Software Engineer III

Summary

Join FastSpring, a rapidly growing digital goods and gaming reseller, as a Software Engineer III, Payments & Risk. This fully remote role focuses on building and improving a risk engine to minimize fraud and optimize revenue. You will design and implement data-driven solutions, leveraging industry best practices and collaborating cross-functionally. The position requires expertise in backend programming (Java), payments and risk, and a strong understanding of data analysis. FastSpring offers a competitive salary, comprehensive benefits, and professional development opportunities.

Requirements

• 3-5 years of experience as a Lead Engineer, or key technical contributor in a fast-growing Fintech organization, preferably with international payments
• Expertise in back-end programming with Java
• Understanding Payments and Risk as a complete domain
• Passionate about Resilience and data Observability
• Independent Deductive Ability from data - you know the philosophy, principle and practices of data and apply it daily at work. E.g., Type I vs Type II errors, Correlation Coefficient, when to use heat map vs. stacked bar chart etc
• Ability to treat most external technology as “black box services with iron clad contract” but fully expect them to degrade or even be unavailable for extended periods of time. In the end, our customers don’t care about the depth of the tech stack but only if it works for them all the time. We aim for 99.99%+ uptime for our Payment Services - every month

Responsibilities

• View our Payments domain as a “cube” of Customers, Payment Methods and Geography and design an empirical system to best optimize for our sellers’ revenue in every cell, while not impacting any other
• Build a customer-facing (both buyer and seller) minimally intrusive solution that uses industry best practices (3DS, KYC, MFA, Threat Score, External Services, Internal Model based on recent and past behavior etc) set of services and solution to minimize fraud (chargeback, dispute, alert) that increase our customers’ revenue and have a positive impact on NPS (Net Promoter Score)
• Understand and discover the nuances between Payment Methods and customer purchase behavior in different geographies (in global and local currencies) and encode the enduring behavior in a set of actionable rules
• Security, Resilience and Scale are three pillars of our Engineering Excellence - built on the foundation of Observability. You will proudly own end-to-end actionable observability in Payments and Risk domain, and proactively add and/or tweak it as we execute our Product Strategy (“Ship One New Payment Method a month”)
• Cross-functional Influence - this role, especially, requires a degree of “healthy paranoia” to succeed. Your success will be fueled by that, but could only be achieved with a high degree of internal collaboration and influence to balance your “sense of urgency”
• You must deeply believe and live with the technical philosophy of “unreasonable effectiveness of data”. Data must trump opinion, or even past experience, in an overwhelming majority if not all of your decisions

Benefits

• 401(k), including company match
• Comprehensive benefits package, including Medical, Dental, Vision & supplementary coverages
• Flexible PTO and 13 Company Holidays
• Bi-weekly 'FastSpring Friday' half-days
• Work-from-home essentials reimbursement
• Professional development opportunities & education reimbursement
• Peer recognition programs & awards
