Architect Platform

We're hiring a Senior Architect who owns architectural problems end-to-end and shapes how the engineering org builds, from system design and API contracts through implementation, reliability, and the patterns that make the next integration cheaper. You already use AI as part of how you think, design, build, and ship.

You'll design the systems that move money in production, set the API and integration patterns the engineering org adopts, and stay hands-on where it matters most. The work spans the connector framework and canonical data model across the accounting platforms our customers run, the Pay API hub, and the accounting orchestration layer behind them. You set architecture direction across the engineering org, lead cross-cutting decisions, and mentor mid-level architects and team leads., * Own the integration architecture for the ERP channel: the connector framework and canonical data model across Sage, Business Central, Dynamics 365 F&O, Xero, and NetSuite, plus the Pay API hub and the accounting orchestration layer behind them.

• Stay hands-on: lead prototyping of patterns that engineers adopt, write code in the hardest parts of new architecture, and lead architecture reviews across squads.
• Set architecture standards across the engineering org: API design, observability, security, and integration patterns that reduce the cost of the next integration.
• Lead cross-cutting architecture decisions, mentor mid-level architects and team leads, and grow the architecture practice across the engineering org.
• Lead how the engineering org adopts AI in architecture work: use agentic coding tools (Copilot, Cursor, Claude Code, or equivalent) daily across the SDLC, and shape AI use across design, code, testing, and documentation.

Do you have experience in Xero?, Must-have

• 7 to 10+ years building production software systems end-to-end, with at least 3 years in architecture-leaning work such as system design, platform engineering, or technical leadership.
• Track record designing and setting system architecture across multiple teams or the engineering org, including leading architecture reviews and mentoring architects and team leads.
• Strong backend proficiency in C# / .NET, our core enterprise stack, with hands-on coding still part of daily work; comfortable building on it long-term, with experience in other modern backend languages (Java, Kotlin, Go, or equivalent) transferring well.
• Solid CS fundamentals: object-oriented design, domain-driven design, data structures, and pragmatic system design.
• Deep understanding of service-oriented or microservices architecture, REST API design, and event-driven patterns.
• Strong SQL and relational database fundamentals, with familiarity with NoSQL where it fits.
• Production experience with AWS, including CI/CD pipelines (GitHub Actions or equivalent).
• Payments, FX, or regulated-industry experience.
• Daily use of agentic coding tools (Copilot, Cursor, Claude Code, or equivalent) across the SDLC, with a clear point of view on how AI fits into architecture work.
• Strong written and verbal communication, including the ability to explain architectural tradeoffs to engineering, product, and business audiences.

Nice-to-have

• Experience integrating with ERP or accounting platforms (Sage, Business Central, Dynamics 365 F&O, Xero, NetSuite).
• Experience building connector frameworks, unified or canonical APIs, SDKs, or integration orchestration.
• Familiarity with TOGAF, SAFe, or other architectural frameworks.
• Experience hiring, interviewing, or onboarding engineers and architects.
• Experience leading large-scale platform migrations or architecture transitions.

We want Xe to be a great place to work and to ensure that our communities are represented across our workforce. A vital part of this is ensuring we are a truly inclusive organization that encourages diversity in all respects.

Xe is a cross-border payments platform. We help SMEs and consumers in the US, UK, Canada, Australia, and New Zealand collect, convert, hold, and send money across markets. Each year, over 300 million people use Xe for currency information and over 350,000 use us to send money overseas. Today, we're rebuilding the platform layer behind cross-border payments for corporate and consumer clients. We're small enough that your code ships fast and your decisions matter, and Euronet Worldwide (Nasdaq: EEFT) backs us so the problems stay real-scale.
