Design, build, and maintain backend services across the WalletConnect Pay platform — payment flows, APIs, data pipelines, and internal tooling.
Make sound architectural decisions for the services you own: API design, data modelling, error handling, and system boundaries.
Write technical design documents before major implementation work and participate in architectural reviews.
Ship production-quality code with strong testing, clear documentation, and attention to edge cases.
Own your services end-to-end: implementation, testing, deployment, monitoring, and operational support.
Contribute infrastructure using AWS and Terraform. We don’t have a dedicated infra function, so engineers own their infra.
Build observability into everything you ship — logging, metrics, tracing, and alerting that meet the reliability bar of a production payment system.
Respond to and learn from production incidents, driving improvements to system resilience.
Collaborate with cross-functional stakeholders including Product, Design, Ops, Finance, Legal, and BD to turn requirements into clean implementations.
Participate in code review culture with AI-assisted development workflows, including automated agent reviews on PRs.
Contribute to engineering standards, documentation, and team processes that help the Pay team scale.
