Java Technical Lead - Modernisation & Cloud Engineering
📍 Wembley, London (5 days on-site)
💰 Up to £85,000 per annum
The Opportunity
We're partnering with a well-established, multinational organisation embarking on a major transformation-rebuilding its digital engine from the ground up.
They are looking for a Modernisation Engineering Lead who breathes engineering excellence.
If you're a 10+ year Java/Spring Boot expert who is tired of bloated, unmaintainable systems and wants the authority to "fix it properly", this is your opportunity to make a lasting impact.
You will work directly with the Head of Architecture, turning high-level designs into verifiably stable, scalable, cloud-native solutions-with real ownership, influence, and autonomy.
What You'll Own
⚙️ Engineering Sovereignty
Define and enforce Java and Node.js engineering standards across the platform
Set the benchmark for:
Robust exception handling
Binary stream processing
Structured logging (Application Insights)
Security-first development
Drive a culture of clean, maintainable, production-grade code
☁️ Cloud-Native Excellence
Ensure all systems are built for Azure Container Apps from day one
Own best practice implementation across:
Stateless architecture
Health check endpoints
Secure secret management (Azure Key Vault)
Containerisation standards and deployment readiness
🔗 The Integration Engine
Lead API and integration strategy, including:
RESTful API design
OAuth2 authentication flows (including FusionAuth)
Event-driven systems via Azure Service Bus
Transactional email logic via SendGrid (DMARC compliant)
🧠 Mentorship & Code Leadership
Act as a hands-on technical mentor, not just a lead
Run structured code reviews to eliminate technical debt before production
Elevate team capability and enforce engineering discipline at every level
🚀 Architecture to Reality
Work side-by-side with the Principal / Head of Architecture
Translate high-level designs into deliverable implementation plans
Ensure developers understand not just what to build-but why
✅ Quality & DevOps Mindset
Embed a non-negotiable automated testing culture:
Unit
Integration
Contract testing
Operate with a strong understanding of:
CI/CD pipelines
Docker
GitHub Actions (YAML workflows)
Build software that is deployment-aware and production-ready from day one
What We're Looking For
✅ Experience
10+ years Java development, with deep expertise in:
Spring Boot
Microservices architecture
Proven production ownership of scalable systems
☁️ Cloud & Integration
Hands-on experience with Azure-native services, including:
Azure Key Vault
Azure Service Bus
Azure Storage APIs
Strong experience building event-driven, distributed systems
⚙️ DevOps Mindset
Comfortable working with:
Docker
CI/CD pipelines
GitHub Actions
Able to write code with full awareness of how it is built, tested, and deployed
🧪 Engineering Discipline
Strong advocate of automated testing and quality-first development
Passion for eliminating technical debt and improving legacy systems
Why This Role?
Join a business where you will genuinely shape the engineering landscape
Work directly with senior architecture on strategic modernisation
Take ownership of how software is built, delivered, and maintained
Be empowered to fix long-standing technical problems properly-not patch them
