What you need
- 7+ years building production backend systems at scale
- Deep expertise in Java — Spring Framework, Gradle, and JVM performance tuning
- Production experience with event-driven architectures — AWS Kinesis, Kafka, or equivalent
- Strong system design fundamentals: domain decomposition, modularity, schema evolution
- AWS production experience across EKS/ECS, S3, SQS/SNS, and IAM
- A demonstrated track record of driving architecture decisions and authoring design docs without formal authority
Nice to have
- Working proficiency in Python for tooling, automation, or data workflows
- Experience with MongoDB at scale — indexing, aggregation pipelines, sharding
- Hands-on experience with AI-assisted development: LLM coding agents, prompt engineering, or MCP tooling
- Experience evolving large monoliths toward modular or service-oriented architectures
- Familiarity with the hospitality domain — PMS/CRS systems, rate management, or demand forecasting
Worth weighing
- No salary listed
- Role involves significant architectural authority and influence without formal management responsibilities
