In-person SF office

Job summary

Engram, based in San Francisco, is seeking an infrastructure engineer to own and evolve the systems that train and serve customer models. You will manage cloud infrastructure from ingestion to training to inference, ensuring strict isolation across customers and seamless collaboration with researchers.

The role requires hands-on experience with AWS, Terraform, and container orchestration, and offers startup equity in a hands-on, early-stage environment with heavy ownership.

Qualifications

• A bachelor’s degree, or equivalent practical experience, in computer science, engineering, machine learning, or a related field.
• Four years of work experience as a software engineer or equivalent, exclusive of internships.
• Experience building and operating production infrastructure on AWS, including IAM expertise: cross-account roles, STS, resource and key policies, KMS, and multi-account organizations.
• Infrastructure-as-Code (Terraform or similar) at multi-account scale, with secure patterns for networks, IAM, and shared services.
• A rigorous approach to multi-tenant isolation.
• A track record of owning complex, production-critical systems end to end.
• Comfort with ambiguity and high ownership at an early-stage company.
• Strong production-grade coding skills (Python, Rust, or similar). This role involves shipping code as well as configuration.

Responsibilities

• Build and operate the cloud infrastructure responsible for training and serving Engram customer models.
• Design and enable the boundaries that keep each customer’s data, training runs, and models separate; both on the cloud and on Engram-managed baremetal compute.
• Partner with researchers and engineers on paved roads that improve our isolation and security posture.
• Evaluate and secure the providers and tools we build on, including Modal, Baseten, and Fireworks as well as compute on baremetal or Kubernetes.
• Take the lead on security operations and customer trust: maintain the logging and monitoring we rely on, respond to incidents, and bring clarity to security reviews and compliance work.
