Job Summary

We’re hiring Systems Engineers to build the process-isolation, sandboxing, and network-interception infrastructure that enables secure workload execution across the Kaseya Intelligence Platform. This is low-level engineering at the Linux, networking, and process boundary rather than application-layer development. You’ll build language-independent infrastructure that isolates workloads, protects credentials, and enforces security controls across multi-tenant environments.

Roles & Responsibilities

Build and operate a transparent sidecar proxy that intercepts outbound vendor API calls, enforces credential and compliance policies, and records tamper-evident audit events

Implement process-isolation controls using Linux users and permissions, namespaces, cgroups, ptrace restrictions, protected memory, and explicit credential cleanup

Evaluate and implement sandboxing approaches using technologies such as gVisor, Firecracker, WebAssembly runtimes, or Unix-domain-socket isolation

Design infrastructure that enforces workload and customer boundaries across large numbers of isolated execution environments

Evaluate and integrate workload identity and attestation technologies such as SPIFFE and SPIRE

Implement secure workload startup sequencing, including KMS access, token preparation, network-rule installation, and readiness signalling

Improve the performance, observability, reliability, and failure recovery of the execution and isolation layers

Partner with Platform, Security, and Backend Engineering teams to define interfaces, investigate production issues, and deploy platform improvements

Required Qualifications

Experience developing production systems software using Go, Rust, C, or C++

Experience working with Linux internals, including namespaces, cgroups, netfilter or iptables, sockets, and process lifecycle management

Experience implementing or operating at least one sandboxing or workload-isolation technology, such as gVisor, Firecracker, WebAssembly, containers, or micro virtual machines

Experience building networking infrastructure involving TCP/IP, transparent proxying, or TLS termination and origination

Experience implementing process isolation, privilege separation, protected credential handling, or related operating-system security controls

Preferred Qualifications

Experience building or operating multi-tenant container, sandbox, or virtual-machine isolation infrastructure

Experience with SPIFFE, SPIRE, or another workload identity and attestation framework

Experience integrating AWS KMS, Azure Key Vault, GCP Cloud KMS, or similar key-management services

Experience working on endpoint security, EDR, zero-trust networking, or infrastructure security products

Experience with Kubernetes, container-runtime internals, or managed container platforms

Experience with Temporal or another durable workflow execution platform

Experience supporting systems subject to security, privacy, or compliance requirements
