openrouter - Solutions Architect
Requirements
• 7+ years in a technical, partner- or customer-facing role (solutions architect, partner engineer, sales engineer, forward-deployed engineer) at an API-first or developer infrastructure company. • Hands-on depth in API platform design: authentication and authorization (OAuth 2.0, PKCE, token exchange, API key management), multi-tenancy, rate limiting, webhooks, and usage metering. • Experience designing embedded or platform integrations where account ownership, billing, and data flows were part of the design. • A track record of writing technical specs that engineers actually built from. • Comfortable leading a call with a senior technical leaders internally and externally • Strong written communication. A large part of this job is clear documents. • Genuine technical curiosity about OpenRouter and our partner’s products and the AI tools and infrastructure ecosystem more broadly. • Experience at an API or platform company with a partner or embed program • Familiarity with gateways and proxies, trust and safety or abuse systems, or billing and metering infrastructure. • Hands-on time with LLM APIs, agents, MCP, or multi-provider routing. • Personal projects involving AI agents, self-hosted models, or infrastructure tinkering.
Responsibilities
• Partner with Business Development Managers and Product Managers on strategic partnership opportunities, leading technical discovery, solution design, and architecture discussions with customer engineering and infrastructure teams. • Run technical discovery with partner product and engineering teams, map their product to our integration patterns, and present the options with honest tradeoffs. • Capture partner requirements and get launch-blocking needs, scale needs, and compliance needs on paper before commercial terms are agreed • Turn partner requirements into integration specs our engineering team builds from • Keep a single current list of open technical questions and decisions for every active partner deal, and chase them to resolution. • Stand up working integrations with design partners, debug in real time, and drive to a clear technical yes. • Build reference architectures, integration guides, and demo environments so future partner integrations take a fraction of the effort of the first. • Work closely with Product, Engineering, and Customer Engineering to bring customer and market signal back into the roadmap, and to make sure partner feedback shapes what we build next. • Stay technically sharp. Keep pace with the fast-evolving LLM landscape — new models, providers, infrastructure patterns, and the tools your customers are already using.
