Fullstack Software Engineer (.Net and React)

Tired of just writing boilerplate? Ready to orchestrate, refine, and ship high-impact product features with modern agentic workflows?

If you are a builder who pairs solid engineering fundamentals with cutting - edge AI dev tools to multiply your impact, you’ll fit right in. You won’t just prompt and hope - you know how to critically review, debug, and architect resilient code that actually scales.

Here’s a breakdown of what you’ll do (not all of it, just the important stuff):

• Drive product features end-to-end: Implement sleek, responsive UI improvements and connect them seamlessly with underlying APIs and backend services.
• Supercharge your workflow: Leverage agentic coding assistants and AI workflows to accelerate delivery, prototype fast, and automate repetitive engineering tasks.
• Be the human in the loop: Critically challenge, review, and refactor AI-generated code to maintain high architectural standards, security, and test coverage.
• Collaborate in cross-functional squads: Partner closely with product designers, managers, and peer engineers in an agile cadence to turn ideas into production-ready software.
• Level up code quality: Participate in code reviews, optimize client-side performance, and champion maintainable, clean-code practices across the codebase.

These are the essentials you’ll need to get an interview:

• Solid frontend foundations: Proven professional experience building modern, responsive web applications using modern JavaScript/TypeScript and component-based frameworks (like React, Angular, or Vue).
• Full-stack awareness: Comfortable navigating backend services, RESTful APIs, and basic data models to ship complete features independently.
• Hands-on agentic development: Demonstrated experience actively utilizing AI dev tools (e.g., Cursor, Claude Code, GitHub Copilot, Windsurf) in your daily development lifecycle.
• Strong code scrutiny & debugging: Exceptional ability to audit, debug, and refactor generated code for edge cases, performance bottlenecks, and architectural coherence.
• Pragmatic problem solver: A curious, product-first mindset with strong communication skills and an eagerness to learn and collaborate with a Budapest-based team.

It would be great if you had these too, but we’ll support you if you don’t:

• Experience with automated testing suites (unit, integration, and E2E like Jest, Playwright, or Cypress).
• Familiarity with containerized development environments (Docker) and CI/CD deployment pipelines.
• Hands-on experience building custom agentic workflows, prompt chaining, or LLM-driven tooling.
• Exposure to cloud-native platforms (AWS, Azure) or distributed systems.
