SAP GTS (German Speaker)

We are seeking a highly experienced, hands-on Technology Lead to drive a strategic application modernization programme, transforming legacy Java applications into scalable, secure and cloud-native solutions on AWS.

The role combines architecture leadership, software engineering, database administration, Dev Ops and customer-facing delivery ownership.

The successful candidate will define the target architecture, lead engineering teams, guide database and platform modernisation, establish delivery standards, and act as a trusted technical advisor to customer stakeholders throughout discovery, design, build, migration and production transition.

Core mandate: Modernise a Java-based enterprise application using AWS serverless and container services, supported by robust data architecture, automated delivery and strong customer communication.

Key Responsibilities

• Lead end-to-end modernization of enterprise Java applications into AWS cloud-native, microservices and event-driven architectures.
• Define the modernization roadmap, target architecture, transition states, technical standards and engineering guardrails.
• Drive API-first design, domain-driven design, serverless adoption and decomposition of monolithic applications.
• Own technical decisions, architecture reviews, non-functional requirements and resolution of cross-workstream dependencies.
• Ensure solutions meet scalability, availability, security, maintainability and operational readiness objectives.
• Design and implement containerised workloads using Amazon ECS, AWS Fargate, Docker, Application Load Balancer and Amazon ECR.
• Design serverless and event-driven solutions using AWS Lambda, Amazon API Gateway, Event Bridge, SQS, SNS and AWS Step Functions.
• Apply AWS services including Amazon S3, Cloud Watch, Cloud Trail, IAM, Secrets Manager, Systems Manager, AWS Config, VPC, Route 53 and Private Link.
• Define resilient deployment patterns, observability, security controls, backup, recovery and production support models.
• Provide hands‑on support for solution prototypes, complex defects, performance bottlenecks and production readiness.
• Software Engineering
• Provide hands‑on technical leadership across Java 11/17+, Spring Boot, Spring Cloud, REST APIs, Python and Type Script.
• Define coding standards, reusable components, design patterns, secure development practices and code review processes.
• Guide teams on microservices, distributed systems, asynchronous integration and fault‑tolerant application design.
• Contribute directly to critical code, proof‑of‑concepts, technical spikes and root‑cause analysis when required.
• Mentor developers and ensure consistent engineering quality across distributed teams.
• Amazon Dynamo DB
• Design Dynamo DB data models aligned to application access patterns, scale, latency and consistency requirements.
• Apply single-table and multi-table design approaches, including partition keys, sort keys, GSIs and LSIs.
• Configure and optimise capacity models, auto scaling, TTL, point-in-time recovery, Streams and Global Tables where appropriate.
• Diagnose hot partitions, throttling, inefficient access patterns and cost or performance issues.
• Plan and execute data migration, validation and operational support for high-volume serverless workloads.
• Provide hands‑on architecture, administration and operational support for Aurora Postgre SQL and Postgre SQL environments.
• Design schemas, data models, indexing strategies, partitioning and database standards for transactional workloads.
• Perform SQL tuning, execution plan analysis, query optimisation, workload troubleshooting and performance remediation.
• Design high availability, replicas, failover, backup, restore, patching, maintenance and disaster recovery arrangements.
• Lead database migration from Oracle, My SQL, Postgre SQL or other legacy platforms using appropriate AWS migration services and tools.
• Implement database security, encryption, access controls, secrets management, auditing, retention and archival policies.
• Broader Database Capabilities
• Strong knowledge of relational and No SQL data modelling, transaction management and consistency patterns.
• Experience supporting mission-critical, high-volume systems with demanding availability and performance requirements.
• Hands‑on monitoring using Amazon Cloud Watch, Performance Insights and database-native diagnostic tools.
• Ability to assess when to use Aurora Postgre SQL, Dynamo DB or other AWS data services based on workload characteristics.
• Design and govern CI/CD pipelines using Jenkins, Git, Git Hub Actions, AWS Code Pipeline and AWS Code Build.
• Automate infrastructure and application deployment using Terraform and/or AWS Cloud Formation.
• Embed automated testing, code quality checks, vulnerability scanning, policy controls and release approvals into delivery pipelines.
• Establish container image management, environment promotion, rollback, configuration and secrets‑management standards.
• Define monitoring, logging, tracing, alerting, SLOs and operational dashboards for cloud-native workloads.
• Drive Dev Sec Ops practices and continuous improvement across engineering and operations teams.
• Customer Engagement & Delivery Leadership
• Act as the primary technical point of contact and trusted advisor for customer architects, engineering leaders and programme stakeholders.
• Lead discovery sessions, architecture workshops, design reviews, technical governance forums and steering discussions.
• Translate business and operational requirements into clear, scalable and pragmatic technical solutions.
• Communicate architecture decisions, delivery progress, dependencies, risks and mitigation actions to technical and executive audiences.
• Provide clear written documentation, presentations and recommendations, adapting the level of detail for each stakeholder group.
• Lead, mentor and coordinate architects, developers, Dev Ops engineers, cloud engineers and database specialists across workstreams.
• Support estimation, planning, resource shaping, technical proposals and delivery assurance.
