Lead Infrastructure & Platform Engineer

About the role

This is a high-ownership role. You'll be the person the rest of engineering depends on to ship, and you'll set the patterns for how we deploy, secure, and operate. You'll also lead the next chapter: we're building out our own GPU infrastructure inside a colocation facility, which means real networking, capacity planning, and bare-metal platform work sitting alongside our cloud footprint. If you want a surface where the decisions are yours and the impact reaches millions of learners, this is it.

Responsibilities

• The platform, end to end. Our infrastructure-as-code (Pulumi/TypeScript on GCP), the Kubernetes clusters, the Shared VPC and networking, the CI/CD and deploy tooling, secrets, and the databases behind them. You own how the whole thing fits together and how the team ships on top of it.
• Reliability and the on-call that follows. Monitoring, alerting, incident response, and the postmortems that make the next incident less likely. When production has a bad night, you're the person who understands why and makes sure it doesn't repeat.
• Our own GPU infrastructure, from the ground up. We're standing up GPU capacity in a colocation facility. You'll help design and build it: hardware and capacity planning, physical and virtual networking, the platform layer that makes those GPUs usable for model serving, and the path that connects it cleanly to our cloud environment. This is a meaningful part of the role, and it's new ground for the company.
• The GPU serving platform. The clusters and pipelines that run our self-hosted models and speech/ASR workloads, keeping latency, cost, and utilization where they need to be for real users at scale.
• Security and compliance posture. We hold ourselves to a real bar (SOC 2, continuous scanning, least-privilege IAM). You keep the platform audit-ready without slowing the team down.
• The bar for the team. The patterns you set for how we deploy, secure, and operate are the ones everyone else follows. As the work grows, you'll shape and help grow the team that does it with you.

Requirements

You're a strong fit if either of these is true:

• 7+ years building and operating production infrastructure, with real depth in cloud platform, Kubernetes, and networking, or
• You were the founding or early infrastructure engineer who owned a significant share of a real platform. Fewer years on paper, but you took production infrastructure from early and messy to reliable and are able to demonstrate it.

Beyond that:

• You've run production infrastructure that real users depend on, not lab setups. You can walk us through a platform you built or operated, which parts were yours, an incident that went badly, and what you changed because of it.
• You have hands-on experience with physical or colocation infrastructure. Bare-metal provisioning, datacenter or colo networking, hardware and capacity planning, GPU fleets, or standing up a hybrid of on-prem and cloud. This is the newest part of the role, and experience here is a real differentiator.
• You're fluent in modern cloud and Kubernetes. Infrastructure-as-code is how you work, not a thing you tolerate. You have opinions about ownership boundaries, blast radius, and what belongs where.
• You use AI every day and have informed opinions about it. You understand the demands of serving models in production, and genuine curiosity is the one thing we can't teach.
• You've worked through launch crunch and know how you stay effective and level-headed under pressure.
• You're candid about tradeoffs. You can tell us what surprised you last time and what you'd do differently.
• The mission is why you're here. What sustains you through the hard weeks is the learner on the other end, the one who finally understands because of something you kept running.

Qualifications

• You don't need every item below, but you should be deep in most and able to ramp quickly on the rest:
• Cloud & platform: GCP, Cloudflare, Vercel; infrastructure-as-code (Pulumi or Terraform)
• Orchestration: Kubernetes (GKE), Helm, container build pipelines, CI/CD (Jenkins or similar)
• Networking: VPC design, IPAM, firewalls, DNS/TLS, zero-trust access, and — for the colo work — physical and datacenter networking
• GPU & AI serving: GPU cluster operations, model/inference serving, vLLM, ASR/speech workloads, cost and latency tuning
• Hardware / colocation: bare-metal provisioning, capacity planning, hybrid on-prem + cloud
• Data: PostgreSQL and MongoDB, managed caches (Redis/Valkey), backups and disaster recovery
• Observability & security: monitoring and alerting, incident response, least-privilege IAM, secrets management, SOC 2-grade compliance

Skills

• Strong technical skills in cloud platforms, Kubernetes, and networking
• Experience with GPU infrastructure and AI serving
• Hands-on experience with physical or colocation infrastructure
• Fluency in modern cloud and Kubernetes
• Informed opinions about AI and its practical applications
• Experience working through launch crunch and maintaining focus under pressure
• Candidness about trade-offs and past experiences

Benefits

We offer:

• $170,000–$270,000 base salary, plus equity
• 100% employer-paid Medical, Dental, and Vision; 75% dependent coverage
• 401(k) with employer matching
• Daily team dinner provided in-office
