Job Description

Join Apaleo and Shape the Future of Hospitality Tech!

Apaleo is the world's most open, API-first property management platform powering the next generation of hospitality operations. Its modular, AI-powered infrastructure enables hoteliers to customise their tech stack, automate routine work, and deliver seamless, personalised guest experiences, powered by best-in-class apps and autonomous AI agents that adapt to every stay.

We are looking for a Senior Backend Engineer (f/m/d) to build the foundation of Apaleo's market-facing API layer, bringing agentic booking into hospitality and enabling the next generation of guest-facing AI experiences.

This is a highly autonomous role where you will design and ship the Storefront API, a production-grade, scalable interface that allows external systems (like ChatGPT and booking platforms) to interact directly with Apaleo.

You'll operate at the intersection of backend engineering and AI, starting with clean API architecture and evolving into systems that power intelligent, agent-driven interactions.

What You'll Be Up To

Build the Storefront API from Scratch

• Design and implement a production-grade, multi-tenant API / MCP
• Enable seamless integration with external platforms and AI agents
• Ensure scalability, reliability, and high performance from day one

Own the Full API Lifecycle

• Define API schemas and contracts (OpenAPI)
• Implement versioning strategies and backward compatibility
• Design authentication, authorization, and security patterns
• Build rate limiting and usage controls
• Ensure strong documentation and developer experience
• Set up monitoring and observability

Work Across Distributed Systems

• Integrate with existing .NET microservices
• Connect to event-driven systems (Kafka or similar)
• Navigate and improve a complex distributed architecture

Operate in the Cloud

• Deploy and manage services in AWS
• Work with Docker and containerized environments
• Contribute to infrastructure as code practices

Collaborate on AI-Driven Use Cases

• Partner with AI engineers to enable agent-based workflows
• Build APIs that integrate with LLM-powered systems
• Help evolve the platform toward AI-native product capabilities

Shape Engineering Standards

• Define best practices for:
  • API design
  • System architecture
  • Code quality and maintainability
• Contribute to how the ecosystem team scales and operates

What You'll Bring to the Team

Core Requirements

• Proven experience building and operating production-grade APIs at scale
• Strong expertise in REST API design and architecture
• Solid experience with C# / .NET 8+
• Hands-on experience with AWS, Docker, and infrastructure as code
• Strong understanding of microservices and distributed systems
• Ability to work independently and make architectural decisions
• Interest in AI systems and integrations

Mindset & Traits

• Self-starter — you take ownership and drive work without waiting for direction
• Comfortable with ambiguity — you can build in evolving, low-structure environments
• Pragmatic decision-maker — you balance speed with long-term scalability
• Builder mindset — you enjoy creating systems from scratch
• Curious about AI — you're motivated by where backend systems meet intelligent agents

Nice to Have

• Experience with:
  • Event-driven systems (Kafka or similar)
  • Multi-tenant SaaS architectures
  • Developer-facing or public APIs
• Exposure to:
  • LLM integrations or agent-based systems
  • Python
  • Any major frontend framework
• Background in hospitality tech (not required)

Why This Role Matters

This role is about more than building APIs, it's about defining how external systems interact with Apaleo in an AI-first world.

You'll:

• Lay the foundation for market-facing, AI-integrated products
• Enable guest-facing experiences powered by intelligent agents
• Help transform Apaleo into a platform ready for autonomous systems

Expert Career Tips for Senior Backend Engineer (.NET) (f/m/d) Roles

To succeed in a competitive market as a Senior Backend Engineer (.NET) (f/m/d), you need more than just technical skills. Here are some expert strategies to elevate your profile:

• Build a Strong Portfolio: For technical roles, a clean GitHub or a personal project site is essential. For non-technical roles, a case study portfolio demonstrating problem-solving and impact is equally valuable. Show, don't just tell, what you have achieved in your previous positions.
• Master the Narrative: When interviewing, use the STAR method (Situation, Task, Action, Result) to structure your answers. Quantify your results wherever possible—mentioning "increased efficiency by 20%" is much more impactful than saying "improved efficiency."
• Continuous Learning: The industry moves fast. Whether it's staying updated with the latest AI tools or mastering a new management methodology, continuous professional development is key. Consider obtaining industry-recognized certifications that align with Senior Backend Engineer (.NET) (f/m/d) requirements.
• Networking: Connect with other professionals in similar roles. Join online communities, attend webinars, and engage in meaningful discussions on professional social networks. Often, the best opportunities come through referrals and community engagement.
• Soft Skills Matter: Communication, empathy, and leadership are often the deciding factors between two equally qualified technical candidates. Cultivate these skills as they are universally valued across all industries and seniority levels.

Additionally, research the specific company's culture and values. Tailoring your application to show how you align with their mission can significantly increase your chances of moving forward in the process.

Comprehensive Application Strategy & Hiring Process

Applying for a new role is a marathon, not a sprint. Follow this strategic approach to maximize your success rate:

1. Initial Research & Tailoring

Don't send the same resume to every employer. Spend at least 30 minutes researching the company. Look for recent news, their product roadmap, and their team structure. Modify your summary and core competencies to reflect the specific keywords found in the job description.

2. The Perfect Cover Letter

If the application allows for a cover letter, use it to tell a story that your resume cannot. Explain why you are passionate about this specific company and how your unique background makes you the perfect fit for the challenges they are currently facing.

3. Navigating the Multi-Stage Interview

Most modern hiring processes involve 3-5 stages. This typically includes a recruiter screen, a technical or skill-based assessment, a peer interview, and a final leadership round. Prepare for each stage differently: focus on enthusiasm and fit for the recruiter, technical depth for the assessment, and strategic vision for the leadership round.

4. Post-Interview Follow-Up

Always send a personalized thank-you note within 24 hours of each interview. Reference a specific topic discussed during the call to demonstrate your active listening and genuine interest in the role.

By following these steps, you demonstrate a high level of professionalism and attention to detail that sets you apart from the average applicant.

Typical Interview Process

1. Resume screening
2. HR call
3. Skill interview
4. Final manager interview
5. Offer

Tip: Research the company's products and culture.
