Senior Golang Engineer

Senior Go Software Engineer - Remote from Poland

Role Overview

We are looking for a Senior Software Engineer to design, build, and secure our core infrastructure and platform tooling.

In this role, you will lead the development of critical systems in Go, engineer cross-platform build pipelines, and implement low-level security boundaries. You will work extensively with internal build, testing, and cloud technologies to ensure high reliability, security, and isolation across Linux, macOS, and Windows environments.

Location: Remote from Poland

Key Responsibilities

• Core Development: Write robust, production-grade Go code and build console/shell automation to manage local and cloud environments.

• Build Systems & Cross-Compilation: Configure and maintain Blaze/Bazel build systems to compile and cross-compile binaries targeting Linux, macOS (ARM), and Windows (x86).

• CI/CD & Pipeline Orchestration: Design and maintain complex build and test workflows using Rapid and Kokoro, including dynamic provisioning of ephemeral GCE VMs for end-to-end integration testing.

• OS-Level Security & Sandboxing: Implement process isolation and security boundaries using native platform technologies, including Linux Bubblewrap, macOS Seatbelt, and Windows AppContainer.

• Environment Provisioning: Integrate ephemeral GCP test project checkouts through Project Rental Service (PRS) to reduce quota collisions and improve test reliability across suites.

Required Qualifications

• Extensive hands-on software development experience with Go and console/shell scripting.

• Proven experience with Blaze/Bazel, including cross-compilation for Linux, macOS (ARM), and Windows (x86).

• Practical experience designing and orchestrating release and test pipelines using Rapid and Kokoro.

• Deep familiarity with operating system security controls and sandboxing mechanisms, such as Linux Bubblewrap, macOS Seatbelt, and Windows AppContainer.

• Hands-on experience automating cloud infrastructure and ephemeral test environments using GCE VMs.

Desired / Preferred Qualifications

• Hermetic Testing: Experience configuring ITS to execute "in-a-box" functional tests on BorgLite with faked dependencies such as IAM and Spanner, including the use of CCFE rollback testing macros.

• E2E & Integration Testing: Familiarity with non-hermetic E2E post-submit validation against real staging dependencies using the Guitar framework.

• Cloud Resource Orchestration: Hands-on experience with Project Rental Service (PRS) for dynamic GCP test project management.

• Observability & Networking: Familiarity with modern proxy, telemetry, and observability technologies such as Envoy and OpenTelemetry.
