Team8 Stealth Mode Startup-Senior Backend Engineer

Description:

About the Role

We’re a stealth-mode startup backed by Team8 and founded by AI industry leaders. 

We transform agent evaluation, guardrails, and optimization into a fast, systematic, CI/CD-like pipeline. We’re building the trust and reliability layer for next-generation AI agents, and we are deeply shaping the future of how companies build, deploy, and improve intelligent systems.

As a Senior Backend Engineer, you’ll design and implement core components of our platform - from scalable data pipelines and evaluation engines to real-time observability and agent-monitoring infrastructure. You’ll join a high-caliber engineering organization built on excellence, ownership, and deep technical curiosity. This role is highly hands-on and sits at the intersection of infrastructure, AI systems, and developer experience.

Key Responsibilities

• Design and develop backend services powering large-scale agent evaluation, monitoring, and optimization pipelines.
• Build high-reliability, low-latency microservices that handle complex AI workflows and high-volume data ingestion.
• Work closely with the AI and product teams to design new capabilities that push agent reliability and safety boundaries.
• Optimize performance across data processing layers, cloud infrastructure, and API surfaces.
• Contribute to technical system design, coding standards, and overall engineering excellence.

• 5+ years of backend engineering experience.
• Strong proficiency in TypeScript, Python, cloud-native services, and high-scale data processing systems.
• Experience building distributed, production-grade solutions.
• Strong engineering fundamentals, ownership mindset, and comfort working in fast-moving environments.

Advantage

• Experience with Kubernetes (K8s), Go, or Rust.
• Background in AI/ML products, LLM-powered systems, or agentic architectures.
• Experience with high-observability, high-reliability systems.
• Familiarity with CI/CD automation, evaluation pipelines, or data-intensive systems.
