Jobs at Djinni

About the project

We are building a new industrial web platform designed to run both as an Azure-hosted SaaS solution and as an air-gapped on-premises installation from a shared codebase.

The platform uses modern .NET technologies, with Avalonia UI powering the user interface across browser-based WebAssembly and desktop applications.

You will help build the core UI framework, creating a reusable, modular, and high-performance interface for industrial dashboards and data-intensive applications.

The stack is .NET 10, ASP.NET Core, PostgreSQL/TimescaleDB, Keycloak, Docker and Kubernetes, with all UI in Avalonia.

We are looking for a Middle/Senior Frontend Developer with strong C#/.NET and Avalonia UI experience to build the user interface of a new industrial web platform running in the browser through WebAssembly and sharing code with desktop applications.

This is a UI-focused engineering role, not a traditional JavaScript frontend position. We are looking for someone experienced in building complex interfaces, reusable components, and UI architecture using Avalonia, or strong WPF/XAML expertise combined with hands-on Avalonia experience.

Requirements

• 5+ years of commercial experience with C# and .NET, including modern .NET versions.
• Production experience with Avalonia UI, or strong WPF/XAML experience combined with hands-on Avalonia development.
• Solid understanding of MVVM, dependency injection, and asynchronous programming.
• Experience building custom controls, styles, themes, and data-intensive interfaces such as grids, charts, and dashboards.
• Ability to write maintainable, testable code and collaborate through Git-based code review workflows.
• Availability to work remotely from within the EU and overlap with the US East Coast working hours from 08:00 to 13:00 ET.

Nice to have

• Experience migrating desktop applications from WPF or WinForms to Avalonia.
• Hands-on experience with Avalonia UI running in the browser through WebAssembly and understanding of its limitations.
• Familiarity with LiveCharts2, ScottPlot, OxyPlot, or commercial UI control libraries.
• Experience with plug-in systems or modular UI architectures.
• Unit testing of view models and automated testing practices.
• Knowledge of OIDC authentication, Keycloak, notifications, and file uploads.
• Experience optimizing WebAssembly applications through trimming, AOT compilation, or lazy loading.
• Familiarity with accessibility standards (WCAG) and localization.
• Experience building industrial, IIoT, manufacturing, or other data-intensive dashboard applications.
• Basic knowledge of ASP.NET Core and REST/OpenAPI.

Responsibilities
• Build the Avalonia UI shell: navigation, layouts, user preferences, and responsive and touch-friendly design.
• Create a reusable component library and themes (light, dark, high-contrast), with customer branding kept separate from themes.
• Implement UI extension points so plug-ins can add pages, dashboards and settings, with visibility driven by roles and licenses.
• Test and help select charting and control libraries for Avalonia WASM.
• Set up the localization architecture and port existing WPF screens to Avalonia.
• Optimize WASM load time and performance across the four target browsers.
• Write unit tests, take part in code reviews, and document UI decisions.

We expect a broad range of design skills, exceptional taste, and fluency with the latest AI design workflows. 

What you'll own 

• Design end to end across our vendor-facing and internal surfaces: research, flows, UI, and the details that make it usable at volume. 
• Work directly with product and engineering from the start of a problem, not just at handoff, shaping what gets built and not only how it looks. 
• Use AI-assisted design and prototyping tools as part of your default workflow, moving from idea to tested design fast, and help bring those workflows into our existing legacy designs. 
• Establish research and customer insight practice, so evidence is embedded from problem framing through delivery. 
• Drive competitor and market analysis, including the best current design patterns and industry examples, and use it to shape design direction and inform strategic priorities across teams. 
• Ground decisions in analytics and real usage data rather than preference alone. 
• Build and maintain a design system that holds up as the product and the team grow. 
• Give engineering enough clarity to build confidently, without needing pixel-perfect specs for everything. 

Requirements 

• 5+ years designing digital products for mobile and web. 
• A portfolio that demonstrates both design sensibility and real product depth. 
• Demonstrated research ability: you can plan it, run it, and turn it into direction. 
• Fluency with AI tools, with the ability to work directly in code rather than relying solely on prompts. 
• Strong Figma fundamentals: components, auto layout, variables, and systems that hold up under other people's hands. 
• Excellent communication, with a track record of working effectively with US-based stakeholders. 

Nice to have 

• Experience in retail, fueling, or loyalty domain products. 
• Experience improving user flows in complex domains with a large user base and high event volume. 
• Motion and brand design skills you can apply to product and marketing surfaces.
