Report to the CEO, influence company strategy, shape both technical and business direction!
The Role
We are seeking a hands-on technical leader who can do two things exceptionally well:
- Rebuild a mission-critical enterprise web platform from the ground up, using AI-accelerated development
- Build an engineering capability designed to scale rapidly over the next 12–18 months
This is a true player-coach role. For the first 6 months, you will personally lead architecture and delivery with a lean engineering team. A separate product-focused engineering pod currently driving mobile growth will transition under your leadership around month 6.
You will report directly to the divisional leadership team and operate as part of the senior leadership group.
The Challenge (and Opportunity)
The business currently operates:
- A modern mobile application acting as the primary growth engine
- A legacy monolithic web platform serving enterprise clients
Rather than incrementally modernising the legacy system, the organisation is investing in a new cloud-native, API-first web platform, designed for long-term scalability and deep synchronisation with its mobile products. This role owns that transformation end-to-end.
Your Missions
- Mission 1: Architect and deliver the web platform rebuild
- Personal accountability for architecture, critical technical decisions, and delivery
- Hands-on leadership with a small, high-impact team
- Mission 2: Maintain operational stability
- Ensure continuity of the legacy web platform for enterprise clients
- Mission 3: Consolidate engineering leadership
- Inherit an existing mobile-focused engineering pod (lead engineer + team)
- Unify web and mobile engineering under one leadership structure
- Balance platform completion with ongoing mobile delivery
- Mission 4: Strengthen security and compliance foundations
- Improve authentication, authorisation, and vulnerability management
- Build enterprise-grade security into all applications
The Technical Reality
Team size: 8 engineers (including QA), growing to ~12 within 6 months
Engineering practices: CI/CD, testing, observability, and incident response require modernisation
Architecture: Cloud-native, API-first, decoupled from mobile systems
AI acceleration: A core enabler — tools such as Cursor, Copilot, and Claude Code used to drive 2–3× productivity.
The first 6 months require high-intensity player-coach leadership, followed by broader engineering leadership as teams consolidate.
What You’ll Own
- Web Platform Rebuild (Months 1–12)
- Design and deliver a new cloud-native web platform
- Lead critical architecture decisions and code reviews
- Champion AI-accelerated engineering practices
- Embed security, compliance, and scalability from day one
- Plan and execute a zero-disruption migration from legacy systems
- Maintain stability of the existing web platform
- Manage technical debt pragmatically
- Engineering Leadership (Months 6–12)
- Consolidate web and mobile engineering teams
- Establish engineering standards, culture, and delivery practices
- Partner closely with product leadership on roadmap and delivery
- Strategic (Ongoing)
- Support investment cases through delivery outcomes
- Define the technical roadmap beyond the initial rebuild
- Build foundations for future team growth
- Naturally evolve toward CTO-level leadership as the organisation scales
