About Kontakt.io http://Kontakt.io Every day, intelligent software orchestrates the physical world around us – from matching drivers with riders to optimizing global supply chains. Yet inside hospitals, where every second and every decision can affect a patient's life, operations are still spread across dozens of disconnected systems. At Kontakt.io http://Kontakt.io, we're changing that. By combining proprietary hardware, AI-powered intelligence, and deep integrations with the systems hospitals already rely on, we're creating a real-time understanding of hospital operations that software alone can't deliver. That intelligence powers the execution layer hospitals have been missing – helping care teams make smarter decisions and deliver better patient care. Backed by Goldman Sachs and trusted by leading health systems including HCA Healthcare, Sutter Health, AdventHealth, Trinity Health, Northwell Health, Cleveland Clinic, and the U.S. Department of Veterans Affairs, we're pioneering the next generation of healthcare operations. We've more than doubled our revenue over the past year and are on track to surpass $70M in annual recurring revenue – not because we're following a market, but because we're defining one. If you're excited to solve hard problems, work with a team of builders, and help hospitals deliver better care every day, we'd love to meet you! Kontakt.io http://Kontakt.io is the leading IoT platform for real-time location and telemetry in healthcare and enterprise. Our systems monitor hundreds of thousands of assets and people across hospitals and campuses globally — processing billions of BLE events daily through a Kafka-first, cloud-native architecture. The team is the connective tissue of this platform. We own the full data ingress pipeline — from third-party devices (Cisco, Aruba, and beyond) to our internal Kafka backbone — and we own egress: streaming enriched location and telemetry data out to downstream systems, external APIs, and partner platforms. We are rebuilding this domain the right way: event-driven, observable, documented, and built to scale. We need a technical anchor — someone senior enough to raise the bar, pragmatic enough to ship, and confident enough to drive alignment across engineering and product. What you will work on: Data ingress & device integration Own the pipeline that brings external device data into the Kontakt.io http://Kontakt.io platform. Build and maintain robust integrations with Cisco Spaces, Aruba, and similar third-party infrastructure. High-volume BLE telemetry, Kafka Streams, gRPC — multi-tenant SaaS where both correctness and latency matter. Data egress & external integrations Build and evolve the egress layer that streams enriched location and event data to partner systems and customer-facing APIs — real-time position feeds, alarm forwarding, standards-compliant adapters. You own how the outside world consumes Kontakt.io http://Kontakt.io data. Architecture & technical leadership You will drive the architectural evolution: what to rewrite, what to stabilize, and how to sequence it without breaking production. You establish the engineering standards — documentation, testing with Testcontainers, observability with Prometheus/Grafana — and you hold the team to them. Cross-team ownership Work directly with product stakeholders to translate business requirements into engineering decisions. When scope is unclear, you clarify it. When dependencies block the team, you resolve them. Day-to-day Reponsibilities: - Design, build, and maintain Java/Spring and Kafka Streams-based services processing real-time BLE and IoT telemetry at scale - Own ingress integrations with third-party location platforms — from protocol understanding to production reliability - Build egress pipelines streaming location and event data to downstream systems via REST, gRPC, and WebSocket - Drive architectural decisions and document them — the team currently
