The Role
This company is bootstrapped and profitable, with significant ARR today and a clear path to substantial growth over the next three years. They are building an AI-powered research platform, expected to be half their revenue by 2030, betting on a specialised, fast, AI-native alternative to slow-moving incumbents. This isn't a speculative bet; it's a strategic expansion from a strong, existing business.
This is a senior IC role on their core AI platform. You'll sit alongside other Leads, setting technical direction and making compounding architectural calls. This isn't a tech-lead-from-a-distance role; you'll be hands-on, writing the trickiest agent logic and designing LLM systems. You'll drive the 12-24 month technical roadmap and talk directly to customers, without a PM filter. They hire founding-engineer types for this seat.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
The Work
- Drive the 12-24 month technical roadmap for an AI platform that automates and augments research.
- Lead the design and implementation of LLM systems: eval harnesses, agent orchestration, retrieval over research data, and observability for non-deterministic systems.
- Write the trickiest agent logic and core architectural components yourself, bringing your taste to the codebase.
- Make compounding technical decisions: where to invest in abstractions, manage complexity, or keep things crude.
- Engage directly with customers to shape product direction, without a PM layer.
What You Bring
- Production experience building and operating LLM-based products, including meaningful evals and debugging flaky agents.
- Seasoned full-stack engineer with deep backend expertise (Python) and comfort shipping frontend code.
- Experience building complex systems: async processing, queues, durable state, and robust observability.
- An AI-native approach to engineering; you use coding agents and LLMs as part of your daily workflow.
- Proven track record of making impactful architectural decisions in a fast-paced, 0-1 startup environment.
