    Original listing · kept for reference

    We are seeking a talented Senior AI & Backend Engineer to design and scale the server-side foundation of our next-generation platform. In this role, you will bridge the gap between high-scale distributed backend systems and advanced LLM architectures. You will take end-to-end ownership—from writing high-concurrency microservices and orchestrating complex agentic workflows to managing production deployments on Kubernetes.

    Core Responsibilities

    • High-Performance Services: Architect, build, and optimize scalable backend microservices utilizing Python, FastAPI, and async messaging patterns.

    • Agentic & AI Infrastructure: Design durable, multi-step LLM workflows, autonomous agent frameworks, and high-retrieval RAG pipelines.

    • Resilient Workflows: Implement durable execution engines (such as Temporal) to ensure fault-tolerant, long-running processes across distributed services.

    • Data Layer Management: Model, maintain, and optimize PostgreSQL databases, creating clean schema migrations (using ORMs like Drizzle) to support evolving product features.

    • Cloud & Platform Operations: Own the deployment lifecycle, containerizing services, and scaling workloads on managed Kubernetes (EKS) environments.

    • Technical Leadership: Lead architectural discussions, conduct thorough code reviews, and drive system reliability and incident resolution.

    What You’ll Bring

    • 4+ years of professional experience engineering complex software applications in production.

    • Modern Python Proficiency: Deep hands-on experience with asynchronous Python development, FastAPI, and high-concurrency paradigms.

    • Applied AI Engineering: Proven track record of architecting real-world LLM applications, RAG systems, and agent frameworks (focusing on system architecture rather than basic prompt engineering).

    • Relational Database Expertise: Strong proficiency with PostgreSQL, query optimization, and modern ORM abstractions.

    • Infrastructure & DevOps Foundations: Practical experience with Docker, Kubernetes (EKS), and CI/CD pipelines.

    • Mindset: An exceptional problem-solver who thrives in greenfield ("zero legacy") environments, value-driven execution, and team-first engineering culture.
