WalletConnect is looking for a Senior Backend Engineer to join our Pay team. You will be responsible for building and owning backend services across payment orchestration, merchant APIs, settlement flows, and internal business systems. You will design APIs, build services, own deployments, and ensure systems are correct, observable, and production-grade.
What You'll Do
- Design, build, and maintain backend services across the WalletConnect Pay platform — payment flows, APIs, data pipelines, and internal tooling.
- Make sound architectural decisions for owned services: 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 services end-to-end: implementation, testing, deployment, monitoring, and operational support.
- Contribute infrastructure using AWS and Terraform.
- Build observability into everything shipped: logging, metrics, tracing, and alerting.
- 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.
- Participate in code review culture with AI-assisted development workflows.
- Contribute to engineering standards, documentation, and team processes.
What We're Looking For
- Senior-level backend engineering experience designing, shipping, and operating production services with real users and real consequences.
- Strong API and system design skills, able to make sound architectural decisions in ambiguous problem spaces and reason clearly about trade-offs.
- Production experience with cloud infrastructure (AWS preferred), comfortable with managed services in a cloud-native environment.
- Comfortable owning infrastructure via Terraform or equivalent, deploying and managing what you build.
- Ability to translate business requirements from non-engineering stakeholders into correct, maintainable implementations.
- Strong written and verbal communication, writing clear technical documents and reasoning about trade-offs with non-engineers.
- Effective use of AI tools in day-to-day engineering, with AI-assisted coding combined with strong human review.
Nice to Have
- Rust experience or strong systems-language background with willingness to ramp quickly (AI-assisted).
- Experience with payment systems or financial infrastructure, transaction lifecycles, settlement, reconciliation, fees, FX.
- Experience building merchant-facing or developer-facing APIs and tooling.
- Exposure to data transformation, reporting pipelines, or internal business systems.
- Crypto/Web3 familiarity: understanding of wallets, tokens, chains, stablecoins, or on-chain settlement patterns.

- Rust
- TypeScript
