## About the Role

Software Engineering, Cloud Computing, Artificial Intelligence (AI), Internet Security, Artificial Intelligence (AI) Agents, Computer Security, Product Lifecycle, Database Administration, Software Development, Database Design, * Substantive Python experience in production or enterprise environments - we're looking for engineers who have designed, built, and maintained Python systems with real operational accountability, not solely scripting or automation.

 * PostgreSQL experience is required. Candidates without direct PostgreSQL experience will be considered where they can demonstrate equivalent depth with a comparable relational database system.
 * Hands-on AWS infrastructure management experience, including provisioning and operating resources such as EC2 instances, RDS databases, VPCs, and related services.

Preferred Qualifications

 * Experience with FastAPI.
 * Experience with ClickHouse or other columnar/analytical datastores.
 * Experience working in a security vendor environment, with exposure to large volumes of raw telemetry.
 * Understanding of knowledge graphs and graph databases.
 * Comfort using AI-assisted tooling thoughtfully - for example, to accelerate implementation backed by sound planning and detailed design - paired with strong engineering judgment about when and how to apply it.

Nice to Have

 * Experience managing, maintaining, and tuning PostgreSQL databases at scale.
 * Familiarity with building modern CLI/TUI tooling.
 * Familiarity working with Agentic/MCP technologies.

## Description

This is a hands-on, high-autonomy role spanning the full development lifecycle. The primary focus is software development, with additional responsibility for database management and infrastructure as needed to support the team's systems.

Your day-to-day

 * Build and maintain full-stack applications and backend services using Python, TypeScript, React, and Go.
 * Own and manage large SQL databases backing applications and services used by the Threat Intelligence team, including schema design, query optimization, migrations, and operational health.
 * Proactively identify problems before they become incidents: Seek out reliability, performance, and correctness issues. Improve runbooks, dashboards, alert quality, and automation.
 * Collaborate closely with other engineering teams and threat intelligence stakeholders to deliver outcomes that strengthen the team's ability to produce actionable intelligence.
 * Help manage and maintain AWS infrastructure supporting the team's services: VPC configuration, ECS, Aurora/RDS, EC2, Networking, SNS/SQS, CDK
 * Adhere to best practices when it comes to CI/CD, observability, and monitoring: GitHub Actions, CloudWatch/Grafana, Docker
