This description is a summary of our understanding of the job description. Click on 'Apply' button to find out more.

Role Description

Blockstream Research is hiring a Research Engineer with deep Bitcoin and Rust expertise to build and deploy Simfony on the Liquid Blockchain.

  • Own Simfony’s Rust-based language development. You will work on building, improving, and refining Simfony as a smart contract language.
  • Implement smart contracts. You’ll recreate existing Bitcoin Script functionality in Simfony and extend functionality using Simplicity, making contracts more expressive and powerful.
  • Collaborate with a small team inside of Blockstream Research to help shape developer use of Simplicity, and its integration into Bitcoin sidechains.
  • Develop, test, and deploy Simfony contracts on Liquid. You’ll explore how Simfony integrates with Bitcoin’s Layer 2 solutions, including Elements and potential future platforms.
  • Work on security and efficiency. You’ll help optimize Simfony contracts for performance and security.
  • Write documentation and educational material. As Simfony grows, developers will need clear examples, tutorials, and best practices to build with confidence.

Qualifications

  • Expertise in Rust.
  • Deep understanding of Bitcoin’s scripting model. You have a strong knowledge of Bitcoin Script, Taproot, Schnorr signatures, SegWit, Miniscript, and Confidential Transactions.
  • Experience with smart contract development, time-locked contracts (HTLCs, vaults, inheritance-based transfers), multi-signature setups, or covenant-based mechanisms.
  • Comfortable working with Bitcoin’s developer tooling. Experience with Bitcoin Core, CLI tools, test environments (Testnet, Regtest), and security testing tools like fuzz testing.
  • Problem solver. You enjoy tackling difficult programming challenges and designing creative solutions for complex problems.
  • A builder’s mindset. You don’t just write code, you design systems that solve real problems.
  • Clear communicator. You can explain complex technical ideas simply, write thorough documentation, and work well with a team.
  • Comfortable with an education component. At least X% of this role involves documentation, teaching, and developer advocacy, helping others understand and build with Simfony.

Requirements

  • Degree in a relevant field, such as Computer Science, Software Engineering, or a related field.
  • Strong grasp of WebAssembly (WASM). Experience working with low-level execution environments or blockchain virtual machines is helpful.
  • Familiarity with other blockchain ecosystems and smart contract platforms. You know about Ethereum (Solidity), Web3, DeFi, DAOs, Bridges, and Oracles, and understand the use cases people are seeking.
  • Experience using and deploying production-grade smart contracts. You’ve seen the challenges, MEV risks, DoS attacks, and syntax errors.
  • Experience in Haskell, or other functional languages is a plus.
  • Knowledge of alternative smart contract paradigms. Familiarity with ZK-proofs, rollups, or novel execution models is a plus.
  • Familiarity with low-level cryptographic libraries. Understanding elliptic curve cryptography, signature schemes, and hash-based cryptographic structures can be beneficial.
