Senior Design Engineer, Web

About Buildkite

Buildkite’s CI platform is trusted by the world’s leading engineering teams, shipping software to over 1,000,000,000 daily users.

Job Overview

This is a rare “own the whole surface” web role: the chance to run Buildkite’s most visible experience end-to-end, turning brand and product narrative into a fast, beautiful, scalable website.

This newly created role in our Brand team exists to make our web presence fast, elegant, differentiated, and durable; a system that can evolve with our story, showcase real proof, and ship new pages and content without painful rebuilds or fragile hacks.

You’ll own the craft at the intersection of design quality and production-grade frontend engineering, collaborating across the company from product to sales to support and back again.

What You’ll Do

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
