Fidelity is seeking a Director of Blockchain Architecture to design and architect applications within our Asset Management portfolio. This role is responsible for defining the strategic blockchain architecture vision and driving a multi-year roadmap for tokenization, decentralized finance (DeFi), and related technologies.
What You'll Do
- Design Highly Available, Scalable, resilient solutions for applications within the blockchain ecosystem.
- Drive innovation, prototyping, and solution recommendations for DeFi applications.
- Collaborate with key partners in adopting emerging technologies.
- Define the blockchain architecture vision, encompassing on-chain and off-chain components, data, security, and integration.
- Drive a multi-year roadmap for tokenization, DeFi, cross-chain solutions, data platforms, and zero-knowledge adoption.
- Establish governance for smart contracts, data indexing, and interoperability standards across Asset Management and enterprise systems.
- Bridge strategic planning with hands-on execution for critical platform components and accelerators.
- Accelerate high-impact, compliant blockchain use cases in areas like investment operations, digital assets, risk, and distribution.
- Deliver secure, scalable multi-chain platforms (EVM and non-EVM) with audited smart contracts.
- Provide reliable blockchain data ingestion, indexing, querying, analytics, lineage, and governance.
- Optimize architectures to reduce gas fees, latency, operational risk, and total cost of ownership.
- Elevate engineering maturity through patterns, SLAs, KPIs, security posture, and observability.
- Evaluate, prototype, and recommend open-source and vendor technologies and platforms.
- Showcase technology leadership by participating in cross-company initiatives.
What We're Looking For
- BE/MCA degree.
- 15+ years of software and architecture experience.
- 5+ years of blockchain experience, with EVM and at least one non-EVM platform.
- Hands-on experience with blockchain and full-stack development.
- Deep understanding of EVM internals and Solidity, including advanced patterns (upgradeable, diamond, minimal proxy, compliance hooks).
- Expertise in cross-chain and interoperability (LayerZero, Wormhole, CCIP, oracle strategy, bridge risk mitigation).
- Experience in blockchain data engineering (nodes, archive, event decoding, reorg handling, custom indexers, ETL to data lake/warehouse).
- Data stack expertise (Kafka, Flink/Spark, ClickHouse/Snowflake, columnar design, caching tiers, GraphQL/gRPC APIs).
- Proven ability in performance and cost optimization (gas profiling, storage layout, node topology, capacity planning).
- Security and assurance skills (threat modeling, formal verification, Slither, MythX, Echidna, fuzzing with Foundry).
- Knowledge of zero-knowledge and Layer 2 technologies (rollups, prover integration patterns, fraud/validity proof considerations, MEV mitigation).
- Multi-language proficiency: Solidity plus at least one of Rust, Go, Java, Python, or Node.js.
- Enterprise integration experience (PKI/mTLS, IAM, secrets/HSM/KMS, event-driven architectures, API gateway patterns).
- Cloud architecture skills (AWS/Azure networking, container orchestration, DevSecOps CI/CD pipelines).
- Observability and resilience experience (distributed tracing, metrics, log correlation for on/off-chain components).
- Ability to produce formal architecture artifacts (C4, sequence diagrams, data flow, threat and recovery models).
- Strong global stakeholder management and communication skills.
- Experience with ALM tools like JIRA, Confluence, Jenkins, Git.
- Solid experience in Agile methodologies (Kanban and Scrum).
Nice to Have
- Experience with real-world asset tokenization and transfer restriction frameworks.
- Knowledge of wallet/MPC/custody platform integration.
- Advanced data governance expertise (cataloging, lineage, quality, retention policies).
- Financial domain expertise (trading, settlement, NAV, portfolio accounting).
- Privacy-enhancing techniques (confidential computing, selective disclosure).
- Familiarity with accelerator/incubator environments and venture evaluation.
- Experience integrating MPC, threshold signatures, and hardware security modules for key management.
