Staff Software Engineer

Staff Software Engineer role at Kontakt.io, responsible for data ingress and egress pipelines, device integrations, and architectural leadership. The team builds event-driven systems using Kafka, gRPC, and observability tools.

• Data ingress & device integration: Own the pipeline that brings external device data into the 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 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.
