Base pay range

Full Stack Software Engineer – AI Onboarding Start-Up (Fully-Remote | UK / Europe Timezone | Must Have Right to Work in Indonesia | Competitive Salary)

Company & product

We’re an early-stage AI start-up building a new category : an AI-powered onboarding agent for SaaS companies. Our product spans from Chrome extension, web automation SDK, to web application. We have strong backing from Antler, a Singapore-based VC and are beginning to scale our team.

With our MVP already live, we’re now searching for a Full Stack Engineer to join the core team – someone ambitious, technically exceptional, and ready to help build the company from the ground up. This is a 6-month contract role with a pathway into a full-time role.

Kulu’s mission is to reinvent how SaaS companies onboard their users. We’re building AI agents for web automation.

The engineering team is led by a PhD founder with deep machine learning expertise. Backed by venture capital and with a clear product roadmap, we’re moving fast to shape how onboarding looks in the AI era.

Responsibilities

  • Build and enhance both frontend and backend components of the product
  • Integrate AI features into real-time onboarding workflows
  • Contribute to scalable architecture, deployment, and testing
  • Help shape and deliver new features that push the boundaries of web automation and onboarding

Qualifications

  • 4+ years of experience building and shipping full-stack products end-to-end
  • Strong fundamentals in Python, TypeScript, and database design
  • Proven track record of shipping in fast-paced, product-driven environments
  • Hands-on experience integrating AI / LLM APIs into production workflows
  • AI-native developer : you already code daily with Cursor, Claude, Windsurf, or similar tools to move faster
  • Able to jump between frontend, backend, SDKs, infra, and live debugging — thriving on variety and context-switching
  • Super fast learner
  • Web automation experience (e.g., Puppeteer, Playwright, or DOM-level scripting) is a strong plus

    • Other key requirements

  • Strong English language proficiency
  • Willingness to match UK timezone
  • Willingness to relocate to Bali in the future where we plan to establish a permanent engineering office

    • Tech Stack

  • Frontend : JavaScript / TypeScript, React, Vite (or similar). Ability to design scalable, reusable SDK components. Experience with DOM interaction and web automation (e.g., Puppeteer, Playwright).
  • Backend : Python (FastAPI), building and scaling production-grade APIs (REST, WebSockets). Hands-on with Supabase (Postgres) — schema design, query optimization, and data modeling for scale.
  • DevOps : CI / CD pipelines (Vercel, Render, GitHub Actions), automated testing, and cloud deployments.
  • AI : Practical experience integrating third-party AI / LLM APIs (OpenAI, Anthropic).
  • AI-native workflow : highly proficient with AI-powered IDEs and coding accelerators (Copilot, Cursor, Windsurf, Claude, etc.) to move fast and deliver efficiently.

    • Benefits

  • Competitive salary + a founding-level opportunity
  • High ownership, high trust, and the freedom to shape engineering culture
  • Remote-first, flexible hours
  • The energy, speed, and autonomy of an early-stage start-up – with early customers and strong product-market pull

    • Working at Kulu

    We’re an early-stage startup — we ship fast, learn faster, and embrace the chaos. You’ll be joining at the ground floor, with a chance to shape both the product and the company.

    We’re remote-first and flexible, but we move with urgency. High ownership, high trust, and rapid iteration.
