foam — Founding Engineer Type : Full-time | On-site | San Francisco, CA Compensation : $250,000–$400,000 + 0.25%–2% equity Hiring count : 1 Visa sponsorship : H-1B transfers, TN (Canada and Mexico), OPT to H-1B, H-1B1 Singapore, E-3 Australia Reports to : Founders (no named hiring manager / LinkedIn provided) About foam foam finds and diagnoses errors, incidents, and degradations in production before users do. When something breaks, foam cuts through the noise, identifies the single root cause, and pings the responsible engineer with a fix ready to go — no prompting required. It is positioned as the first telemetry and production system designed for LLMs, giving them full visibility into and control over running software, starting with automatic error fixes. Published benchmark: 86% root-cause accuracy, beating Cursor + MCP setups by 20+ points. Founded: 2024 | Team size: 1–10 (Seed) | Total funding: $10M (Khosla Ventures, Max Levchin, The House Fund, South Park Commons) | Industry: AI Tools / Dev Tools | Website: foam.ai | Office: San Francisco, CA | Customers: Perplexity, GPTZero, Together AI, Braintrust, Orb | Team backgrounds: xAI, Affim, Berkeley EECS, OpenAI Why Candidates Should Join Founding-level ownership: Real influence over system design, architecture, and product direction from day one, across full-stack, infra, and support as the company grows. Genuinely hard AI problems: Building multi-agent reasoning systems on real telemetry to produce correct root-cause analyses — not pipelines or fine-tuning. High-signal team and backing: $10M seed, top-tier investors, and a founding team out of xAI, Affim, Berkeley EECS, and OpenAI, with live customers already onboard. The Role foam is hiring a Founding Engineer to build the systems that deliver accurate root-cause analysis to clients. The role is not limited to full‑stack, infra, or support — as the company grows, the engineer will be pulled across all of these problem areas. What You'll Be Doing Building multi‑agent reasoning systems that use real telemetry to produce correct root cause analyses. Getting handed problems no one has ever seen and coming up with solutions, like automating error analysis. Setting up telemetry pipelines, improving tooling and SDKs, and building systems that reconstruct timelines across logs, traces, and deploys. Building automatic instrumentation that tracks code behavior, preserves async context, and improves visibility into backend operations. Helping build not just the systems that deliver correct RCA, but the systems that build those systems.
