> Own and scale Go backend systems orchestrating high-volume, multimodal AI generation workloads, with responsibility for concurrency, reliability, latency, and observability. Requires extensive Go, distributed systems, AWS, asynchronous processing, and production SaaS experience.

## Job Description

## Responsibilities
- Design and scale Go microservices managing the full lifecycle of AI generation.
- Optimize ConnectRPC services and asynchronous Kafka and SQS pipelines for long-running, resource-intensive inference.
- Build backend orchestration across image, video, audio, 3D, and vector generation.
- Use AWS to manage high data throughput and integrate with high-performance storage and compute clusters.
- Collaborate with external providers and Product to turn model output into production user experiences.
- Document architectural decisions involving concurrency, queueing, backpressure, and failure handling.
- Improve reliability and latency across the generation path and own observability.
- Own code review, testing strategy, and on-call readiness.
- Integrate new generative models into production workflows.
- Contribute to backend platform technical direction and stay current with distributed systems, AI infrastructure, and model serving.

## Requirements
- Extensive experience building and scaling backend services in Go for high-traffic, high-volume SaaS environments.
- Experience designing distributed microservice architectures with asynchronous processing, low-latency service communication, queueing, backpressure, retry strategies, and resource-intensive workloads.
- Deep AWS knowledge, including EKS, S3, and Lambda.
- Solid relational database skills, preferably PostgreSQL, including schema design, query performance, and scaling.
- Production experience with observability, performance profiling, live-system debugging, code review, and automated testing.
- Ability to own and document architectural decisions.
- Strong written and spoken English communication skills.
- Self-directed approach, sound engineering judgment, and ownership of system reliability and quality.
- Ability to work effectively in a distributed team with limited real-time overlap.

## Nice to Have
- Media processing experience, such as video transcoding, audio synthesis, or vector manipulation.
- AI infrastructure experience, including model serving at scale, GPU-accelerated workloads, integrating generative models, and compute-cost optimization.
- Startup or fast-moving distributed-environment experience.
