Back End Software Engineer II, Payments Platform

The Opportunity: 

We're looking for an experienced Backend Software Engineer, ideally with a background in FinTech, to help build and maintain the platform that powers Flywire's industry-leading payment engine — processing hundreds of millions of dollars every day.

You'll join a team designing new functionality and improving existing capabilities to enhance speed, cost efficiency, and scalability. We value collaborative problem-solving, pragmatic design, and a shared sense of ownership over what we ship. If you care deeply about code quality and want your work to have real-world financial impact, this role is for you.

Responsibilities:

• Write clean, testable, secure, maintainable, and extensible backend code across payment processing systems
• Investigate and resolve complex bugs and production issues with precision and care
• Work on non-trivial engineering problems that require deep evaluation of data, system behavior, and tradeoffs
• Understand and improve application scalability and performance proactively
• Contribute to technical design discussions and propose pragmatic solutions in line with team standards
• Collaborate with Product Managers, QA, SRE, and business stakeholders to deliver high-quality outcomes
• Support and participate in the hiring process by helping identify and engage strong engineering talent
• Drive AI readiness and adoption — leverage Claude via AWS Bedrock for AI-assisted development, intelligent code review, automated documentation, and smart observability across payment workflows
• Use AWS Bedrock's enterprise controls (IAM, CloudWatch, VPC, audit logs) to ensure AI usage remains secure, compliant, and fully observable within production environments

Here's what we are looking for: 

Required

• 4+ years of professional software engineering experience, with a strong backend focus
• Solid experience designing and building distributed, high-throughput systems
• Good understanding of TDD, BDD, and CI/CD best practices
• Strong command of OOP principles, clean code, and system design patterns
• Hands-on experience with relational databases (MySQL, PostgreSQL) and messaging/caching systems (Redis, AMQP)
• Strong grasp of OOP principles, clean code, and common design patterns
• Collaborative working style across QA, Product, SRE, and business teams
• AI readiness: Hands-on experience or strong familiarity with AWS Bedrock and invoking foundation models (particularly Anthropic Claude) via the Bedrock Runtime API or Converse API; ability to evaluate and responsibly apply AI tooling in production engineering contexts

Nice to Have

• Experience in FinTech, payments, compliance, fraud & risk, treasury, or FX domains
• Familiarity with AWS cloud-native design patterns, IAM, and VPC security configurations
• Exposure to integrating Claude into developer workflows (e.g., Claude Code, Bedrock-backed tooling) for engineering productivity
• Experience working in a Tech Lead capacity or supporting team mentorship
• Familiarity with Bedrock's enterprise features: CloudWatch metrics, OIDC/SSO integration, cross-region inference profiles

What We Offer:

• Competitive compensation
• Employee Stock Purchase Plan (ESPP)
• Flying Start - Our immersive Global Induction Program (Meet our Execs & Global Teams)
• Work with brilliant people that will keep you on your toes, learn more about their journeys by checking out #InsideFlywire on social media
