# Cleared Software Engineer, Integrations

- **Company:** Lumbra Inc.
- **Location:** Arlington, TX, United States
- **Contract:** Permanent contract
- **Skills:** Application Programming Interfaces (APIs), Information Engineering, Extract Transform Load (ETL), Software Debugging, Graph Database, Python (Programming Language), Open Source Intelligence, Package Management Systems, Systems Integration, Workflow Management Systems, HybridCloud, Rate Limiting, Kubernetes, Rancher
- **Published:** July 21, 2026
- **Apply:** https://www.clearancejobs.com/jobs/9044527/cleared-software-engineer-integrations

## About the Role

* 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

## 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.
