Are you the one?

Starknet is the fastest-growing network in terms of new developers joining the network. Nethermind builds many developer-facing tools that need to work seamlessly in this fast-paced blockchain. This ecosystem needs contributors with quality-mindset, capable of applying their craftsmanship and systematic creativity to improve its components. Do you have what it takes?

Responsibilities:

  • R&D working culture
  • Development of scalable, high availability, and low-latency architectures
  • Implement optimization algorithms to improve code generation and execution efficiency.
  • Collaborate with software engineers and architects to integrate compiler technologies into larger software systems.
  • Analyze and debug compiler-generated code to ensure correctness
  • Contribute to the documentation of compiler design, implementation, and usage.
  • Participate actively in code reviews, providing valuable insights and feedback to peers.
  • Opportunity to work with the top software engineers and research professionals to solve the toughest technical challenges
  • Working with the latest tools and technologies
  • Troubleshooting

Skills:

  • Ability to implement efficient algorithms and design complex data structures
  • Excellent programming skills, Go or Rust preferred but will also consider other tech stacks (e.g. Java, C++)
  • Experience with compiler construction tools such as Lex, Yacc, LLVM, GCC, or similar.
  • Strong understanding of compiler architecture, principles, and optimization techniques.
  • Familiarity with assembly language programming and debugging.
  • Ability to write clean, testable, and maintainable code without over-engineering
  • An entrepreneurial nature, willing to take ownership and run toward problems
  • Several years of experience in software development
  • Awareness of cloud-based computing environments (eg. AWS)
  • Strong computer science background, including knowledge of algorithms, data structures, and operating systems concepts.
  • Effective communication skills, both written and verbal.

Nice to have:

  • Performance and memory optimisations
  • Awareness of blockchain / EVM / TransactionPool / JSON RPC
  • Knowledge of zero-knowledge proofs (ZKPs) and their integration into Starknet or similar platforms.
  • Cryptography
  • Knowledge of parallel programming paradigms and techniques.
  • Experience with dynamic analysis tools for performance profiling and optimization.
  • Understanding of formal methods and compiler verification techniques.
  • Familiarity with virtual machine architectures and execution models

Examples of projects the team has worked on:

  • Transpiler from Solidity to Cairo
  • Virtual Machine in Go for Cairo code
  • Compiler to convert Sierra code to machine code via MLIR and LLVM
  • Integration with elements of Starknet ecosystem (eg. Starknet Blockifier)
