Description du poste

This company is a Web3 player offering a unified API to access all on‑chain liquidity across major blockchains in order to simplify multi‑chain DeFi for traditional financial institutions, fintechs and service providers, for best price same‑chain and cross‑chain swaps.

They are looking for a Backend Developer with a dedicated focus on integrating Hyperliquid functionalities into their API platform. This role is backend‑only (no frontend or design work required) letting you shape core integrations at the infrastructure layer.

Please note: You must be located in the EMEA region. Your application will not be considered otherwise.

This is a remote role but you must be located in the EMEA regions (or potentially APAC region overlapping with EU hours).

Missions

• Extend the company’s API stack to include Hyperliquid ecosystem projects and feature set
• Collaborate closely with the Expansion PM and other backend engineers to improve integrations, routing, and user flows; help evaluate new opportunities for feature extension.
• Ensure robust, high‑quality backend code, focusing on scalability and reliability for same‑chain and cross‑chain trading.
• Participate in code reviews, system design, and documentation.

Technical ecosystem :
Backend : Typescript, EVM and integration patterns
Hyperliquid : builder codes (spot, perps), HIP‑3, pre‑compiles, and HyperEVM
Programmatic trading : TWAP, perps, orderbooks
Crypto : Solana, Bitcoin (Nice to have)

Requirements

The company prioritizes candidates who show genuine excitement for Hyperliquid and demonstrate technical familiarity with its protocols. Expect conversations where you can showcase prior Hyperliquid‑related projects and discuss ideas for future integration work.

Prior Hyperliquid work experience IS NOT a requirement per se but the employer will test your understanding through interview discussions and portfolio review.

Interest in Hyperliquid and its protocols, eager to help the company distribute programmatic trading features (e.g., TWAP, perps) to the broader DeFi ecosystem through performant backend systems.

Familiarity with Hyperliquid’s architecture: You understand builder codes (spot, perps), HIP‑3, pre‑compiles, and HyperEVM at a design level and keep up with evolving documentation.

Hyperliquid focus: You are passionate about the Hyperliquid ecosystem and be able to demonstrate your familiarity with the ecosystem — past projects or self‑driven exploration are valued.

Orderbook fundamentals: You grasp the mechanics of orderbooks and are comfortable working with programmatic trading features.

Backend focus: Solid backend engineering background, especially with EVM and integration patterns; front‑end or modal design work is not expected.

TypeScript proficiency: Experience building scalable APIs and backend systems in TypeScript.

Independence: Can drive integrations and new feature proposals with minimal oversight, collaborating effectively in a remote‑first team.

Cross‑chain experience: Experience with bridges and backend infrastructure supporting a multi‑chain environment is highly valued.

Bonus: Familiarity with Solana, Bitcoin, or mobile backend development.
