Nice to have

• Experience with Python for building services and APIs.
• Experience building observability, monitoring, or analytics platforms.
• Familiarity with cybersecurity concepts or security tools.
• Experience with data visualization libraries (Recharts, D3.js, Plotly).
• Experience with message queues (Redis, RabbitMQ, BullMQ, Kafka) for asynchronous processing.
• Experience with AWS or Azure cloud infrastructure.
• Background working on enterprise SaaS or B2B products.
• Experience building analytics dashboards with drill-down capabilities.
• Experience building applications that provide visibility into AI systems.

Why join us
