• Own end-to-end delivery of features and services, from technical design and implementation through deployment, monitoring, and iteration, ensuring high availability and operational excellence.
• Diagnose and resolve complex production issues, perform root cause analysis, and drive long-term improvements in reliability, observability, and resilience across services and dependencies.
• Collaborate with cross-functional partners, contributing technical expertise to product discovery, backlog prioritization, and data-driven decision making while ensuring solutions are reusable and fungible across multiple domains.
• Safely integrate and operate AI/ML-enabled solutions that improve outcomes, including familiarity with AI-driven systems, tools, or workflows and applying AI/ML concepts to real world products.

• Bachelor's degree in Computer Science or a related technical field; or Equivalent related professional experience.
• 2+ years of relevant professional experience.
• Hands-on experience designing and implementing system components, including APIs, low-level design, and data modeling for single or multi-service ownership.
• Proficiency in at least one modern programming language and associated frameworks, with solid understanding of data structures, algorithms, debugging, and unit/integration testing.
• Experience contributing to the operational lifecycle of services (monitoring, alerting, deployment pipelines, and incident handling) within a team setting.

Preferred Qualifications:

• Full-stack engineer with proficiency in JavaScript, TypeScript, React, Java/Kotlin, and GraphQL.
• Experience maintaining and operating at least four software projects or products in production environments, including bug fixing, troubleshooting, monitoring, and operational support.
• Experience selecting technologies to solve business problems and understanding trade‑offs between languages and platforms.
• Experience creating APIs consumed across teams or business units.
• Solid understanding of how projects and teams interact with other teams and align to business needs.
• Experience testing, monitoring, debugging, and fixing issues within defined SLAs.
