We have an opportunity to impact your career and provide an adventure where you can push the limits of what's possible.

As a Lead Software Engineer - Data Engineering at JPMorgan Chase within Global Banking Technology, you will lead the design and delivery of reliable, scalable data platforms and pipelines that power business-critical use cases, including analytics, search/retrieval, and AI-assisted workflows. You will be accountable for building high-quality curated datasets with clear contracts, lineage expectations, and measurable SLAs/SLOs, while ensuring strong controls across security, privacy, resiliency, and auditability. You will remain hands-on and will set the technical bar for engineering rigor across Java and Python implementations, including batch/stream processing, microservices, and shared libraries. You will also partner with product, UX, and platform teams to enable AI/ML and agentic patterns where they materially improve business outcomes, without compromising governance or operational discipline.

Job Responsibilities

Design, build, and operate batch and streaming data pipelines that are reliable, observable, and cost-efficient, with clear runbooks and production support ownership.
Lead data modeling and curation for domain datasets, including schema evolution, data contracts, lineage expectations, and consumer-facing SLAs/SLOs.
Implement robust ETL/ELT workflows with strong validation controls, including reconciliation, completeness checks, anomaly detection, and automated alerting.
Engineer high-throughput data processing solutions using a combination of Java and Python, selecting the right tool for performance, maintainability, and platform standards.
Build and operate orchestration capabilities (for example, Airflow or equivalent), including scheduling, backfills, retries, dependency management, and operational SLAs with end-to-end ownership across architecture, engineering standards, CI/CD, and operational stability in a regulated enterprise context.
Deliver transformation pipelines using modern transformation frameworks (for example, dbt or equivalent), with strong testing, repeatability, and release discipline.
Develop and maintain supporting services and APIs (REST and/or gRPC) that expose curated data products and enable downstream consumers, using clean architecture and well-defined contracts.
Build and maintain search and indexing pipelines (for example, Elasticsearch) that support discovery, retrieval, analytics, and RAG-style experiences, and establish engineering and data quality standards across code review, automated testing, performance tuning, observability (logs/metrics/traces), resiliency patterns, and incident response.
Partner with security, risk, and controls teams to ensure data solutions meet governance expectations, including access controls, secrets handling, least privilege, and auditability.
Enable secondary AI/ML capabilities by delivering the data foundations required for evaluation, guardrails, tool/function integration, and traceable AI-assisted workflows, including MCP-style integration patterns where applicable.
Drives team adoption of enterprise-authorized AI-assisted engineering practices within the work environment to improve code quality, delivery speed, and operational outcomes (e.g., AI-assisted code review/refactoring, test strategy acceleration, incident/root-cause analysis support), while establishing consistent validation standards (secure coding, peer review, automated testing) and promoting reuse of effective patterns across the team.
Applies knowledge of tools within the Software Development Life Cycle toolchain, including enterprise-authorized AI-assisted development and automation capabilities, to improve the value realized by automation.
