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 Lead 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.
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:
- Startup or scale-up experience in small, fast-moving teams
- Familiarity with CI/CD, observability and scaling infrastructure
- A history of improving performance, code quality or developer experience.
Why join Zelt:
- Work on technically ambitious challenges that will stretch your skills
- 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.
