Description 

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. 

● Commitment to designing systems that are secure, performant, and cost-efficient.

Desirable Skills 

● Deep experience with multiple programming languages and frameworks (e.g., ● JavaScript/TypeScript, Node.js, React, Java, .NET, Python). 

● Strong knowledge of cloud-native architectures (AWS, GCP, Azure) and containerisation (Docker, Kubernetes). 

● Experience with data platforms, integration patterns, and API-first design (REST, GraphQL, gRPC). 

● Familiarity with CI/CD, DevOps, and Infrastructure-as-Code practices. ● Understanding of security standards, compliance (GDPR, SOC2), and enterprise IT constraints. 

● Ability to design for scalability across global markets and multi-tenant environments. ● Strong knowledge of design systems and front-end frameworks, ensuring alignment between presentation and infrastructure. 

● Experience leading architectural reviews, trade-off analysis, and decision records. ● Ability to mentor teams and establish communities of practice around architecture. ● Awareness of emerging technologies (AI, serverless, edge computing) and their practical application. 

On any given day you might 

● Define architecture blueprints and technical roadmaps for enterprise projects. ● Partner with product owners and business stakeholders to align architecture with strategic goals. 

● Make key technology selection decisions, balancing innovation with long-term maintainability. 

● Review system designs, ensuring alignment with principles of security, scalability, and performance. 

● Support engineering teams with hands-on prototyping and technical problem solving. ● Facilitate architectural reviews and communicate trade-offs to both technical and non-technical audiences. 

● Collaborate with designers to ensure UI/UX and architecture integrate seamlessly. ● Influence enterprise customers, helping them modernise platforms and adopt composable, headless, or cloud-native approaches. 

● Establish coding standards, architectural patterns, and governance processes. ● Share thought leadership internally and externally, positioning Co. as a trusted Advisor.

You bring 

● 7+ years of software development and architecture experience. 

● Expertise in designing cloud-native, distributed systems. 

● Proven success in leading technical decisions across multi-team programmes. ● Strong cross-functional collaboration and customer-facing skills.
