About VistralNova

VistralNova is a technology company building developer tools, game systems, AI-powered experiences, and digital infrastructure for modern interactive products. Our work brings together software engineering, game design, artificial intelligence, and asset-ready infrastructure to help teams create products that are practical, scalable, and easier to trust.

We are evolving toward a flexible technical foundation aligned with Polkadot and PVM-based architecture. Our team values clean architecture, practical execution, strong engineering standards, and long-term product quality.

About The Role

The Senior Solidity / Rust Developer will design and build secure on-chain systems for VistralNova's games, digital asset platforms, and developer infrastructure. This role focuses on smart contracts, digital asset logic, marketplace systems, reward distribution, and on-chain-connected product mechanics. You will work closely with backend engineers, game developers, and product teams to ensure that assets, ownership records, and transaction flows are reliable, efficient, and secure. This role requires strong smart contract engineering skills, practical crypto knowledge, and the ability to write production-ready code for real user-facing systems.

What You'll Do

• Develop secure and gas-efficient smart contracts for in-game assets, marketplaces, and reward systems.
• Build on-chain logic for ownership, transfers, staking, rewards, and game-related transactions.
• Write clean, tested, and maintainable Solidity and Rust code.
• Review smart contracts for security risks, edge cases, and performance issues.
• Work with backend and frontend teams to integrate smart contracts into the platform.
• Support deployment, testing, documentation, and contract upgrade planning.
• Help define technical standards for on-chain and digital asset systems.

What We Look For

• Strong experience with Solidity and smart contract development.
• Practical experience with Rust for on-chain, backend, or protocol-level systems.
• Understanding of smart contract security, gas optimization, and common vulnerabilities.
• Experience building NFT, marketplace, staking, reward, or digital asset systems.
• Ability to write well-tested production-grade code.
• Strong debugging, problem-solving, and code review skills.
• Good communication with backend, frontend, and product teams.

Nice to Have

• Experience with digital asset platforms, NFT marketplaces, or digital ownership systems.
• Familiarity with Polkadot, Substrate, Ink!, or cross-chain infrastructure.
• Experience with smart contract audits or security-focused development.
• Experience working in a fast-paced startup environment.
