You can refer people through our form https://airtable.com/appYVvzDrNdbVKIaK/pagLIE65fzwkJz6NB/form. We’re hiring a member of technical staff to work closely with the founding team. You'll shape both our products and research direction. Key Responsibilities: - Backend engineering: Design and build scalable infrastructure and systems for AI agents, including containerization, and performance optimization - Machine learning: Contribute to agent science research, and create evaluations for agent performance and behavior - Frontend engineering: Develop oversight interfaces and frontend systems for coding agent monitoring and control - Shape product strategy and research direction in collaboration with the founding team ## About Fulcrum ## Company Overview - **One-liner**: Fulcrum is an AI lab building infrastructure and interfaces for human-AI collaboration in software development, with a focus on "elicitation" to extract optimal performance from AI models. - **Entity Type**: Private (early-stage startup) - **Headquarters**: Not publicly available on their website or careers page; likely US-based (founders with MIT affiliation). - **Founded**: 2025 (GitHub org created February 27, 2025) - **Founders**: Founders are from MIT’s AI alignment group, with top-tier ML research publications (NeurIPS, COLM), open-source contributions, and international olympiad medals. Specific names are not listed on the website. ## Core Business - Primary industry/industries: AI/ML Infrastructure, Developer Tools, Agentic Software - Target customers: B2B; AI researchers, engineering teams, and enterprises building multi-agent software systems - Mission or purpose statement: "AI agents are going to write most of the world's software. We want to make sure humans can understand, control, and trust what they build." ## Products & Services - **[Druids]**: A batteries-included, open-source Python library to coordinate and deploy coding agents across machines. It provides a state machine framework, pre-warmed cloud VMs, and a UI/CLI/MCP for managing agent teams. Solves the bottleneck of human oversight by scaling intent across many agents with verification and control flow. ## Market Standing - **Valuation/Market Cap**: Not disclosed - **Key Metric**: Total Funding—not publicly disclosed (likely angel or pre-seed stage). Open-source community traction: Druids launch (March 2026) with beta users applying it to open math problems, ML "autoresearch," and software optimization. - **Notable Investors/Partners**: Not publicly disclosed - **Growth Signals**: Rapidly building a developer community (Druids is open-source); 21 public repositories on GitHub; early beta users in research and engineering; actively hiring for technical staff and generalist roles. ## Competitive Advantages - **Deep technical moat in elicitation**: Focus on getting the best outputs from frontier models by structuring tools and processes, combined with infrastructure to measure output quality. - **Founding team caliber**: Top-tier ML research (NeurIPS, COLM), open-source software contributions, international olympiad medals, and leadership at MIT’s AI alignment group. - **Unique product philosophy**: Treats AI agents as a distributed systems problem (state machines, VMs, parallelism) rather than a prompt engineering problem—offering reproducibility and control at scale. ## Strategic Focus - **Open-sourcing infrastructure**: Druids is the core product, released open-source to build a community and ecosystem. - **Human-AI collaboration**: The company's core thesis is that smarter models alone aren't enough—human oversight scaling requires new infrastructure. - **Research-driven**: Continues to measure model capabilities, find failure modes, and develop elicitation techniques for "the hardest and fuzziest tasks." ## Why Work Here - **High-impact mission**: Work on foundational infrastructure for how humans will control and trust AI-generated software. - **Elite technical team**: Colleagues with top-tier ML publications, open-source influence, and MIT alignment background. - **Culture of research and engineering**: The team publishes research, builds open-source software, and operates at the intersection of ML research and systems engineering. - **Early stage**: Opportunity to shape the company’s product, culture, and direction. - **Remote/hybrid**: Not specified on careers page; likely flexible for early-stage startup. - **Hiring roles**: Currently seeking a "Member of Technical Staff" and a "Generalist"—general skills valued; no explicit degree or experience requirements listed, just impact orientation. ## Sources 1.
