Technical Scrum Master (AWS / Java / Spring Boot Microservices)

Location: Hybrid – Solihull (2 days per week) with occasional travel to Croydon

Security Clearance: SC + NPPV3 (required)

About the Role

We are seeking a Technical Scrum Master with strong hands-on expertise in Java and Spring Boot microservices to lead Agile delivery within a cloud-first, engineering-led environment supporting critical national infrastructure transformation.

This is not a traditional Scrum Master role. You will combine Agile leadership with deep technical capability in Java-based microservices, enabling you to actively challenge code, influence engineering decisions, and drive DevOps best practices across AWS platforms.

You will operate as a technical authority within the squad, working closely with the Technical Delivery Manager, Product Owners, Architects, Developers, and Test Engineers to ensure high-quality, secure, and predictable delivery of application and DevOps initiatives.

Key Responsibilities

Agile Delivery Leadership

• Lead Scrum ceremonies and ensure effective sprint planning, execution, and delivery outcomes.

• Drive predictable delivery across Java microservices development and DevOps initiatives.

• Collaborate with the Technical Delivery Manager to manage sprint risks, dependencies, and commitments.

Technical Leadership & Engineering Oversight

• Review and challenge Java and Spring Boot microservices code to ensure adherence to clean code, performance, scalability, and security best practices.

• Provide technical leadership on microservices design, API standards, and service-to-service communication.

• Influence engineering decisions related to Java frameworks, design patterns, and implementation approaches.

• Partner with architects to ensure microservices are aligned with AWS cloud-native principles.

• Drive code quality improvements through reviews, static analysis, and test coverage.

DevOps & Engineering Excellence

• Drive CI/CD pipeline optimisation for Java-based services, including build, test, and deployment automation.

• Promote DevSecOps practices, including secure coding, automated testing, and infrastructure-as-code.

• Ensure effective integration of microservices into deployment pipelines and runtime environments.

• Improve observability across services (logging, monitoring, alerting).

Team & Delivery Management

• Provide day-to-day technical leadership to Java developers and test engineers.

• Hold teams accountable for code quality, microservices standards, and delivery outcomes.

• Support backlog refinement with strong focus on technical enablers and microservices dependencies.

Governance, Metrics & Continuous Improvement

• Track delivery using DORA metrics and engineering KPIs.

• Monitor pipeline performance, defect rates, and service reliability.

• Support production issue resolution with code-level root cause analysis.

Essential Skills & Experience

• Strong hands-on experience in Java and Spring Boot microservices development (mandatory).

• Proven ability to read, review, and challenge Java code in a DevOps environment.

• Experience building and supporting RESTful APIs and microservices architectures.

• 5+ years Scrum Master experience in cloud/DevOps environments.

• Strong AWS experience (EC2, Lambda, S3, IAM, CloudWatch).

• Expertise in CI/CD for Java applications (Jenkins, GitHub Actions, etc.).

• Experience with Docker and container platforms (ECS/EKS).

• Strong understanding of testing strategies for microservices.

• Experience working in regulated environments.

Desirable Qualifications

• Scrum certifications (CSM / PSM)

• SAFe certifications

• AWS certifications

• Experience in SC-cleared environments

What We Are Looking For
