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.
• 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.
• 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.

• 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)
• Experience in SC-cleared environments

What We Are Looking For

• A hands-on Technical Scrum Master with strong Java and Spring Boot expertise.
• Ability to challenge engineers on code, design, and implementation decisions.
• Strong engineering mindset focused on quality, performance, and scalability.
• Proven ability to lead developers and testers in a high-performing Agile team.
• Passion for DevOps, automation, and continuous improvement.
