About the company

Our client is a fast-growing software company.

The role

Raydar is recruiting for this role on behalf of our client. Act as a hands-on senior engineer who owns the customer-facing side of a web application, carrying features from first prototype through release with care for polish and speed. Work side by side with leadership and cross-functional colleagues while raising the bar for code quality and coaching other engineers.

What you'll do

  • Design and build full-stack features, including refined user interfaces, dependable APIs and scalable backend services.
  • Take product features from early prototype to launch, paying close attention to responsiveness, usability and visual finish.
  • Collaborate with product, sales, marketing and leadership to connect third-party generative AI models through their APIs and open up new use cases.
  • Translate design mockups into polished, production-ready interfaces.
  • Lead large product initiatives from concept to release, including upcoming launches.
  • Define coding conventions and quality practices for the team, and coach colleagues through your own example.

What we're looking for

  • 5 to 10 years of professional experience delivering full-stack web products.
  • Industry experience with TypeScript and AWS, including React front ends and Node.js back ends.
  • Background building full-stack systems that scale, such as data-heavy processing, search and retrieval, or background job workflows.
  • At least 12 months of professional experience building LLM-based or agent-based products at a startup or AI-focused company; personal projects do not count.
  • Startup experience; a career spent only at large technology companies is not a fit.
  • A portfolio of shipped interfaces or products that demonstrates strong product sense and visual taste.
  • Solid computer science fundamentals, including system design, algorithms and application architecture.
  • A formal computer science or engineering degree.
  • Fluent English for reading, writing and speaking.
  • A record as a hands-on technical lead who raises standards and helps mid-level engineers grow.
  • Ability to work on-site five days a week in a fast-paced startup and start in the office right away.

Bonus points

  • Familiarity with working on media or video technology.
  • Experience with consumer-facing generative AI products.

Benefits

  • Health, dental and vision coverage

Location and work model

  • San Francisco, CA, United States
  • On-site, 5 days a week in the office
