Note: The job is a remote job and is open to candidates in USA. STEM Search Group is seeking a Staff Engineer for a new product build. The role involves leading architectural direction, owning product surfaces, and driving engineering standards while being hands-on in coding and mentoring a senior engineering team.

Responsibilities

• Lead hands-on architecture for critical parts of the platform while aligning with overall system direction, partnering closely with the Director and Principal Architect
• Own and drive major product and platform surfaces end-to-end, including design input, implementation, and production quality
• Remain deeply hands-on, writing production code while leading architectural direction and setting engineering standards
• Ship production code for a brand new product where systems, patterns, and standards are still being defined
• Build high-concurrency backend services in Go or Python to manage complex, distributed state synchronization across global regions
• Drive "Edge-first" engineering using Cloudflare Workers and Durable Objects to maintain sub-100ms latency targets in partnership with existing global infrastructure
• Establish and champion engineering standards for the team, including API design conventions, testing strategies, and cross-stack type-safety patterns
• Orchestrate heavy-duty workloads and multi-tenant infrastructure using GCP primitives like Spanner, Pub/Sub, and Cloud Run
• Build and own the integration layer between visual editing interfaces and underlying platform services, including custom extension models and SDKs
• Integrate production-grade AI scaffolding, such as RAG pipelines and streaming LLM orchestration, to redefine content automation
• Partner with the Principal Architect and product leadership to translate ambiguous visions into concrete architectural specs and phased delivery plans
• Mentor and elevate a lean, senior-heavy engineering team through architecture feedback, deep code reviews, and technical documentation

Skills

• 10 plus years of professional software engineering experience with a definitive track record of full product lifecycle ownership
• Must have directly owned and shipped a B2B product or major platform component from 'Zero-to-One'
• Expert-level capability in Go or Python plus React and TypeScript, with deep architectural roots in React and the Next.js ecosystem
• Advanced proficiency in real-time systems and API design (GraphQL, WebSockets, or SSE) with a focus on conflict resolution and live data sync
• Deep cloud-native fluency, specifically in designing and operating services at scale within GCP and Cloudflare
• AI experience is a hard requirement. Candidates must have recent, production-level experience building AI features or internal tooling
• Candidates must have owned the design of AI systems or tooling, not just integrated external APIs
• Concrete, shippable examples of building AI-driven features or internal AI scaffolding that go far beyond simple API integrations
• A 'Systems Thinking' mindset that prioritizes long-term scalability, operational simplicity, and developer ergonomics over quick fixes
• Strong ownership of engineering quality, including defining and enforcing automated testing strategies (unit, integration, end-to-end) as part of system design
• Mastery of the browser platform, including component modeling, state management, and high-performance rendering
• Deep familiarity with headless CMS architectures
• Structured content schemas (JSON/Portable Text)
• Collaborative primitives like CRDTs
• A visible history of open-source contributions

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.
