Opis stanowiska
Speeron is the leading integration partner for the hospitality industry. We help hotels deliver a fully digital, seamless guest journey - from arrival to checkout - through smart automation, integrated guest flows, and new revenue opportunities. All experiences are powered by the Speeron NEXT platform.
We are a Swedish-based company, operating in an international environment and building our products on the foundation of Scandinavian culture - characterised by trust, openness, collaboration, and work-life harmony.
We're looking for an experienced .NET Developer with Android experience and an AI-first engineering mindset to help shape the future of digital hospitality.
As AI transforms software engineering, we expect every developer to actively leverage modern AI tools - not only to write code faster, but to design better solutions, automate repetitive work, improve quality, and continuously increase team productivity.
WHAT YOU WILL DO
You'll help build a modern hotel digital experience used by guests worldwide - covering check-in/out flows, guest portals, self-service kiosks, digital keys, and next-generation TV solutions delivered across web, mobile, and dedicated hardware.
You'll work hands-on across the stack:
• Build .NET (C#) backend services, APIs and integrations
• Develop solutions running on browsers, Android devices and kiosks
• Build secure integrations with hotel systems and third-party services
• Participate in architecture discussions, sprint planning, demos and retrospectives
AI-First Engineering
You'll also be expected to:
• Use modern AI coding assistants (Claude Code, GitHub Copilot, ChatGPT, Cursor, etc.) as part of your daily development workflow
• Build and maintain your own AI-assisted development workflows
• Automate repetitive engineering tasks using AI agents
• Critically review, validate and improve AI-generated code
• Use AI to accelerate debugging, testing, documentation and refactoring
• Experiment with new AI tools and share best practices with the team
• Help us continuously improve how AI is used across engineering
We believe the best developers of today combine strong engineering fundamentals with effective use of AI.
PROJECTS
Speeron NEXT Interactive TV
An Android in-room TV platform running on set-top boxes. You’ll work on .NET backend and integrations for interactive TV, PMS-connected services, guest apps, mobile-to-TV control, and digital signage-all on one hardware platform.
Mobile Key Lock
A Kotlin-based Android app enabling guests to unlock rooms via BLE and NFC. You’ll build .NET backend services for secure key provisioning, Guest Portal integration, and digital key lifecycle management-powering a fully contactless experience.
REQUIRED COMPETENCE:
• 5+ years of professional software development experience
• Strong C#
• Experience building REST APIs and WebSocket-based systems
• Some experience with Android development and Jetpack components
• Understanding of Clean Code, SOLID and software craftsmanship
• Excellent communication skills in English (C1)
• GitHub Copilot, Claude Code, Cursor or similar AI-native development tools
AI Engineering
• Daily use of modern AI coding assistants
• Ability to effectively collaborate with AI agents while maintaining high engineering quality
• Strong prompt engineering and AI-assisted problem-solving skills
• Ability to evaluate AI-generated code critically rather than accepting it blindly
• Curiosity and willingness to continuously learn new AI tools and workflows
NICE-TO-HAVE COMPETENCE:
• Kotlin
• HTML5, CSS3, Bootstrap
• Angular, React or TypeScript
• Experience building AI-powered developer workflows or internal automation
• Experience integrating LLM APIs (OpenAI, Anthropic, Azure OpenAI, Google Gemini)
• Experience with MCP (Model Context Protocol) or AI agents
• Experience with Retrieval-Augmented Generation (RAG), vector databases or AI orchestration frameworks
• Experience publishing Android applications through Google Play
• BLE and NFC
• Raspberry Pi
BENEFITS:
• Full-time employment agreement or B2B contract
• Flexible work hours
• Work in international environment
• Conferences & Trainings
• Books reimbursement
• Sport package
• Private health care
• Recommendation bonus
• Scandinavian work style
We operate a flexible, remote-first work model with approximately 80-90% remote work. We ask you to pop into the office once a month, and every two months we gather the whole team for technical sync-ups (great for brainstorming and catching up face-to-face!). The role also necessitates ad-hoc availability for on-site attendance, primarily for the purpose of laboratory equipment configuration and maintenance. This approach balances autonomy with the collaborative touchpoints essential for high-performing technical teams.
If you want to build next-generation hotel guest technology, we’d love to hear from you.
