Skills
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 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.
Build the frontend systems that deliver a professional‑grade perpetual trading experience, with a focus on performance, reliability, and clarity.
- Build the core web trading interface: markets, order entry, positions, balances, charts
- Integrate Solana wallet flows and backend services into real‑time UI systems
- Implement low‑latency data streaming and state management
- Optimize frontend performance for high‑frequency user interaction
- Collaborate closely with designers, backend engineers and protocol engineers on system design
- Write tests and maintain clear documentation
- Own features end‑to‑end from design to production
- 3+ years of professional software development experience
- Strong proficiency with modern frontend frameworks (React, TypeScript, etc.)
- Experience building complex, data‑intensive web applications
- Strong attention to UI/UX detail
- Familiarity with DeFi, trading, or financial applications
- Ownership mindset and comfort in an early‑stage environment
- Strong English communication skills
- Experience building trading interfaces or orderbook‑style UIs
- Experience integrating Solana wallets and transaction flows in web apps
- Familiarity with perpetuals, margin trading, or funding mechanics
- 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
