About the role
What you’ll do
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
What you’ll bring
4+ years of experience in software development with a strong focus on backend technologies
Strong professional experience with Python, TypeScript/Node.js, or Rust building back-end services and confidence leading back-end engineering projects
Proficiency with PostgreSQL and SQL query optimization, including relational schema design and migrations with a query builder such as Knex
Hands-on DevOps experience on Google Cloud Platform (GCP), with Docker-based build and deploy pipelines. You are comfortable deploying, operating, and troubleshooting services in the cloud rather than handing that responsibility to someone else
Hands-on experience with observability and monitoring tooling such as Sentry and Grafana
A pragmatic commitment to shipping quality work. You care about the quality and reliability of what you ship, you make sensible trade-offs under real constraints, and you consistently move work to and into production
Strong engineering judgment. You can navigate ambiguity, weigh trade-offs, and make sound decisions with incomplete information, and you know when to ask for input
A genuine ownership mindset. You are excited to own a service end to end and have a track record of operating what you build in production, including experience with on-call or off-hours production support
Experience mentoring junior engineers and driving technical excellence in code quality, testing, and process improvements
