Job Summary

We’re hiring Platform Backend Engineers to build the services connecting workflow execution, identity, event routing, secrets management, and audit infrastructure within the Kaseya Intelligence Platform. This is hands-on backend engineering in Go or Rust for a platform used by other engineering teams and agentic AI workloads. Correctness, reliability, security, and operational clarity are core design requirements for everything you build.

Roles & Responsibilities

• Build and operate platform services supporting API access, Kafka-based event routing, workflow execution, machine identity, and immutable audit records
• Design event-driven workflows that convert PSA webhooks, RMM alerts, and platform events into durable execution using Kafka and Temporal
• Implement a pluggable secrets-management and KMS abstraction supporting multiple cloud providers, bring-your-own-key models, envelope encryption, and customer-level cryptographic isolation
• Build capability-grant enforcement for individual customers, workflows, operations, and service-to-service requests
• Own GitOps-based deployment pipelines for versioned workflow definitions across isolated customer environments
• Develop onboarding automation for identity provisioning, compliance configuration, and customer-specific key-management setup
• Build secure connector services for third-party APIs, including scoped access, managed credentials, request validation, and pre-execution audit logging
• Improve platform observability, performance, failure recovery, operational readiness, and production incident response

Required Qualifications

• Experience building and operating production backend services using Go or Rust
• Experience designing event-driven systems using Kafka or similar technologies, including retries, idempotency, replay, and at-least-once delivery
• Experience implementing authentication and authorization using OAuth 2.0, OIDC, token lifecycle management, or fine-grained access controls
• Experience implementing encryption or key-management solutions using cloud KMS platforms, envelope encryption, or key-hierarchy designs
• Experience operating multi-tenant production systems using structured logging, metrics, distributed tracing, and incident-response practices

Preferred Qualifications

• Experience with Temporal or another durable workflow orchestration platform
• Experience integrating identity platforms such as Zitadel, Keycloak, Auth0, Okta, or similar technologies
• Experience with ClickHouse or another columnar, append-only, or audit-focused database
