• Build observability into services through metrics, dashboards, monitoring, and alerting.
• Work with internal team sand partners to turn requirements into practical platform capabilities.
• Contribute to the evolution of the platform's backend architecture and service integration.

Required Skills and Experience

• Strong coding ability in Python and comfortable in scripting (e.g. bash).
• Proven experience designing, building, and operating backend services or internal platforms in production environments.
• Strong understanding of API design, service-to-service integration, and backend architecture.
• Experience working in cloud environments, ideally AWS.
• Experience with containers and related tooling, for example Docker.
• Familiarity with CI/CD practices and modern engineering workflows.
• Good communication skills and the ability to work effectively across security and engineering teams.

“Nice to Have” Skills and Experience

• Experience with large-scale analysis pipelines, data processing, or workflow orchestration.
• Familiarity with observability tooling, operational metrics, and service health dashboards.
• Experience integrating AI/ML capabilities, including large language models, into production software or developer tooling.
• Familiarity with evaluating, monitoring, and improving AI-assisted workflows, particularly for security analysis, code analysis, or engineering productivity.
