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

Requirements

Deep expertise in Solidity and the EVM

Strong understanding of DeFi primitives (lending, AMMs, collateral systems, stablecoins)

Proven experience with smart contract security and auditing

Hands-on experience with gas optimization and performance tuning

Familiarity with tools such as Foundry, Hardhat, Remix, Ganache

Engineering Mindset

Ability to reason about complex financial systems

Strong ownership and ability to operate in high-autonomy environments

Experience collaborating across distributed / async teams

Testing & Quality

Experience writing robust unit + integration tests

Familiarity with frameworks like Mocha, Chai, or Foundry equivalents

Communication

Clear communicator with the ability to articulate technical trade-offs

Comfortable working in a pseudonymous, remote-first environment

Bonus Points

Contributions to open-source DeFi or protocol-level projects

Experience with multi-chain ecosystems (Solana, Cosmos, etc.)

Exposure to zero-knowledge systems (ZK-rollups, zk-SNARKs)

Previous experience working within a DAO or decentralized org

Familiarity with MakerDAO / Sky architecture (MCD, DSS, governance flows)

Why Join Dewiz

Direct Impact on a Top DeFi System
