About the Position

Introduction

JPMorgan Chase & Co. is seeking a highly skilled and experienced Lead Security Engineer to join the CTC Emerging Technologies Security group. In this pivotal role, you will be instrumental in designing, building, and operating an enterprise-grade Digital Asset Custody and Wallet Orchestration Platform. This is a unique opportunity to shape the future of institutional blockchain infrastructure within a leading global financial institution, focusing on secure, scalable, and compliant wallet services across multiple blockchain networks.

Responsibilities

Design, architect, and develop a production-grade digital asset custody & wallet orchestration platform, integrating with existing wallet infrastructure platforms via APIs and SDKs for provisioning, key management, and transaction orchestration.
Implement secure key management workflows utilizing Multi-Party Computation (MPC) and distributed key generation to ensure no single point of failure.
Build and configure programmable transaction policy engines, including multi-approval workflows, spending thresholds, velocity limits, and role-based access controls.
Develop multi-chain wallet capabilities supporting networks such as Ethereum, Bitcoin, Solana, and Polygon through unified API abstractions.
Manage the full blockchain transaction lifecycle, encompassing construction, fee estimation, payload signing, broadcast, confirmation tracking, and idempotent retry logic.
Design event-driven and webhook-based architectures to process real-time blockchain notifications and smart contract events.
Build secure RESTful APIs and microservices exposing wallet functionality to internal consumers, applying OAuth 2.0, JWT-based authentication, and API gateway patterns.
Develop and maintain integrations with compliance and risk systems, including transaction monitoring and comprehensive audit trail generation.
Implement robust observability across the wallet service stack using tools like Datadog, Dynatrace, and Splunk for distributed tracing, structured logging, alerting, and dashboarding.
Architect the wallet service for high availability, disaster recovery, and horizontal scalability using container orchestration on AWS (EKS/ECS), infrastructure-as-code (Terraform), and cloud-native resilience patterns.
Collaborate with product managers, security teams, and business stakeholders to translate regulatory and business requirements into technical designs and delivery milestones.
Contribute to a team culture that values diversity, opportunity, inclusion, and respect.

Requirements

Bachelor's degree in Computer Science, Software Engineering, or a related field.
7+ years of software development experience, with at least 2 years specifically in blockchain technologies or digital asset platforms.
Strong proficiency in Java/J2EE and/or Python, with hands-on experience building production microservices using frameworks such as Spring Boot, Flask, or FastAPI.
Solid understanding of blockchain fundamentals, including transaction models, consensus mechanisms, smart contract interaction (EVM-based and non-EVM), gas and fee management, and block finality across major networks.
Working knowledge of cryptographic primitives and protocols relevant to digital asset custody, including Multi-Party Computation (MPC), threshold signatures (TSS), distributed key generation (DKG), elliptic curve cryptography (ECDSA, EdDSA), and HD wallet derivation paths (BIP-32/BIP-44).
Experience designing and implementing policy engines or rule-based authorization frameworks for financial transaction workflows, including multi-signature schemes, approval chains, and configurable spending controls.
Proficiency with AWS cloud infrastructure, including EC2, EKS, Lambda, S3, RDS, IAM, SQS, SNS, API Gateway, and KMS, with experience using Terraform or CloudFormation for infrastructure-as-code.
Strong experience with containerization and orchestration using Docker and Kubernetes, including deployment pipelines and auto-scaling configurations.
Experience designing and consuming RESTful APIs, with a deep understanding of OAuth 2.0, JWT, TLS/mTLS, certificate management, and API security best practices.
Familiarity with event-driven architectures, webhook processing, and asynchronous messaging patterns for handling real-time blockchain state changes and notifications.
Experience with relational (Oracle, PostgreSQL) and NoSQL (DynamoDB, MongoDB, Redis) databases, including schema design, query optimization, and data consistency patterns for financial systems.
Proficiency with observability and monitoring tools such as Datadog, Dynatrace, Splunk, Grafana, or Prometheus for distributed tracing, log aggregation, and performance monitoring.
Solid understanding of agile development methodologies, CI/CD pipelines (Jenkins, GitHub Actions, Spinnaker), and DevOps practices in a large enterprise environment.

Nice to Have

Experience building or operating digital asset custody solutions in a regulated financial institution.
Experience using AI-assisted development tools (e.g., GitHub Copilot, Claude Code) to accelerate development and test generation.

Benefits

Opportunity to make a significant impact on the future of software security within a global financial leader.
Work at the cutting edge of distributed systems engineering, cryptographic security, and financial services technology.
Collaborate with high-performing teams in a supportive environment.
