Senior Software Engineer

Senior Software Engineer, Platform Infrastructure (Distributed Systems & Security)

Position Overview

A global leader in cloud-native infrastructure is seeking a Senior Systems Engineer to architect and build a next-generation security platform from the ground up. This team is responsible for developing a high-performance, memory-safe engine that serves as the backbone for global enterprise connectivity. If you view high-performance concurrency as a way of life and believe that systems-level code should be as secure as it is fast, this role offers the opportunity to work on a mission-critical platform protecting millions of users worldwide.

Key Responsibilities

• Foundational Development: Architect and implement core infrastructure components using Rust, focusing on high-throughput and low-latency performance.
• Distributed Systems: Design resilient, horizontally scalable services capable of handling massive data volumes within a global security data lake.
• Systems-Level Engineering: Develop low-level software that interacts directly with Linux internals, networking stacks, and kernel-space interfaces.
• Operational Excellence: Ensure system reliability through rigorous performance instrumentation, observability, and automated CI/CD workflows in containerized environments.

Technical Requirements

• Systems Programming: Expert-level proficiency in Rust, with deep experience in asynchronous programming (Tokio or similar frameworks).
• Linux Fundamentals: Strong understanding of Linux internals, including sockets, namespaces, and memory management.
• Distributed Architecture: Proven success in building and maintaining large-scale, high-availability distributed systems.
• Tooling: Experience with Docker, Kubernetes, and modern performance profiling tools.

Preferred Experience

• Networking Mastery: Familiarity with L2-L4 protocols (TCP/IP, QUIC) or kernel-space technologies such as eBPF or DPDK.
• Polyglot Systems Skills: Prior experience with C/C or Go in performance-critical or security-focused environments.
• Protocol Design: Hands-on experience with gRPC and Protobufs for efficient service-to-service communication.

Benefits & Environment

• Culture: A collaborative, hybrid-working environment that values technical craftsmanship and inclusive engineering practices.
• Growth & Support: Comprehensive health plans, retirement options, and professional development/education reimbursement.
• Impact: The opportunity to build a brand-new platform from scratch that defines the next generation of secure internet infrastructure.
