The Role

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

What you bring to the team

• 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.
