We are looking for engineers who are passionate about developer productivity, command-line tooling, software distribution, observability, and telemetry. You should be equally comfortable building Go-based CLIs, TypeScript developer tooling, release automation, update mechanisms, and analytics pipelines that help teams understand how tooling is used in production.

Responsibilities

• Design and develop production-grade CLI tools using Golang and/or TypeScript
• Build command-line experiences supporting API governance, review automation, developer workflows, and platform operations
• Create extensible plugin architectures and SDKs for both internal and external consumers
• Design and implement software distribution strategies across macOS and Windows environments
• Build release pipelines, package managers, installers, auto-update mechanisms, and version management solutions
• Implement telemetry frameworks that measure adoption, usage patterns, performance, reliability, and feature engagement
• Ensure telemetry collection adheres to privacy, compliance, and enterprise governance requirements
• Develop authentication, configuration, and credential-management capabilities for developer tools
• Build integrations with GitHub, GitLab, CI/CD systems, IDEs, and developer portals
• Create high-quality documentation, tutorials, examples, and developer onboarding experiences
• Participate in architecture reviews, code reviews, and platform-wide engineering initiatives
• Drive reliability, scalability, security, and maintainability across the tooling ecosystem

Qualifications

• A minimum of 3 years of relevant experience
• Strong proficiency in Golang and TypeScript/Node.js
• Experience building and maintaining production-grade CLI applications
• Deep understanding of software packaging and distribution technologies, including Homebrew, npm, standalone binaries, installers, and containers
• Experience implementing telemetry, analytics, and usage instrumentation within developer tools
• Knowledge of OpenTelemetry, metrics collection, logging, and observability best practices
• Experience with release engineering, CI/CD automation, and artifact management
• Strong understanding of API design, OpenAPI specifications, and developer experience principles
• Experience building SDKs, plugins, extensions, or developer productivity platforms
• Knowledge of authentication mechanisms, including OAuth, API keys, and enterprise SSO integrations
• Experience working with cloud-native and distributed systems
• Excellent written and verbal communication skills
• Ability to work independently in ambiguous environments and drive technical decisions
• Upper-Intermediate English language competency (B2)

Requirements

• Experience with AI solution engineering
• Background in developer platform engineering
• Familiarity with AI-assisted tooling and agent-based workflows
• Experience with software supply chain management and artifact distribution
• Background building cross-platform desktop tooling
• Experience contributing to or maintaining open-source tooling ecosystems
