Why This Job is Featured on The SaaS Jobs
Karbon sits in a well-established B2B SaaS category—practice management for accounting firms—where product work is shaped by long-lived customer workflows, reliability expectations, and incremental modernisation. This role stands out because it is anchored in a frontend platform concern: migrating from Ember to React while improving the internal developer experience that supports ongoing feature delivery.
For a SaaS engineer, that combination builds durable skills. Migration work forces clear thinking about compatibility, rollout strategy, and maintaining product velocity while changing foundations. Exposure to Next.js conventions, shared design systems, and performance/accessibility considerations mirrors how many SaaS products standardise UI across large surfaces. The emphasis on tooling, testing, and workflow refinements also maps closely to how SaaS teams reduce lead time and improve quality at scale.
This position is best suited to early-career frontend engineers who want structured proximity to senior engineers and are motivated by iterative shipping rather than greenfield-only work. It will fit someone who enjoys learning modern React patterns, values maintainability, and is comfortable balancing feature needs with platform improvements in a product-led SaaS environment.

Job Description
About Karbon & the role
Karbon builds practice management software used by accounting firms worldwide, with a collaborative cloud platform and customers in 34+ countries supported by a globally distributed, fast-growing team.
We’re hiring a Junior Frontend Engineer to join our Front End Developer Experience (FEDx) team in Sydney. You’ll help migrate parts of our product to React and improve the day-to-day experience of building and shipping front end at Karbon.
This is a great role for someone hungry to learn, keen to take ownership, and excited to make an impact early.
What you’ll do
- Build new React UI and help migrate existing screens and components to React.
- Work with Next.js patterns where it makes sense (routing, layouts, data fetching approaches, page performance).
- Build consistent UI and learn how we maintain a shared design system.
- Use AI tools to move faster (for example: drafting code, exploring options, writing tests), while applying good judgement and always reviewing what ships.
- 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.
Our tech
- Frontend: React, TypeScript, and Ember (during the migration). Next.js, TanStack Query, Tailwind, shadcn (where applicable)
- Backend: .NET (C#, .NET Core, Web API) with SQL Server
What you’ll bring
We know great engineers come from many backgrounds. You don’t need to tick every box below to apply.
- You’ve built something in React (personal projects, study, internships, or commercial experience).
- Curiosity and a strong learning mindset. You enjoy feedback and want to get better fast.
- A bias toward action. You like shipping, iterating, and finishing what you start.
- Clear communication. You can explain what you’re doing, what’s blocked, and what you need.
- Care for the craft: readable code, small pull requests, and pride in quality.
Nice to have
- Next.js experience (even at a basic level).
- TypeScript experience.
- Experience with Tailwind or component libraries.
- Exposure to automated testing (unit, integration, or end-to-end).
- Experience working in a product team with designers and product managers.
- Any experience with migrations, refactors, or improving existing code.
Why Work at Karbon?
- Gain global experience across the USA, Australia, New Zealand, UK, Canada and the Philippines
- 4 weeks annual leave plus 5 extra "Karbon Days" off a year
- Flexible working environment
- Work with (and learn from) an experienced, high-performing team
- Be part of a fast-growing company that firmly believes in promoting high performers from within
- A collaborative, team-oriented culture that embraces diversity, invests in development, and provides consistent feedback
