Software Engineer II - Frontend - Developer Platform

As a Software Engineer II on the Developer Platform team at Kraken, you help make web development faster and more reliable across the organization. Kraken, founded in 2011, is one of the world's longest-standing crypto platforms trusted by over 10 million individuals and institutions globally. You work on the infrastructure, tooling, and delivery systems that enable engineers to build and ship products efficiently.

What you'll do

• Make web development faster by improving builds, type checking, linting, and tests, both locally and in CI
• Evolve the 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
• Experience improving developer tooling, build systems, automated testing, or CI/CD pipelines, and the ability to diagnose problems across those layers
• 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 have

• 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
• Hands-on experience with coding agents and improving the environments, documentation, and feedback loops they rely on
• Experience with GitLab CI, containers, or cloud infrastructure supporting web development and delivery
• Contributions to open-source frontend infrastructure or developer tools
