About the Role

We are seeking an experienced Core Blockchain Developer to join our team and contribute to the design, development, and optimization of our blockchain protocol and infrastructure. You will work at the foundational layer of blockchain technology, implementing consensus algorithms, cryptographic components, P2P networking, and performance optimizations.

As a Core Blockchain Developer, you will be instrumental in shaping the architecture and capabilities of our blockchain network whether its a new L1 chain, a custom L2, or enhancements to an existing protocol.

Key Responsibilities

  • Design and develop the core components of a blockchain protocol, including consensus, networking, data storage, and virtual machines.
  • Implement and maintain peer-to-peer (P2P) networking layers.
  • Develop and optimize consensus algorithms (e.g., PoW, PoS, DPoS, PBFT, etc.).
  • Write performant, secure, and scalable code in low-level languages (e.g., Rust, Go, C++).
  • Integrate cryptographic algorithms and primitives such as hashing, digital signatures, and zero-knowledge proofs.
  • Contribute to the implementation of virtual machines (e.g., EVM, WASM).
  • Analyze and optimize protocol performance, latency, and security.
  • Review, audit, and test code for correctness, security, and performance.
  • Participate in research and exploration of new blockchain architectures and standards.
  • Collaborate with DevOps, smart contract, and dApp teams to ensure smooth integrations across the stack.

Required Skills & Qualifications

  • Strong programming experience in Rust, Go, C++, or similar low-level systems languages.
  • Deep understanding of blockchain architecture and protocols.
  • Experience implementing or modifying consensus algorithms (PoS, PoW, etc.).
  • Knowledge of peer-to-peer networking, distributed systems, and decentralized storage.
  • Familiarity with cryptographic primitives: Merkle trees, signatures, encryption, ZKPs.
  • Experience with performance profiling, memory management, and multi-threaded development.
  • Understanding of blockchain virtual machines (e.g., EVM, WASM).
  • Proficient with Git, CI/CD, and modern development practices.

Nice-to-Have Skills

  • Experience contributing to major blockchain protocols (e.g., Ethereum, Cosmos, Substrate, Solana, Tender mint).
  • Familiarity with frameworks like Substrate Tender mint, or Cosmos SDK.
