The role

Raydar is recruiting for this role on behalf of our client.

• Plan platform designs that hold up under heavy load, with dependable operation and fast response times.
• Shape architecture and engineering decisions that span several teams.
• Explain technical tradeoffs clearly to colleagues outside engineering.
• Build backend components that support AI-driven automation features.

What we're looking for

• Senior or staff-level backend engineering experience.
• A track record of personally building and shipping backend systems in production, not only leading others who did.
• Experience working with LLMs, AI or machine learning systems, or agentic workflows.
• A history of influencing engineering decisions across teams.
