So far, we’ve contributed over $18 million to fund sanitation projects around the globe. We need people like you to join our mission and ensure everyone around the world has access to clean water and a toilet.

As a genuine remote-first company, we lean into being a high-functioning distributed team. We recognise some people achieve maximum productivity and work-life balance being fully remote. We have a strong culture of trust, and we love to deliver and delight!

Our engagement surveys (thanks Culture Amp!) tell us that our team is really proud (95%) to work for Who Gives A Crap and, well, we couldn’t be more proud of that.

A bit about the team Our Digital Product teams drive the technology and experiences for first-time and returning customers of Who Gives A Crap. As a Senior Software Engineer, you’ll be a technical leader, writing clean, maintainable code across the full stack while mentoring others and architecting scalable solutions. You’ll play a key role in pushing our initiatives forward, balancing rapid innovation with engineering excellence.

If you’re passionate about growth and innovation, and looking to leverage cutting-edge tools to solve complex problems, we’d love to have you on our team!

Have you made it this far? If you’re still reading, we think there’s a strong chance you might be our kind of person.

Here’s the thing, though — research suggests that 60% of women and underrepresented folks might have already talked themselves out of applying. Even if you don’t check every box above, we want to encourage you to introduce yourself.

We believe a diversity of perspectives and experiences makes a team stronger — and the stronger our team, the closer we are to delivering toilets and clean water for all.

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

• 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

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

• Close the gap between concept and shipped product

Shape the practice of Design Engineering at Buildkite

• Contribute to our Design Engineering and front-end workflows, tools, and best practices
• Support these practices as meaningful levers for business impact

Translate brand into lived product experience
