Senior / Lead Infrastructure & Operations Engineer - (AI Startup) Boston, MA – On‑site We’re partnering with a well‑funded, stealth‑stage AI startup at the intersection of frontier AI research and fundamental physics. They’re building AI systems that can discover new physics at scale. This is a foundational infrastructure role: you’ll own the platform every other engineering team ships through. The Opportunity Our client is looking for a senior infrastructure engineer to own the path from commit to production for a codebase where most commits are written by AI agents. Human review doesn’t scale at that velocity; CI does. What CI enforces is the architecture. You’ll decide what CI enforces and build it, across a cloud estate spanning GCP and specialist GPU providers, on a network you design and a failover you rehearse. This is being built from a thin starting point, not inherited from a mature platform. What You’ll Do as Senior / Lead Infrastructure & Operations Engineer Own end‑to‑end CI/CD: pipelines, staged environments, promotion with real gates. The artifact that passes tests is the artifact that runs. Run the cloud estate as code across GCP and specialist GPU providers: org structure, IAM, quotas, and provisioning so engineers don’t file tickets for basic needs. Repo and permission management counts as infrastructure here. Design and operate the underlying network: VPCs/subnets across providers, interconnects, DNS, and cross‑cloud failover that is actually rehearsed. Make onboarding a system: treat time‑to‑productivity as an infrastructure property. Build the “paved road” with environments, docs‑as‑code, and defaults that make the right thing the easy thing. Lead incidents and reduce toil with code, preferring self‑service abstractions over tickets. What You’ll Bring as Senior / Lead Infrastructure & Operations Engineer 5+ years building and operating production infrastructure at companies known for engineering rigor (e.g., Stripe, Cloudflare, Datadog, Snowflake, Databricks, Google, Netflix, or comparable). Deep fluency with infrastructure as code (Terraform, Pulumi, or similar), CI/CD systems, Kubernetes, and at least one major cloud (GCP preferred; AWS acceptable). Experience building CI/CD from 0→1, not just maintaining a mature system. You can explain mechanically how you’d cut a build or registry bill; container build and registry economics are something you reason about before they show up on an invoice. Hands‑on experience running a multi‑account cloud estate as code, ideally with multi‑cloud networking and a rehearsed failover. A track record of leading incidents and systematically reducing toil with automation and self‑service platforms. Nice to Have Built CI/CD or release engineering from scratch at a fast‑growing company. Strong FinOps instinct: cloud cost at account and architecture level (commitments, egress, idle spend, unit economics). Experience with specialist GPU‑cloud providers (e.g., Modal, CoreWeave, or equivalents) and the account/quota/network realities of running across them alongside a major cloud. Production observability with OpenTelemetry, Prometheus, Grafana, or similar. Experience supporting machine‑generated or unusually high‑velocity commit patterns.

That number is real. WorkMundi's database shows 144,883 open engineer roles across the world. India has the most with 31,687 jobs, followed by the United States with 30,084. If you just finished reading one job ad and felt paralyzed by choice, you're not alone—but this scale is actually an advantage. It means you can afford to be selective.
Start by geography and language. The majority of engineer ads—117,837 of them—have the job posting text written in English. Use that as one filter, but remember: the ad text language tells you nothing about whether the role actually requires you to speak English day-to-day. Read the job description carefully. Then check which countries have the volume you're targeting. Singapore, Poland, and Australia round out the top five after India and the US.
Next, learn who's hiring. Accenture has posted 2,801 engineer roles. andurilindustries, speechify, and jobgether are also actively recruiting. If you're applying to one of these names, research their hiring patterns and interview style before you apply. That homework pays off.
When you interview, expect the question every engineer hears: 'Tell me about a time you had to debug a problem that wasn't in your job description.' Have a specific story ready—not a general one. Name the tools, the deadline pressure, and what you learned. Hiring managers listen for whether you see problem-solving as part of the role itself, not a favour.
