Web3 Ethereum Jobs in United States, North America

A career with us is a journey, not a destination. This could be the next best step in your technical career. Join us.

You are a hands-on architect with a passion for building robust solutions and a keen eye for detail. You thrive on solving complex technical challenges, partnering closely with engineers and stakeholders, and applying emerging technology thoughtfully to deliver measurable outcomes in a highly controlled environment.

As a Lead Architect at JPMorganChase within the Kinexys team in the Commercial & Investment Bank, you will define and drive the technical target state for key products and capabilities. You will work side-by-side with engineering teams to design, build, and evolve secure and resilient solutions that meet business needs today while preparing for future growth. You will leverage enterprise-authorized artificial intelligence capabilities to accelerate architecture discovery and decision-making, applying strong human-in-the-loop validation and careful handling of sensitive data.

Job responsibilities

• Engage technical teams and business stakeholders to discuss and propose technical approaches to meet current and future needs
• Define the technical target state of your product and drive achievement of the strategy
• Leverage enterprise-authorized AI capabilities within the work environment to accelerate architecture discovery and decisioning, with human-in-the-loop validation and appropriate handling of sensitive data
• Evaluate recommendations and provide feedback on new technologies, including outcomes-oriented evaluation sessions with external vendors, startups, and internal teams to assess architectural designs and applicability within existing systems and information
• Execute creative software solutions, design, development, and technical troubleshooting with the ability to think beyond routine or conventional approaches to build solutions or break down technical problems
• Develop secure and high-quality production code, and review and debug code written by others
• Identify opportunities to eliminate or automate remediation of recurring issues to improve overall operational stability of software applications and systems
• Establish reuse-first AI-enabled engineering patterns and governance across software development life cycle and toolchain practices, ensuring traceability, auditability, resiliency, and security controls

Required qualifications, capabilities, and skills 

• Formal training or certification on architecture concepts and 5+ years applied experience
• Practical experience delivering system design, application development, testing, and operational stability
• Proficiency across software development life cycle execution, including automation and continuous delivery practices and agile methods such as continuous integration and continuous delivery (CI/CD), application resiliency, and security
• Demonstrated proficiency within a technical discipline (for example, cloud, artificial intelligence, machine learning, or mobile) and ability to evaluate current and emerging technologies to recommend future-state solutions
• Experience applying enterprise-authorized AI capabilities within the work environment in software engineering and architecture workflows, with strong validation habits and awareness of data sensitivity
• Ability to evaluate and integrate AI-enabled capabilities into cloud-native architectures while meeting resiliency, security, and auditability requirements
• Hands-on experience with public blockchain ledger platforms including Ethereum (Solidity, Ethereum Virtual Machine (EVM)) and alternative Layer 1/Layer 2 chains such as Solana, covering smart contract development, deployment pipelines, and token standards (ERC-20, ERC-721)
• Practical knowledge of the broader blockchain ecosystem tooling, including wallets, remote procedure call (RPC) providers, block explorers, indexers, and on-chain/off-chain integration patterns

Preferred qualifications, capabilities, and skills

• Experience with blockchain protocols, smart contract development, and decentralized application integration
• Experience with cloud migration, multi-cloud strategies, and cloud security best practices
• Familiarity with modern front-end technologies
• Exposure to emerging technologies in financial services
• Advanced proficiency in one or more programming languages
