Principal Engineer, Back End (Bangkok based, Relocation provided)

Department: Information Technology

Get to Know our Team

In Agoda’s Back End Engineering department, we build the scalable, fault-tolerant systems and APIs that host our core business logic. Our systems cover all major areas of our business: inventory and pricing, product information, customer data, communications, partner data, booking systems, payments, and more. These mission-critical systems change frequently with dozens of releases per day, so we must employ state-of-the-art CI/CD and testing techniques in order to make sure everything works without any downtime. We also ensure that our systems are self-healing, responding gracefully to extreme loads or unexpected input. In order to accomplish this, we use state-of-the-art languages like Scala and Go, data technologies like Kafka and Aerospike, and agile development practices. Most importantly though, we hire great people from all around the world and empower them to be successful. Whether it’s building new projects like Flights and Packages or reimagining our existing business, you’ll make a big impact as part of the Back End Engineering team.

• Collaborate with TPMs and stakeholders to define and drive the technical vision and roadmap for AI-driven querying, query engines, and data quality tools.
• Mentor engineers and raise standards across data quality & governance tools, query engines, and the broader data platform.

What you'll Need to Succeed:

• 10+ years of experience in software engineering, data engineering, or related fields
• Strong hands-on experience with:
  • SQL and large-scale data systems
    
  • Modern analytical databases / data warehouses (e.g., StarRocks, Snowflake, BigQuery, ClickHouse)
  • Backend development (e.g., Python, Java, Scala or similar)
• Experience building or working with:
  
  • AI/LLM-based applications (e.g., text-to-SQL, conversational interfaces, cursor, copilots)
  • Data platforms or analytical infrastructure at scale
    
• Strong understanding of data modeling, query execution, and performance optimization
• Proven ability to lead cross-team, high-impact technical initiatives
• Ability to navigate between deep hands-on work and strategic technical leadership
• Excellent communication skills with both technical and non-technical stakeholders
  

It's Great if you have:

• Experience with text-to-SQL systems or AI-driven data interfaces
• Experience implementing or scaling analytical engines such as StarRocks
