Job description:

**Location:** In-person, SF or Remote\ \ **Requirement:** Pursuing Bachelors in Computer Science from Top US Unverisity (Stanford, Berkeley, MIT, GeorgiaTech, etc.) **Stack:** Python, FastAPI, PostgreSQL, AWS (ECS, Fargate), Qdrant, TypeScript **What You’ll Work On** **Backend Infrastructure:** * Building and scaling services in **Python** (FastAPI) with **PostgreSQL** as our primary database. * Managing AWS infrastructure — primarily **ECS/Fargate**, Lambda, S3, and related services. * Designing APIs for our frontend (TypeScript) and partner integrations. **AI/ML Engineering:** * Building agentic workflows and pipelines for large-scale **LLM calls** (OpenAI, Gemini, Perplexity). * Designing and maintaining **RAG** (Retrieval-Augmented Generation) systems using **Qdrant** for vector search. * Optimizing prompt engineering, retrieval strategies, and evaluation systems. **The ROLE** You are **not** just an employee – you are a builder of the company. You’ll be at the core of shaping Relixir’s product, technology, and trajectory – from hands-on backend and AI engineering, to collaborating on the big decisions that define our future. * **Strategic Impact** – Work directly with the founders to influence technical and product direction, deciding how we scale our platform and what bets we make in AI search automation. * **End-to-End Ownership** – Take ideas from rough concept to production-ready systems – APIs, infrastructure, AI agents, and everything in between. You’ll own critical backend modules and ensure they’re fast, reliable, and a joy to use. * **AI Systems Engineering** – Design and deploy large-scale AI workflows – multi-agent pipelines, RAG architectures with Qdrant, and high-volume LLM call orchestration. * **Customer-Driven Development** – Talk to customers, dig into their needs, and turn feedback into technical solutions that directly impact their growth. ## **About You** * **Deeply Curious** — You actively seek to understand complex systems, customer problems, and the latest technical possibilities. Curiosity drives your best work. * **Relentlessly Driven** — You thrive in early-stage chaos. You move quickly, test bold ideas, and turn uncertainty into working solutions. * **True Owner** — You don’t just “complete tickets.” You take full responsibility for delivering outcomes — finding a path forward even with incomplete information. * **Collaborative & Humble** — You share ideas openly, listen actively, and care more about the best solution than being right. You’re confident in your skills but always learning. **Must-Haves** * In-person SF * High-agency * Experience building backend & AI software for VC-backed startups * Strong proficiency in Python and TypeScript * Experience with Docker, FastAPI, PostgreSQL, and AWS * Built and deployed a complex agentic/LLM-backed (context engineering, RAG with vector db) into production to customers * Have completed at least one 0 -> 1 journey of a functional product **Nice-to-haves:** * Experience working with any of AWS ECS + SQS + Fargate, QDrant, LangChain * Entrepreneurial Mindset: Ex-founder or future founder --- ### **Why This Role is Special** We're growing 166% MoM, onboarding monster logos (Rippling, Airwallex, Hackerrank, etc.), supporting global marketing teams, and on our way to Series A by EOY.\ \ This August, I'm looking for the most cracked top 1% founding engineers and founding customer success/ops to join our rocketship 🚀\ \ \ Here's my pitch to you: 1. Our product is far ahead of the competition. Companies are switching to us every week because they see the differentiation & immediate value. 2. Revenue pipeline is already at $X,000,000 <2 months since launch and rapidly growing. There's simply more customers than we can handle. 3. Customers now see Relixir as the unified solution to automate their entire SEO/GEO Growth Marketing function: a $400B market opportunity. 4. We're backed by Y Combinator and legendary operating investors like [**z21 Ventures**](https://www.linkedin.com/company/z21-ventures/) who have built unicorns from scratch.\ \ \ Lastly, our team is a group of nonchalant, hardworking, super chill college dropouts from Berkeley who have scaled and even exited previous companies for 7-figures.
