Building the Future of Open Finance
Payward - the parent company behind Kraken, NinjaTrader, Breakout, xStocks, Payward Services and CF Benchmarks - has spent the last 15 years building one of the most modern and globally accessible financial infrastructure platforms in the industry, built to advance an open, global financial system.
The team
Founded in 2011, Kraken is one of the world's longest-standing crypto platforms, trusted by over 10 million individuals and institutions across the globe. It offers spot trading, margin, futures, staking, and OTC services, with products built for both individual investors and institutional clients.
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
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 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
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
