Note: The job is a remote job and is open to candidates in USA. STEM Search Group is seeking a Senior Full-Stack Engineer for a new product build. The role involves shipping production code for a collaborative content platform, contributing to architecture, and integrating AI-driven features.

Responsibilities

• You will be expected to ship production code for a brand new product, not just extend or maintain existing systems
• Contribute to the architecture and scaling of a real-time, collaborative content platform supporting global users
• Build high-concurrency backend services in Go or Python to manage complex, distributed state synchronization across regions
• Execute compute at the Edge via Cloudflare Workers and Durable Objects to maintain sub-100ms latency for a global user base
• Design and maintain robust, type-safe API contracts that bridge high-performance backends with Next.js frontends
• Integrate LLMs and RAG pipelines directly into the product to automate complex workflows and drive AI-assisted content generation
• Orchestrate heavy-duty data workloads and messaging systems using GCP primitives like Pub/Sub, Spanner, and Cloud Run
• Own the end-to-end delivery of complex features, contributing to architectural decisions while partnering closely with senior engineers
• Collaborate with a lean, senior-heavy team to establish engineering standards, deployment pipelines, and a 'quality-first' culture
• Operate in a high-ambiguity environment where you are expected to translate product direction into technical execution without fully defined specs

Skills

• 5+ years of professional experience shipping production-grade systems in Go or Python and TypeScript
• Deep expertise in React and the Next.js ecosystem
• Hands-on experience with Cloudflare's Edge platform and GCP's cloud-native services, specifically for high-traffic SaaS products
• Advanced proficiency in API design (GraphQL, WebSockets, or SSE) with a focus on real-time data flows and concurrent collaboration
• Concrete, shippable examples of building with AI, such as streaming token responses, vector database integration, or custom LLM tooling
• Active AI fluency is required; candidates must have shipped AI-driven features or built internal tools using AI
• A 'Systems Thinking' mindset that prioritizes global performance, security, and long-term maintainability over tactical patches
• Comfort operating in a high-autonomy environment where you are responsible for your own QA and delivery without a safety net
• Engineering pedigree from a high-growth SaaS product shop or developer-tooling company where the API is the core offering
• U.S. work authorization without sponsorship is required
• Deep familiarity with headless CMS ecosystems (Contentful, Sanity, Strapi)
• Structured content schemas (Portable Text/JSON)
• Collaborative primitives like CRDTs
• A visible history of open-source contributions to the modern web platform

Benefits

• Quarterly/annual bonus plus equity package.
• Health, dental, and vision insurance.
• Results-oriented PTO, sick days, and paid holidays.
• Parental leave, family planning, and monthly wellness/learning stipends.
