Software Architecture - Sr Advisor I

Fiserv•Remote, Florida, FL

About The Position

Finxact is an innovative, enterprise-class, 100 percent open API, cloud-native banking platform and transaction processing engine. It is designed to support banking, fintech, and embedded finance organizations with a highly scalable, resilient, and adaptable technology platform. We are seeking a Staff Software Engineer – Event Messaging to provide technical leadership in the design, development, and evolution of Finxact’s event-driven platform and messaging capabilities. This role combines hands-on software engineering with architecture and technical leadership across highly distributed, event-driven systems. You will help define and implement scalable messaging patterns and services using Golang, Apache Kafka, Kubernetes, REST, gRPC, and cloud-native technologies. You will work across engineering teams to improve the reliability, scalability, performance, and operability of our eventing platform while establishing architectural standards and engineering practices for asynchronous communication. Experience with change data capture technologies, including CDC and Debezium, is highly valuable for this role.

Requirements

7+ years of professional software development experience designing, developing, and supporting production software systems.
Significant experience with software architecture, technical design, and technical leadership for complex distributed systems.
5+ years of Golang development experience building production applications, services, or platform components.
Strong experience designing and implementing event-driven architectures.
Strong production experience with Apache Kafka, including producers, consumers, topics, partitions, consumer groups, offsets, retention, and delivery semantics.
Experience designing messaging systems for scalability, resiliency, throughput, availability, and failure recovery.
Strong understanding of distributed-system concepts including concurrency, consistency, idempotency, fault tolerance, backpressure, and asynchronous processing.
Experience designing and developing RESTful APIs and gRPC services.
Strong experience with Kubernetes and containerized application architectures, including deployment, scaling, configuration, resiliency, and troubleshooting.
Experience integrating applications with relational databases such as PostgreSQL or MySQL.
Experience operating applications and distributed services in AWS, Azure, GCP, or similar cloud environments.
Experience with automated testing, integration testing, performance testing, observability, and production troubleshooting.
Ability to translate business and product requirements into scalable technical solutions.
Strong written and verbal communication skills, including the ability to communicate architectural decisions and technical tradeoffs across engineering teams and technology leadership.
Bachelor’s degree in computer science, engineering, or a related field, or an equivalent combination of education, work, and/or military experience.
