Sr/Staff Infrastructure Engineer - Perm - Relocate to SF

This is an onsite role based in San Francisco, California. International candidates are welcome to apply, with visa sponsorship and relocation support available.

About the company

A Series B legal AI company that helps in-house legal teams at Fortune 500 companies review contracts and pull insight from them. It raised $55M in 2026, revenue has grown 6x in the past year, and the team is tripling. You’d be joining at the point where the infrastructure has to scale with the business.

The role

You’ll own the platform the whole company runs on. That covers how clusters are built and operated, how code reaches production, how customer data stays secure, and how the team knows the system is healthy. This is a build role, not maintenance, and you’ll work day to day with product engineers. If you’re curious about how LLM workloads change infrastructure design, you’ll have plenty of room to experiment.

What you’ll do

• Design and operate Kubernetes across multiple clusters, regions and clouds (AWS, GCP, Azure), with failover and disaster recovery that hold up in a real outage
• Build internal tooling so creating and managing environments is consistent from a laptop to production
• Set up separate runtime strategies for ML and API workloads, balancing cost, performance and reliability without over-engineering
• Build in security that customers trust and engineers barely notice: access control, workload identity, secrets, data residency and audit logging
• Define SLOs and SLIs the team can actually hold to, with alerting that only fires when something truly needs attention
• Own CI/CD on GitHub Actions and infrastructure as code in Pulumi
• Keep Docker environments consistent across dev, staging and production
• Find hard bugs anywhere in the stack, frontend and backend included, not just in the infrastructure
• Speed up engineering: faster builds, cleaner environments, and automation for anything done more than twice
• Own observability and uptime
• Lead incident response and write postmortems the team learns from

What you bring

• 5+ years in infrastructure, platform, SRE or DevOps engineering
• Deep Kubernetes knowledge beyond deploying workloads: how clusters behave, fail and recover
• Production experience with infrastructure as code (Pulumi or Terraform), Docker and GitHub Actions in multi-cluster, multi-region setups
• A failure-first mindset: you design for what happens after something breaks
• An understanding of how compliance, legal and customer contract requirements become engineering constraints
• Enough full-stack range to debug across the stack, and the persistence to go several layers deep for the real root cause

You’ll do well here if you

• Care more about impact than about elegant solutions, and reach for the pragmatic 80/20 answer
• Are resourceful and act with urgency
• Enjoy early-stage building (startup experience is a plus, not a requirement)

Compensation and benefits

• Competitive salary plus meaningful equity $250K-$485K
• Relocation assistance to San Francisco, plus visa and green card support
• Medical, dental and vision insurance; HSA/FSA; life insurance; 401(k)
• Unlimited PTO and commuter benefits
• Downtown SF office with catered lunch five days a week, an in-building gym, and dogs welcome
