Experience working with cloud platforms such as AWS or equivalent providers.
Nice to Have:
Experience with containerisation and orchestration tools such as Docker and Kubernetes.
Familiarity with RPC frameworks such as gRPC.
Exposure to native mobile development (Swift or Kotlin), or an interest in contributing to mobile codebases over time.
Ability to use AI-assisted development tools to improve productivity, code quality, and system reliability.
What We Offer:
Competitive salary and employee benefits
Opportunity to work on core platform systems with real-world impact
Close collaboration with experienced engineers and product leaders
