Common Lisp Developer

Kyiv /
Engineering – Back-end /
Full time, permanent contract
Keepit is a cloud-to-cloud backup service provider. The purpose of our platform is to provide our customers with an immutable historical archive of their primary data in systems such as Microsoft 365, GSuite, Salesforce and Dynamics, to protect them from everything from ransomware to simple accidents.

At Keepit, we like to keep it simple. We like to think "less is more". We are one of the leading cloud data protection platforms in a very rapidly growing market and we can see that customers like what we do. We are looking for more colleagues to help us do even more.

The Keepit platform is a set of networked services working in concert; we have a strong emphasis on performance and reliability and this influences how we approach development and how we write our code.

The majority of our back-end components are written in clean modern C++ using mainly purpose-built components and the STL. Several components that deal with business processes and data mining are built using Common Lisp.

Everything runs on Linux. It runs on our servers that are run by our people. Our service operates from data center locations in Washington, Sydney, Copenhagen, Frankfurt and London - but we are a growing organisation and more regions will come.

At Keepit, the developer will contribute significantly to project specifications since deep technology understanding matters when we decide how to solve a problem.

At Keepit, we write code to last, since taking the time to do it right is faster than having to do things over.

At Keepit, developers will write test cases for their code, since if we can't prove to ourselves that code works there is little chance to impress QA.

Our approach to the development itself is ambitious and bold. We have developed components and systems that most organisations do not, which is securing us a solid lead in this rapidly expanding market of cloud to cloud backup. Backing up billions of objects over foreign APIs using imperfect networks on systems with finite memory and making it all happen in as little time as possible, is no small feat. We built the object store that holds these data too by the way. And we built every system in between and around as well. If you think solving hard problems is fun, we have strong indications that we will not run out of hard problems any time soon. Come join us for the fun!

Metadata extraction from large datasets, storage lifecycle management, resource accounting, complex test suites... While these problems can all be solved in any language given enough time and effort, they are more easily solved in more powerful languages. At Keepit we use Common lisp to solve these problems and we are looking to expand our team to grow our ability to solve more of these interesting problems in the future.
