Nice-to-have qualifications * MDM experience (Jamf, Intune, Kandji) at a non-trivial scale. * Authentication stack: OAuth/OIDC, SAML, mTLS, SCIM, and the operational reality of SSO rollouts at enterprise customers. Clearance and Eligibility Because our product integrates with Computer-Aided Dispatch (CAD) and other systems that may handle Criminal Justice Information (CJI), this role requires: Eligibility to pass a fingerprint-based national background check under the FBI CJIS Security Policy. Completion of CJIS Security Awareness Training and approval by the relevant CJIS Systems Agency (CSA) prior to accessing production CJI environments. Status as a U.S. person (U.S. citizen or lawful permanent resident). Willingness to comply with agency-specific personnel security requirements, which can include drug screening, additional background checks, and ongoing recertification. ## Description HEN builds the connected systems fire departments use to run incidents from intelligent hardware at the hydrant, FDC, and pump panel through to the command tablet on scene and the chief's strategic dashboard. STAR-IQ is our incident command platform: an iOS/web app that gives Incident Commanders and Battalion Chiefs live unit assignments, comms channels, org structure, building preplans, and progress tracking during active incidents. It runs alongside CAD, building/preplan databases, mapping services, and our broader ecosystem (CRUX, TITAN, FLUID-IQ, the ARES agentic co-pilot).You will help define HEN's interoperability architecture across CAD, GIS, identity, telemetry, and incident-command systems., * Build and mentor the core platform interoperability team * Define the long-term scalable architecture working with the core development team, and manage the entire production integration strategy with Fire Departments (FD), with a critical focus on ensuring a zero-downtime rollout of the STAR-IQ system. * CAD integration. Work with Fire Departments (FD) and Computer-Aided Dispatch(CAD) vendors to design and maintain the integration service that ingests incident data from CAD systems, transforms the CAD data to a unified schema, and exposes it to the STAR-IQ backend system. * Building and preplan data. Build integrations and ingest FD preplan and building data to the STAR-IQ backend, normalizing wildly different source schemas into a reliable application format. * Mapping and GIS. Integrating Mapbox, ESRI, and department-custom GIS layers behind the Map and Dashboard surfaces - hydrants, FD assets, weather, exposures, district boundaries. * Identity and device management. Wiring up SSO, AuthN/AuthZ (GCP), and MDM flows so a department can provision users and iPads at scale without HEN being in the loop for every change. * Audit and incident data. Making sure every integration writes through the append-only audit log and respects the data model that separates production, training, and simulated data. * Field reliability and partner enablement. Writing the integration docs, sample payloads, and conformance tests that a CAD vendor or FD IT team can actually use. Running joint technical integration sessions with departments during rollout. * Compliance-aware design. Building integrations that respect CJIS Security * Policy, agency-specific data handling rules, and the separation between production CJI and our training/simulated environments. ## Related Videos - [Keeping applications secure by evolving OAuth 2.0 and OpenID Connect](https://www.wearedevelopers.com/videos/100152-keeping-applications-secure-by-evolving-oauth-2-0-and-openid-connect) - [Remote Driving on Plant Grounds with State-of-the-Art Cloud Technologies](https://www.wearedevelopers.com/videos/251-remote-driving-on-plant-grounds-with-state-of-the-art-cloud-technologies) - [Developing the Backend with Stefan Lingler, CTO at Shpock](https://www.wearedevelopers.com/videos/100360-developing-the-backend-with-stefan-lingler-cto-at-shpock) - [Get started with securing your cloud-native Java microservices applications](https://www.wearedevelopers.com/videos/123-get-started-with-securing-your-cloud-native-java-microservices-applications) - [Delay the AI Overlords: How OAuth and OpenFGA Can Keep Your AI Agents from Going Rogue](https://www.wearedevelopers.com/videos/1637-delay-the-ai-overlords-how-oauth-and-openfga-can-keep-your-ai-agents-from-going-rogue) - [Delegating the chores of authenticating users to Keycloak](https://www.wearedevelopers.com/videos/1558-delegating-the-chores-of-authenticating-users-to-keycloak) ## Related Articles - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Everything a Developer Needs to Know About MCP with Neo4j](https://www.wearedevelopers.com/magazine/604-everything-a-developer-needs-to-know-about-mcp-with-neo4j) - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [The Most Popular IT Jobs on the Market](https://www.wearedevelopers.com/magazine/376-the-most-popular-it-jobs-on-the-market) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated)
