About Zelt
Zelt is on a mission to rebuild how organisations run. Our all-in-one platform helps modern companies manage their people across payroll, onboarding, time off, IT provisioning and more, in a seamless and automated way.
We are the only platform on G2 named a Global Momentum Leader across HR, Payroll and IT, and we are just getting started. Our product is technically ambitious, structurally different from anything else on the market, and already trusted by forward-thinking companies.
Why this role matters
As a Senior Fullstack Engineer you will have the opportunity to take features from idea through design to shipped product. You will work in a lean, product-focused team where your input helps shape both what we build and how we deliver it.
What you will do
- Design, build and maintain scalable applications across the stack (Node.js, TypeScript, React, AWS, PostgreSQL)
- Take end-to-end ownership of features including architecture, testing, shipping and iteration
- Collaborate closely with product and design to align technical execution with user needs
- Write clean, maintainable and well tested code and champion engineering best practices
- Improve developer workflows, tooling and processes to keep the team fast and productive
- Stay on top of new technologies and suggest pragmatic, high impact improvements.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
What we are looking for
- Strong experience delivering fullstack applications in fast-moving product environments
- Deep expertise in JavaScript/TypeScript, Node.js, React, AWS, PostgreSQL
- Strong problem-solving ability and attention to code quality and architectural integrity
- Clear communicator who thrives in collaborative environments
- Sense of ownership and pride in your work, motivated by outcomes rather than tasks.

Nice to have

Why join Zelt

- Direct ownership and impact, with your work visible and influential from day one
- A culture that values technical excellence and continuous learning
- Competitive compensation with benefits including health insurance, equity and even airline miles
- The chance to join early enough to shape the product, but with product-market fit and momentum already in place.
At Zelt, your code will not disappear into the background. It will power systems used every day and have a visible impact on how modern companies operate.
