Design, build, and operate the Linux-based edge appliance runtime and distributed control plane. Implement secure networking dataplanes (IPsec, MASQUE, eBPF), reliable fleet control and remote lifecycle management, telemetry and diagnostics, and drive product-focused technical leadership from architecture through rollout and incident response.

Lead Perforce Helix Core administration to ensure high availability, scalability, and data integrity. Optimize infrastructure, automate tasks with IaC and scripting, support CI/CD integrations, provide high-level troubleshooting and training, and collaborate with development teams to improve version control workflows and disaster recovery.

Design and build a global, serverless AI inference platform running on heterogeneous GPUs and accelerators. Optimize model scheduling, request routing, caching, and load balancing for low latency. Improve reliability and observability, lead cross-functional projects, and mentor junior engineers.

Develop and improve the Workers runtime: build features, expand JavaScript and WebAssembly support, optimize performance and scalability, own production code, and debug large-scale Linux-based distributed systems in an iterative environment.

Design, build, and operate Cloudflare's distributed storage and database products (R2 Data Catalog, R2 SQL). Own full lifecycle delivery, architect consistency models, optimize storage engine performance, design APIs, and debug large-scale distributed systems using Rust, TypeScript, Go, C++, and Linux/UNIX.

The Senior Systems Engineer role involves troubleshooting, maintaining, and supporting AI compute hardware platforms while collaborating with engineering teams for reliability and performance.

Lead design and implementation of data architecture and scalable storage solutions, drive AI/GenAI thought leadership, oversee data governance and security, translate business requirements into technical plans, implement FastAPI endpoints, enhance LLMs through prompt engineering, and manage cross-functional teams to deliver advanced data and AI solutions.

As a Senior Systems Engineer, you'll design high-performance data management systems, optimize for scalability, solve distributed challenges, and collaborate with the team to maintain code quality. Requires strong backend development and systems programming expertise, particularly in Rust.

Lead design and delivery of enterprise integrations, automation, and AI-driven workflows across SaaS platforms. Architect scalable APIs, middleware, and conversational self-service experiences; partner with Security, Infrastructure, and Product; mentor engineers and drive long-term platform strategy, governance, and operational excellence.

Design, build, and operate backend services that enforce regional data residency across a globally distributed edge. Own end-to-end features from design and implementation to rollout and production operations, collaborate across platform, cryptography, and product teams, reason about failure modes and compliance tradeoffs, participate in on-call incident response, and raise engineering standards through reviews and mentorship.

Design, build, and deploy a lightweight, high-performance network sensor for OT/ICS environments. Lead system-level design, packaging, CI/CD, kernel and systemd tuning, container and cloud integration, production support, and cross-team collaboration to ensure maintainability and secure deployments.

Seeking a Senior Systems Engineer proficient in Active Directory, Microsoft, and VMware to support IT operations in a healthcare environment.

Develop and own DSP and algorithm blocks to mitigate analog impairments for analog compute-in-memory: calibration, non-linearity compensation, offset correction, and error estimation. Build Python frameworks and firmware, improve simulation fidelity, correlate silicon and simulation errors, and lead silicon bring-up, characterization, and productization with cross-functional teams.

Lead MBSE activities across the systems engineering V-cycle: develop requirements, SysML models, architecture, verification/validation and certification artifacts (ARP4754B/ARP4761A). Support CDR, risk mitigation, compliance, and mentor junior staff.

Design, build, monitor, and maintain large-scale Linux infrastructure supporting distributed S3-compatible object storage across multi-cloud environments. Responsibilities include kernel and storage optimization, network and hardware troubleshooting, automation with Chef or Ansible, observability, forecasting capacity, technical leadership, project coordination, mentoring, documentation, and on-call support.

Build production-grade backend services and serverless APIs for contact center systems. Implement integrations, observability pipelines, AI-enabled workflows, migration tooling, and reusable platform patterns to improve routing, agent support, reliability, and operational visibility.

Lead systems architecture, define and manage hardware/software/PLD requirements, perform system integration, verification and validation for safety-critical avionics control systems. Support proposals, produce technical documentation, and present to customers.
