Software Engineer, Design System - Fixed Term Mat Contract

At Serko, we believe something incredible happens when people come face-to-face. That’s why we’re on a mission to engineer a frictionless, next-generation business travel marketplace. We don’t just manage travel; we are leveraging advanced AI and cutting-edge tech to eliminate the complexity of global movement.

When you join Serko, you join a global collective of passionate technologists who show up as their true selves to build world-class products. With established hubs across New Zealand, Australia, North America, India and China - your code and ideas will impact millions of corporate travelers worldwide.

Reporting to a Senior Engineering Manager or Engineering Manager and working alongside a supportive team, you deliver well-defined parts of Serko's design system: the components, tokens, patterns and guidance that every product team, and a growing number of agents, build on.

Join a self-organizing design system team that builds the foundations for our product experiences. You will own your roadmap from opportunity to adoption, driven by high agency and a strong consumer mindset.

• High Agency & Bias to Action: Drive your own work, make fast decisions, and ship small changes often.
• Systems & Consumer Mindset: Build scalable foundations that make it effortless for product teams to do the right thing.
• Curiosity & Clear Communication: Learn fast, reason through complex problems, and articulate your decisions.
• AI-Empowered: Leverage AI tools daily to accelerate both your workflow and the team's overall velocity.
  
  

• →End-to-End Ownership: Independently deliver accessible, high-quality components. Own everything you ship from initial scoping and release through to adoption and support.
• →Pioneer Agentic Engineering: Work agentically by default. Direct AI tools with clear requirements, write test-first code, and make our system highly legible to both humans and AI agents.
• →Seamless Collaboration: Partner closely with Design and Engineering. Write clear guidance and evolve our foundations without disrupting the teams that rely on them.
• →Agile Execution: Break complex problems into small, shippable slices. Lead smaller projects, make fast (and reversible) decisions, and continuously improve how the team builds.
  

• Core Stack: Solid production experience with React, TypeScript, and Tailwind CSS.

• Design Systems & UI: Deep understanding of component architecture, API design, and design tokens (Figma to code). You build simple, maintainable solutions with a sharp eye for design details.
• Quality & Accessibility: Proven ability to build to WCAG AA 2.x standards, backed by robust automated testing (unit, interaction, and visual regression).
• Agentic Engineering: Experience with (or strong curiosity about) context engineering, verification loops, and structuring code and documentation to be seamlessly consumed by both humans and AI agents.
• Engineering Excellence: A proactive collaborator who plans effectively, supports peers through code reviews, and balances speed with quality while taking ownership of your own growth.
