Senior Software Engineer (Java/Backend)

Blis is the leading privacy-first, location-powered programmatic advertising partner. We deliver accurate targeting at scale without reliance on personal data, helping the world’s largest brands and media agencies drive key business outcomes through personalised and high-performing digital advertising. 

Blis uses real-world and online data, as well as behaviour and lifestyle indicators, to profile and understand audiences better than anyone else. Using a global planning and measurement panel of 1.5 billion consented devices and taking an aggregated and anonymous approach to audience targeting, Blis reaches precise audiences at scale without reliance on personal data. 

Established in the UK in 2004, Blis now operates in more than 40 offices across five continents. Working with the world’s largest and most customer-driven companies across all verticals including Unilever, Samsung, McDonald's, HSBC, Mercedes Benz and Peugeot, as well as every major media agency, Blis reaches over a billion mobile devices a year.

We are looking for brilliant, creative, curious, and experienced Java backend software
engineers to join our applications team. This team delivers internal and customer-facing
applications to manage complex ad campaigns and to provide deep reporting, analytics, and
data visualisation capabilities sourced from big data and machine learning technologies.
They also help with a range of other offline and online projects, from our proprietary
algorithms and systems for location data processing to integrations with third-party
technologies to bring in additional data and decision capabilities. As a tech-first product
company, this team works on things that are visible and matter to customers and the
business!

Software engineers at Blis are more than just programmers - they’re people who are
builders, designers, and problem solvers at heart, people with a passion to make things
better. You will help innovate and design new features and products, work with the team to
build them, and support and grow them after they’re live. We discuss ‘why’ as much as
‘what’ and ‘how’ in our planning meetings because we want you to see and help shape our
future. We value soft boundaries between teams and you’ll get to work with other
engineers, data scientists, and product managers to see how it all comes together. As
engineers, you’ll help us follow good design principles, especially those inspired by Lean
Development, and you’ll enjoy learning, growing, and pushing yourself and the products in
new ways. And, of course, you’ll enjoy being part of a team that supports each other
through mentoring, brainstorming, and pairing up to solve ambitious challenges.
