Solana PERP DEX: Superis Labs - Software Engineer, Backend

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. 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. What You'll Work On You will design and build the core on-chain and backend systems that power a perpetual exchange, with a focus on correctness, performance, and simplicity. Responsibilities

• Build core exchange logic: markets, users, collateral, fees, order routing
• Implement professional liquidity sources, on-chain matching, margining, liquidation, and risk enforcement
• 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

Requirements

• 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

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

Benefits

• 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
