Staff Backend Engineer

The AI engineers are building the brains — you’ll architect the nervous system. You’ll work shoulder-to-shoulder with AI engineers, product designers, and founders to ship modular, scalable, battle-tested backend systems that power autonomous agents in enterprise environments. Bonus: Using AI tools to boost your own efficiency isn't optional — it's expected.

What You’ll Do:

• Design, build, and scale backend systems powering AI orchestration engines (APIs, state management, async job queues, task planners).
• Integrate LLM-based agents, RAG pipelines, vector stores, and multi-agent orchestration tools.
• Build platform capabilities including: Agent identity management & secure credentials; Agent task routing and lifecycle management (e.g., Temporal); Modular plugin and tool-execution infrastructure; Own API and service architecture for frontend apps, third-party APIs, and enterprise clients.
• Optimize for performance, observability, and reliability (thousands of real-world workflows daily).
• Champion clean code, testing, CI/CD, and documentation.
• Contribute to platform-level architecture decisions (event streaming, memory persistence, auth layers, deployment pipelines, cloud infra).
• Mentor engineers and raise the bar across quality and velocity.

What You Bring:

• 9+ years backend engineering experience designing scalable distributed systems.
• Deep expertise in Java (microservices, serverless, etc.).
• Strong experience with PostgreSQL, Redis, Kafka, REST APIs.
• Hands-on experience with workflow orchestration tools like Temporal (or similar).
• Strong knowledge of GCP, Docker, Terraform, cloud-native architectures.
• Builder's mindset — thrive in 0→1 environments.
• Excellent communication skills and cross-functional collaboration experience.
