Partner Chains empowers developers and validators to create optimized blockchains without network or technology stack lock-in, fostering a new era of interoperable and scalable solutions.

What the role involves:

As a Software Engineer at IOG, you are responsible for writing high-quality code for our products. You have the exciting challenge of working with cutting-edge research and technology with a focus on the market's needs. 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.

• Follow agile software development practices
• Work with teams across multiple time zones
• Work independently on software development tasks
• Be proactive and require minimal supervision or mentoring to complete tasks
• Review specifications produced by architects and formal methods specialists
• Contribute to the design of algorithms
• Write clean, straightforward, efficient code that satisfies previously agreed acceptance criteria and specifications
• Commit often and submit small pull requests frequently
• Cover your code with unit, property and integration tests when applicable
• Review the pull requests of your team mates
• Fix bugs in your own code and in legacy code from others
• Be available for emergency fixing of severity 1 issues on deployed products
• Integrate software components and third-party libraries
• Verify and deploy programs and systems
• Troubleshoot, debug and upgrade existing software
• Write documentation for the code
• Write technical user manuals
• Be knowledgeable of distributed and concurrent computation
• Be knowledgeable of cryptography

Requirements

Who you are:

• A minimum of 5 years of development experience (Solidity, Rust or TypeScript)
• Experience working with Git
• Practical experience with Agile software development methods
• Knowledge of functional and object-oriented programming paradigms
• Degree in Computer Science is desirable but not essential
• Be knowledgeable of cryptography and usage in blockchains
• Demonstrated proficiency in programming languages such as Solidity, Rust, and TypeScript
• Design, develop, and deploy smart contracts on multiple blockchains
• Create and optimize on-chain program architectures for efficiency, scalability, and security
• Ensure all smart contracts are rigorously tested and audited to meet high security standards
• Experience working with smart contracts and blockchain technology essential
• Experience with web services development and RESTful APIs
• Distributed systems and network development
• A track record of delivering software projects from start to finish
• Proficiency in software development best practices, including design, implementation, testing, and debugging
• Write idiomatic code that satisfies the acceptance criteria of a given task
• Write tests (unit tests, property tests) that provide sufficient and non-superfluous efficient code coverage.
• Document code and APIs concisely and unambiguously
• Break down tasks into sub-tasks that are completable in a short amount of time and report completion as required by managers
• Pragmatically adhere to software engineering principles (modularity, incremental development, no premature optimization, no feature creep, no speculative generality, ...)

Are you an IOGer?

Do you find yourself questioning the status quo? Do you tinker with ideas and long to turn those ideas into solutions? Are you able to spark thoughtful debates, bringing out the inquisitiveness in others? Does the promise of continuously growing excite you? Then get ready to reimagine everything you thought wasn’t possible because that’s what it means to be an IOGer - we don’t set limits, we break them.

• New starter package to buy hardware essentials (headphones, monitor, etc)
• Competitive PTO
