About the role
- 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
