Principal Full-Stack Engineer | AI Start-Up | Remote, with occasional onsite (Germany)I am partnered with an AI startup, backed by a significant round of funding looking for a principal-level software engineer who wants to apply big-system thinking to a smaller, faster environment.You’ll be building production software that sits directly on top of large-scale generative models. That means turning research outputs into stable interfaces, reliable workflows, and product surfaces that hold up under real usage.What you’ll doDesign and own full stack systemsBuild frontend applicationsOwn backend APIs, data models, auth boundaries, and async processingDesign event-driven pipelines for large media ingestion, background processing, retries, and failure recoveryWork directly with research to define clean contracts between model outputs and product interfacesRaise engineering standards through architecture, reviews, and example implementationsHow the stack looks in practiceTypeScript end to endReact with Tailwind and Radix-based component patternsConvex-style backend architecture with strongly typed queries, mutations, actions, and realtime stateAsync-first design with explicit failure handling and observabilityAWS used narrowly and intentionally for Lambda, S3, and event triggersAbout youYou operate at senior, staff, or principal level in a high-bar engineering environmentYou are comfortable owning ambiguous problems without layers of review or processYou think about systems, invariants, and failure modes as much as codeYou can move fast without compromising quality of workYou want your decisions to matterNice to haveExperience productising ML or LLM-backed systemsPython for tooling or model-adjacent workExperience with serverless or backend-as-a-service architecturesBenefits of the roleOwnership of complete systemsDirect influence over technical/product decisionsClear line of sight from code to real users and outcomesClose collaboration with research and productHigh trust environment with strong technical autonomyCompetitive compensation with meaningful equity upsideRegular in-person time with a small senior team, without giving up remote flexibilityAccess to whatever tools or benefits you need to help you excelIf you’re looking for a technically demanding role with real impact and very little overhead, apply now
