- Description
- About Xe
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.
About This Role
We're hiring a mid-level back-end engineer who likes owning real problems end-to-end, from API design and data modeling through to service implementation, production reliability, and launch.
You already use AI as part of how you think, build, test, and ship.
You'll write code that moves money in production, build and modernize the backend services the platform runs on, and ship new capability as Xe rebuilds its platform layer.
You'll work in a small team with direct access to product, compliance, and operations, own your services in production, and partner with architects and team leads on bigger design decisions.
What You'll Do
- Build backend services that move money and manage multi-currency balances across a range of domains, including onboarding, KYC and KYB, payment initiation, FX, settlement, and other supporting services.
- Partner with product, compliance, and operations from problem framing through launch.
- Build and operate the partner integrations and settlement infrastructure your services depend on.
- Own your services in production, including reliability, observability, on-call, and incident response.
- Use agentic coding tools (Copilot, Cursor, Claude Code, or equivalent) daily across the SDLC, and help take parts of the platform from legacy services into the modern stack alongside architects and team leads in your domain.
What We're Looking For
- Must-have
- 3 to 6 years building production backend services, end-to-end.
- Strong backend proficiency in C# / . NET preferred; other OOP languages welcome (Java, Kotlin, Go, or equivalent).
- SQL and relational database fundamentals.
- Writing and maintaining tests.
- Daily use of agentic coding tools (Copilot, Cursor, Claude Code, or equivalent) across the SDLC.
- Production experience with AWS, including hands-on deployment and native services such as SQS, Dynamo DB, S3, ECS, and Lambda.
- Strong system design fundamentals, including distributed systems and async or event-driven patterns.
- Strong written and verbal communication.
- Nice-to-have
- Experience in payments, FX, or cross-border money movement.
- Service-oriented or microservices architecture experience.
- Experience with ledgers, double-entry accounting, or other financial-data systems.
- Experience with CI/CD pipelines and modern deployment practices.
- Experience with caching solutions like Memcached or Redis.
- Experience using project management and documentation tools like Jira and Confluence.
- Knowledge of API testing tools such as Postman or Bruno.
- Writing automated tests alongside development with AI tools (Claude Code or equivalent).
Perks & Benefits
- Competitive Salary & Discretionary Bonus
- 23 days annual leave increasing with service (capped at 28 days)
- Paid day off for your Birthday
- 4% employer pension contribution
- Discounted Euronet ESPP
- Life Cover, Income Protection & Critical Illness cover
- Healthcare
- Plumm Mental Health and Wellbeing
- Volunteering day for a charity of your choice
