We unify what an agent needs to act in the world — compute and sandboxes, memory, identity, spend controls, storage and queues, monitoring — provisioned together as one thing, not handed over as a framework to assemble yourself. We have assembled a world-class team with deep infrastructure and payments DNA to build the operating system for machines. Our founder ran payments engineering at Shopify for five years and built an autonomous consumer agent company before that. We raised a $35M Series A led by Dragonfly in August, bringing us to $50M total. Accel led our seed; Menlo Ventures and Anthropic are also behind us. The models are the brain. We're the spine. ## About the Role As a Staff AI Platform Engineer, you'll help define the technical direction of the platform from the ground up. You'll architect distributed systems that power AI agents in production, establish engineering best practices, and partner closely with leadership to shape both the technology and the company. This is an opportunity to join early and have an outsized impact on the architecture, culture, and product strategy of an AI infrastructure company. ## What you'll do - Architect the core platform that powers AI agents in production. - Design distributed systems for agent orchestration, execution, memory, tool calling, workflow coordination, and communication. - Build reliable infrastructure that enables AI agents to operate safely and efficiently across enterprise environments. - Lead the technical design of foundational platform capabilities, balancing performance, reliability, extensibility, and developer experience. - Drive architecture decisions across backend systems, APIs, infrastructure, and AI runtime services. - Establish engineering standards for scalability, observability, security, and operational excellence. - Partner with product and engineering leadership to translate emerging AI capabilities into production-ready platform features. - Mentor engineers through design reviews, technical guidance, and hands-on collaboration. - Lead complex, cross-functional initiatives from concept through production. We're looking for someone who has - 8+ years of experience building large-scale backend systems, distributed systems, or developer platforms. - Experience operating technical leadership at the Staff or Principal Engineer level, or demonstrated equivalent scope and impact. - Strong programming skills in Python, Go, Typescript, or similar languages. - Experience building developer platforms, SDKs, or API-first products that prioritize reliability, scalability, and developer experience. - Experience working with modern AI systems, including LLMs, tool calling, structured outputs, retrieval, or agentic workflows. - Strong systems thinking with the ability to simplify complex technical problems. - A track record of driving technical strategy while remaining hands-on. - Experience with event-driven architectures, workflow engines, or distributed execution systems. ## Nice to have - Experience building production AI agent platforms or orchestration frameworks. - Familiarity with LangGraph, OpenAI Agents SDK, CrewAI, AutoGen, Temporal, or similar orchestration technologies. - Experience with vector databases, retrieval systems, and knowledge infrastructure. - Experience with LLM serving technologies such as vLLM, SGLang, or TensorRT-LLM. - Contributions to open-source infrastructure or AI projects. ## Why Sapiom We're building the infrastructure that will power the next generation of AI applications. Rather than building a single AI product, we're creating the platform developers use to build intelligent, autonomous systems that can coordinate work, integrate with enterprise software, and execute complex workflows reliably. As one of the earliest senior engineers, you'll have significant influence over our architecture, engineering culture, and product direction. You'll help define the technical foundation of a company solving some of the hardest problems in production AI. ## About Sapiom ## Company Overview - **One-liner**: Sapiom builds the financial access layer that allows AI agents to securely purchase and use software, APIs, data, and compute through a single key, eliminating vendor accounts and billing relationships. - **Entity Type**: Private (Seed stage) - **Headquarters**: San Francisco, California, United States - **Founded**: 2025 - **Founders**: Ilan Zerbib ## Core Business - **Primary industry/industries**: AI infrastructure, Payments, API orchestration - **Target customers**: B2B – AI agent developers, vibe-coding platforms (e.g., Lovable, Bolt), and any company building autonomous agents that need to transact with external services. - **Mission or purpose statement**: "Build the access layer for the agentic economy" – create infrastructure that lets AI agents transact safely with the real economy. ## Products & Services - **Access Network**: The core execution engine. One API key replaces every vendor account, credential, and billing relationship. Services are metered per use (no subscriptions or minimums). Capabilities include: - **User Authentication**: Agents verify users via SMS, OTP, transactional messaging – billed per verification. - **LLM Inference**: Access 400+ language models from leading providers with automatic provider selection – billed per token. - **AI Search**: Live web and structured data queries with real-time results and source citations – billed per query. - **Voice and Audio**: Generate speech, transcribe audio, create sound effects – billed per minute. - **Image Generation**: Create images from text prompts – billed per generation. - **Video**: Generate, transform, and subtitle video content – billed per generation. - **Web Extraction**: Browse, scrape, and interact with websites – billed per session. - **Compute**: Run code in serverless containers – billed per execution. - **Messaging**: Publish messages, manage queues, schedule tasks – billed per message. - **Databases**: Provision Redis, vector, search, Postgres databases – billed per operation. - **Filesystem**: Store, organize, and serve files autonomously – billed per operation. - **Integration Options**: MCP (zero-code), Skills (one command), SDK (full control). ## Market Standing - **Valuation/Market Cap**: Not publicly disclosed - **Key Metric (Private)**: Total funding raised – $15.75 million (Seed round, led by Accel, closed February 2026) - **Notable Investors/Partners**: Accel (lead), Okta Ventures, Gradient Ventures, Array Ventures, Menlo Ventures, Anthropic, Coinbase Ventures. Founder Ilan Zerbib previously Director of Engineering for Payments at Shopify. - **Growth Signals**: Team of ~8 employees (as of mid-2026) with 20+ open roles posted; strong backing from top-tier funds; early adoption by vibe-coding platforms; monthly headcount growth of +11.1% per LinkedIn. ## Competitive Advantages - **Zero-friction access**: A single API key replaces dozens of vendor accounts, credentials, and billing relationships – agents get immediate access to any paid service without manual setup. - **Metered, transparent pricing**: No subscriptions, no minimums – pay only for what agents actually execute. This aligns cost with usage and reduces overhead. - **Deep payments & infrastructure DNA**: Founder built Shopify’s payments infrastructure; team hails from Modern Treasury, Google, Shopify, and other high-scale fintech/infra companies. - **Protocol rather than catalog**: The Access Network allows agents to use any paid API on the internet without needing a pre-curated catalog – extensible by design. - **Backed by Anthropic**: Strategic investment from a leading AI lab ensures alignment with frontier agent capabilities. ## Strategic Focus - **Current priorities**: Scaling the Access Network to more B2B AI agent builders and vibe-coding platforms; hiring aggressively (20+ open roles) to expand engineering, product, marketing, and developer relations; building identity, policy, settlement, and risk layers for machine commerce. - **Direction for growth**: Become the default economic substrate for autonomous agents – moving from B2B to eventually enabling consumer AI agents to transact independently. ## Why Work Here - **Culture highlights**: Small, high-trust team; senior hires given context not orders; strong opinions weakly held; decisions made in writing; "high-intensity ownership" with meaningful founder-level equity. - **Remote/hybrid/office policy**: On-site in San Francisco, CA. Regular team offsites for deep work and relationship building. - **Notable perks**: - Top-tier health coverage (medical, dental, vision – fully covered for employees and dependents) - Learning budget (books, conferences, courses) - Best-in-class hardware (no budget approval delays) - Flexible time off (no vacation tracking; "own your recovery fully and effectively") - Mission-critical work at extreme velocity ## Sources 1.
