The Machine team at Code and Theory operates as a bleeding edge enterprise AI startup within the larger agency. We are always striving to balance the demanding nature of working on cutting-edge technologies with the real-world demands of high performance, high security, and accessibility. Working in collaboration with our multi-disciplinary engineering, design, and quality assurance teams, you will build an AI-native software ecosystem that powers marketing workflows for both internal and external users. 

You are a passionate advocate for software quality, its role in our society, and its relationship to technology. You deeply understand nuances of how to achieve experiences which are high performance while being cutting-edge, immersive and impressive for the end user.

WHAT YOU’LL DO

• Lead the technical direction of projects, making high-level architectural decisions for full-stack applications that integrate AI services
• Design and build robust backend services (Python) and intuitive, interactive frontend interfaces (React/Vue/Angular) that visualize complex data and AI interactions
• Architect and maintain data processing pipelines, agentic workflows, and LLM integrations to solve real-world client problems
• Foster a culture of excellence by performing rigorous code reviews, mentoring junior and senior developers, and driving the adoption of best practices
• Partner closely with Product Management, Design, and QA to translate complex requirements into technical roadmaps and deliverable software
• Evaluate system performance across the full stack, identifying bottlenecks in both the frontend rendering and backend AI inference layers to ensure scalability and reliability
• Stay ahead of the curve on the latest AI trends (e.g., SLMs, Agentic AI, Multimodal models) and web technologies, advising stakeholders on feasibility and implementation

WHAT YOU’LL NEED

• 7+ years of total software development experience, with at least 2+ years in a leadership or lead developer capacity
• Expert proficiency in Python for backend development (FastAPI, Flask, or Django) and data processing
• Strong experience with modern JavaScript/TypeScript frameworks (React, Vue, or Angular) and state management
• Proven experience building applications on top of LLMs (OpenAI, Anthropic, OSS models), implementing RAG patterns, and using frameworks like LangChain or LlamaIndex
• Deep experience designing and consuming RESTful APIs, GraphQL, and WebSockets
• Mastery of Git, CI/CD pipelines, containerization (Docker/Kubernetes), and automated testing frameworks (Pytest, Jest, Cypress)
• Experience with both relational databases (PostgreSQL) and Vector databases (Pinecone, Milvus, Weaviate, or pgvector)
• Strong communication skills with the ability to explain complex technical concepts to non-technical stakeholders

NICE TO HAVE

• Experience with Next.js and deploying to platforms like Vercel or AWS Amplify
• Familiarity with Data Visualization libraries (D3.js, Three.js, or Highcharts) for rendering complex AI data
• Experience fine-tuning LLMs or working with open-source models (Hugging Face)
• Cloud certification (AWS, Azure, or GCP)
• Expert understanding of web accessibility (WCAG) and animation performance
