Dex
Dex is an AI recruiter agent that helps you run your job search. Tell Dex your stack, seniority, and what you want to build. We will manage your applications and surface other opportunities that are a fit.
The role
Multi-agent AI systems are proliferating, but the foundational shared-state infrastructure they need to run reliably in production is largely unsolved. We are building that layer: sub-80ms retrieval with ACL-gated state, enabling agents across diverse frameworks to coordinate without conflict. This is foundational infrastructure for an exploding category, solving a critical, unmet need.
As a Founding Engineer, you will own the core retrieval and state system end-to-end. This isn't just another feature role; you'll set the technical direction, make critical infrastructure and API decisions that compound for years, and ship the integrations that bring our first production users on. You'll join a small, in-person team, shaping a product from first principles.
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
- Design and implement low-latency distributed systems for sub-80ms state retrieval.
- Architect and build robust access control, consistency, and multi-tenancy into the core shared-state layer.
- Develop the SDK surface for seamless integration with agent frameworks like LangGraph, CrewAI, and AutoGen.
- Define the data model, API shape, and operational posture for a foundational infrastructure product.
- Drive the technical direction and ship integrations to onboard early production users.
What You Bring
- Proven experience building low-latency distributed systems in production, with a track record of sub-100ms retrieval at scale.
- Deep understanding of access control, multi-tenancy, and the operational challenges of shared-state systems.
- Hands-on experience with or integrating against modern agent frameworks (e.g., LangGraph, CrewAI, AutoGen).
- A builder's mindset: comfortable with ambiguity, eager to own a surface end-to-end from design to production support.
- Ability to work predominantly in-person with a founding team in Canary Wharf, London.
