Job Description
Responsibilities:
Proactive Customer Experience:
- Build features that anticipate customer needs and remove friction before questions arise.
- Make critical information (e.g. flight details, trip changes, add-on excursions) clear, timely, and accessible across app, web, and communication channels.
- Design systems that reduce uncertainty and increase trust through smart automation and clear user experience.
Reactive & AI-Driven Automation:
- Help design and build AI-powered chatbots and voicebots to maximize self-service and reduce manual support.
- Automate inbound and outbound customer communication related to trip changes (flights, hotels, schedules).
- Apply AI pragmatically to classify, route, resolve, or fully automate customer interactions.
Product & Data-Oriented Engineering:
- Work closely with the whole team to refine problems before writing code.
- Use data to validate assumptions, measure impact, and continuously improve solutions.
- Actively participate in shaping product decisions, not just implementing tickets.
Requirements:
Strong problem-solving mindset — you enjoy ambiguous problems and figuring out the best path forward.
- Highly effective use of AI in daily work (coding, debugging, designing, analyzing, automating).
- Product-oriented thinking: you care about why you’re building something, not just how.
- Comfort working across multiple technologies and learning new ones as needed.
- Solid knowledge of RESTful API design, development, and integration best practices.
- Experience working with event-driven architectures (EDA) and message-based communication between services.
- Familiarity with Domain-Driven Design (DDD) and clean architecture principles.
- Working knowledge of CI/CD pipelines and version control best practices using Git (GitHub Actions or similar).
- Strong emphasis on testing (unit, integration) and commitment to code quality, scalability, and maintainability.
- Familiarity with observability practices — including logging, monitoring, and tracing — to ensure visibility and reliability across distributed services.
- Excellent collaboration and communication skills to work effectively within cross-functional teams.

- Backend: PHP and/or C# (or equivalent experience)
- Frontend: React, React Native
- APIs, integrations, and system design
- AI tools, LLMs, automation workflows
