About Marseer AI

Marseer AI (www.marseerai.com) is a Seattle-based company building an AI-powered marketing intelligence platform for DTC and retail e-commerce brands. The platform combines brand strategy, customer data, automation, and generative AI to help marketing teams drive consistent, data-driven engagement across email, SMS, paid media, SEO, and affiliate channels.

Role Overview

We are looking for an experienced AI Engineer - Full Stack Developer to join the Marseer platform team. This is a dual-track role: you will build and maintain AI agent pipelines, LLM integrations, and RAG-based intelligence systems on the backend, while also owning frontend interfaces that surface insights, recommendations, and campaign outputs to marketing teams and brand operators.

You should be equally comfortable designing multi-step agentic workflows in Python and building clean, responsive product interfaces in React/Next.js. You understand how LLMs behave in production, know how to engineer prompts and tool chains for reliability, and care deeply about the end-to-end user experience.

What You Will Do

- Design and implement multi-step AI agent workflows using LLM orchestration frameworks such as LangChain, LangGraph, CrewAI, or similar.

- Build and maintain RAG pipelines, including chunking strategies, embedding generation, vector store management, and retrieval tuning.

- Integrate with LLM providers such as OpenAI, Anthropic, or others, including prompt engineering, tool/function calling, structured output generation, and context window management.

- Develop AI-driven features such as campaign brief generation, audience recommendations, content variant creation, and performance insight summarization.

- Implement evaluation and observability frameworks to monitor LLM output quality, latency, and cost in production.

- Build frontend interfaces using React and Next.js, including dashboards, agent interaction UIs, campaign builders, and insight surfaces.

- Design and implement RESTful and/or GraphQL APIs in Python (FastAPI or Flask) or Node.js to serve AI outputs to the frontend.

- Integrate frontend with backend AI services, streaming LLM responses, and real-time status updates.

- Work with structured and unstructured marketing data, campaign performance metrics, audience segments, content libraries, and brand strategy documents.

- Integrate with marketing platforms and data sources such as Klaviyo, Google Ads, Meta, and Shopify.

Requirements

- 5-10 years of professional software engineering experience, with meaningful time in both backend and frontend development.

- Proven experience building and deploying LLM-powered applications in production, not just prototypes.

- Strong proficiency in Python for backend and AI development.

- Strong proficiency in React and Next.js for frontend development.

- Hands-on experience with LLM orchestration frameworks such as LangChain, LangGraph, CrewAI, or equivalent.

- Experience building RAG pipelines, vector stores such as Pinecone, Weaviate, pgvector, or similar, embedding models, and retrieval strategies.

- Experience with API design, REST or GraphQL, and backend service architecture.

Strongly Preferred

- Experience designing and building multi-agent or agentic AI systems with tool use, memory, and planning capabilities.

- Familiarity with prompt engineering best practices, structured output generation, and LLM evaluation methodologies.

- Experience with streaming LLM responses and real-time UI updates using SSE or WebSockets.

- Prior work in a SaaS product company shipping production features.

- Familiarity with marketing platforms, e-commerce data, or martech ecosystems.

Good to Have

- TypeScript and modern frontend tooling such as Tailwind CSS or shadcn/ui.

- Familiarity with Snowflake or other cloud data warehouses as data sources for AI pipelines.

- Experience with observability tools for LLM applications such as LangSmith, Helicone, Arize, or similar.

- Understanding of marketing concepts such as segmentation, campaign lifecycle, attribution, and content personalization.

What We Are Looking For

- Availability to work US business hours; overlap with US Eastern or Pacific timezone is required for client collaboration and team standups.

- Strong written and verbal English communication.

- Product sense and ownership mindset.

- Comfort with ambiguity in non-deterministic LLM-powered systems.

- Collaborative working style across engineering, design, and client-facing functions.

What We Offer

- Competitive compensation based on experience.

- Fully remote role; work from anywhere in India, with Hyderabad-based candidates preferred.

- High-impact work at the frontier of applied AI for marketing and e-commerce.

- Direct exposure to real brand problems, real data, and real production AI systems.

- A small, senior team where your architecture decisions matter and your contributions are visible.

🚀 AI Marketing Automation Developer Intern

AI-First | High Ownership | Long-Term Opportunity

📍 About the Role

We are building an AI-first marketing and communications engine across multiple products and brands.

This role is for someone who wants to use AI to eliminate manual work, not do more of it.

This is not a traditional marketing internship.

It is a builder role focused on automation, experimentation, and systems thinking.

🧠 How We Work

• AI-first, automation-first mindset
• We focus on outcomes, not activity
• You will work independently on clearly defined objectives
• Minimal meetings, maximum ownership
• Trial, iterate, break, fix, and improve
• What you build is expected to be production-ready, not just a demo

We use modern AI tools (including Cursor and LLMs) and expect you to learn fast and apply faster.

✅ Who This Is For

This role is a strong fit if you:

• Think in terms of systems and leverage
• Enjoy solving open-ended problems
• Are comfortable with ambiguity
• Like experimenting until something works
• Want to work in a real AI-first environment, not just talk about AI

Background matters less than mindset.

Engineering, tech-savvy marketing, or self-taught AI backgrounds all work.

❌ Who This Is NOT For

• Manual or repetitive marketing work
• Copy-paste or template-only roles
• People who need detailed step-by-step instructions

🌱 Growth & Long-Term Path

This is a long-term internship, not a short project.

Interns who:

• Consistently deliver
• Show ownership
• Fit into our AI-first work culture

👉 Will be converted to full-time roles.

Hiring and conversion decisions are made jointly by the founders and the automation team lead.

🕒 Commitment

• 20–30 hours per week minimum
• Fully remote
• Flexible working hours (output > hours)

A short note on why this role excites you

• Track record of delivering various features in large-scale applications or core systems with at least 5 years of experience. If you've written code in big data applications handling multitudes of data or real-time events, you're in.
• Experience writing multi-component systems or micro-services, with architectures requiring efficient inter-application communication. If you know what Kafka is, and think it's the bee's knees, we will think the same of you.
• Experience writing in a high-level language such as Go, C, Rust, Python, Ruby, etc.. If you're already writing Go, or spent a weekend debugging the worse memory leak ever, that's a big plus.
• Experience writing APIs (either RESTful or not) and RPCs. If you've broken backwards compatibility for your customers once, and dealt with the fallout, we want you (to deal with the fallout again).
• Experience with RDBMS systems (e.g. MySQL, PostgreSQL, Oracle, SQLite) and/or NoSQL databases (e.g. MongoDB, Redis, Cassandra, Couchbase). If you've written queries with more than two joins, or have a strong opinion of why an integer is better as a primary key (or maybe a UUID), we'd like to hear from you.
• Experience with container platforms and orchestrators such as Docker, Kubernetes and OpenShift is a plus. If you can name one way in which a container is different than a regular process, you're golden.
• Are you a free software/open source nerd? Do you maintain open source projects? Are you a Hacker News reader? Do you remember the days when you had to compile your own Linux kernel? Do you believe it should be called GNU/Linux? Have you ever been in a fight with an Emacs user? Are you an Emacs user? Well, we have the job for you!
