• Familiarity with CI/CD pipelines and cloud‑based testing environments
• Excellent problem‑solving skills and attention to detail
• Strong communication and collaboration skills

Nice‑to‑Have Skills

• Familiarity with testing LLM‑powered applications and agentic systems
• Experience with infrastructure‑as‑code (CDK, Terraform, CloudFormation)
• Familiarity with software design patterns and refactoring techniques
• Background in distributed systems or cloud architecture
• Knowledge of observability patterns (structured logging, distributed tracing, metrics instrumentation)
• Familiarity with monitoring and alerting tools (Grafana, DataDog, CloudWatch)
• Experience with BDD and contract testing (Pact)
• Familiarity with AWS services (S3, DynamoDB, OpenSearch)
