Job description
- Build and maintain integration tools in Python that connect agents to external data sources, APIs, and analyst workflows. You need strong Python skills and experience writing reliable, well-tested connectors that handle authentication, rate limiting, and error recovery.
- Extend and create MCP servers with new tool registrations, resource types, and transport mechanisms.
- Develop connectors for collaboration platforms and communication channels, enabling agents to interact with analysts in the tools they already use.
- Maintain deployment parity by ensuring all new features, environment variables, and configurations work across commercial cloud, on-prem cloud, and air-gapped environments. You'll work closely with the infrastructure team to keep all tracks aligned.
- Write thorough tests for all integration code, covering error cases, network failures, and edge conditions in disconnected environments. You'll follow a contract-driven testing approach with clear coverage expectations.
- Support onsite deployments by troubleshooting issues in air-gapped Kubernetes clusters where standard debugging tools aren't available. Resourcefulness and self-sufficiency are essential.
- Care deeply about integration performance and reliability: connection pooling, retry efficiency, parsing throughput, and end-to-end latency from data source to agent. In constrained environments, every wasted cycle and unnecessary round-trip compounds.
- Ensure all integration code meets security standards for classified environments: no hardcoded secrets, proper credential handling, and audit-ready practices throughout.
Requirements
- Experience writing, deploying, and operating software in air-gapped or SCIF environments, including disconnected package management and offline container registries
- Prior work with intelligence community tools, data formats, or workflows (STIX/TAXII, OSINT platforms, imagery analysis pipelines)
- Familiarity with workflow orchestration (Temporal or similar) for durable, multi-step integration tasks
- Experience with Helm chart authoring and Kubernetes manifest management across multiple deployment targets
- Background in data engineering: ETL pipelines, schema normalization, or multi-source data fusion
- Experience with graph databases for knowledge extraction and entity resolution
- Familiarity with Rancher, ArgoCD, and Harbor in air-gapped or restricted environments
- Prior work on FedRAMP, IL4/IL5, or similar compliance-bounded software delivery
