Your role and responsibilities

About the Team

The Secure Compute team builds and operates the foundational infrastructure layer that powers Confluent Cloud. Our mission is to enable the safe execution of code and data processing in multi-tenant environments across AWS, Azure, and GCP at scale. We provide the essential building blocks, including isolation, identity, and networking, that empower both our customers and internal product teams to innovate without compromising security.

As Confluent's product portfolio expands, our team sits at the center of the company's growth. We own a polyglot, container-based runtime that operates across thousands of clusters globally, solving some of the most complex challenges in distributed systems and cloud-native architecture. By balancing world-class security with operational cost-efficiency, we ensure that Confluent Cloud remains the trusted platform for mission-critical workloads in even the most highly regulated industries.

About the Role

As a Staff Software Engineer on the Secure Compute Platform team, you will be a key technical leader in building and evolving a next-generation, multi-tenant, cloud-native compute platform that safely runs both trusted and untrusted workloads at scale. Our platform is built on Kubernetes and runs across a large fleet of clusters in multiple public clouds, providing a unified abstraction layer for workload execution, lifecycle management, security, and operational excellence.

You’ll work on critical systems including:

• Secure Compute Infrastructure - Build and evolve the secure, multi-tenant compute substrate and isolation primitives that safely execute customer and internal workloads in a shared environment
• Platform APIs & Abstractions - Design and evolve APIs that provide clear, safe abstractions for polyglot workloads (containers, functions, and services) with diverse performance and isolation needs
• Core Platform Integration - Integrate the Secure Compute platform with core data and application services so that teams can onboard new workloads with minimal friction
• Multi‑Tenancy & Security - Implement and harden workload isolation, network policies, identity and access, and secure execution environments required to safely run customer‑supplied code
• Observability & Operations - Drive operational excellence through rich observability, automated health checks, self‑healing workflows, and robust rollout and rollback practices

As a senior technical leader, you think strategically and help drive end‑to‑end technical delivery, from platform APIs and developer experience down to runtime, capacity, and security. You leverage your expertise in cloud‑native distributed systems to take the Secure Compute platform to the next level while ensuring high availability, reliability, security, and cost efficiency for mission‑critical customer workloads.

What You Will Do

• Define and drive the technical direction for Secure Compute, including platform architecture, runtime, and security for running trusted and untrusted workloads at scale
• Design and implement platform APIs and Kubernetes controllers/operators (primarily in Go) that power workload lifecycle, autoscaling, placement, and isolation for containers and serverless‑style functions
• Partner with product and platform teams to shape and deliver the roadmap for Secure Compute, enabling new customer‑facing features and internal platforms to build on a common compute substrate
• Deliver high‑impact initiatives in areas such as workload scheduling, failure and disruption handling, private and public networking patterns, rollout strategies, and fleet‑level resource management
• Lead technical design reviews and influence architecture across teams, ensuring Secure Compute primitives are easy to adopt, safe by default, and aligned with broader platform strategy
• Mentor and grow engineers on the team through design guidance, code reviews, pair programming, and sharing best practices for secure, reliable, operable platform development
