Sr. Staff Software Engineer | Data Acquisition

WEX is a company focused on scaling its Data-as-a-Service (DaaS) platform, and they are seeking a Senior Staff Software Engineer to lead the development of their data acquisition systems. In this role, you will design and implement a flexible ingestion framework that supports various data processing pipelines while ensuring data quality and governance.

Responsibilities:

• Lead the design and development of scalable, high-throughput data acquisition systems that integrate internal and external data sources across domains
• Architect core platform components—such as data routing, transformation orchestration, lineage tracking, and schema evolution—using sound software engineering principles
• Implement a modular ingestion framework capable of supporting streaming and batch pipelines with varying latencies and SLAs
• Provide technical leadership, mentor engineers, and establish best practices in code quality, performance optimization, testing, and platform observability
• Collaborate with domain teams to understand data integration needs and accelerate onboarding through reusable patterns and automation
• Partner closely with the Control Plane and DataOps teams to integrate orchestration, lineage, access control, and validation into the core ingestion process

Requirements:

• 10+ years of experience in software or platform engineering with a focus on distributed systems, high-volume data processing, or data platform architecture
• Bachelor's degree in Computer Science, Engineering, or a related field required
• Deep understanding of data acquisition patterns at scale—including change data capture (CDC), event-driven ingestion, streaming frameworks, and asynchronous integration models
• Strong architectural experience with large-scale systems—you've built or led platforms that handle tens of millions to billions of records per day
• Experience building internal data platforms or ingestion frameworks that abstract complexity and accelerate domain adoption
• Strong programming expertise in a systems language (e.g., Python, Java, Scala, or Go)
• Strong appreciation for platform reliability, security, testability, and documentation as part of scalable engineering
• Experience integrating with a variety of source systems (e.g., CRM, ERP, telemetry, external APIs), and solving for schema evolution, observability, and error recovery
• Excellent communication skills and a passion for building platforms that empower others
• Masters degree in Computer Science, Engineering, or a related field
