Join the Kaseya growth rocket ship and see how we are #ChangingLives!

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

Compensation Range — Toronto Posting Only

The base salary range for this job is CAD $160,000 – $240,000 / year.

An individual's base pay depends on various factors including geographical location and review of experience, knowledge, skills, and abilities of the applicant. At Kaseya, certain roles are eligible for benefits and additional rewards. These rewards are allocated based on individual impact in role. In addition, certain roles also have the opportunity to earn sales incentives based on revenue or utilization, depending on the terms of the plan and the employee's role.

Additional Information

Kaseya provides equal employment opportunity to all employees and applicants without regard to race, religion, age, ancestry, gender, sex, sexual orientation, national origin, citizenship status, physical or mental disability, veteran status, marital status, or any other characteristic protected by applicable law.
