Kraken

The opportunity

• Make web development faster by improving builds, type checking, linting, and tests, both locally and in CI
• Evolve our monorepo, package management, and shared configuration so changes across applications and libraries are straightforward and reliable
• Simplify development environment setup and support parallel work by engineers and coding agents, with clear documentation and tools that work with minimal configuration
• Improve web delivery pipelines, including preview environments, progressive rollouts, production monitoring, and reliable rollback
• Strengthen automated validation, including browser-based checks that help engineers and agents verify changes before they ship
• Work with product and infrastructure teams to investigate web performance, improve observability, and address problems across application code, tooling, and delivery
• Lead tooling upgrades and migrations across teams, balancing long-term improvements with the practical needs of engineers shipping products
• Own improvements from design through rollout and ongoing maintenance, staying close to the people using what you build

What you bring

• Solid experience building and maintaining production web applications, with a strong understanding of React and the modern JavaScript ecosystem
• Strong TypeScript and JavaScript skills, including experience using Node.js to build tooling and automation
• A good understanding of how web applications work, including browser behavior, module systems, bundling, caching, and performance

• Good judgment about reliability, security, maintainability, and when added complexity is worth the cost
• The ability to lead a technical design, explain it clearly, and work with other teams to get changes adopted
• Ownership: you can take an ambiguous problem, find a practical solution, and keep it working once people depend on it

Nice to haves

• Experience maintaining large monorepos, shared packages, or tooling used by multiple engineering teams
• Familiarity with pnpm, ESM, and modern build, linting, and test tools
• Experience with browser automation, end-to-end testing, web performance profiling, or production observability
