• 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

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

At IOG, we value diversity and always treat all employees and job applicants based on merit, qualifications, competence, and talent. We do not discriminate on the basis of race, religion, color, national origin, gender, sexual orientation, age, marital status, veteran status, or disability status.
