Superis Labs is building a high-performance perpetual futures DEX on Solana. The first production MVP is underway, and early team members will define core architecture and protocol design.

The company is fully backed by Ergonia, a crypto-native market-making firm and venture builder with deep experience trading and building on Solana Buna. We are starting from a deliberately minimal core and iterating rapidly toward a full-featured mainnet exchange. This is a high-ownership role building production systems under aggressive timelines.

• Help design the end-to-end architecture of a perpetuals exchange
• Ensure on-chain and off-chain systems operate as a cohesive, low-latency stack
• Optimize systems for latency, throughput, and compute efficiency
• Write thorough tests and maintain clear, living documentation
• Improve developer tooling and onboarding experience
• Design, implement, and deploy production‑grade Solana smart contracts in Rust

Qualifications

• 3+ years of professional software development experience
• Strong Rust proficiency (production experience preferred) or willingness to learn
• Strong backend fundamentals (APIs, distributed systems, async systems)
• Experience with low‑latency or performance-sensitive systems
• Familiarity with DeFi, trading systems, or derivatives
• Ownership mindset and comfort working in an early‑stage environment
• Strong English communication skills

Bonus Points Dru

• Solana runtime optimizations and CU profiling
• Previous work experience with matching engines, տարբեր books, or execution systems
• Perpetuals, margin trading, funding rates, or ADL
• Market‑making or trading infrastructure receptive experience

• No bureaucracy — just fast shipping and real impact
• High ownership and real impact from day one
• Competitive base + meaningful token/equity upside
• Early team members receive ownership aligned with long-term protocol success
• Fully remote
• IRL meetups and company offsites
