Job description:  Principal Dev Tooling Engineer (Must: CLI & GO)

We are building a next-generation API Review Agent platform and developer tooling ecosystem. The platform enables engineers to validate, review, govern, and automate API quality using AI-powered workflows. Our vision extends beyond backend services—we are creating world-class CLI tooling, SDKs, plugins, and developer experiences that can be distributed globally and adopted across thousands of engineers. 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 for API governance, review automation, developer workflows, and platform operations.
- Create extensible plugin architectures and SDKs for internal and external consumers.
- Design and implement software distribution strategies across macOS, and Windows.
- 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 follows 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 excellent 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:

- Strong proficiency in Golang and TypeScript/Node.js.
- Experience building and maintaining production-grade CLI applications.
- Deep understanding of software packaging and distribution technologies (Homebrew, npm, standalone binaries, installers, containers, etc.).
- 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.
- Advanced English is required for this position.

Preferred Experience:

- Developer platform engineering.
- AI-assisted tooling and agent-based workflows.
- Software supply chain and artifact distribution.
- Cross-platform desktop tooling.
- Open-source tooling ecosystems.
- Enterprise telemetry and analytics platforms.
- API governance and developer portals.
