• Delivering the whole lifecycle of deployable features: design, code, testing, configuration, documentation, deployment, and support
• Contributing to operational guidelines, system reliability practices, and post-mortem analysis for production incidents
• Teaching and enforcing development methodologies while proactively identifying improvement opportunities in codebase, tooling, and processes
• Collaborating with QA and Platform Engineering teams to test code and keep our integrated testing environments unblocked
• Providing technical guidance to cross-functional teams on integration approaches and system constraints to deliver features and evolve our architecture

Qualifications:

• 5-7 years of software engineering experience with ~2 years of senior-level responsibilities such as taking ownership of designs or projects and working to coordinate work across teams
• Operational knowledge of one or more server-side object-oriented programming languages (Java, Kotlin, Scala, or other JVM languages preferred; Python, Go, Node/TypeScript also considered)
• Able to talk comfortably about microservices architecture, distributed system design, streaming data, messaging technologies, and database design patterns
