About this role: As a Senior Software Engineer on the Ecosystem Services Team, you’ll build and own back-end systems and the integrations that keep our services running, help maintain and evolve the cloud infrastructure the application runs on, and play an active role in keeping the service reliable and healthy in production. You'll do this while collaborating closely with frontend engineers, product managers, CloudEng, and UX and design partners to deliver reliable features.
Responsibilities
- Lead backend development, building and maintaining server-side logic
- Take real ownership of the services you work on: deploy them, operate them, and keep them healthy in production rather than handing them off
- Work closely with our CloudEng Team to maintain and improve production environments, including monitoring and alerting with tools such as OpenTelemetry, Sentry, Prometheus, and Grafana
- Participate in an on-call / off-hours support rotation, triaging and resolving production issues, partnering with CloudEng and support teams to investigate incidents, address bug reports, and keep the application running reliably
- Periodically rotate into a support role, handling releases, dependency updates, and incoming work requests from customer support and other stakeholders
- Thoughtfully apply AI-assisted development tools to move faster and raise quality, while maintaining good judgment about where they fit and where they don't
- Partner with and support stakeholders (e.g. front-end, platform), ensuring backend systems, APIs, and data contracts meet their needs
- Partner with frontend and cross-functional teams to align on project goals, contribute to API design, and ensure backend systems, APIs, and data contracts meet their needs
- Participate in code reviews to maintain high standards of code quality and system reliability
- Participate in security and privacy reviews, ensuring all data protection measures meet compliance standards
