Infrastructure Engineer, Applied AI

INFRASTRUCTURE ENGINEER, APPLIED AIParadigm is a San Francisco-based investment firm focused on frontier technologies across the globe, with over $11 billion in assets under management. We make investments in companies and protocols at all stages, ranging from early-stage venture financing rounds to growth equity to liquid assets.Paradigm was co-founded in 2018 and is co-led by Matt Huang and Alana Palmedo. We've been hard at work investigating the world's most beautiful technical problems since day one. Our research-driven approach helps us build relationships with founders and entrepreneurs, but it also reflects our broader goal of accelerating the progress of frontier technology.Over the last eight years Paradigm has built some of the most used open-source software in the crypto industry, including Reth and Foundry. Earlier this year we published EVMBench with OpenAI, launched Optimization Arena and hosted the Auto Research hackathon. More recently, we open-sourced Centaur, a self-hosted runtime for multiplayer AI agents, which we've been using to transform how we work at Paradigm and Tempo.All of these were done part-time by people on Paradigm's Investing & Research team. This has made us realize that we are people-bound, not idea or impact bound. We need to grow our team to achieve our ambitions.We want to do three things:Experiment aggressively. We will push the capabilities of models, harnesses and infrastructure to the limit in service of Paradigm's broader goals in investing, research, and building.Build in public. We will get our hands dirty building useful open-source products.Invest. We will leverage our infrastructure - an area we think is still ripe for disruption with AI - to be better investors. By understanding infrastructure gaps experientially, we may incubate companies that will accrue value by addressing these gaps.As we deploy more long-running agentic capabilities, we may get into fundamental research, forecasting, model cost optimizations etc., but that is not our focus yet.We are looking for fearless engineers for this project who understand infrastructure, security, AI models, harnesses, and Slackbots. You will work directly with Georgios, Arjun, Matt Slipper, and the broader Paradigm team, alongside Tempo, and other companies that are themselves operating at the frontier.Your work will directly impact how Paradigm operates every day. If this sounds like you, reach out.ResponsibilitiesControl plane and durability: Own the core services that coordinate agent runs, keeping execution state durable and recoverable through restarts, failovers, and everything that goes wrong in production.Execution runtime: Build and harden the sandboxed, Kubernetes-based runtime that isolates agent sessions, covering provisioning, lifecycle, and the network controls that make untrusted agent code safe to run.Secrets and secure egress: Maintain the credential model that lets agents call third-party APIs without ever holding raw keys.Reliability and observability: Own monitoring, alerting, incident response, and the failure-recovery behavior the system relies on.Self-hosted deployment: Keep Centaur something any organization can run inside its own walls, with clean deployment, sane configuration, and painless upgrades.Qualifications and ExperienceA track record of building world-class productsExperience applying modern AI and software systems to solve complex, ambiguous problems end-to-endComfortable navigating everything from foundational models to full-stack product deliveryPragmatic, product-minded builder who cares about solving real problems rather than overfitting to academic ML goalsAbility to work autonomously and as a collaborator on the teamAttributesExceptional team playerExtreme open-mindednessClarity of thoughtClear and concise communication (both written and verbal)Technical depth; analytical; rigorousHighly curious; fast learnerAbility to bridge technical and investing mindsetsInterest in frontier technologies and crypto markets
