Plain is hiring a Founding Data Engineer to build and own the company's data warehouse, core models, and customer data spine that powers product decisions, analytics, and AI features across the organization. You'll rebuild the data warehouse architecture from the ground up, establish clean pipelines and event taxonomy with Engineering, deliver foundational datasets for analytics and in-app reporting, implement data observability and quality checks, and enable self-serve analytics across teams. The ideal candidate has hands-on experience building modern analytics stacks end-to-end (warehouse, transformations, semantic layer, governance), is strong with SQL and BigQuery/dbt, and has shipped user-facing analytics or AI retrieval layers using real-time platforms like Tinybird or ClickHouse. Plain is a well-funded B2B customer support platform trusted by companies like Cursor, Vercel, and Granola, operating in a market being reshaped by AI. This is a greenfield, hands-on individual contributor role—not a management position—that requires comfort with ambiguity and prioritizing shipped impact over perfect abstractions.

Plain is a B2B customer support platform trusted by companies like Cursor and Raycast to unify interactions across channels and leverage AI to shift support from reactive to proactive. The Senior Product Engineer role sits on the AI infrastructure team and involves owning end-to-end AI features—from agents and assistants to insights—while designing backend services, APIs, and data pipelines that enable the company to build AI capabilities quickly and safely. You'll need 3+ years of backend engineering experience shipping AI products in the OpenAI/Anthropic era, hands-on expertise with LLM orchestration and optimization, familiarity with RAG architectures and AI observability, and a product-minded approach that measures success by user impact rather than technical novelty. The position is hybrid (3 days/week in the London office) and explicitly targets applied AI engineers, not researchers—the company is skeptical of AI-as-gimmick and prioritizes precision over hype. This is a high-ownership individual contributor role at an early-stage startup where things change quickly; they explicitly state this is not for someone seeking management, big-company perks, or primarily academic ML experience.

Plain is a B2B customer support platform that unifies multi-channel customer interactions and uses AI to transform support workflows, backed by customers like Cursor and Raycast. This is a backend/full-stack engineering role on one of three teams—Core Product (channels and data models), Developer Infra (internal tools and tooling), or Backend Architecture (complex systems and APIs)—where you'll own problems end-to-end from infrastructure to feature launch, balancing shipping speed with long-term product health. You'll need proven experience at product-led B2B SaaS companies, strong technical chops with distributed/serverless systems, and the autonomy to prioritize between taking shortcuts and investing in infrastructure; you should thrive with ambiguity and be equally comfortable in architectural and customer conversations. The role is hybrid (3 days/week in London), Series A stage with competitive but not enterprise-scale compensation. This is explicitly not a management role and not suited for people seeking novel tech learning as a primary motivation—Plain favors proven, productive solutions over experimental ones.
