Full job description

PROJECT OVERVIEW

Our client is a software company building an intelligent document processing and management platform. The platform is in an active architectural evolution - transitioning from a structured monolith toward a fully distributed microservices system.

IN THIS ROLE, YOU WILL

  • Design & develop scalable web APIs using C# 12 and ASP.NET Core, ensuring high performance, security, and maintainability across multi-threaded server environments;

  • Work with multiple data stores - MSSQL, MongoDB, and Solr (Elasticsearch-based);

  • Build and maintain microservices communicating exclusively via RabbitMQ, contributing to the ongoing migration from a monolithic architecture;

  • Integrate with AWS services;

  • Implement document recognition and parsing pipelines;

  • Apply software architecture best practices - SOLID principles, design patterns, and clean code standards;

  • Champion code quality through testing, debugging, and thorough code reviews;

  • Collaborate in an agile environment with distributed teams, contributing to architectural decisions and the evolution of the platform.

IF YOU ARE

  • Experienced with C# , ASP.NET Core, and .NET Core;

  • Proficient in MS SQL Server and writing optimized SQL queries;

  • Experienced with MongoDB and document-oriented data design;

  • Comfortable with Entity Framework;

  • Familiar with RabbitMQ for async, event-driven service communication;

  • Experienced with AWS - especially S3, Textract, Bedrock;

  • Knowledgeable in Docker containerization and cloud-native deployment practices;

  • Comfortable working in systems transitioning from monolith to microservices;

  • Strong in OOP design, algorithmic thinking, and distributed systems patterns;

  • A collaborative problem-solver with a positive, can-do attitude in agile teams.

NICE TO HAVE

  • Experience with Solr;

  • Familiarity with VectorDB or vector embedding workflows;

  • Experience with IronPDF or similar PDF processing libraries;

  • Knowledge of Azure APIs;

  • Background in document recognition or intelligent parsing systems.

AS AN OPINOV8R, YOU WILL HAVE

  • Digital-First Approach: Great talent knows no borders! You can work from wherever you are — we hire and collaborate with professionals worldwide.

  • Remote Work Model: Balance your professional and personal life with our flexible working conditions, empowering you to deliver your best from anywhere.

  • Exciting Projects: Dive into impactful projects across industries that challenge and spark creativity.

  • Boost Your Expertise: Grow your career with continuous learning, development opportunities, and hands-on experience.

  • Join the Best Team Ever: Collaborate with our diverse and cross-cultural team of passionate technologists and creative thinkers.

HOW’S THE HIRING PROCESS GOING

We strive to make our hiring process smooth and transparent to find the perfect match for both sides. Steps may differ depending on the role, but here’s what to expect:

  • Initial Interview: If your background fits the role, we’ll invite you for an interview with a Talent Acquisition Specialist.

  • Technical Interview: Depending on the position, you may complete a technical assessment or test task.

  • Client Interview.

  • Final Decision: After all steps, we’ll get back to you with the result and next steps.
