be a big plus.

Skills:

Strong problem solving skills.

Broad experience with web development technologies

Experience using git source control and front end build tools like webpack.

Essential skills

  • Python

  • Javascript ES6

  • HTML3 / CSS3

  • React

  • Working Experience with responsive web design.

  • Familiarity with

Additional Information

We're a small, ambitious company, as committed to helping digital publishers as we are to creating a culture that aligns with our values.

Our values are: trust, community, agility and curiosity.
