You make the hard technology calls early (durable execution engine, vector store, tenancy model) and you write code for the hardest piece of each release.\nResponsibilities\nOwn the target architecture and the architecture decision records; decide the durable workflow engine, tenancy model and data-store boundaries in the first two weeks.\n\nDesign and hands-on build the semantic layer's resolution engine (plain-language definition → systems, tools, rights) with the AI engineers.\n\nSet the standards the team builds to: API contracts, event schemas, adapter contract, state schema for the supervisor graph, security baseline.\n\nRun design reviews for every epic; unblock engineers on hard problems; review the code that matters.\n\nOwn non-functional requirements - scalability, isolation, latency budgets, data retention, disaster recovery - and prove them with load tests and drills before Go-Live.\n\nBe the technical voice with pilot customers' architects and security teams.\n\nMust have\nDesigned and shipped a multi-tenant SaaS or platform product used at scale; can explain the trade-offs you made and what you would change.\n\nDeep, current knowledge of distributed systems: durable workflows or sagas, event streaming with Kafka, idempotency, back-pressure, failure modes.\n\nStrong data architecture across relational, in-memory and vector stores; you know what belongs where and why.\n\nWorking experience with LLM-based systems in production: tool calling, agent orchestration frameworks (LangGraph or equivalent), RAG, evaluation. Not slideware - you have debugged a misbehaving agent.\n\nEnterprise integration experience: connecting to CRMs, ERPs and legacy systems over REST, SOAP, JDBC, files; authentication and rate-limit realities.\n\nSecurity architecture for B2B software: RBAC, tenant isolation, secrets, PII handling; comfortable in a pen-test readout.\n\nStill writes production code, primarily Python; reads TypeScript.\n\nGood to have\nTemporal in production. Apache Camel or another integration framework. Kubernetes operations at scale.
