Our platform helps users find mentors, peers, and guides based on shared experiences—not just keywords. We're a lean, AI-native team. We don't scale by adding headcount. We scale by shipping faster with better tools. If you've built features in an afternoon that used to take a sprint, you'll fit right in. The Role You'll be the technical owner of our entire stack. Not a "lead" managing a growing team—an owner who ships, architects, and multiplies output through AI agents and a small bench of specialist contractors. This role is for someone who already treats Claude, Cursor, and Copilot as their default development environment. Someone who's experimented with agentic workflows—not as a novelty, but because it's faster. You'll report to the Head of Product and work directly with our founders and customers. What You'll Own The Stack Full ownership of our GCP/Vertex AI infrastructure, APIs, and frontend Architecture decisions that will scale from dozens to thousands of users Production reliability, deployment pipelines, and technical debt management Security, compliance, and data integrity across all systems Contractor & Agent Orchestration Define deliverables for specialist contractors (frontend, DevOps, ML) Review PRs from both humans and AI-generated code Build and maintain our internal agentic workflows—treating AI agents as asynchronous team members Document patterns so contractors and agents can work autonomously against clear specs Agentic Development Culture Pioneer our "1 dev × N agents" operating model Build reusable prompts, agent configs, and automation scaffolding Establish workflows where AI handles first drafts, boilerplate, tests, and docs—you handle architecture, edge cases, and judgment calls Continuously evaluate new AI dev tools and integrate what works What You'll Ship (First 90 Days) Audit and document the current stack; identify tech debt and quick wins Establish CI/CD and deployment workflows optimized for rapid iteration Ship at least one customer-facing feature end-to-end Build the contractor onboarding playbook (specs, PR standards, async communication) Implement at least one agentic workflow that measurably accelerates development What We're Looking For Technical Depth 5+ years building production systems across frontend and backend Strong in TypeScript/JavaScript and Python Hands-on experience with GCP (Vertex AI, Cloud Run, BigQuery) or equivalent Production experience integrating LLM APIs (Anthropic, OpenAI, Google) Comfortable with PostgreSQL, Redis, and event-driven patterns AI-Native Mindset You already use AI coding assistants daily—not experimentally, habitually You've built or experimented with agentic workflows (LangGraph, CrewAI, custom orchestration) You think in terms of "what can I delegate to an agent?" before "what do I need to build?" You're curious about prompt engineering, evals, and AI reliability—not just AI hype Ownership & Judgment You've owned systems end-to-end, not just contributed to them You're comfortable making architecture decisions without a committee You know when to ship fast and when to slow down for quality You communicate clearly in writing—specs, PRs, async updates Contractor & Collaboration Skills Experience working with or managing contractors/freelancers Ability to write clear specs that enable autonomous work Comfort giving direct feedback on code quality and deliverables No ego about where good code comes from—human or AI What We're NOT Looking For Someone who wants to build and manage a large engineering team Pure specialists (frontend-only, ML-only) who don't want to go full-stack Engineers who are skeptical of AI tooling or prefer to "do it themselves" Anyone who needs extensive process, standups, or structure to be productive Tech Stack Frontend: React, Next.js, TypeScript, Tailwind CSS Backend: Python (FastAPI), Node.js, PostgreSQL, Redis AI/ML: Vertex AI, Anthropic Claude API, LangChain/LangGraph, Vector DBs Infrastructure: GCP (Cloud Run, Cloud SQL, Pub/Sub), Terraform, GitHub Actions Dev Tools: Cursor, Claude, GitHub Copilot, Linear How to Apply Send to careers@sapienceai.co: Your resume or LinkedIn A brief note (2-3 paragraphs) covering: A system you've owned end-to-end and what you learned How you currently use AI tools in your development workflow What "agentic swarming" means to you (or what you'd want it to mean) No cover letter required. No agencies.
