About the role

Key responsibilities & impact

Design and own backend systems that handle high-throughput, asynchronous workloads (generation queues, worker orchestration, media processing)
Architect for scale and reliability — you'll make the calls on data flow, service boundaries, and failure handling
Build and optimize async pipelines: job queuing, retries, backpressure, dead-letter handling, and everything that keeps millions of requests moving
Improve performance and cost at the infrastructure level — inference is expensive, and efficiency is a product feature here
Set technical direction and raise the engineering bar for the team through review and mentorship

Requirements

What you’ll need

Strong backend experience (5+ years) with real ownership of production systems at scale
Proven system design skills — you can defend your architecture decisions with tradeoffs, not buzzwords
Hands-on experience with asynchronous pipelines, message queues (Kafka, RabbitMQ, SQS, or similar), and distributed workers
Comfort with high-concurrency, high-throughput environments
Ability to work independently in a fast, low-process, bootstrapped environment
