Senior Software Architect - Platform
About The Position
Data Commerce Solutions (DCS) is a Fiserv business unit that turns the company's differentiated data into scalable data platforms and products across credit, marketing, verification, fraud, and data insights. The Senior Software Architect is the hands-on technical owner of reusable platform capabilities supporting multiple DCS product verticals, combining architecture with direct software engineering. The role is responsible for producing secure, scalable, supportable platform services, including capabilities to migrate data science proofs of concept into versionable, enterprise-scale production code. This is an on-site role Monday through Friday. In-person collaboration is considered essential to the role and is intended to support onboarding and productivity. Approximately 10% travel off-site or to other office locations is expected. Candidates must already possess valid and unrestricted U.S. work authorization; candidates requiring sponsorship now or in the future will not be considered.
Requirements
- 10+ years of progressive software and data engineering experience, including significant responsibility for architecture and hands-on delivery of distributed systems.
- Advanced coding proficiency in Java and strong working knowledge of Python and data science development patterns.
- Demonstrated experience converting notebooks, experimental pipelines, models, or analytical prototypes into versioned, tested, maintainable production software.
- Deep experience with Spark, microservices, REST or event-driven APIs, SQL and NoSQL systems, containerization, Kubernetes, and cloud architecture; Microsoft Azure is preferred.
- Experience designing CI/CD and MLOps or DataOps workflows, including artifact repositories, automated testing, model or feature versioning, observability, and controlled promotion across environments.
- Strong understanding of distributed systems, performance engineering, data formats such as Iceberg, Delta Lake, Avro, and Parquet, and Lakehouse, batch, and streaming architectures.
- Hands-on knowledge of Git, Maven or Gradle, automated testing, Agile, and DevOps practices.
- Ability to communicate complex architecture through concise documentation, diagrams, and code.
- Bachelor's degree in computer science, engineering, or a related field, or an equivalent combination of education and relevant experience.
- Must currently possess valid and unrestricted U.S. work authorization; sponsorship is not available now or in the future.
Nice To Haves
- Experience building internal developer platforms, model or feature platforms, code transformation frameworks, or self-service engineering capabilities.
- Experience with domain-driven design, test-driven development, infrastructure as code, SRE practices, and high-volume transaction processing.
- Experience in financial services, banking, payments, credit, marketing, verification, fraud, or data insights.
- Master's degree in computer science, engineering, data science, or a related discipline.
Responsibilities
- Own the architecture, design, coding, testing, and production implementation of shared data and software platform capabilities in a hands-on engineering role.
- Create an engineering framework and automation to convert data science proofs of concept—including notebooks, Python code, features, models, and validation logic—into modular, testable, version-controlled, deployable software.
- Implement CI/CD, validation, promotion, observability, rollback, and lineage for production workflows.
- Re-engineer proof-of-concept workloads for enterprise scale, including distributed processing, low-latency serving, batch throughput, fault tolerance, and cost optimization.
- Build reference implementations and production code using technologies such as Java, Python, Spark, Spring Boot, APIs, microservices, containers, Kubernetes, and cloud-native data services.
- Architect reusable, secure platform services for data ingestion, feature engineering, model execution, workflow orchestration, metadata, policy enforcement, and monitoring, with built-in security and privacy controls.
- Establish coding standards, reusable libraries, templates, test harnesses, and paved-road deployment patterns.
- Partner with data scientists, product, security, DevOps, and SRE teams to define production-readiness criteria.
- Lead architecture decisions through working code, prototypes, design documentation, and performance tests.
- Participate in production issue resolution and evaluate emerging technologies to improve reliability, scalability, and engineering velocity.
- Mentor early-career engineers while maintaining high engineering standards.
Benefits
- Annual incentive opportunity for incentive-eligible associates, which may be delivered as a mix of cash bonus and equity awards at the company's discretion.
