Fresh off an $8M seed round from top-tier investors, they're looking for a hands-on AI Platform Engineer to design and build the backbone of their platform - infrastructure that enables one person to deliver the output of thousands. In this role, you'll work side-by-side with the founding team to ship production systems at speed. You'll evolve their proprietary context engineering platform, develop evaluation frameworks, architect ML models, and build growth-focused AI tools. This is a role for someone who thrives in high-intensity environments, takes ownership, and measures success by shipped product, not planning decks. Key responsibilities: Enhance their in-house AI Grid platform combining ETL pipelines with LLM orchestration Build evaluation systems using human-annotated datasets for model fine-tuning (SFT/RL) Develop ML models for reasoning engines, load balancing, and market-making systems Architect robust data pipelines feeding multiple destinations (vector DBs, ML platforms, analytics systems) Implement MCP servers to connect agents with tools and persistent memory Create voice AI systems for outbound, follow-up, and customer service use cases Integrate payment providers and financial systems directly into the platform Work closely with forward deployed engineers to ensure business impact You'll be a great fit if you have: Strong background in distributed systems, AI agents, and modern data engineering Proven experience in both TypeScript/Node.js and Python Track record building production ML infrastructure, ETL/ELT workflows, and orchestration systems Experience with MCP protocols, vector DBs, and retrieval-augmented generation Familiarity with voice AI architecture, payment integrations, and real-time processing systems A bias toward action - you ship fast, iterate, and improve continuously Tech stack: TypeScript, Node.js, Python, Next.js, Databricks, Astronomer, Temporal.io, Pydantic-AI, Redis Streams, PostgreSQL, ClickHouse, Apache Airflow, vector DBs, Claude, GPT-4, and more. Why join: This is a rare chance to be early in a well-funded, high-growth AI startup where your work directly shapes the company's technical foundation. The role is based in San Francisco, with relocation assistance provided, and requires working in-office 5.5 days a week alongside an exceptional founding team. If you're an engineer who thrives on building AI systems that change industries, we'd like to hear from you.

About You: You will be working on our backend built with Python/FastAPI (with lots of asyncio), Postgres, and Redis. You should be immediately productive coming into a codebase on this stack. You understand how to build resilient applications with LLMs: managing tool calls, prompts, cost/latency tradeoffs, etc. You have clear likes and dislikes about AI coding tools you have tried, and know what should be better. We dogfood a lot and at the end of the day, we're building for software engineers like ourselves. About Us: Indent is building the platform that every software engineer begins and ends their day in. Our customers are large engineering teams who use Indent for everything from incident response to code review to data analysis. Indent is built to handle these tasks in the real world (think analyzing a 30,000 table warehouse, not vibe querying a tiny Postgres instance) with minimal setup. We are a small, engineering-focused team. We come from a background of systems and infrastructure engineering, working on things like the Swift Compiler, distributed data orchestration software, and scaled video conferencing systems. We think that rigor is an advantage in this get-rich-quick market. We are taking an ambitious approach to a massive market. At Indent, one engineer can own a product like the Incident Response Agent that outperforms entire companies solving the same problem.
