Senior Backend Engineer

Senior Backend Engineer / Architect
ImagineArt · Onsite · NSTP, Islamabad

About the role

We're a bootstrapped GenAI platform serving image and video generation at real scale — Fortune 500 clients, $35M+ ARR, and traffic that doesn't wait for you to catch up. We need a backend engineer who thinks in systems, not just services. You'll own the architecture behind our generation pipelines, inference orchestration, and the infrastructure that keeps latency low while volume climbs.

This is a hands-on architect role. You will design and write code, not just draw diagrams.

What you'll do

• 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 feat
