Job summary

Figma is seeking a senior infrastructure engineer to anchor the Infrastructure & Hosting pillar of our Internal AI team. You’ll design and build the paved path for internal AI apps, bots, or agents from prototype to production, including hosting, model routing, and the cost-attribution layer.

You’ll work closely with IT Security on guardrails and identity, and with AI infra squads to share gateways and telemetry. This is a founding-team role shaping platform strategy at scale.

Qualifications

• 5+ years in software engineering with focus on infrastructure or backend.
• Proven track record building internal platforms adopted by teams.
• Strong system design skills for resilient, observable production systems.
• Hands-on experience with LLM ops, model gateways/routing, cost instrumentation.
• Experience with enterprise IAM (Okta, SSO) and secure auth practices.

Responsibilities

• Design and build the hosting golden path for internal AI applications, bots, and agents, including runtime patterns for long-running workflows, scheduled jobs, and agent execution
• Build the model routing layer that directs tasks across frontier and lower-cost models based on cost, capability, and policy with a full audit trail
• Stand up observability, usage analytics, audit logging, and per-team cost attribution for AI workloads across the company
• Integrate identity, access, and security patterns (Okta-connected by default) so every internal AI app is safe on day one, including the sanctioned path for workflows touching customer, financial, or people data
• Partner with engineers on our product AI infrastructure teams to share gateways and telemetry rather than building parallel systems
• Help shape the team's platform strategy, roadmap, and engineering best practices as a founding member of the infrastructure pillar
