Middle/Senior Developer

Kraków, Czech Republic Keepit Full time
Required skills: 
  • 3+ years of commercial experience with one (any) programming language
  • Knowledge of at least on with a different paradigm – preferably a combination of objective and functional
  • Good understanding of TCP, HTTP, RESTful APIs and XML
  • Used to working on and coding for Linux systems
  • General SQL understanding
  • Practical git knowledge
Bonus skills: 
  • Working knowledge of GNU Make
  • Working knowledge of C++ and Javascript
  • Knowledge of Common Lisp
Keepit is looking for developers eager to switch to Common Lisp from any back-end language. 

We are growing fast as a company and do our best to bring our SaaS cloud-based backup services to the global audience. 

Our platform is designed to provide customers with an immutable historical archive of their primary data in systems such as Microsoft 365, Google Workspace, Salesforce, Entra ID, Dynamics 365, and Zendesk. It aims to protect them against everything, from ransomware to simple accidents. 

Most of our back-end components are written in clean, modern C++ using mainly purpose-built components and STL. Several components that deal with business processes and data mining are built using Common Lisp. Everything runs on Linux. 

At Keepit we use Common Lisp for metadata extraction from large datasets, storage lifecycle management, resource accounting, and complex test suites. We want to expand our team to grow our ability to solve more of these interesting problems in the future. 

Why Common Lisp? 

Common Lisp is, as the only truly programmable programming language, the most powerful programming language in existence. It is also interesting because it supports interactive development, allowing one to inspect the intermediate results and data structures. It also supports recompiling a single function in an already running program (similar to hot reloading), making it fast to try out changes. Common Lisp is a mature and stable language. It is a multi-paradigm, supporting both functional and object-oriented programming. 
Once one is past the hurdles of learning Common Lisp and (one of) the preferred IDEs, such as Emacs with Sly, it provides a really great and unique developer experience. 

A fair and transparent recruitment process

During the recruitment process, you can expect the following stages:
CV screening, Recruitment interview, Technical assignment, Technical interview.

You will be assessed according to the criteria below:  

  1. Technical skills: We are looking for candidates proficient in Common Lisp programming with all the necessary skills.
  2. Team collaboration: You must be able to negotiate with the team regarding improvements to our product and structures.
  3. Language: English is a preferred language, and we expect you to be fluent in both written and spoken.
