Platform Integrations Engineer, AI Systems

**About T4R Labs** T4R Labs is a deep tech lab building at the frontier of AI. We work on hard, unsolved problems where real-time performance, multi-modal understanding, and safety all have to hold up under production load — not just in a demo. **The Role** We're looking for a platform integrations engineer to own the connective tissue between our realtime, multi-modal AI systems and the outside world — partner APIs, third-party platforms, and internal services. You'll be the person who makes sure data and events flow reliably across systems that don't always play nice together, often in realtime. This is a hands-on role on a small team, where you'll have real ownership over which integrations get built and how. **What You'll Do** * Design, build, and maintain integrations between our AI systems and third-party APIs and platforms * Work directly with partner and vendor APIs — handling auth, rate limits, versioning, and failure modes gracefully * Build the connective tissue that lets our AI systems reliably talk to the outside world in realtime * Debug integration issues quickly, often with limited or inconsistent documentation on the other side * Collaborate with the core engineering team to prioritize which integrations matter most and design them to last **What We're Looking For** * 3–5 years of experience building and maintaining integrations * Fluency working with a wide range of APIs (REST, GraphQL, webhooks, streaming) * Experience doing integrations for AI systems specifically — connecting models, agents, or AI platforms to other systems * Comfort dealing with ambiguous or under-documented third-party systems * Curious, entrepreneurial, and comfortable speaking your mind — we want people who'll push back on a bad idea, ours included * A self-starter who takes real ownership and accountability, but also works well as part of a small, close-knit team **Bonus points for:** * Experience integrating AI/LLM APIs (OpenAI, Anthropic, or similar) into production systems * Experience with realtime or streaming APIs (WebRTC, websockets) * Background in security preferred **Why T4R Labs** * Work directly with the founding team on problems that don't have off-the-shelf solutions * High autonomy, high impact — your decisions ship * We're seed stage: this role is equity only for now, with salary starting once we close funding **Work Authorization & Background Check** You must be a U.S. citizen or otherwise authorized to work in the United States without employer sponsorship. As an early-stage company, we're not able to sponsor work visas at this time. Final offers of employment are contingent on successful completion of a background check. **How to Apply** Reach out with your resume and a note on the trickiest integration you've had to build.
