Senior Systems Engineer

TL;DR

Senior Systems Engineer (Linux/Networking): Building the Linux-based edge appliance runtime and distributed control plane for hirify.global One Appliance with an accent on secure networking dataplane, fleet control/state management, and safe device lifecycle operations. Focus on designing resilient, observable systems that tolerate partial failures and deliver customer-critical traffic with production ownership and technical leadership.

Company

hirify.global builds a global network that protects and accelerates internet applications without requiring customers to install software or change code.

What you will do

• Design and implement end-to-end capabilities across the cloud control plane, Linux appliance runtime, telemetry pipeline, and deployment environments (physical, virtual, and public cloud).
• Develop and harden the appliance dataplane and networking platform using technologies such as IPsec, MASQUE, eBPF, and Linux kernel networking primitives.
• Build distributed control-plane and state-management systems for safe configuration/commands delivery, intermittent connectivity tolerance, and zero-touch fleet operation.
• Secure the device lifecycle: hardware-backed identity, attestation, secure boot, immutable OS images, credential rotation, and staged OTA upgrades with safe rollback.
• Make operability a product feature via telemetry, diagnostics, synthetic tests, support bundles, and remote operations.
• Own production outcomes and lead across teams by setting architectural direction, writing proposals, conducting reviews, mentoring engineers, and driving rollout/monitoring/incident follow-up.

Requirements

• 8+ years of professional software engineering experience building and operating complex production systems.
• Strong software engineering skills in Rust, Go, TypeScript, or a comparable language, with willingness to work across the stack.
• Strong Linux systems and networking knowledge (routing, TCP/IP, network namespaces, service supervision, firewall, packet/flow debugging) and secure transport/tunneling tech such as IPsec, WireGuard, GRE, or MASQUE.
• Experience building both Linux-based systems and cloud services, with debugging across network, device, tunnel, control-plane, and upstream-service boundaries.
• Experience designing distributed control planes and reconciliation/desired-state systems for large intermittently connected fleets.
• Security judgment for software deployed inside customer networks (threat modeling, least privilege, credential/key handling, supply-chain integrity, secure lifecycle design).
