At Agoda, we bridge the world through travel. Our story began in 2005, when two lifelong friends and entrepreneurs, driven by their passion for travel, launched Agoda to make it easier for everyone to explore the world.

Today, we are part of Booking Holdings [NASDAQ: BKNG], with a diverse team of over 7,000 people from 90 countries, working together in offices around the globe. Every day, we connect people to destinations and experiences, with our great deals across our millions of hotels and holiday properties, flights, and experiences worldwide.

No two days are the same at Agoda. Data and technology are at the heart of our culture, fueling our curiosity and innovation. If you’re ready to begin your best journey and help build travel for the world, join us.

Get to Know our Team

Agoda’s Fintech Engineering team builds the core financial systems that power our business across brands – from B2B payments and settlements to billing, reconciliation, and financial reporting. We design and operate scalable, fault-tolerant services that must be correct, auditable, and resilient to change. Our work is a blend of deep domain understanding (finance, payments, B2B flows) and solid engineering practices: high-quality APIs, clear domain boundaries, and pragmatic architecture that can evolve with business. We collaborate closely with Finance, Product, and other tech teams to shape solutions end to end, and we value engineers who are as comfortable in a design discussion with stakeholders as they are in a code review with peers.

The Opportunity

We are looking for an Senior Lead Backend Engineer to drive architecture and domain-driven design in our Fintech domain. You will help define how we consolidate and evolve our B2B and financial systems, guiding multiple teams on technical direction, domain modeling, and system design. This role is ideal for someone who enjoys owning complex business domains, making high-impact architectural decisions, and working across teams—without formal people management responsibilities.

In this Role, you'll get to:

• Architect and evolve highly scalable, mission-critical backend systems in the Fintech domain (e.g., B2B payments, settlements, reconciliation, financial flows).
• Shape domain boundaries and system interactions using domain-driven design, collaborating with product and finance stakeholders to align technical solutions with business needs.
• Own key technical initiatives end-to-end: from clarifying requirements and writing RFCs/design docs to guiding implementation and rollout across multiple teams.
• Provide architectural guidance and technical leadership to several squads (backend, data, and related functions), ensuring consistent patterns, quality, and long-term maintainability.
• Dive into code where needed to validate designs, de-risk complex changes, and set engineering standards by example.
• Identify and drive optimizations across services (reliability, performance, cost, operability), focusing on pragmatic trade-offs rather than perfectionism.
• Partner with non-technical stakeholders (Finance, Product, senior leaders) to explain complex systems, trade-offs, and roadmap choices in clear, accessible terms.
• Contribute to and improve our engineering practices around observability, incident prevention/response, and continuous improvement in the Fintech space.
  
  

• 10+ years of experience in software engineering, with a strong background in backend systems and distributed architecture.
• Proven hands-on ownership of production services end to end: design, development, deployment, monitoring, and iterative evolution.
• Strong focus on architecture and domain modeling; you prefer solving complex domain and system design problems over low-level framework or micro-optimization work.
• Solid programming skills in at least one language such as Kotlin, Java or Scala with the ability to write and review production-quality code.
• Ability to perform deep research, write clear RFCs/design documents, and make informed architectural decisions on complex projects.
• High ownership and pragmatism: able to work independently, drive initiatives without waiting for detailed instructions, and make realistic trade-offs under constraints.
• Excellent communication skills, with the ability to explain complex technical and domain concepts to stakeholders at all levels, including non-technical partners in Finance and Product.
• Experience or strong motivation to work in fintech or financial systems (e.g., payments, billing, reconciliation, B2B financial flows), and willingness to go deep into the finance domain.
• Broad understanding of challenges and trade-offs across the stack (Frontend/Mobile, Data & Analytics, Infrastructure/DevOps) and how backend decisions impact them.
• Bachelor’s degree in computer science, Engineering, or a related field, or equivalent practical experience.
  
  

• Experience working in fintech-heavy environments (online banks, payment providers, trading platforms, or fintech teams within large product companies).
• Master’s or Ph.D. in a technical field.
• Experience with Kubernetes or similar platforms for running and scaling services in production.
• Strong knowledge of CI/CD practices, observability, and operational excellence in high-availability systems.
• Experience in other languages (e.g., Go, Rust, C/C++) or with event-driven and data technologies (e.g., Kafka) used in distributed financial systems.
