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

STEM Search Group Job Board

Apr 28, 2026

Description

What you'll do...

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.

What we're looking for...

Professional experience shipping production-grade systems in Go or Python and TypeScript, with deep expertise in React 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. Experience limited to chat-based tools or personal productivity usage is not sufficient.
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.
Bonus Points: Deep familiarity with headless CMS ecosystems (Contentful, Sanity, Strapi), structured content schemas (Portable Text/JSON), collaborative primitives like CRDTs, or a visible history of open-source contributions to the modern web platform.
