About this Senior Blockchain Engineer role at Getmidas
What You'll Do
Design and develop scalable, secure, and reliable blockchain infrastructure that handles real users and real money
Own the architecture and full lifecycle of blockchain transactions, from initiation and signing to execution, confirmation, reconciliation, and recovery
Build and evolve wallet, custody, key management, and transaction infrastructure across on-chain and off-chain systems
Design integrations across different blockchain networks, architectures, consensus models, and transaction models
Develop and integrate smart contracts where applicable, including EVM-compatible ecosystems
Build production-grade solutions for DeFi use cases such as staking, liquidity pools, DEX integrations, and other on-chain financial workflows
Take end-to-end ownership of complex blockchain systems, including security, resiliency, observability, incident response, and operational excellence
Drive architectural decisions and technical direction by balancing security, scalability, reliability, maintainability, and development velocity
Identify technical risks early and design systems that remain safe and recoverable under failure scenarios
Collaborate closely with product, business, security, and engineering teams to turn ambiguous requirements into robust technical solutions
Lead technical discussions, design reviews, and architectural decisions within the team
Mentor engineers through technical guidance, code reviews, feedback, and knowledge sharing
Leverage modern engineering tools, including AI-assisted development, while maintaining high standards for code quality, security, and engineering rigor
What You'll Bring
Strong software engineering experience with a proven track record of designing and operating complex production systems
Deep hands-on experience building and operating production-grade blockchain infrastructure
Strong understanding of blockchain architecture across different ecosystems, including consensus mechanisms, transaction models, finality, reorgs, fees, and network-specific behavior
Experience working with multiple blockchain networks and protocol models rather than a single ecosystem or virtual machine
Strong understanding of wallet architecture, custody models, key management, transaction signing, and blockchain transaction lifecycles
Hands-on experience with HSMs and secure key management infrastructure
Experience with MPC-based custody systems or custody platforms such as Fireblocks is a strong plus
Strong understanding of cryptographic signing workflows, key security, access controls, and security boundaries in production systems
Experience developing, deploying, and operating smart contracts; Solidity experience is a strong plus
Experience with DeFi protocols or use cases such as staking, liquidity pools, DEXs, or similar on-chain financial systems
Strong understanding of both on-chain and off-chain architectures and the trade-offs between them
Strong knowledge of distributed systems, asynchronous processing, idempotency, failure recovery, and data consistency
Experience operating critical production systems with monitoring, alerting, observability, incident response, and post-incident improvement practices
Ability to make sound architectural decisions and reason clearly about trade-offs across security, scalability, reliability, operational complexity, and delivery speed
Ability to independently navigate high-ambiguity problems and drive them from initial concept through production
Strong sense of ownership, accountability, and responsibility for production outcomes
Strong communication skills and the ability to influence technical decisions across teams
Willingness to mentor other engineers and raise the technical bar of the team
Ability to use AI-assisted development tools effectively while maintaining sound engineering judgment and security standards
