Senior Python Engineer: AI Agents & Forecasting

About this role

WE'RE BUILDING AI THAT PREDICTS THE FUTURE. LITERALLY.

THE COMPANY

Numinous https://numinouslabs.io is building the world's most advanced super-forecasting AI agents. We're creating autonomous systems that ingest real-world data, reason through complex scenarios, and produce predictions for the highest-stakes decisions on the planet. Think hedge funds, traders, governments, and Fortune 500 companies.

Right now, we're selling predictive intelligence to hedge funds and operating in prediction markets. But that's the starting point, not the ceiling. We're a small team, early-stage, well-backed, and moving fast.

Our mission: To build forecasting AI that fundamentally changes how critical decisions get made.

OUR CULTURE

We operate like founders, not employees. Everyone here has skin in the game and the autonomy to make real decisions. We move fast, communicate directly, and don't hide behind process. If something needs doing, you do it. If something's broken, you say it.

We value missionaries over mercenaries. We want people who care about the mission, not just the paycheque. The kind of people who'll stay up late because the problem is interesting, not because someone told them to.

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. This isn't gluing APIs together. You'll be designing the systems that score, rank, and incentivise AI forecasting agents in live, competitive environments.

Day to day, you're deep in backend architecture, building production-grade agent orchestration, designing data pipelines, and solving problems at the intersection of software engineering and quantitative forecasting. You'll work directly with the founders. There are no layers between you and the decisions that shape the product.

WHAT YOU'LL BE DOING

- Unifying the different parts of the stack. The network, signal layers, and forecasting architectures need to work together as one coherent system.

- 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.

BAD NEWS

- We're early. The engineering function is still being built.

- Documentation is thin and processes are light

- Priorities will shift and things will break

- If you need a mature engineering culture with established practices, this isn't the role yet. You'll be helping build that culture, not inheriting it.

GOOD NEWS

- More ownership, influence, and impact in 6 months than you'd get in 5 years at a bigger company

- Technical co-founders who are direct, move fast, and actually understand what you're building

- No politics, no layers, no waiting for approval

- The problem is genuinely unsolved and the market is enormous

- If we get this right, you'll have built the infrastructure behind the world's most advanced forecasting AI.

YOUR MISSION

Make the Numinous platform into a self-improving world model with the most accurate forecasts in the world. You exist to turn our vision of self-improving superhuman AI forecasting into a reality, building the systems that allow agents to get smarter, faster, and more accurate over time.

WHY JOIN NOW

This is founding-engineer territory. The team is small, the problem is unsolved, and the market is massive. You're not joining a machine that's already running. You're building it. The architecture decisions you make in the next 6 months will define the platform for years. You'll have direct influence over the product, the technical direction, and the culture of the engineering team as it grows.

In 12 months this role won't look like this. The team will be bigger, the foundations will be set, and the opportunity to shape everything from scratch will be gone. Right now, it's all open.

WHAT GOOD LOOKS LIKE

At 3 months: There's a production-grade forecaster in one category. Targets are linked to signals, connected to the network, with experimentation underway on forecasting architectures. You're making architectural decisions independently and contributing to technical strategy, not just executing tickets.

At 6 months: The signal pipeline has an inductive process, a world model sits on top, and there's a sellable product for clients. You've unified the different parts of the stack (the network, signal layers, and forecasting architectures) into something coherent and powerful.

At 12 months: The platform handles complex targets across multiple verticals including commodities, politics, and beyond. There's a provable edge that unlocks serious commercial conversations. You're a technical leader in the company, not just an engineer.

SKILLS & EXPERTISE

- 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

EXPERIENCE

- 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…
