Apply for this roleAbout Plasma
AI is crossing a threshold. Systems of agents can now do consequential work unattended, for hours at a time, and most companies still lack the layer that would let them trust it. Plasma builds that layer: delegation with limits, live oversight, and one record of everything learned. Infrastructure for an AI operable world.
We come from places where autonomy already carried real stakes. Our founders built Omega Strategies, an autonomous trading firm that ran hundreds of probabilistic models against live capital. The team's experience spans Palantir, Subquadratic, D. E. Shaw, J.P. Morgan, Google, TPG, and Morgan Stanley, founding-team startup experience, and more.
The Opportunity
We're looking for a founding-level platform engineer to work alongside our CTO on Plasma's core infrastructure. You'll build the data pipelines, agent orchestration layers, API infrastructure, and reliability foundations that everything else runs on.
We're looking for a commercially minded, product-oriented engineer from a top AI lab or quantitative finance background. If you've spent time somewhere where the bar for production systems is unusually high and want to build something from scratch, this role is for you.
What You'll Work On
Core Platform: Own the infrastructure (compute, storage, APIs, pipelines) Plasma's systems run on. Architectural decisions you make early will compound for a long time
Agent Infrastructure: Build the orchestration, observability, and governance controls that let AI agents operate reliably in production
Data Systems: Design scalable pipelines where correctness and auditability are requirements, not nice-to-haves
Reliability & Observability: Establish the monitoring, alerting, and incident response practices that make Plasma's systems dependable
Technical Bar: Set the standard for engineering quality and shape architectural decisions
What We're Looking For
Deep expertise in distributed systems, backend infrastructure, or data engineering
Experience building and operating data-intensive systems in production (pipelines, streaming, warehouses, enterprise orchestration, model serving)
Familiarity with AI/ML infrastructure: LLM systems, agent frameworks
Comfort with cloud infrastructure (AWS, GCP), modern DevOps practices, and large-scale enterprise integrations
Background at an AI lab, top quantitative firm, or high-rigor infrastructure team is a strong plus
Exceptional judgment about when to build, when to buy, and when to keep it simple
