Job description

Who are we?

IOHK is a technology company focused on Blockchain research and development. We are renowned for our scientific approach to blockchain development, emphasizing peer-reviewed research and formal methods to ensure security, scalability, and sustainability. Our projects include decentralized finance (DeFi), governance, and identity management, aiming to advance the capabilities and adoption of blockchain technology globally.

We invest in the unknown, applying our curiosity and desire for positive change to everything we do. By fueling creativity, innovation, and progress within our teams, our products and services are designed for people to be fearless, to be changemakers.

What the role involves:

The primary purpose of this role is to develop high-quality software solutions that meet customer needs. You will be responsible for writing high-quality code for our products. You will work with cutting-edge research and technology. To support you on this challenge, our products have software architects, product managers, project managers, formal methods specialists, and QA test engineers, with whom you must communicate professionally, effectively, and efficiently.

The Plutus Core team is building the core of Cardano’s smart contract functionality on the bedrock of functional programming languages. This interdisciplinary team carries out original R&D and turns the results into production systems. This team has designed and implemented four languages for Cardano smart contracts (Plinth, Plutus IR, Typed Plutus Core, and Untyped Plutus Core) and improved the compiler and runtime with more built-in functions and optimizations, expanding the expressiveness, capability, and security of smart contracts on Cardano. The team has formalized the semantics of Typed and Untyped Plutus Core using Agda, developed novel compilation techniques for data types, and implemented a compiler for compiling Plinth into Untyped Plutus Core, which uses Plutus IR and Typed Plutus Core as intermediate representations. They also implemented evaluators for Typed and Untyped Plutus Core, in Haskell and Agda. They contributed to Cardano ledger updates for smart contracts and published peer-reviewed research.

Coding and Development:

• Write and maintain code in Haskell.
• Use Git for version control, committing often, and submitting small pull requests.
• Write clean, efficient code that meets acceptance criteria and specifications.

Testing and Debugging:

• Write and execute unit, property-based, and integration tests to ensure code quality.
• Identify and fix bugs, including emergency fixes for severity 1 issues.
• Troubleshoot, debug, and upgrade existing software.

Code Reviews and CI/CD:

• Conduct and participate in code reviews to maintain code quality.
• Implement and manage CI pipelines using GitHub Actions, troubleshooting and improving as needed, optionally using Nix.

Software Architecture and Security:

• Design and architect software components.
• Design secure software and perform security analysis.
• Review specifications from architects and formal methods specialists.
• Contribute to algorithm design.

Documentation and Research:

• Write clear software documentation and technical user manuals.
