Our Software Architects are the strategic thinkers and technical leaders. They design, validate, and guide the delivery of enterprise-grade systems that balance innovation, performance, scalability, and cost efficiency. 

 Software Architects work at the intersection of business strategy and technical execution. They collaborate across engineering, product, and design teams to define architecture blueprints, select technologies, and ensure systems evolve in alignment with customer goals. Architects are hands-on, often prototyping solutions and coaching teams, while also trusted to influence executives on technical direction. Here’s what you should know if you want to be a Software Architect at 

Requirements 

The ideal person 

● Proven track record in architecting and delivering large-scale, distributed software systems. 

● Expertise in modern architectural patterns: microservices, event-driven systems, composable commerce, headless architectures. 

● Ability to translate business strategy into actionable technical roadmaps and system designs. 

● Strong leadership skills: guiding engineering teams, mentoring individuals, and setting technical standards. 

● Excellent stakeholder management and communication skills, from engineers to C level.
