Senior Backend Engineer (Go), LLM and RAG in production, AI product

Зарплата: $4500–$6500

We are New Wave Devs, a senior engineering team. We are hiring a Senior Go engineer to embed long-term with our client, a Netherlands-based AI-native creative-tools company building the backend of their AI Studio product.

It is a fast-paced product team: new frontier AI models are pushed into production within a day or two of release. You will own real pieces of the backend and work directly with their engineers.

What you will do:
Design and scale Go microservices that manage the lifecycle of AI generations (image, video, audio, 3D, vector)
Build and run RAG pipelines and agent orchestration around production models
Handle long-running, resource-intensive inference tasks and high data throughput: queues, backpressure, retries
Work with AWS (EKS, S3, Lambda), Kafka and SQS for async processing, ConnectRPC / gRPC / GraphQL
Bridge AI model outputs into user-facing creative workflows

You should have:
5+ years backend, Go-first
Hands-on LLM or RAG work that reached production, not API calls from a prototype: LangChain, LangGraph, pgvector or similar
AWS (EKS/K8s), Kafka or SQS, gRPC/ConnectRPC, microservices at scale
Ownership mindset, comfortable when specs are not perfect, able to switch between shipping fast and building for scale
Real interest in the product itself. The client asks about it directly.
Good English, daily work with the client team

We offer: long-term full-time contract through New Wave Devs, competitive rate, fully remote, fast start, days not weeks. Two technical interviews with the client's engineers, screen share and real code.
