About 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, 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!

We’re looking for a Lead Site Reliability Engineer to own the reliability, performance, and automation of our cloud-based, real-time platform. This role will focus on keeping our platform running smoothly 24/7, minimizing downtime, improving observability, incident response, and self-healing automation.

• Lead the adoption of infrastructure as code (Terraform) to fully automate infrastructure management.

• Build and refine a world-class monitoring, alerting, and logging system using Prometheus, Grafana, OpenTelemetry, and Datadog.

• Lead incident response and on-call operations, reducing mean time to detection (MTTD) and mean time to resolution (MTTR).

• Conduct blameless postmortems and continuously improve system resilience.

• Partner with Security & Compliance teams to ensure infrastructure meets HIPAA and SOC 2 standards.

• Lead disaster recovery and business continuity planning to ensure critical healthcare services are always available.

• Strong background in monitoring, logging, and observability with Prometheus, OpenTelemetry, or similar tools.

• Hands-on experience with incident management, postmortems, and building resilient systems.

• Deep knowledge of CI/CD automation, GitOps, and infrastructure as code (Terraform, etc.).

• A mature leadership approach, with the ability to drive technical strategy while growing and mentoring a high-performance SRE team.

• Strong understanding of network security, access management, and compliance frameworks (HIPAA, SOC 2).

Bonus Points If You Have:

• Experience with healthcare IT, including EHR data, FHIR, and HL7 interoperability.
