Senior Software Engineer (Prototype) - Creative Engineering
Who are we? IOG, 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: As a Senior Software Engineer, you are responsible for improving how IOG builds and maintains software, alongside actively contributing to product development. Senior Software Engineer is responsible for the quality of engineering practices within a team. Senior Software Engineers work across teams to identify cross-team improvements for IOG by (for example) sharing code, removing complexity or implementing new practices. As a senior member of the team you are expected to mentor and grow other software engineers and act as a go-to person within the team and the wider organisation across multiple codebases and languages. Advocates for and models great quality with proactive actions, and tackles difficult and subtle system issues Uses systematic debugging to diagnose all issues within a set of related domains and leads in fostering a culture of observability and monitoring across several teams Regularly works across teams to build a culture for iterative, autonomous development and future scaling. Is a technical and prioritisation leader across a set of related team's domains, consistently pushing boundaries and exploring gaps in understanding. Is a go-to within the team and the wider organisation across multiple codebases and languages. Be proactive and require minimal supervision or mentoring to complete tasks Review specifications produced by architects and formal methods specialists Lead the design of components and their interactions 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 Write documentation for the code Write technical user manuals Requirements Who you are: Degree in Computer Science is desirable but not essential 7+ years of software engineering experience in the required language ( Haskell, Javascript, Scala, Rust) Experience working with Git and Git workflow Practical experience with Agile software development methods Knowledge of functional and object-oriented programming paradigms Ability to understand project needs, objectives and timescales to feed into planning and setting deadlines for a specific stream. Clearly articulates new issues, suggests changes to management for implementation. 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 Provide detailed guidance on the work to be done, assist with task assignments and deliver deep reviews and feedback on the work. Pragmatically adhere to software engineering principles (modularity, incremental development, no premature optimization, no feature creep, no speculative generality, ...) Specialist Skills Advanced proficiency in multiple programming languages and functional paradigms, with the ability to select the most effective tools for prototyping and proof-of-concept work. Expertise in at least one system programming language (e.g., Rust, C++), with strong performance optimisation and debugging skills. Proficiency in functional languages (e.g., Haskell, OCaml, F#) and ability to apply functional programming principles in complex, production-grade prototypes. Familiarity or experience with formal specification languages (e.g., Lean, Coq, TLA+) to model and verify protocol behaviour when needed. Strong theoretical grounding in computer science, including algorithms, data structures, concurrency models, and distributed systems design. Comprehensive understanding of blockchain technology, including consensus mechanisms, applied cryptography, networking protocols, and smart contract frameworks. Proven self-direction, with the ability to independently identify problems, explore novel solutions, and rapidly adopt emerging tools and techniques. Ability to design and document high-level architecture and system specifications for experimental or prototype systems, communicating trade-offs and assumptions clearly. Proficient in reading and synthesising scientific research papers, translating theoretical concepts into practical prototypes. Skilled in developing complex prototypes that demonstrate and validate new features, protocols, or architectural approaches, including integration of multiple technologies. Benefits Remote work Laptop reimbursement New starter package to buy hardware essentials (headphones, monitor, etc) Learning & Development opportunities Competitive PTO At IOG, we value diversity and always treat all employees and job applicants based on merit, qualifications, competence, and talent.
