Staff Software Engineer – Data Acquisition

WEX is seeking a Staff Software Engineer to lead the technical direction and delivery of its data acquisition platform. The role involves building reusable ingestion services and pipelines, guiding architecture and engineering practices, and ensuring data quality, reliability, security, and recovery across batch, CDC, and streaming systems.

Responsibilities:

• Build and maintain high-performance data acquisition pipelines that integrate with a variety of systems across WEX and third-party vendors
• Lead the design and delivery of a modular ingestion platform with reusable connectors and configuration-driven onboarding. Establish metadata and configuration patterns that reduce source-specific development and support Data Acquisition as a Service
• Build schema validation, completeness checks, reconciliation, duplicate prevention, and audit logging into shared ingestion components
• Support safe retries, replay, backfills, and schema evolution so failures can be recovered without losing or incorrectly duplicating data
• Design batch, CDC, and streaming ingestion patterns that meet agreed freshness, throughput, and recovery requirements. Evaluate performance, source-system impact, and operating cost when selecting and extending ingestion technologies
• Ensure traceability, lineage, and security through integration with control plane and governance systems
• Lead design and code reviews, maintain technical specifications and architectural decisions, and mentor engineers in reusable platform design
• Establish automated testing and CI/CD practices for ingestion code, connector configuration, and infrastructure, with validation before production deployment
• Partner with the established production support process on complex escalations, root-cause analysis, and preventive engineering improvements

Requirements:

• B.Sc. in Computer Science, Engineering, or related technical field
• 8+ years of software engineering experience, including delivery of production distributed systems or data platforms and demonstrated technical leadership across team boundaries
• Strong programming skills in Python, Java, Scala, or another systems-focused language
• Experience with data integration and ingestion pipelines—you understand what it means to bring data in from source systems, transform it, and deliver it reliably downstream
• Solid grasp of engineering fundamentals, including version control, modular design, testing, and performance tuning
• Demonstrated experience designing and operating production integrations that handle schema evolution, failure recovery, observability, and secure access
• Ability to lead architecture decisions, explain engineering tradeoffs, resolve dependencies across teams, and guide implementation through production adoption
• Practical experience using AI-assisted engineering tools for design, coding, testing, or documentation, with validation of generated outputs for correctness, security, and maintainability
• A collaborative mindset—comfortable working across domains, products, and infrastructure layers
• A strong sense of ownership and accountability—you care deeply about building systems that last
• Experience building reusable connectors, metadata-driven ingestion services, or configuration-driven onboarding capabilities
