Our client is a fast-growing software company.

The role

Raydar is recruiting for this role on behalf of our client. Own the design and full-stack build of a customer-facing web application, partnering directly with company founders. The work spans interface design, engineering, release and go-to-market content, shaped by usage data and customer input.

What you'll do

  • Build and maintain a web application across front end and back end, using TypeScript and Python.
  • Design clear, polished interfaces that make complex systems easy to use.
  • Carry each feature from early customer discovery and prototypes all the way to release.
  • Create demos, release materials and promotional campaigns for what you ship.
  • Maintain high standards for design quality, performance and delivery speed.
  • Use product analytics and customer feedback to prioritize upcoming work.

What we're looking for

  • At least 3 years of full-stack engineering experience.
  • Solid UI and UX skills, with strong product judgment and care for detail.
  • A track record of launching a brand-new product from scratch.
  • Hands-on experience building with large language models and agent-based systems.
  • Clear writing and a good instinct for how to position and promote a product.
  • Self-directed approach, able to spot problems and resolve them without supervision.
  • Existing US work authorization.

Bonus points

  • Past founder or early-stage startup engineering background.
  • Exposure to tools built for developers or AI-first applications.
  • Familiarity with agent orchestration or SDK design.
  • Background in creating video walkthroughs, demos or technical write-ups.
