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.
