Context Plane Python Engineer

Are you a senior Python engineer who wants to work at the intersection of data platforms and applied AI? This is your opportunity to join a small, high-impact team building something new from the ground up — where your decisions shape the architecture, not just the backlog. At JPMorgan

Chase, we invest in engineers who are curious, pragmatic, and ready to grow into emerging technology stacks.

As a Senior Lead Software Engineer at JPMorgan

Chase within the Corporate Technology Data and Analytics Services team, you will be a founding contributor to the Context Plane — a greenfield platform that connects the firm's data mesh and knowledge sources to AI agents and large language model tools. You will own components end-to-end, from ingestion pipelines to governed retrieval services, and your engineering instincts will directly influence how the platform evolves.

This is a hands-on senior role with real architectural scope, active cross-functional collaboration, and strong support for internal mobility and upskilling.

Job responsibilities

Design, build, and maintain backend services and data pipelines in Python that load firm knowledge into a knowledge graph and vector store

Build and evolve the serving layer — including graph and vector retrieval, GraphRAG, response assembly, and a Model Context Protocol endpoint consumed by downstream agents

Extract and promote reusable components into a shared core library, reducing duplication across the platform's repositories

Integrate with data sources and services across the firm, including enterprise AI and large language model gateways

Own quality across your components: automated testing, code reviews, observability, and resilient, secure service design

Partner with Corporate Technology AI, product, and data science colleagues to translate concrete use cases into working, measurable capabilities

Contribute to design discussions and agile ceremonies, and actively mentor teammates to raise the engineering bar across the team 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

Required qualifications, capabilities, and skills

Formal training or certification on software engineering concepts and advanced applied experience

Demonstrated expertise building production-grade backend services and data pipelines in Python Strong command of API design principles (e.g., FastAPI), automated testing, CI/CD practices, and source control workflows

Experience designing and building data ingestion or integration pipelines at scale, with attention to data quality and resilience

Proficiency working with cloud infrastructure (AWS) and containerized services (Docker/ECS)
Ability to own technical components end-to-end — from design through deployment and observability

Strong collaboration skills with the ability to work across engineering, product, and data science disciplines

Hands-on experience using enterprise-authorized AI-assisted software development tools within the work environment (e.g., for coding, test creation, troubleshooting, or documentation) with demonstrated ability to critically evaluate, validate, and refine AI-generated outputs for correctness, performance, and security

Understanding of responsible AI use in engineering workflows, including data sensitivity considerations, secure handling of inputs/outputs, and adherence to resiliency and security expectations; ability to guide peers on safe and effective usage within team practices

Preferred qualifications, capabilities, and skills

Experience with graph databases and Cypher query language (e.g., Neo4j) or a strong interest in graph…
