Senior Reliability Engineer

About Proscia

Pathology is at the center of medicine and is undergoing a profound transformation as the final frontier of digitization in healthcare. We started Proscia to accelerate pathology’s transition from microscope to images and to use AI to change the way we think about cancer. We can’t change medicine alone. That’s why we’re looking for curious thinkers, big dreamers, and problem-solvers—exceptional talent to help us use the power of AI for good and advance humankind.

At Proscia, we push the limits of medicine and technology, solving problems the world has never solved before. Our software is used by thousands of scientists and pathologists who work on the front lines of fighting diseases like cancer. To accelerate our vision, Proscia has raised over $100M in capital from world-class healthcare and technology investors.

About this Position

As a Senior Reliability Engineer, you will be a key part of Proscia’s Technical Operations team, ensuring the security, reliability, and efficiency of our SaaS and Customer-Managed environments. You will own and innovate automation processes, optimize infrastructure, and play a leadership role in DevOps, CI/CD, and cloud security. With a strong focus on AWS security tools and information security best practices, you will ensure our systems remain resilient while meeting the highest security standards.

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:

• Design, build, and enhance Proscia’s Hosted SaaS environment using the latest technologies and Infrastructure as Code (IaC).
• Develop secure and scalable deployment processes that ensure compliance with AWS security best practices, including AWS Security Hub, GuardDuty, IAM, and VPC security controls.
• Automate provisioning, upgrading, and maintenance for both Hosted and Customer-Managed environments to enhance efficiency and security.
• Partner with engineering teams to drive best practices in secure DevOps, CI/CD pipelines, and infrastructure architecture.
• Implement monitoring and alerting solutions that focus on symptom-based detection rather than simple outage notifications.
• Reduce risk by proactively identifying and mitigating reliability and security threats, including vulnerability management and compliance adherence.
• Own TechOps services and participate in an on-call rotation for after-hours emergencies, ensuring minimal downtime and swift incident resolution.
• Drive a security-first culture by mentoring others in cloud security and compliance principles.

We’re looking for people who are smart, respectful, and get stuff done. Proscia is a high-growth company, and we want entrepreneurial doers who thrive in a dynamic environment. The ideal candidate will have:

• 5+ years of experience in Site Reliability Engineering (SRE), DevOps, or Cloud Engineering roles.
• Expertise in AWS security tools and best practices, including AWS Security Hub, GuardDuty, IAM roles & policies, VPC security, and encryption standards.
• Strong experience with IaC tools, such as Terraform or CloudFormation, to automate secure infrastructure deployments.
• Hands-on experience securing Kubernetes, Docker, and containerized environments.
• Deep Linux system knowledge with strong troubleshooting skills.
• Experience designing and managing complex CI/CD pipelines.
• A passion for automation and eliminating manual processes.
• Ability to diagnose and remediate complex security vulnerabilities.
• Experience with security monitoring, incident response, and compliance frameworks such as SOC 2, HIPAA, or ISO 27001.
