Full-time | Remote | ASAP

We are hiring an experienced .NET Engineer for a new technology product aimed at making warehouse operations smarter and more efficient, particularly when it comes to capacity and space management.

The project is currently at its initial development phase. Rather than joining a mature platform with established solutions, you’ll be helping turn the product concept into its first functional version and determine how its core backend should work.

This position involves a mix of backend engineering, data processing, distributed systems, and computational problem-solving.

What You’ll Work On

Your focus will be on creating the technical backbone of the platform, including:

• Engineering server-side functionality with C# and the .NET ecosystem
• Creating service interfaces and defining how data moves between system components
• Implementing messaging-based communication with Apache Kafka
• Handling asynchronous processes and event-based workflows
• Translating complex operational requirements into reliable backend logic
• Processing and managing substantial volumes of application data
• Developing solutions for calculation and optimization scenarios
• Defining technical approaches together with a small engineering team
• Taking features from an initial idea to a working implementation

• Applying AI development tools and agent-based workflows as part of the engineering process

   

Background We’re Looking For

You should have substantial professional experience developing backend applications with C# and .NET, along with a strong understanding of how production backend systems are structured.

For this position, we also need:

• Real-world experience using Apache Kafka
• Knowledge of messaging patterns, asynchronous communication, and event-based systems
• Strong understanding of software architecture and designing backend solutions
• Practical SQL experience
• Experience creating and integrating RESTful services
• Solid knowledge of data structures and algorithms
• Ability to break down technically complex problems and find practical solutions
• Confidence working with limited initial specifications and choosing appropriate technical approaches without constant guidance
• Experience That Would Be Useful

Additional relevant experience may include:

• Microsoft Azure or another major cloud provider
• Systems involving large datasets, calculations, or optimization
• Rapid prototyping and PoC / MVP development
• Greenfield engineering and early product development
• Software for logistics, warehousing, stock management, or supply chain operations

• Development workflows involving AI coding assistants

   

Technology Landscape

C# | .NET | ASP.NET Core | Kafka | SQL | REST

What Makes the Project Interesting

You’ll join while the product is still taking shape, giving you meaningful involvement in both implementation and technical direction.

The engineering challenges go beyond standard backend feature development and include distributed processing, algorithms, optimization, and data-intensive workflows.

You’ll work in a compact team where engineers have considerable autonomy, short decision-making paths, and direct influence on the resulting product.

We’re looking for someone who can join in the near term, ideally ASAP.

What’s In It for You?

• Career Growth – Opportunities to develop and advance.
• Performance Reviews – Regular feedback and support.
• Work Anniversaries – Special gifts to celebrate milestones.
• Flexible Work – Hybrid or remote (Lviv office available).
• Mentorship – Guidance from experienced professionals.
• Accounting Support – We handle the paperwork.
