Senior DevOps Engineer

We are building an enterprise-grade blockchain custody platform powered by advanced Multi-Party Computation (MPC) Threshold Signature Scheme (TSS). Our solution provides institutional-grade security for digital asset custody through distributed key management technology — designed for the security requirements of banks, funds, and Web3 institutions.

Core platform features

• •2/3 threshold signature distribution across isolated key nodes
• •Multi-chain support: Bitcoin, Solana, EVM-compatible chains (Ethereum, BNB Chain, Avalanche, Arbitrum, Polygon, etc.), and TRON
• •Hardware wallet integration: Ledger and Trezor
• •Secure key management: TSS nodes distributed across isolated environments with HSM integration

Infrastructure & Environment Management

• •Design, build, and maintain secure, highly available AWS environments using Infrastructure as Code (Terraform / CDK)
• •Set up and manage on-premise TEE infrastructure for secure MPC key computation
• •Deploy and maintain all critical components: MPC TSS nodes (BTC, SOL, EVM, TRON), backend API servers, frontend web application, and blockchain full nodes

Blockchain Infrastructure

• •Configure and monitor full node synchronization for Ethereum and other supported chains
• •Manage RPC endpoints and load balancing across multiple nodes
• •Ensure high availability of blockchain connectivity with automated failover and health checks

CI/CD & Deployment Automation

• •Design and maintain end-to-end CI/CD pipelines using GitHub Actions or GitLab CI
• •Implement blue-green and canary deployment strategies for zero-downtime releases
• •Provide self-service build, test, and deployment tooling for the development team

Monitoring & Observability

• •Build and maintain monitoring, logging, alerting, and tracing systems (Prometheus, Grafana, ELK Stack, Jaeger)
• •Monitor all layers: AWS infrastructure, on-prem TEE nodes, blockchain nodes, MPC computation, and application performance
• •Maintain SLA commitments with proactive alerting and incident response

Security & Compliance

• •Enforce strict IAM, network segmentation, and zero-trust principles across both cloud and on-prem environments
• •Integrate HSM/KMS for secure key management and MPC TSS operations
• •Conduct regular security scans, vulnerability assessments, and penetration testing
• •Manage SSL/TLS, Nginx reverse proxies, and firewall rules

High Availability & Disaster Recovery

• •Design and implement cross-AZ and cross-environment disaster recovery plans
• •Execute regular DR drills and maintain runbooks
• •Maintain 99.9%+ uptime for all critical wallet services

• •Direct experience operating Ethereum, Bitcoin, or other blockchain full nodes
• •Familiarity with Web3 technologies, smart contracts, or DeFi protocols
• •Understanding of MPC, cryptographic key management, or HSM integration
• •Experience with service mesh technologies (Istio, Linkerd)
• •Chaos engineering or fault injection testing experience
• •Experience with HashiCorp Vault, AWS Secrets Manager, or similar secrets management tools
• •Familiarity with Redis, TimescaleDB, or InfluxDB
• •Security certifications (CISSP, AWS Security Specialty, or equivalent)
• •Experience with multi-cloud or hybrid cloud architectures

• •5+ years of DevOps, SRE, or cloud infrastructure engineering experience with large-scale distributed systems
• •Expert-level knowledge of AWS and its managed services
• •Deep hands-on experience with Docker and Kubernetes in production environments
• •Proficiency with GitHub Actions or GitLab CI/CD
• •Strong scripting or programming ability in at least one of: Go, Python, or Shell
• •Solid Linux administration experience (Ubuntu / RedHat)
• •Strong understanding of networking: firewalls, SSL/TLS, load balancing, DNS
• •Hands-on experience with Prometheus, Grafana, or equivalent monitoring solutions
• •Excellent technical documentation and cross-team communication skills
