Job summary

Horizon3 is hiring for a senior Platform Integration role to advance a GraphQL‑federated API platform and a shared Integration Router. You will connect NodeZero to tools across security and IT ecosystems, and help define platform standards.

This senior individual contributor role requires balancing architectural judgment with hands‑on delivery, mentoring engineers, and owning production systems across multiple environments.

Qualifications

• Bachelor's degree in Computer Science, Computer Engineering, or related field.
• 7+ years of professional software engineering experience using modern object‑oriented or functional languages (Python, Go, TypeScript, Java, Scala, C++, etc.).
• Experience building production applications on cloud platforms (AWS, Azure, GCP) using Docker and Kubernetes.

Responsibilities

• Design and implement backend APIs in GraphQL — including federated subgraph development, schema evolution, and multi‑account query scoping for MSSP and multi‑subsidiary customers.
• Build and extend the Integration Router: connector libraries, workflow configuration, secrets management, vendor adapters, and Kafka‑triggered dispatch services.
• Own production reliability for API and integration services: monitoring, alerting, deployment, vendor API drift, rate limits, retries, and safe failure handling.
• Contribute to the MCP platform and OAuth proxy layer, including tool authentication and agentic workflow support.
• Contribute production code that sets the standard for design quality, code quality, and operational rigor.
• Collaborate with frontend engineers, product managers, and security‑domain teams (particularly the Pentest Data Platform) to deliver integrated customer experiences.
• Mentor junior and mid‑level engineers on the team as it scales.
