Job description
from Perplexity careersPerplexity is looking for experienced Backend Engineers to build the foundational systems behind our core products. As we move toward agentic products that can reason, delegate, use tools, and execute complex workflows, backend engineering is one of the most important parts of making that experience reliable at scale. You’ll help design and operate the systems that connect models, data, product surfaces, and infrastructure into a platform millions of people and companies can depend on.
We’re hiring across several backend teams, and we’ll match you with a specific group after you complete the interview process, factoring in both your background and what you’re excited to work on. This lets us place engineers where their skills and interests line up with the highest-impact backend product work and the strongest opportunities for growth.
