About Us


We're a fast-moving startup on a mission to build AI-powered tools that make complex work simple, faster, and more intelligent. We leverage cutting-edge large language models (LLMs) to solve real problems across industries. Our team is small, senior, and passionate about what we build-every line of code makes a visible impact.


We're looking for a Senior Backend Engineer to join us in scaling the backend infrastructure that powers our AI systems.



What You'll Do




  • Design, build, and maintain backend services and APIs using Python (FastAPI, Flask, or Django)




  • Integrate and serve LLMs (e.g., OpenAI, Anthropic, Hugging Face, or open-source models) in production




  • Collaborate with ML engineers and product teams to deliver intelligent, scalable features




  • Build and optimize data pipelines for inference, prompt processing, and model fine-tuning




  • Architect systems that balance performance, security, and maintainability




  • Own projects end-to-end-from architecture and implementation to testing and monitoring





What We're Looking For




  • 5+ years of backend software development experience




  • Strong proficiency with Python and cloud infrastructure (AWS, Google Cloud Platform, or similar)




  • Experience deploying and working with LLMs in real-world products




  • Deep understanding of RESTful APIs, asynchronous programming, and containerized services (Docker, Kubernetes)




  • Familiarity with data pipeline tools and task queues (Airflow, Celery, etc.)




  • Product mindset-you think beyond code and care about usability, performance, and impact





Bonus Skills (Not Required but Nice to Have)




  • Experience with FastAPI




  • Familiarity with vector databases (Pinecone, Weaviate, FAISS)




  • Prompt engineering or fine-tuning experience with LLMs




  • Background in NLP, search, or applied ML




  • Experience building dev tools, SaaS, or productivity platforms





Why You'll Love Working Here




  • Competitive salary ($120K-$180K) + meaningful equity




  • Fully remote, flexible work environment




  • Comprehensive health, dental, and vision insurance




  • Wellness, L&D, and home office stipends




  • Work on cutting-edge AI systems that ship to real users




  • Smart, low-ego team that values impact over bureaucracy
