Smart Contract Engineer / Spell Crafting - Dewiz
from 🌏 Worldwide
Dewiz is anEcosystem 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’sEndgame 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 forshipping and upgrading core smart contract logic
The interface betweengovernance decisions andon-chain implementation
Ahigh-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 theSpell Crafting team,responsible for designing, implementing, and deploying the smart contracts thatdirectly 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
Deep expertise inSolidity and the EVM
Strong understanding ofDeFi primitives (lending, AMMs, collateral systems, stablecoins)
Proven experience withsmart contract security and auditing
Hands-on experience withgas optimization and performance tuning
Familiarity with tools such asFoundry, Hardhat, Remix, Ganache
Engineering Mindset
Ability to reason aboutcomplex financial systems
Strong ownership and ability to operate inhigh-autonomy environments
Experience collaborating acrossdistributed / async teams
Testing & Quality
Experience writing robust unit + integration tests
Familiarity with frameworks likeMocha, Chai, or Foundry equivalents
Communication
Clear communicator with the ability to articulate technical trade-offs
Comfortable working in apseudonymous, remote-first environment
Bonus Points
Contributions toopen-source DeFi or protocol-level projects
Experience withmulti-chain ecosystems (Solana, Cosmos, etc.)
Exposure tozero-knowledge systems (ZK-rollups, zk-SNARKs)
Previous experience working within aDAO or decentralized org
Familiarity withMakerDAO / Sky architecture (MCD, DSS, governance flows)
Why Join Dewiz
Direct Impact on a Top DeFi System
You’ll be working on infrastructure that secures and movesbillions in capital, shaping how decentralized finance evolves.

This is not feature work, you’ll operate at thecore protocol layer, influencing how the system behaves at a fundamental level.
Unique Organizational Model
Pseudonymous collaboration
High autonomy, low bureaucracy
Direct alignment with decentralized values
Front-Row Seat to Sky’s Endgame
Be part of one of the most ambitious transformations in DeFi, moving from a monolithic DAO to amodular, AI-augmented, actor-based system
Growth & Technical Depth
Work alongside engineers and researchers pushing the boundaries of:
Stablecoin design
Governance systems
On-chain execution infrastructure
