• Leverage AI tooling and LLM-based systems to enhance product features and build enterprise-grade capabilities that meet strict SLA requirements.
• Help build and enhance our observability platform which captures both system stability and user behavior that feeds into our business intelligence and ai platform.
• Manage and improve our CI/CD and AWS EKS infrastructure using Terraform for cloud provisioning and Ansible for on-premise Kubernetes cluster management.
• Champion best practices, test automation, and code quality standards across the engineering organization.

What We're Looking For

• 5+ years of professional software engineering experience, with demonstrated ownership of complex, production systems.
• Strong full-stack proficiency with React, Node.js, and TypeScript; solid understanding of relational databases (PostgreSQL), NoSQL databases, and data platforms (warehouses, lakes, or lakehouses).

• Hands-on experience with observability and monitoring tools such as Datadog, Grafana/Prometheus, or CloudWatch.
• Experience with CI/CD pipelines using tools like GitHub Actions, Jenkins, or Travis CI.
• Strong communication skills and the ability to lead technical initiatives, mentor peers, and influence architectural decisions across teams.
• A critical, systems-level thinker who can evaluate trade-offs, propose multiple solutions, and align stakeholders around the right path forward.

Nice to Have
