Senior Lead Software Engineer (Tax Solution), FinTech (Bangkok based, Relocation provided)

Get to Know our Team

Agoda’s FinTech teams build and operate the platforms that power our global financial ecosystem. From payments and reconciliation to tax, compliance, and financial reporting, these systems sit at the core of how we scale our business reliably and responsibly. 

As Agoda continues to grow across markets, products, and partner ecosystems, tax technology plays a critical role in enabling compliant, scalable, and efficient financial operations. Our teams work across product, engineering, finance, and architecture to design robust solutions that balance control, flexibility, and innovation. 

In this role, you will help shape the future of Agoda’s tax technology landscape, partnering with stakeholders across Finance and Technology to build resilient, enterprise-grade solutions that support a fast-moving global business. 

The Opportunity

We are looking for a Platform Architect to define and drive the technical direction of Agoda’s Tax technology ecosystem within FinTech. In this role, you will own the architecture vision and roadmap for scalable, secure, and compliant tax platforms that support Agoda’s global financial operations, high transaction volumes, and evolving regulatory needs. 

You will work closely with Finance domain experts, product managers, engineering teams, and fellow architects to translate complex tax rules and business requirements into robust technical solutions across Agoda’s internal systems, data flows, tax engines, and selected third-party platforms. 

As a senior technical leader, you will operate from strategy through implementation detail: guiding architectural decisions, challenging trade-offs, coaching engineering teams, and ensuring our tax platforms are resilient, adaptable, observable, and built for Agoda’s scale. You will help balance compliance and governance with engineering velocity, cost efficiency, and long-term platform quality. 

This position is based in Bangkok, Thailand. (Relocation support is provided)

In this Role, you'll get to:

• Shape the technical direction, architecture strategy, and long-term roadmap for Agoda’s Tax technology ecosystem, aligning Finance, regulatory, product, and engineering goals. 
• Own the architecture of mission-critical platforms and capabilities, ensuring they are scalable, secure, resilient, observable, and adaptable to Agoda’s global scale, with the key starting focus being the Tax platform.
• Design end-to-end solutions across internal systems, tax engines, APIs, data flows, and selected third-party platforms where they create clear business and technical value.
• Work hands-on with engineering teams on key technical decisions, system design, implementation trade-offs, proof-of-concepts, and critical architecture components.
• Lead architectural reviews and provide expert guidance on system design, integration patterns, reliability, maintainability, performance, and operational readiness.
• Translate complex tax rules, compliance requirements, and financial workflows into clear technical models that engineering teams can build, evolve, and operate effectively.
• Analyze Agoda’s current Tax technology landscape, identify systemic risks, duplication, inefficiencies, and modernization opportunities, and define practical transition paths toward the future state.
• Establish and evolve architecture principles, engineering standards, documentation, and governance practices that improve quality without slowing delivery.
• Drive improvements in quality, velocity, cost efficiency, scalability, and developer productivity across Tax-related systems and adjacent FinTech platforms.
• Mentor and influence senior engineers, Staff engineers, and technical leads, raising engineering fundamentals across design, code quality, testing, observability, and production ownership.
• Communicate complex technical trade-offs clearly to technical and non-technical stakeholders, including senior leaders across Finance, Product, Engineering, and Technology.
• Effectively utilize AI to achieve all the above, including contributions in building the solutions you helped design. 

What you'll Need to Succeed:

• 10+ years of experience in software engineering, architecture, or technology leadership roles, with a strong track record of designing and evolving complex production systems. 
• 3+ years of hands-on experience delivering tax-related technology projects across direct or indirect tax domains, or closely related finance technology domains, including building or evolving tax platforms.
• Strong understanding of Tax technology domains such as VAT, GST, corporate tax, withholding tax, compliance workflows, tax calculation, reporting, reconciliation, and auditability.
• Proven ability to shape technical strategy and architecture roadmaps across multiple teams, systems, or business domains.
• Strong hands-on engineering background, with deep understanding of system design, APIs, data flows, integration patterns, reliability, observability, scalability, and operational trade-offs for mission-critical systems, including high-volume transactional platforms at enterprise scale.
• Ability to translate complex business, finance, and regulatory requirements into clear technical models, architecture decisions, and executable engineering plans.
• Strong communication and stakeholder management skills, with the ability to explain complex technical trade-offs to senior engineering, product, finance, and business leaders.
• Proven ability to mentor and influence senior engineers, Staff engineers, technical leads, and cross-functional teams without relying on direct reporting authority.
• Strong ownership mindset, with a track record of identifying systemic risks, reducing duplication, improving engineering quality, and driving pragmatic modernization. 

It's Great if you have:

• Experience designing or modernizing global tax platforms that support multiple jurisdictions, products, currencies, and regulatory models.
• Deep experience with tax engines or tax automation platforms such as Avalara, Vertex, OneSource, or equivalent custom-built solutions.
• Experience with ERP systems, financial ledgers, invoicing, billing, reconciliation, or other finance platform integration points.
• Familiarity with event-driven architecture, streaming, or middleware integration technologies
• Experience with cloud-native architecture patterns, distributed systems, Kubernetes/EKS, serverless platforms, or large-scale service-oriented architectures.
• Understanding of data privacy, auditability, financial controls, and compliance frameworks such as GDPR, CCPA, SOX, or equivalent regulatory controls.
• Experience leading large-scale platform modernization, proof-of-concept work, or architecture transformation across multiple engineering teams.
• Exposure to large-scale global commerce, travel, payments, marketplace, or financial technology environments.
