About the company

Our client is a fast-growing software company.

The role

Raydar is recruiting for this role on behalf of our client. Take responsibility for core backend services at a high-scale software platform, shaping them from initial architecture through live operation. Partner with product, design and engineering leaders to untangle unclear technical challenges, and use AI coding assistants as a routine part of daily work.

What you'll do

  • Lead the architecture, delivery and ongoing operation of key services and product capabilities.
  • Develop and maintain distributed data-processing systems, choosing suitable tools such as a message queue and databases for each problem.
  • Turn vague, difficult technical challenges into clear plans and deliver them, staying accountable for uptime, speed and cost efficiency.
  • Create intelligent agent-based software features for a broad global audience.
  • Work with product, design and engineering leadership on problems that span several teams.

What we're looking for

  • 5 to 8 years of professional software engineering experience.
  • Time spent at startups, AI-focused companies or in an early engineering team.
  • A track record of steadily taking on greater scope and responsibility.
  • Experience running high-traffic distributed platforms in production.
  • Solid system design skills for data-heavy, distributed architectures.
  • Working knowledge of Ruby on Rails or Python, plus a document store or search engine.
  • Practical experience using AI coding assistants.
  • Either deep database expertise or experience building applications on large language models, ideally gained at a respected high-growth company.
  • Residence in the San Francisco Bay Area and willingness to be in the office 3 days per week.

Bonus points

  • A computer science degree from a leading university, though extensive hands-on experience can offset this.
  • Flexible hybrid work

Location and work model

  • San Francisco, CA, United States
  • Hybrid, 3 days per week in office
  • Full-time

Compensation, as the posting describes it
