About XLR8 AI

XLR8 AI helps brands win visibility on AI search engines like ChatGPT, Perplexity, Claude, and Gemini. As search shifts from traditional SEO to AI-generated answers, we're building the analytics and optimization layer for the next generation of marketing.

We were featured in a16z's Generative Engine Optimization (GEO) report and are growing 200% month-over-month. Our customers range from brands with hundreds of millions in ARR to early-stage startups. We're backed by top operators and investors in AI, marketing tech, and SaaS.

The Role

We're hiring a Senior Backend Engineer to own our Python API, Postgres data layer, and async job and LLM pipelines.

You'll own large parts of our backend: a Python service that runs brand-visibility experiments across OpenAI, Anthropic, Gemini, and xAI, then generates and scores content from the results. Experiments are one part of a platform that takes brands from measurement to action:

• Experiments and analytics: run visibility and sentiment experiments across many LLMs at once and track how results change over time

• Reporting: bring Search Console, Google Analytics, and first-touch survey data into one view

• Content: generate, optimize, and publish content built for AI search, straight to Webflow and WordPress

• Outreach: turn the sources AI models cite into listicle outreach campaigns

• Intelligence: AI-generated insights, prioritized action items, and social listening signals

The work is mostly about data and concurrency. This is not a Big Tech job: you'll ship weekly, work directly with the founders, and decide how things get built.

What You'll Do

• Design and evolve our Postgres data model and keep queries fast as data grows

• Build async APIs and services in Python

• Own background jobs that fan out work across model providers and third-party APIs

• Extend our LLM pipelines, mixing model calls with deterministic code

• Build reliable integrations with auth, billing, search, and CMS platforms

Who You Are (Must Have Requirements)

• 5+ years building production backends, with Python as your primary language

• Deep PostgreSQL experience: schema design, indexing, query tuning, and migrations

• Real async Python experience, including debugging the hard failures (blocked event loops, pool exhaustion, race conditions)

• Experience calling external APIs reliably: timeouts, retries, rate limits, and webhooks

• Self-directed and comfortable owning features end to end

Nice to Haves

• Built a multi-step pipeline or agent workflow that mixes LLM calls with plain code

• Hands-on with LLM APIs and structured outputs

• pgvector or other vector search in production

• Strong GitHub contributions or side projects you can show us

What You'll Get

• High ownership from Day 1; you'll ship weekly, not quarterly

• Direct mentorship from founders with experience in product, growth, and infrastructure

• A hand in shaping the future of AI search and marketing tech

• Remote-friendly culture with async flexibility and fast decision-making
