- Terraform and / or AWS CDK.
- TOGAF certification is a plus.
- Solid experience designing Spring Boot microservices and REST APIs as modernisation targets
- Strangler fig, domain-driven decomposition, anti-corruption layers and incremental cutover
- Senior-level track record of owning complex modernisation or migration end to end, under ambiguity and incomplete documentation.
- Demonstrated ability to reverse-engineer unfamiliar, poorly-documented systems and recover how they actually behave — the willingness to go and find the answer is the core trait we are hiring for.
- Understanding of how to retire legacy systems safely: data archival / retention, parallel-run exit criteria, dependency sunset sequencing and cost-retirement cases.
- Comfortable using LLM / agentic tooling — including the internal accelerators we provide — to speed up legacy comprehension, translation and parity testing, and ideas on improving them.
- Hands-on with core services (EKS, Aurora / RDS, API Gateway, SQS / SNS, Lambda, IAM, VPC). AWS Solutions Architect (Associate or Professional) preferred
- Relational migration experience (e.g. Oracle → PostgreSQL / Aurora); familiarity with AWS SCT and DMS
- Practical experience proving equivalence between legacy and modernised systems (characterization testing, shadow running, reconciliation).
- GitHub Actions, Docker, and Kubernetes / EKS
- IAM, VPC design and secrets management (e.g. AWS Secrets Manager); awareness of supply-chain and cloud-posture tooling (GHAS, Wiz or equivalent).
- Design-level understanding of Angular as the target UI, enough to scope APEX UI rebuilds — hands-on Angular development is not required
- Bachelor’s or Master’s degree in Computer Science, Software Engineering or a related field — or equivalent practical experience.
- AWS Certified Solutions Architect (Associate or Professional).
