On behalf of LanguageWire, Ciklum is looking for a Senior .Net Engineer to join Kyiv team on a full-time basis.

LanguageWire is a global translation services provider.  We have built our own platform with a strong focus on automation and machine learning.

We have multiple teams developing parts of the combined solution: a business process management system, connectors for CMS and PIM systems, a web-based CAT tool, machine translation and NLP services.

Our team works on the core tools used for the translation process delivered as a set of micro services and we also own the public REST API. The team is located in the center of Kiev, at the Gulliver BC. The team consists of 3 developers, a QA engineer and a product director.

We do iterative development being close to our customers and releasing new features approximately every 3 weeks. We prefer direct communication over bureaucracy.

At LanguageWire we mostly use the Microsoft technology stack (we are three times Gold Microsoft partners), hosts most things on our own servers. A dedicated team of IT administrators and DevOps Engineers are responsible for the infrastructure. We are currently transitioning from a private cloud to a hybrid cloud strategy, leveraging containerization and infrastructure by code approach.


We are looking for an experienced developer who will work together with the existing team across all our services:

  • We write code in C#. We use async/await a lot, so you need to understand how the compiler transforms this syntax sugar and why async’s are needed
  • You should know your way around the base class libraries as well as your tools: Visual Studio & the debugger. We prefer to use as few third-party libraries as possible
  • Our services are document-oriented. We do a lot of processing, writing various parsers, readers and writers. You should care about the performance, for example, you would not load a 500 MB file into memory
  • Our services also store records in databases on the SQL Server. We do not have hundreds of tables, though migrations can be challenging. We use Entity Framework, but then validate generated SQL queries and execution plans. You need to understand the relational mode; index scans vs seeks to produce efficient queries. For migrations it is useful to know about window functions and common table expressions
  • Most of our services are background workers without any UI. They communicate through synchronous remote calls and the message bus. You should be able to design asynchronous communications, extend existing protocols, so that other services would not break. You also should be able to write relevant tests
  • We own a few REST API’s that exposes parts of our core functionality towards our Platform team, connector team, professional services team, integration partners and customers. We use Swagger to provide OpenAPI specifications for the consumers
  • In our transitioning towards a hybrid cloud setup we will need to phase out our current messaging bus architecture and replace it with a more optimal communication mechanism between our micro services
  • One of our most important consumers of the core tools is a Vue.js based web application. Knowledge and interest about how modern web applications work would be a nice skill to enrich the team with as well
  • We have one service that use the InDesign Server API via COM. So, experience with unmanaged code interoperation is welcome
  • Besides the development as such, we are also responsible for deployments and for providing tools for operational support. Background services are Windows services, you should be able to diagnose, why the service is not starting and generally know the Windows operating system architecture and tools well
  • As a team we are responsible for ensuring that our own services perform well, and we always need to develop for stability, speed and easy diagnosis of issues. We are currently transitioning to an ELK based logging strategy where we combine the logs from all our microservices into one place. This will give an overview of how our micro services performs and allow us to dive into the details of how a specific job progress through the various services when needed
