Software Engineer
Smart Contract Engineer focused on designing, upgrading, and securing core DeFi protocol logic within the Sky ecosystem, bridging governance decisions to on‑chain implementation using Solidity, Ethereum tooling, and rigorous security audits.
Dewiz is an Ecosystem Actor within the Sky Ecosystem (formerly MakerDAO), one of the most battle-tested and capitalized ecosystems in DeFi, historically responsible for pioneering decentralized stablecoins (DAI) and managing billions in on-chain liquidity. As part of Sky’s Endgame architecture , the ecosystem is evolving into a network of specialized, autonomous actors, each responsible for specific verticals such as governance, risk, growth, and protocol execution.
Dewiz sits at the core of protocol execution, you can think of it as:
The team responsible for shipping and upgrading core smart contract logic
The interface between governance decisions and on-chain implementation
A high-trust execution layer , ensuring changes to the protocol are secure, efficient, and aligned with the system’s long-term design
Why This Role Exists
As Sky continues to scale and evolve its architecture (collateral systems, vault mechanics, governance primitives, and new financial instruments), there is an increasing need for:
Highly secure smart contract development
Efficient execution of governance-approved upgrades ("Spells")
Protocol-level innovation across DeFi primitives
This role sits within the Spell Crafting team, responsible for designing, implementing, and deploying the smart contracts that directly shape the evolution of the protocol.
What You’ll Work On
Smart Contract Engineering
Design, implement, and deploy Solidity-based smart contracts powering core protocol functionality
Build and execute governance “Spells” that modify system parameters and logic
Protocol Design & Evolution
Collaborate with ecosystem actors (risk, governance, product) to define new mechanisms
Contribute to the architecture of lending, collateralization, and stablecoin systems
Security & Reliability
Conduct deep audits of smart contracts and protocol changes
Identify and mitigate vulnerabilities (reentrancy, oracle manipulation, etc.)
Maintain production-grade reliability for contracts managing billions in TVL
Performance & Gas Optimization
Optimize contract execution paths for efficiency at scale
Balance cost, complexity, and security trade-offs
System Integration
Integrate contracts with frontends, off-chain systems, and governance tooling
Work closely with tooling around execution pipelines and monitoring
Architecture & Systems Thinking
Contribute to broader system design decisions across the Sky ecosystem
Ensure coherence between protocol layers (governance → execution → state transitions)
Research & Innovation
Stay ahead of emerging standards (ERCs, account abstraction, new DeFi primitives)
Explore new mechanisms for capital efficiency, risk management, and automation
