The digital pathology market is experiencing explosive growth as advances in AI enable unprecedented insights into diseases like cancer. Pathology is central to medicine, and the shift to AI-powered solutions is not just modernizing workflows-it's transforming how diseases are diagnosed, treated, and understood. Predictions for the future of pathology show a tidal wave of adoption, with experts describing the field as "poised for the next major breakthrough" in healthcare innovation.

Backed by over $100 million in funding from leading healthcare and technology investors, Proscia is at the forefront of this revolution. Joining Proscia means being part of a company at the cutting edge of healthcare innovation, where the possibilities are limitless. With the convergence of AI, precision medicine, and digital pathology, we're not just changing pathology-we're redefining what's possible in medicine.

About This Position

As a Reliability Engineer reporting to the VP, Technical Operations, you will own the reliability, performance, and operational excellence of Proscia's installations at customer sites. Our platform powers high-resolution digital pathology and AI-assisted workflows/diagnostics in clinical and research environments, often running on customer-managed infrastructure. You'll ensure these deployments are stable, performant, secure, and continuously improving. AI tools are a natural part of how you diagnose, automate, and operate.

This is a hands-on role with a focus on container-based deployments, systems performance, and real-world operational problem-solving in environments where rigor matters.

What You'll Do

Working at a startup like Proscia means wearing many hats, but when you come to work you can expect to focus on the following:

* Deploy, configure, and support Proscia's container based application stack in on-premise customer environments.

* Own system reliability across customer installations, including uptime, performance, backup/recovery, and upgrade workflows.

* Diagnose and resolve production incidents-deep root cause analysis across application, container, host, storage, and networking layers, using AI alongside traditional debugging to correlate signals and cut through noise.

* Optimize performance for large image datasets and AI workloads running on customer-managed compute infrastructure.

* Improve installation automation, configuration management, and repeatability across diverse environments integrating agentic workflows in your day-to-day to keep pace with demands from Engineering.

* Develop and refine monitoring, logging, and alerting patterns appropriate for customer-hosted deployments.

* Collaborate closely with Engineering, Customer Success, and Support to translate field learnings into product and operational improvements.

* Create operational playbooks-written with the clarity and structure that makes them useful to teammates, customers, and the AI-augmented workflows the team relies on.

* Contribute to Proscia's technical presence-whether through internal demos, engineering blog posts, or operational knowledge sharing that raises the bar for how the team works.

About You

You think in systems-you reason about how applications, infrastructure, and customer environments interact, not just the layer you're working in. AI tools are part of how you operate: troubleshooting, writing automation, navigating the complexity of diverse on-premise environments.

* Deep hands-on experience deploying and operating containerized applications using container orchestration in production environments.

* Strong Linux systems expertise (process management, networking, storage, security hardening, performance tuning)

* Expert troubleshooting skills in distributed systems across application, container, and infrastructure layers.

* Experience with enterprise networking-you can troubleshoot and recommend corrections in customer infrastructure. Comfortable operating software in customer-managed and on-premise environments.

* Experience supporting data-intensive systems, ideally involving large image files or compute-heavy workloads.

* Working knowledge of observability practices (logs, metrics, tracing) and pragmatic monitoring approaches in non-cloud-native environments.

* Comfort working directly with customers or customer-facing teams to resolve high-impact issues.

* You already use AI tools in your operational work, in troubleshooting, writing automation, analyzing logs, or however it fits your practice.

* A mindset aligned with Proscia's values: ownership, speed, simplification, and a willingness to challenge the status quo.

* Experience building with or…
