Solana Perp DEX

Ergonia is a crypto-native market-making and venture-building firm with deep roots in trading and infrastructure on Solana. We are one of the largest and most sophisticated participants in the ecosystem and now we’re building a next-generation perp DEX on Solana.

We’re looking for a CTO, a high-conviction, technical leader who thrives in the trenches, building and scaling protocol architecture from zero to one. You’ll help shape the next evolution of decentralized trading with a team deeply embedded in Solana’s market, liquidity, and infrastructure landscape.

Technical Leadership & Architecture

• Define, own, and evolve the end-to-end technical vision for a next-generation perpetual DEX on Solana.
• Architect and build core protocol components, including smart contracts, matching and risk engines, and off-chain infrastructure.
• Ensure performance, security, and scalability through strong system design and robust engineering practices.

Execution & Product Delivery

• Drive the product from concept to mainnet: MVP build, audits, deployment, and iterative scaling.
• Collaborate with product, trading, and design teams to rapidly experiment, refine, and deliver features that achieve product-market fit.
• Integrate seamlessly with key Solana ecosystem partners: oracles, liquidity providers, and tooling protocols.
  

Innovation & Ecosystem Engagement

• Stay ahead of advancements in Solana, DeFi infrastructure, and performance engineering.
• Lead R&D on liquidity models, execution architecture, and risk systems that push the limits of decentralized trading.
• Engage with open-source contributors, auditors, and the broader Solana community to strengthen the protocol and brand.

Qualifications

• Proven experience as CTO, Technical Co-Founder, or Lead Engineer in DeFi, trading, or high-performance fintech.
• Deep understanding of Solana architecture, Rust, and smart contract design.
• Experience building low-latency trading systems or DeFi protocols.
• Strong grasp of DeFi market structure, perpetuals, and liquidity mechanics.
• Demonstrated ability to hire, scale, and lead high-performing technical teams.
• High integrity, deep technical curiosity, and passion for building at the edge of decentralized finance.

Bonus Points

• Prior experience launching or contributing to a DEX, perpetual protocol, or trading platform.
• Familiarity with MEV, orderbook-based architectures, or risk engines.
• Contributions to open-source projects or public technical work in the Solana ecosystem.

• Competitive equity and token package.
• Opportunity to shape a flagship Solana-native DEX from inception.
• Deep backing from a leading trading firm with Solana-native infrastructure and venture-building team support.
