[Remote] Sr. Full-Stack Engineer (New Product Build - Go/Python, React, TS, Next, GCP, Cloudflare)
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.
