The Pitch

Slate’s product already uses AI across the stack — background removal, active speaker detection, auto-captioning, content suggestions, and image generation — but each of these is its own independent integration. We need a Senior Backend Engineer focused on AI to bring this together: unifying how we integrate models, building the infrastructure that makes AI features reliable at scale, and helping us move faster on the next wave of AI-powered capabilities.

What You’ll Actually Do

Build the AI platform layer

  • Design and build the shared infrastructure for AI integrations across Slate’s backend: model routing, prompt management, response caching, fallback handling, and cost observability

  • Refactor existing one-off AI integrations (background removal, captioning, etc.) onto a unified platform

  • Own the reliability, performance, and cost-efficiency of Slate’s AI systems

Enable new AI features

  • Work closely with the AI Product Engineer and product team to bring new AI capabilities to production

  • Build the backend systems that power real-time AI features — handling streaming, async processing, and latency constraints

  • Evaluate and integrate new models and APIs as they become available

Raise the quality bar

  • Define evaluation frameworks and monitoring to track AI feature quality over time

  • Build systems to detect and alert on model regressions or degraded outputs

  • Ensure AI features meet the same reliability bar as the rest of Slate’s infrastructure

You’d Be a Great Fit If

You have the experience:

  • 5+ years of backend engineering experience, with a track record of shipping production systems

  • Hands-on experience integrating and operating LLMs or ML models at scale

  • Strong systems thinking — you design for reliability, observability, and cost from the start

You’ve done work like this before:

  • Built shared AI infrastructure used by multiple teams or features

  • Designed async processing pipelines for ML workloads

  • Worked with OpenAI, Anthropic, Replicate, or similar APIs in production

You work the way we work:

  • You own the outcomes, not just the tasks

  • You communicate clearly and raise issues early

  • You use AI tools in your own workflow and think about how to apply them to hard engineering problems

Tech Stack

Node.js, TypeScript, PostgreSQL, Redis, AWS, OpenAI / Anthropic APIs, Replicate
