Founding Engineer - Platform

Role Description

You'll design and own the scalable, low-latency infrastructure that powers uRun's real-time inference runtime, the platform that makes live, interactive, multi-user AI workloads possible.

• This is not classic ops or cloud management; you'll be deep in the AI runtime itself.
• Latency, frame rate, and interactive quality of service are first-class platform properties.
• The workloads are GPU-constrained, memory-bound, and bursty.
• You will often write platform features, custom controllers, and scaling logic.
• You will report directly to our founder, Keegan McCallum, and set the technical direction for the engineering organization.

Qualifications

• 7+ years as an engineer, with a proven track record architecting and owning large-scale production systems.
• Deep Kubernetes expertise, including GPU-heavy clusters (NVIDIA tooling, autoscaling on GPU nodes) and service-mesh patterns.
• Strong cloud and infrastructure-as-code experience: AWS, GCP, or Azure; Terraform, Pulumi, or equivalent; networking and security (VPC, IAM, API-gateway-style routing).
• SRE-style thinking and observability depth: Prometheus/Grafana, OpenTelemetry, distributed tracing, SLOs, incident response, and post-mortems.
• Proficiency in at least one of Python, Go, or TypeScript/Node.js for platform tooling, automation, and glue code.
• Experience with streaming or real-time systems: WebRTC, low-latency video pipelines, or comparable latency-sensitive workloads.
• A track record of mentoring engineers and influencing cross-functional teams.

Requirements

• Hands-on experience with GPU-constrained, memory-bound, or bursty workloads.
• Experience writing custom Kubernetes controllers, scaling logic, or other platform features in-house.
• Early-stage startup experience: owning ambiguous problems end-to-end and setting technical direction with limited scaffolding.

Benefits

• Competitive salary and meaningful equity in an early-stage AI infrastructure company.
• Health, dental, and vision — full coverage.
• 401(k) — company-supported retirement savings.
• FSA/HSA — flexible spending accounts for healthcare costs.
• Paid time off — we trust you to manage your time.
• Top-tier tooling — access to the best AI tools available: Claude, Codex, Kimi, and whatever else helps you move faster.
• MacBook Pro and AirPods — the hardware you need, on us.

Company Description

We build the stage, not the show. We're an infrastructure company, a developer-tools company, and a production partner for model labs, and focus is a deliberate choice we've made and hold to.

• Day-to-day, that means a small team, a high bar, and real ownership.
• You won't wait for permission or inherit a backlog of someone else's decisions.
• In a founding security role, the function is what you make it.
• It also means ambiguity: priorities shift, not everything is documented.
• You'll often be the person who decides what "secure enough, for now" means.
