As a Technical Architect at IOG, you take ownership and are accountable for the technical decisions of a product. You are responsible for designing solutions (products, components, features, libraries, ...) that satisfy functional and non-functional requirements driven by the needs of users of our products. To this aim, you must interact with the product managers, provide feedback on the satisfiability of requirements, present various alternative solutions for satisfying the requirements and provide a critical and impartial analysis of the pros and cons of the alternatives. You must also provide technical leadership and oversight to the development teams and delegate architecture tasks effectively and responsibly to the teams to avoid both efficiency bottlenecks and architectural disagreements. You must be pragmatic about technical debt and willing to make difficult compromises in the architecture to deliver minimum viable products within reasonable amounts of time.

IOHK is a research and development, innovation-driven company. As a Technical Owner at IOG you will be responsible for ensuring all feature requests and the product roadmap are aligned with the system's long-term stability, extendability, maintainability, and security while ensuring the development process is sustainable and efficient.

You will collaborate with the Product Owner, the technical leads, and our researchers to turn user needs into technical requirements and ensure that those are feasible under all technical constraints on the system. In addition, you will feed work items necessary to keep the system maintainable and stable into the roadmap and ensure that they are properly prioritized.

Working with cross-functional teams, you will observe and consult on their development process and team structure to keep it sustainable, efficient, and aligned with the product needs.
