Full Stack Developer jobs in United Kingdom

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.

• Ownership mindset and comfort working in an early‑stage environment
• Strong English communication skills
