XING is the social network for business professionals with
millions of members all over the world. Help us shape the future of

The international Payment & Billing team consists of business
analysts, developers and software test engineers. We closely work
with product teams to put together sales models, provide the
end-customer payment infrastructure and ensure a smooth billing
process.
We do this within a complex environment involving a number of
internal and external technical interfaces where human
collaboration is key to achieving success. Join our team and get
involved in lots of exciting new projects.

We work in diverse, small and cross-functional teams, and we
value the principles underpinning the agile manifesto.

We have offices in various parts of Europe (Hamburg, Munich,
Vienna, Barcelona, Porto and, more recently, Valencia). XING
employees come from more than 30 different countries and bring
their collective experiences and culture to work every day. Some of
us studied computer science, while others come from other fields or
don’t even have a degree-level qualification. The key common
ingredient is a willingness to learn and grow.

We try to make working in cross-location teams with as little
friction as possible. We believe in flexibility when it comes to
choosing when and where you deliver top-notch work.

In your team, you’ll not only interact with colleagues who have
various technology backgrounds (backend/frontend/iOS/Android
engineers), you’ll also work with product owners, designers, and
data scientists. We work with Scrum or Kanban in our teams
(depending on the team’s choice), conduct regular retrospectives,
and have agile coaches who mentor the team to ensure things are
done in line with best practices.

We support continuous learning.

Every engineer at XING has an annual conference allowance. We
also offer regular internal training sessions, meetups and brownbag
lunches throughout the year, as well as the opportunity to speak at
conferences – we’ll support you where we can. Other than training
sessions, you’ll have ample opportunity to grow and learn at work.
We work in cross-functional teams, giving you the opportunity to
learn and contribute to areas in which you might not yet be an
expert. We’ll always support you in growing your career, be it
moving into a new technology stack, learning leadership skills or
gathering enough knowledge in a certain field so as to become an
expert.

These training sessions are complemented by fun hack weeks held
three times a year where engineers are free to choose whatever they
want to work on and learn new technologies. Sometimes they build
wacky stuff like arcade machines or karaoke systems. Sometimes they
explore many up and coming technologies: using Elm when building
frontend applications, implementing parsers using Haskell,
exploring Istio for microservices infrastructure, building Ethereum
smart contracts using Solidity, and much more…
