Agent guide: [/agents.md](https://www.wearedevelopers.com/agents.md). --- # Backend Engineer, Core Systems - **Company:** MIDJOURNEY, INC. - **Location:** United States - **Salary:** $175,000.0 - $200,000.0 - **Contract:** Permanent contract - **Skills:** Midjourney, Application Programming Interfaces (APIs), Artificial Intelligence, Data Stores, Software Debugging, PostgreSQL, Ansible, Software Engineering, Backend, Build Tools, Slurm - **Published:** July 27, 2026 - **Apply:** https://www.indeed.com/viewjob?jk=3a264a511eed8aae ## About the Role * You're comfortable designing APIs, modeling data, and working across services rather than inside a single layer. * You think about failure modes before they happen and build systems that behave well under load. * You're comfortable owning production, including debugging, observability, and operational tooling. * You enjoy making complex systems simpler. * AI tools are part of your development workflow, and you're always looking for better ways to build software. * You communicate clearly and work well with engineers across different disciplines. * You care about the people around you as much as the code. Great engineering teams make each other better., * Experience operating Postgres or similarly load-bearing data stores at scale, including schema evolution under live traffic. * Experience with high-throughput async job systems (queues, schedulers, workers). * Background designing the seam between a product backend and an ML inference platform. * Familiarity with HPC and fleet orchestration concepts (Slurm, Ansible, multi-region operations). ## Description * Design, build, and operate the backend systems that power Midjourney. * Own meaningful parts of the platform from schema to service to deployment and production health. * Build the tooling and observability that help the team understand production systems before something breaks. * Respond to production issues and turn each one into a lasting improvement. * Simplify systems as they grow by reducing complexity and building abstractions that stand the test of time. * Partner closely with inference, infrastructure, and product engineers as the platform evolves. * Ship code that reaches production quickly., * Speed of a startup, freedom and resources of a research lab. No investors, no quarterly reporting cycle, no committees deciding the roadmap. * Tiny team, large ambitions. Decisions show up in production within days. * We move at the speed of thought. Iterate fast, isolate variables, ship. * You will own meaningful slices of a system that reaches every user, including its production health. Few backend roles anywhere offer that scope on a team this small. ## Related Videos - [Shipping Faster with Less: Render on Cloud Hosting, AI Workloads, and the Future of DevOps](https://www.wearedevelopers.com/videos/1894-shipping-faster-with-less-render-on-cloud-hosting-ai-workloads-and-the-future-of-devops) - [Developing the Backend with Stefan Lingler, CTO at Shpock](https://www.wearedevelopers.com/videos/100360-developing-the-backend-with-stefan-lingler-cto-at-shpock) - [Running Secure Life Science Research at Scale using Hybrid GPU HPC and Kubernetes 🧬](https://www.wearedevelopers.com/videos/100355-running-secure-life-science-research-at-scale-using-hybrid-gpu-hpc-and-kubernetes) - [Dev & Test in the Cloud?
