Agent guide: [/agents.md](https://www.wearedevelopers.com/agents.md). --- # Software Engineer, Backend - **Company:** KREA LLC - **Location:** San Francisco, CA, United States - **Experience:** Experienced - **Contract:** Permanent contract - **Skills:** Application Programming Interfaces (APIs), Python (Programming Language), PostgreSQL, Redis, Openapi, State Machines, Backend, Data Layers, Kubernetes, Vertica - **Published:** August 4, 2026 - **Apply:** https://www.indeed.com/viewjob?jk=f6cf1d454b76727b ## About the Role We care more about first-principles engineering than which languages or tools you happen to know * You've owned real production systems end-to-end: design, monitoring, metrics, incidents. Ideally you have 4-8 years of experience, but we care about scope and judgment over the number on your resume * You're comfortable across the stack and unfazed by unfamiliar code, and you have opinions about how to architect things that scale * You write and talk clearly, and you're happy working without a lot of PM hand-holding Bonus if you: have GPU or infra experience, have run Kubernetes in production, or come from a creative background. A lot of us do, and it helps when you're building tools for creatives (but it's genuinely not a requirement). ## Description You'll work across the whole backend: the SvelteKit app and its Postgres, Redis, and ClickHouse data layer, the Python services that run our ML inference, and the Kubernetes clusters that tie it together across multiple cloud and GPU providers. You'll own these systems end-to-end, from design through to running them in production., * Durable execution for long-running workflows. Building the state machines, idempotency, and retry semantics that keep multi-step inference jobs correct when they take minutes to finish and anything can fail mid-flight * Improving our public API. Designing a clean, well-documented API surface with OpenAPI docs auto-generated from our Zod schemas * Enterprise product features. ACLs, audit logs, entitlements, and all the "boring" features that organizations with a thousand users expect ## Related Videos - [Reducing LLM Calls with Vector Search Patterns - Raphael De Lio (Redis)](https://www.wearedevelopers.com/videos/1714-reducing-llm-calls-with-vector-search-patterns-raphael-de-lio-redis) - [For the REST of us: API First and Conway’s Law](https://www.wearedevelopers.com/videos/1932-for-the-rest-of-us-api-first-and-conway-s-law) - [Developing the Backend with Stefan Lingler, CTO at Shpock](https://www.wearedevelopers.com/videos/100360-developing-the-backend-with-stefan-lingler-cto-at-shpock) - [Inside Bitpanda's Tech Stack: Scaling a European Fintech Leader - Markus Dorner](https://www.wearedevelopers.com/videos/1979-inside-bitpanda-s-tech-stack-scaling-a-european-fintech-leader-markus-dorner) - [Meet Your New BFF: Backend to Frontend without the Duct Tape](https://www.wearedevelopers.com/videos/682-meet-your-new-bff-backend-to-frontend-without-the-duct-tape) - [Contract-First Frontend: Scaling Reliable UIs with OpenAPI and AI](https://www.wearedevelopers.com/videos/1995-contract-first-frontend-scaling-reliable-uis-with-openapi-and-ai) ## Related Articles - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers) - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline) - [Navigating the AI Shift](https://www.wearedevelopers.com/magazine/629-navigating-the-ai-shift) - [The Best X (Twitter) Accounts for Developers](https://www.wearedevelopers.com/magazine/294-the-best-x-twitter-accounts-for-developers)
