Long Term Contract 

Role Overview

We are seeking a Senior Engineer – Blockchain Platforms to build and integrate the blockchain infrastructure supporting digital asset custody and tokenization platforms. This hands-on role focuses on Layer-1 blockchain integration, core infrastructure services, wallet engineering, and custody-related blockchain workflows. The engineer will collaborate with custody and security teams to ensure blockchain interactions are secure, reliable, observable, and production-ready.

Key Responsibilities

1. Integrate enterprise platforms with Layer-1 blockchains and evaluate protocols based on custody, scalability, security, and resilience requirements.
2. Design and build blockchain infrastructure services, including indexers, event processors, chain-data APIs, observability tools, and cross-chain components.
3. Develop wallet services and transaction pipelines covering transaction creation, signing, submission, monitoring, and reconciliation.
4. Integrate wallet services with MPC, HSM, key management, and signing platforms.
5. Design for chain-specific conditions such as finality, forks, reorganizations, network congestion, and transaction failures.
6. Develop safe patterns for interacting with smart contracts, token standards, and blockchain networks.
7. Ensure blockchain data pipelines and services are accurate, scalable, testable, observable, and auditable.
8. Support troubleshooting, incident response, failure recovery, and root-cause analysis across distributed blockchain environments.
9. Use generative and agentic AI tools to accelerate protocol analysis, development, testing, documentation, and knowledge sharing.

Qualifications

1. 7+ years of professional software engineering experience.
2. Hands-on experience building or integrating blockchain, cryptocurrency, or distributed ledger systems.
3. Strong understanding of Layer-1 protocols, transaction lifecycles, finality, forks, reorganizations, and event propagation.
4. Experience developing backend services, APIs, event-driven systems, and infrastructure components.
5. Proficiency in Go, Java, Rust, Python, or a comparable programming language.
6. Experience with blockchain indexers, explorers, chain analytics, or on-chain data platforms.
7. Knowledge of wallet architecture, transaction signing, and blockchain submission workflows.
8. Familiarity with smart contracts, token standards, and cross-chain interoperability.
9. Experience integrating with MPC, HSM, key management, or digital asset custody platforms.
10. Strong troubleshooting skills in distributed, asynchronous, and security-sensitive environments.
11. Ability to collaborate effectively across engineering, custody, cybersecurity, risk, and platform teams.
12. Experience using generative or agentic AI tools to support complex software engineering workflows is beneficial.
