Sr Software Engineer, Disputes at Visa

Join Pismo’s Disputes squad, responsible for building and evolving a highly reliable platform that manages the full chargeback lifecycle, from dispute creation through pre‑arbitration and resolution, supporting issuer efficiency, automation, and network compliance. You’ll work in a high‑availability, high‑compliance environment, developing APIs and services that connect issuers to major payment networks and keep issuer systems synchronized through real‑time events. The team also owns Protection Bulletin, a critical capability that ensures transaction continuity during issuer unavailability via stand‑in authorizations and automatic synchronization once the issuer is back online. What You’ll Do • Develop and maintain services using Golang (and Java/JVM technologies when needed), following clean code and strong software engineering practices. • Design and implement scalable, reliable, and secure microservices on AWS, evaluating trade‑offs across performance, resilience, maintainability, and operational complexity. • Collaborate closely with engineering and product partners to translate business requirements into effective technical solutions. • Build event‑driven solutions leveraging AWS services such as SQS, SNS, DynamoDB, S3, and EventBridge. • Use Terraform to provision, evolve, and maintain cloud infrastructure following Infrastructure‑as‑Code best practices. • Write and maintain automated tests (unit and integration) to ensure code quality and system robustness. • Work with SQL and large SQL databases that provide the persistence layer for our applications, understanding their limitations and operational characteristics at scale. • Monitor service health and performance using observability practices and tools (metrics, logs, alerts), proactively identifying and resolving issues in distributed systems. • Participate in code reviews and provide constructive feedback focused on code quality, security, scalability, and cross‑domain impact. • Contribute to architectural and technical discussions that support continuous improvement and long‑term platform evolution.This is a remote position.
