Atlas Axis serves as the Core Council Governance Operations (GovOps) function for Sky. We are responsible for building and maintaining the Atlas, the comprehensive rule system that defines how every actor in the Sky ecosystem interacts, deploys capital, manages risk, and coordinates under verifiable constraints. Our mandate spans both governance and technical infrastructure:

  • Codifying the rules that govern Agent behaviour and capital deployment.
  • Developing the frameworks and tooling that enable new financial primitives to be introduced safely.
  • Ensuring system-wide safety, transparency, and operational integrity as Sky scales.
  • Supporting other ecosystem teams in building infrastructure that aligns with Sky's risk, governance, and economic standards.

Atlas Axis sits at the centre of Sky's emerging decentralized economy — shaping how Agents collaborate, transact, and deploy capital across a multi‐billion‐dollar ecosystem.

Role Overview — Lead Spell Crafting Engineer

Spell Crafting refers to the development of highly secure, reliable, and verifiable Solidity smart contracts that encode the rules, constraints, and capabilities of the Sky ecosystem. As the Lead Spell Crafting Engineer, you will be responsible for architecting and building the foundational smart contract infrastructure that defines how capital flows, how Agents interact, and how governance rules are enforced. This is a deeply technical, high‐leverage role with ownership over critical‐path code. You will build and lead a team of Spell Engineers whose mission is to deliver mission‐critical, rigorously verified smart contracts that safeguard Sky's financial system. This is a role for someone hungry for outsized impact, direct ownership, and influence over the next generation of decentralized financial infrastructure.

Key Responsibilities

  • Architect & Build Core Smart Contract Infrastructure
  • Design and implement highly secure Solidity contracts ("spells") for capital flows, Agent permissions, governance logic, and risk constraints.
  • Develop modular and extensible components that integrate with Sky Core.
  • Apply deep EVM‐level reasoning, gas optimization, and safety‐by‐design principles.
  • Lead & Scale the Spell Engineering Function
  • Build, mentor, and guide a team of Spell Engineers.
  • Define coding standards, testing practices, audit readiness processes, and documentation norms.
  • Set the technical bar for quality, correctness, and resilience.
  • Own Security, Verification & Audit Processes
  • Lead internal reviews, threat modeling, and formal verification planning.
  • Collaborate closely with external auditors and internal security stakeholders.
  • Ensure system safety across all deployed spells and contract upgrades.
  • Work Cross‐Functionally Across Governance, Risk & Research
  • Translate the Atlas (rulebook) into executable logic.
  • Partner with governance, economic researchers, and risk engineers to define safe system behaviour.
  • Influence the Long‐Term Architecture of Sky Core
  • Make foundational architectural decisions that shape how Agents operate and scale.
  • Ensure extensibility, upgradeability, and robustness of the system as new Agents, primitives, and markets emerge.

Why Join Atlas Axis

  • Work on one of the most ambitious decentralized financial systems ever attempted.
  • Own the core smart contract logic that governs a multi‐billion‐dollar ecosystem.
  • Operate at the intersection of governance, engineering, economics, and AI‐driven finance.
  • Help define how autonomous Agents deploy capital safely and efficiently.
  • Join a small, elite, high‐trust team where your decisions have ecosystem‐wide impact.
  • Get the rare opportunity to completely redefine financial infrastructure from first principles.

What Great Looks Like

  • Expert‐level Solidity and smart contract architecture experience.
  • Knowledge of EVM internals and gas optimization techniques.
  • A strong security mindset, ideally with experience in formal verification and audit processes.
  • Experience building or contributing to mission‐critical DeFi/L1/L2 systems.
  • The ability to lead technical teams and establish high engineering standards.
  • Clear, rigorous thinking with an appreciation for governance, risk, and economic constraints.
