• Work closely with senior engineers to break work down, ship iteratively, and learn good engineering habits.
• Improve front end developer experience through small tooling, testing, and workflow improvements.
• Write clear, maintainable code and learn how we think about quality, performance, and accessibility.
• Contribute to team discussions, ask questions early, and share what you learn.
• Use AI tools thoughtfully - Leverage AI to move faster for example drafting code, exploring solutions, or writing tests, while applying good judgement and always reviewing what ships.

Our Techstack

AI is reshaping how software gets built, and at Karbon we’re fully committed. We don’t see AI as a replacement for engineers. We see it as a force multiplier that will elevate creativity, impact and capability to levels we’ve barely begun to imagine. We’re looking for developers who are confident in their fundamentals, driven to grow, and excited to harness AI to build something meaningful. If you’re energized by this future rather than cautious of it, you’ll feel right at home here.

Karbon embraces diversity and inclusion, aligning with our values as a business. Research has shown that women and underrepresented groups are less likely to apply to jobs unless they meet every single criteria. If you've made it this far in the job description but your past experience doesn't perfectly align, we do encourage you to still apply. You could still be the right person for the role!

We recruit and reward people based on capability and performance. We don’t discriminate based on race, gender, sexual orientation, gender identity or expression, lifestyle, age, educational background, national origin, religion, physical or cognitive ability, and other diversity dimensions that may hinder inclusion in the organization.

Generally, if you are a good person, we want to talk to you. 😛
