Senior Design Engineer, Web

Buildkite is a company that provides a CI platform trusted by leading engineering teams. They are seeking a Senior Design Engineer to own the entire web experience, ensuring a fast, elegant, and scalable website that reflects the brand and product narrative.

Responsibilities:

• Own the Buildkite website and CMS end-to-end
• Own the full web experience: information architecture, layout and design, frontend implementation, performance, accessibility, and ongoing quality
• Ensure the website remains a credible, differentiated, product-grade experience that reflects Buildkite’s standards
• Build a component-driven system that scales
• Design and build a reusable component system that stays on-brand and supports new pages, products, and content types
• Establish patterns that make shipping fast while maintaining craft and consistency
• Define and maintain the web platform stack
• Collaborate and lead on the direction of the website stack: framework, styling, build tooling, CI, hosting, analytics, and experimentation
• Set pragmatic standards that keep the platform modern, maintainable, and resilient over time
• Evolve CMS integration and publishing workflows
• Improve how content ships across the org, with safe guardrails and governance
• Build preview environments, validations, reusable modules, and publishing standards that enable broader teams to contribute confidently
• Translate Buildkite’s identity into a living system
• Work embedded in a centralised Brand team to bring typography, motion, interaction patterns, theming, and responsiveness to life
• Ensure Buildkite’s design language is expressed consistently across the web surface
• Partner across the company as the web craft owner
• Collaborate with every org function to ensure the end-to-end Buildkite experience is cohesive, coherent, and compelling
• Align stakeholders while protecting quality, performance, and long-term maintainability
• Establish a sustainable operating model
• Build monitoring, performance budgets, accessibility checks, search hygiene, and documentation
• Create regular reporting and operational cadence
• Run a Web OS that compounds
• You’ll operate with a cadence that scales beyond you - building a web platform that gets sharper, faster, and more undeniable every time we ship:
• Craft loop: interaction, motion, typography; the details engineers feel
• System loop: components and patterns that make new pages inevitable, not bespoke
• Performance loop: speed, accessibility, SEO, reliability; always product-grade
• Publishing loop: CMS guardrails so the org can ship without breaking the surface
• Proof loop: repeatable launches and pages that turn Buildkite’s reality into receipts
• Trust loop: simple metrics that show the site compounding, not drifting
• Represent Buildkite through the web with authority and taste
• Treat the website as our most visible brand experience, not a brochure
• Craft a domain that engineers respect in their bones
• Shape what “good” looks like for Buildkite on the modern web

Requirements:

• Experience extending brand systems across a modern web presence
• Experience with design tooling such as Figma, Sketch, or similar
• Strong frontend engineering background with frameworks such as Astro, Next, Tailwind, or equivalent
• Familiarity with the DevTools and the DevOps ecosystem, understanding what credibility looks like for technical audiences
• Proven ability to tackle complex problem-solving, independently or collaboratively
• Clear communication skills; able to explain technical decisions to both engineers and non-technical stakeholders
• High empathy and strong async collaboration instincts in a remote-first environment
• Experience with AWS S3, CDNs, Brotli, or modern web delivery infrastructure
• Familiarity with experimentation, analytics, and web performance tooling
• Deep understanding of CI concepts and modern developer workflows
