AI Modernization Senior Lead Software Engineer

Be an integral part of an agile team that's constantly pushing the envelope to enhance, build, and deliver top-notch technology products.

As an AI Modernization Senior Lead Software Engineer at JPMorganChase within the Consumer and Community Bank- Wealth Management Technology, you are an integral part of an agile team that works to enhance, build, and deliver trusted market-leading technology products in a secure, stable, and scalable way.

Drive significant business impact through your capabilities and contributions, and apply deep technical expertise and problem-solving methodologies to tackle a diverse array of challenges that span multiple technologies and applications.

In this role you will design, build, and ship the agentic systems that ingest decades of mainframe logic and produce verified, production-ready modern services.

You work directly alongside domain SMEs to turn legacy COBOL, JCL, DB2, and batch schedules into structured specifications - then drive those specs through agent-accelerated delivery into the target platform.

You are a builder first: comfortable architecting multi-agent orchestration one day and debugging a prompt chain against production edge cases the next.

You have deep proficiency extending and operating coding agents (Claude Code, Codex, Copilot), and you bring the engineering rigor to make AI outputs reliable at enterprise scale.

You thrive on hard problems, move fast, and care deeply about shipping software that works.

Job responsibilities



* Builds and operates the spec generation pipeline - Implement artifact ingestion (COBOL source, JCL, job schedules, DB2 schemas, SME-captured knowledge), chunking strategies, and RAG pipelines that produce structured calculation and workflow specifications validated by domain experts.


* Develops agentic workflows for code translation and migration - Design, implement, and iterate on multi-agent systems that translate legacy logic into target-state code (Kotlin/JVM).

Build orchestration layers, tool-use patterns, and guardrails that ensure output correctness for financial calculations.


* Builds evaluation and verification infrastructure - Create automated test harnesses that compare migrated calculation outputs against legacy results.

Implement parity testing frameworks, regression suites, and confidence scoring to gate production cutover decisions.


* Contributes to the standard calculation runtime - Help build and extend the target platform that migrated calculations deploy into.

Ensure the runtime supports deterministic, immutable, auditable execution.


* Partners with domain SMEs - Embed with mainframe subject-matter experts across Credit, Money Market & Mutual Funds, Statements & Tax, and IBOR to validate agent outputs, refine prompt strategies, and close knowledge gaps in specifications.


* Extends ETL and CDC pipelines for agent workflows - Build and integrate event sourcing, CDC (change data capture), and data pipelines that support end...
