Mid Front-End Developer (React, .NET)

About Algoteque

Algoteque is a Software Development and IT Nearshore company with over 15 years of experience in providing augmented teams and delivering scalable IT solutions for businesses across multiple industries.

We are looking for an experienced Front-End Developer with some experience in C#/.NET to join one of our internal projects at ALGOTEQUE — a web application developed for the aviation industry. You will be working on a complex, real-world product where code quality, component architecture, and reactive programming are at the heart of daily work.

What you'll be working with:

Frontend (Core Stack)

• React with TypeScript — writing typed, maintainable, production-grade code
• RxJS — state management and reactive data flows
• Axios — data fetching, interceptors, error handling
• Sass/SCSS — scalable styling architecture
• Component-driven development — reusable, composable, well-structured UI

Backend / BFF (Nice to Have)

• REST API principles — resource design, HTTP status codes, serialization, DTOs
• Authentication & authorization — JWT, OAuth 2.0, cookies, token refresh
• Security awareness — CORS, XSS, CSRF, Content Security Policy
• C# / .NET or other OOP language — understanding of OOP principles and architectural patterns (Dependency Injection, SOLID, MVC/MVVM) is a strong plus

What we're looking for:

• Strong hands-on experience with React in production environments
• Practical knowledge of TypeScript — you're comfortable with typed components, generics, and working toward type-safe architecture
• Experience with RxJS for state management — observables, subjects, operators
• Solid understanding of component architecture — you think in reusable, maintainable building blocks
• Familiarity with REST API integration — you know how to handle auth flows, errors, and async edge cases
• Awareness of web security fundamentals (CORS, XSS, CSRF)
• Good command of English — the team works in an international environment
• C# / .NET or another OOP language — big plus, especially for BFF-related work

What we offer:

• Work on a real product in the aviation industry — a stable, complex domain
• Collaboration with an experienced international team
• Fully remote
• Long-term engagement

Logistics:

• Contract type: B2B
• Start: ASAP / April 2026
• Location: Remote / Poland
