Your mission:

 * Contribute to defining the architecture vision for complex defence solutions, including stakeholder needs, operational context, system boundaries, and interfaces within broader mission ecosystems.
 * Define, assess, and recommend candidate solution architectures that meet operational expectations, technical constraints, product strategy, cost objectives, and programme schedules.
 * Lead the development of the solution architecture, making informed trade-offs between performance, risk, maturity, interoperability, and affordability, while documenting the associated architectural artefacts and validating lower-level specifications.
 * Support the solution development lifecycle, including engineering coordination, integration strategy, and the establishment of effective co-engineering ways of working across multidisciplinary teams.
 * Ensure the architecture supports Thales' ambitions in delivering mission-ready, interoperable, secure, and scalable defence capabilities.
