Senior Backend Engineer - Rust and Go

Tothemoon is a user-centric, multi-service digital assets trading platform with its own high-performance trading engine and microservice-based architecture, focused on security, reliability, and low-latency execution.

We operate globally, building infrastructure and products at the intersection of trading, DeFi, and blockchain technology.
Our engineering culture is deeply technical — we work close to the core: performance, consistency, and protocol-level logic.

Currently, we are launching a new protocol-grade product — a native perpetual DEX deeply integrated into our own EVM-compatible blockchain.

We are looking for a Senior Backend Engineer with strong Rust expertise and working knowledge of Go to join our core engineering team.

You will work on the heart of the system:

• trading engine

• order execution and settlement

• risk management logic

• integration with EVM and blockchain infrastructure

This role is for an engineer who enjoys building complex systems from scratch, understands how blockchains work internally, and is comfortable owning critical backend logic.

• Develop and optimize a high-performance trading engine (primarily Rust, partially Go)

• Implement and maintain:

  • order book

  • matching engine

  • risk management logic

• Work with cryptographic primitives:

  • Merkle trees

  • digital signatures

  • cryptographic proofs

• Integrate trading logic with EVM-compatible blockchain infrastructure

• Participate in architecture design and core technical decisions

• Ensure performance, correctness, and reliability of mission-critical systems

• Languages: Rust (primary), Go (secondary), Solidity

• Blockchain: EVM-compatible chain, L1/L2 infrastructure

• Core systems: Trading engine, settlement layer, protocol-level logic

• Cryptography: Hashing, signatures, Merkle proofs

Must-have:

• Strong production experience with Rust

• Basic to intermediate Go knowledge (reading, modifying, writing services)

• Understanding of Solidity and EVM internals

• Experience with blockchain systems (L1, L2, rollups, bridges)

• Solid grasp of cryptography fundamentals

• 3+ years of backend engineering experience

• Ability to independently navigate and understand complex systems

• Experience with trading systems, matching engines, or HFT

• Hands-on experience with DeFi protocols, especially perpetual DEXs

• Knowledge of zero-knowledge technologies (SP1, Plonky2, Risc0, etc.)

• Understanding of financial instruments

• Product company with real ownership and impact

• Direct influence on architecture and core protocol decisions

• Senior engineering team and fast decision-making

• Deep exposure to trading and blockchain infrastructure

• Minimal bureaucracy, maximum focus on engineering

• Compensation: discussed individually based on experience

• Work format: fully remote

• Growth: opportunity to grow together with a protocol-level product
