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.

Requirements

- 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.
