ROLE OVERVIEW

You will act as the senior technical architect responsible for helping structure and scale a growing ecosystem of operational SaaS products.

You must be capable of making high-level technical decisions independently and understanding how enterprise platforms should operate securely, efficiently, and at scale.

This is NOT a basic coding role.

You will work directly with leadership and existing developers to refine, restructure, optimise, and future-proof platform architecture.

You MUST have proven experience in:

• Multi-tenant SaaS architecture
• Large-scale backend systems

• Audit logs & compliance-grade tracking
• Performance optimisation
• Infrastructure cost optimisation
• Offline sync architecture
• Production deployment environments

You MUST understand:

• AWS / Azure / Google Cloud
• PostgreSQL / MySQL optimisation
• Node.js backend architecture
• WebSocket or real-time event systems
• Scalable authentication systems
• Enterprise security standards
• Docker / containers
• Git workflows
• DevOps principles

Experience with Flutter-based ecosystems is highly advantageous.

YOU SHOULD BE ABLE TO:

• Identify poor architecture immediately
• Refactor systems correctly
• Build scalable SaaS foundations
• Design proper database structures
• Prevent future technical debt
• Lead backend direction
• Guide existing developers technically
• Improve deployment and security standards
• Build systems suitable for thousands of users
• Create enterprise-grade operational platforms

DO NOT APPLY IF:

• You are mainly a WordPress developer
• You only build websites
• You rely heavily on AI to code everything
• You have never scaled a SaaS platform
• You do not understand infrastructure
• You do not understand multi-tenancy
• You cannot work independently
• You require constant supervision
• You lack production deployment experience
• You are a junior or mid-level developer attempting to step up

We are looking for genuine senior-level capability only.

• EmployerCore (HR, Workforce, Time & Attendance)
• PropertyHub (Property & Maintenance Management)
• FixFlow (Standalone Maintenance SaaS)
• Care Evidence (Social Care Compliance Platform)
• VeltroVault (Document & Life Management System)

This is a long-term opportunity with substantial growth potential for the right individual.
