At Flywire, we’re on a mission to deliver the world’s most important and complex payments. We use our Flywire Advantage - the combination of our next-gen payments platform, proprietary payment network and vertical specific software, to help our clients get paid, and help their customers pay with ease - no matter where they are in the world. What more do we need to truly be unstoppable? Perhaps, that is you! Who we are: Flywire is a global payments enablement and software company, founded more than a decade ago to solve high-stakes, high-value payments in higher education. We’ve since scaled into new regions and industry verticals and expanded our product offerings to deliver meaningful value to our clients around the world. Today we support more than 4,900+ clients across the global education, healthcare, travel & B2B industries, with diverse payment methods across 240 countries & territories and more than 140 currencies. With over 1,200 global FlyMates, representing more than 40 nationalities, and in 12 offices world-wide, we’re looking for FlyMates to join the next stage of our journey as we continue to grow.a Job Description The Opportunity : We, at Flywire, are looking for a highly experienced Senior Software Engineer II. As a Senior Software Engineer II, you will be a key contributor and technical leader for our billing and payments product that supports the money movement of hundreds of millions every day. This is a full-stack role that requires a blend of deep technical proficiency, architectural foresight, and the ability to navigate highly complex client requirements. You will be expected to work autonomously, often driving cross-team technical initiatives, while maintaining a strong, collaborative presence with other teams across the globe. The ideal candidate for this position is a person that thrives in taking on challenges of high scope and complexity. You will be joining a small team in Australia that will be in charge of designing new functionality, improving our current core capabilities, and elevating our engineering practices. We are looking for an engineer who balances a pragmatic, long-term design approach with a commitment to building highly secure, reliable, and scalable systems. Key Responsibilities Architecture & Development: Architect services and systems using well-accepted design patterns to allow for iterative development and future scaling. Working closely with US technical leadership, you will translate global architectural vision into local execution, confidently starting new projects from scratch in high-risk, high-volume areas while consistently applying SOLID principles. AI-Augmented Engineering: Design and implement team-level AI-augmented workflows that measurably improve velocity for the Australian engineering team. You will evaluate new AI tools (assessing ROI, security, and data privacy), mitigate risks at a systems level, and create reusable configurations that benefit teammates locally and abroad. Operations & Reliability: Drive, design, and deliver software that meets strict reliability, performance, and scalability requirements. You will define SLOs/SLIs, actively work with global security teams to refine organisational strategy, and act as a regional owner for postmortems to ensure long-term mitigations are executed. Complex Problem Solving: Act as the primary technical escalation point in the APAC time zone to identify and solve complex cross-system problems. You will lead local and cross-team groups during high-urgency production issues, correctly assessing scope and impact, and collaborating with global teams for seamless incident handoffs. Leadership & Mentorship: Serve as the Tech Lead on the ground in Australia. You will mentor the local team, structure technical proposals into the global company roadmap, defend team goals, and foster a culture where teammates openly share opinions—using contradictory viewpoints to drive constructive conversations. Project Management & Productivity: Successfully manage the Australian team's commitments, roadmap planning, and delivery in alignment with the global team. You will critically review epics to ensure they are appropriately sized, schedule technical debt relative to global cross-team changes, and routinely manage multiple major projects simultaneously. Strategic Communication: Act as the technical bridge between the Australia office and the global team. You will distill technical feedback from global teams into concrete local proposals, and communicate effectively across Flywire and with external clients, maintaining composure and clarity in high-pressure discussions. Technical Requirements Advanced Java Proficiency: Expert-level professional experience in Java development, with a deep understanding of how libraries and software evolve over time (often reading vendor libraries to identify undocumented behaviors). System Architecture: Deep understanding of relational databases (MySQL), infrastructure tooling, and cross-system data flows. Expertise in applying common patterns for service reliability (retries, failover, circuit breakers, etc.). Core Stack: Extensive experience with Spring Core, Spring MVC, and Hibernate, alongside the ability to evaluate and determine new technologies that align with current usage. Front-End Skills: Familiarity with HTML, CSS, JavaScript, and JSP (Java Server Pages). Modern Workflow & Automation: Ability to drive automation and performance indicators for services, leveraging advanced monitoring tooling and AI-assisted tools for enterprise-grade deployment. Qualifications Here's what we are looking for : Minimum of 8+ years of relevant experience Strategic & Visionary: You contribute directly to the organization's engineering strategy and documentation. You evaluate and create new product features in collaboration with the product team while continually simplifying product and technical design. Culture Builder: You foster a culture of clear, concise, audience-oriented communication. You work within your team to instill priority setting and urgency aligned with organizational goals. Adaptable: You have the aptitude to learn new systems or legacy codebases quickly and can manage your own time effectively to meet deadlines. Cross-Functional Collaborator: You proactively anticipate problems in cross-team projects before they require escalation and gladly help other teams unblock design doubts using your deep architectural knowledge. Global Collaborator: You enjoy working with diverse teams across different time zones and possess outstanding verbal and written communication skills. Professional experience in application development commensurate with the SS2 level (extensive track record as a lead or principal-level contributor in a complex production environment). Proven ability to independently identify, scope, and deliver cross-team technical solutions. Experience in FinTech, Payments, or Higher Education sectors is highly appreciated. Demonstrated history of successfully managing multi-team projects, architectural design, and high-pressure incident response.
