B2B • Recruitment

Spoon is a staffing and startup enablement firm that places experienced startup generalists—former founders and multi-skilled operators—into early-stage teams to execute projects, build systems, and fill multiple roles quickly. They offer flexible, cost-effective support across growth, marketing, product, operations, user research, data analysis, and talent acquisition, and help hire long-term team members. Spoon serves startups internationally (US, UK, EU) and positions itself as a practical cofounder-like resource to accelerate scaling without the overhead of multiple specialist hires.

📋 Description

• You'll architect and build the core infrastructure of the Numinous platform. This is the backbone that allows autonomous AI agents to ingest data, reason, compete, and forecast. • Designing and building the agent orchestration pipeline that allows AI forecasters to ingest data, reason, and produce predictions. • Building and optimising the signal pipeline that feeds real-world data into forecasting models. • Experimenting with different forecasting architectures to find optimal approaches for linking targets to signals. • Writing production-grade Python that handles complexity at scale, not scripts that work in a notebook. • Contributing to technical strategy alongside the founders. You'll have a voice in what gets built and why. • Evaluating and vetting technical candidates as the engineering team grows.

🎯 Requirements

• 5+ years building production-grade Python backends. You know the internals, not just the syntax. • Hands-on experience with LLM orchestration frameworks such as LangChain or LangGraph (agent memory, tool calling, state management) • Dagster in production (assets, sensors, partitions) or equivalent pipeline orchestration • Strong backend fundamentals including API design, async programming, and database modelling • You've built systems that had to work reliably at scale, not just pass a demo • Worked at an early-stage startup or high-growth environment. You understand the pace. • Built and shipped production systems, not just prototypes • Comfortable being the most senior engineer in the room, or the only one

🏖️ Benefits

• Equity: Competitive for the right candidate
