Cleared Software Engineer, Integrations
LUMBRA
About the Role Lumbra is building Nebula, an agentic harness operating in environments where analysts need to pull intelligence from diverse, often restricted data streams, and where the harness itself must deploy into on-prem cloud and fully air-gapped environments with limited or no internet connectivity. We're looking for a cleared software engineer to own the integration layer: building connectors to external systems, extending our agent tool framework, and ensuring Nebula works reliably in disconnected classified environments. This role requires an active U.S. security clearance (TS/SCI). What You'll Own 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. Preferred Qualifications 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. Benefits Comprehensive medical, dental, and vision plans Premiums 100% covered by Lumbra for all employees Exceptionally low premiums for spouses and dependents Basic life insurance and disability 100% covered for all employees by Lumbra Option to purchase additional life insurance available Take the time off that you need, when you need it' paid time off, not accrual based Generous company holiday calendar including a holiday shutdown in December Supportive leave of absence program including time off for military service, medical events, and parental leave Full 401(k) retirement plan for all full-time eligible employees Company-funded commuter benefits Free access to on-site gym at office #J-18808-Ljbffr LUMBRA
