We’re looking for a Senior .NET Backend Engineer to join a small team and help build a new product from an early stage.
The product is focused on improving warehouse efficiency and space utilization. You’ll work on backend architecture, complex business logic, data processing, algorithms, optimization tasks, and event-driven backend services.
The first goal is to build and validate a working MVP / Proof of Concept, so we’re looking for someone who is comfortable working with ambiguity, making technical decisions, and building things from scratch.
Start: ASAP
What you’ll do
Build backend services using C# / .NET
Design and implement APIs and database workflows
Work with Kafka and event-driven architecture
Work with complex business logic and large amounts of data
Solve algorithmic and optimization-related tasks
Participate in architecture and technical decisions
Help build the product from scratch
Work independently and take ownership of technical solutions
Use AI coding tools and agentic engineering approaches to speed up development
What we’re looking for
Strong commercial experience with C# / .NET
Strong backend development skills
Hands-on experience with Apache Kafka
Good understanding of event-driven architecture and asynchronous processing
Strong understanding of backend architecture and system design
Hands-on experience with SQL
Experience building and working with REST APIs
Good understanding of algorithms and data structures
Strong analytical and problem-solving skills
Ability to work independently and make technical decisions
Nice to have
Experience with Azure or other cloud platforms
Experience with optimization, algorithms, or data-heavy systems
Experience building MVPs / Proofs of Concept
Experience launching products from scratch
Experience with logistics, warehouse, inventory, or supply chain systems
Experience with AI-assisted development / AI coding tools
Tech stack
C# · .NET · ASP.NET Core · Apache Kafka · SQL · REST APIs
Why this role
Technically challenging product with real-world optimization problems
Significant influence on architecture and technical decisions
Small team with high ownership
Opportunity to build a product from the very beginning
Minimal bureaucracy and direct impact on the product
Opportunity to actively use modern AI-assisted engineering approaches
If you enjoy solving complex backend problems, working with distributed systems, algorithms, and data, and building products from zero - we’d be happy to talk.
