About Opaque

We’re building a secure, privacy-preserving data and AI platform called the Confidential AI platform. Our mission is to build the trust layer for the agentic economy, enabling organizations to build agents that operate on sensitive data while maintaining the highest levels of security, compliance, and trust.

About the Role

We’re looking for a Senior Software Engineer, Infrastructure who takes ownership, loves solving hard problems, and is driven by curiosity. You’ll design, build, and scale the systems that power Opaque’s Confidential AI platform, from cloud infrastructure and developer tooling to observability and CI/CD.

This role is ideal for an engineer who thrives in fast-moving environments, learns continuously, and communicates proactively. You’ll work closely with product and platform teams to ensure our systems are reliable, secure, and delightful to develop on.

Responsibilities
  • Design, implement, and maintain scalable, secure, and compliant cloud infrastructure using Infrastructure as Code.
  • Build and evolve CI/CD pipelines that improve developer velocity and confidence, balancing speed with safety.
  • Operate and improve Kubernetes-based systems, bridging application and infrastructure to ensure reliability at scale.
  • Participate in on-call rotations, incident response, and postmortems, driving improvements in availability and recovery.
  • Lead observability efforts — defining metrics, building dashboards, and making system health visible and actionable.
  • Drive cost awareness and optimization across environments.
  • Build internal tools and automation that make developers more productive and happy.
  • Collaborate across teams, proactively surfacing issues and opportunities before they become blockers.
You May Be a Good Fit If You
  • Have 5-7+ years of industry experience building and operating production infrastructure.
  • Have led complex, cross-functional projects or acted as a technical lead.
  • Are known for taking ownership, driving projects end to end with a bias for action.
  • Are curious and self-directed, eager to dive into unfamiliar systems or learn new technologies.
  • Communicate clearly, precisely, and proactively, aligning technical direction with stakeholder needs
  • Care deeply about reliability, scalability, and developer experience.
  • Are fluent in at least one language such as Python, Go, Rust, or Java
  • Have deep knowledge of Kubernetes, Azure, GCP, or AWS, and Infrastructure as Code (Terraform, Cloudformation, Pulumi, etc.).
  • Have experience with security or compliance frameworks (SOC 2, ISO 27001, or similar).
Strong candidates may have
  • Experience in early-stage startups or hyper-growth environments.
  • A background in security, privacy, or confidential computing.
  • Contributions to open source or community-driven infrastructure projects.

The story of Opaque Systems begins not in a corporate boardroom, but within the innovative halls of the UC Berkeley RISELab—the same renowned research laboratory that gave birth to transformative technologies like Apache Spark and Databricks. It was here that a team of brilliant researchers, including Ion Stoica and Raluca Ada Popa, identified a critical paradox in the modern data landscape: while organizations possessed vast troves of valuable data, the most sensitive and impactful portions remained locked away, inaccessible for analytics and AI due to strict privacy and regulatory constraints.

Driven by a mission to solve this 'data utility vs. data privacy' dilemma, the team developed and open-sourced the MC2 platform, a breakthrough in secure multi-party computation. Recognizing the immense commercial potential of this technology, they founded Opaque Systems in 2019. Their vision was to create a platform that would allow enterprises to perform collaborative analytics and machine learning directly on encrypted data, without ever exposing the underlying information—even to the cloud providers hosting it.

Today, Opaque Systems has evolved into a leading Confidential AI platform. By leveraging advanced hardware-enforced security known as 'enclaves,' the company empowers organizations to unlock their most sensitive data for the next generation of AI and Large Language Models (LLMs). With the appointment of Aaron Fulkerson as CEO in 2023 and significant Series A funding, Opaque continues to bridge the gap between data privacy and AI innovation, enabling a future where data can be both shared and secure.
