About the Project

Development and maintenance of a one-way integration service from 1C 8.3 (accounting system) to EspoCRM. The service is built on .NET 10 and performs unidirectional data synchronization — reading data from 1C via OData API and pushing it to EspoCRM via REST API, using RabbitMQ as the message broker.

Responsibilities

• Maintain and develop the existing integration service
• Develop new entity mappers and handlers from 1C to EspoCRM
• Configure and monitor RabbitMQ message queues
• Work with OData API to retrieve data from 1C
• Debug and fix data synchronization issues
• Participate in code reviews and code documentation

Required Skills

Must Have

• C# / .NET 10 — core language, async/await, generics, records
• RabbitMQ — message queues, consuming events from 1C
• MediatR — CQRS pattern, commands, queries, pipeline behaviors
• EspoCRM REST API — creating and updating entities via HTTP, token-based auth
• System.Text.Json — data serialization/deserialization

Nice to Have

• Swagger / OpenAPI — API endpoint documentation
• Cronos — scheduled task execution via cron expressions
• Docker — service containerization for deployment
• Git — version control

Big Plus

• Experience working with 1C 8.3 at a data structure level
• Familiarity with EspoCRM as a product
• Experience with .NET assembly decompilation tools (dotPeek, ILSpy)
• Understanding of Mapper, Repository, and CQRS design patterns

Requirements

We are looking for a Front-End Developer to work on customization and extension of our EspoCRM-based system.

This is not a typical React/Vue/Angular project. You will work within an existing platform with its own frontend architecture (views, models, templates, metadata), so the ability to understand and extend existing code is critical.

Must-have

• Strong knowledge of JavaScript (ES6+)
• Solid experience with HTML5, CSS3, responsive layout
• Experience working with large existing codebases, including the ability to read, understand, and safely extend custom code
• Understanding of MVC-style or component-based frontend architecture
• Experience with dynamic UI rendering (templates, state-driven UI)
• Experience integrating frontend with REST API / AJAX / JSON
• Good debugging skills (browser dev tools, network, DOM inspection)
• Experience with Git

Nice to have

• Experience with EspoCRM
• Familiarity with Handlebars or similar templating engines
• Experience with jQuery
• Understanding of Backbone-like or custom frontend architectures
• Experience with AMD modules
• Knowledge of LESS
• Familiarity with build tools (Babel, Rollup, Grunt)
• Understanding of metadata-driven UI and dynamic form logic

Candidate profile

We are looking for a developer who is comfortable:

• working inside a custom framework instead of modern SPA frameworks
• carefully extending existing functionality without breaking it
• maintaining code quality in a large and evolving system
• balancing between speed and clean architecture

This role is best suited for someone who enjoys engineering problems, not just building UI from scratch.
