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.
