ABOUT THE ROLE

We're looking for a Backend & Cloud Infrastructure Engineer to help build and scale the systems behind Sekai. In this role, you'll work across backend development and cloud infrastructure, building high-performance APIs, supporting AI/LLM workloads, and ensuring our platform is scalable, reliable, and efficient.

You'll have end-to-end ownership, from designing core backend services to optimizing AWS infrastructure and improving overall system performance. It's a great opportunity for someone who enjoys both building products and solving complex infrastructure challenges in a fast-moving startup environment.

RESPONSIBILITIES

Backend Development

Own the architecture, development, and evolution of core backend services. Write high-quality code in Python / Go, and lead design reviews and code reviews.
Design and build high-performance, highly available RESTful / gRPC APIs that serve high-traffic consumer features and AI / LLM workloads.
Design and tune async task processing and message queues (Kafka, Celery, SQS, etc.) for throughput and data consistency.

Cloud Platform & Reliability

Plan, build, and govern our AWS infrastructure (ECS / Lambda / RDS / S3 / CloudFront / VPC, etc.), and drive Infrastructure as Code with Terraform or similar tools.
Build and improve monitoring, logging, and alerting (Datadog, CloudWatch, Sentry). Keep alerts actionable and production stable.
Lead incident troubleshooting, on-call response, and postmortems. Keep improving capacity planning, autoscaling, and disaster recovery.
Own cloud cost and security: remove idle resources, enforce least-privilege IAM, and manage multiple accounts and internal network access.

Infrastructure & Platform

Turn shared business logic into reusable services, middleware, and internal tools, and improve CI/CD so the team ships faster and more reliably.

QUALIFICATIONS

5+ years of backend development experience, including at least 2 years in cloud or infrastructure work.
Strong proficiency in Python or Go, with hands-on experience building large projects on frameworks such as FastAPI, Django, or Gin.
Solid knowledge of core AWS services, with production experience in architecture, operations, and cost optimization.
Experience with Docker and ECS / Kubernetes, and with IaC tools such as Terraform.
Strong MySQL / PostgreSQL schema design and performance tuning skills. Familiar with Redis, Kafka, Nginx, and other common middleware.
Strong production debugging skills, with on-call and postmortem experience. Good communicator who can own a project end to end, from design to launch.

PREFERRED QUALIFICATIONS

Backend experience with AI / LLM applications, such as model integration, agent systems, or managing LLM cost and reliability.
Experience supporting large-scale, high-traffic consumer products.
Multi-cloud (AWS + GCP), cloud migration, or account consolidation experience; familiarity with BigQuery or similar data platforms.
Knowledge of networking and security, such as VPN / zero trust and compliance.

BENEFITS

Top tier salary in the market + competitive equity
Full Health insurance

If you are excited about building at the frontier of AI, consumer social, and interactive entertainment, we would love to hear from you.

At Sekai, you will work with an AI-native team, move fast, own meaningful problems, and have the flexibility to explore new ideas from an early stage.
