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.
What You Will Do
- Drive the monolith-to-services decomposition using proven patterns like Strangler Fig to improve system modularity, reliability, and developer velocity across the engineering organization.
- Architect and scale event-driven systems and AI infrastructure, including embedding pipelines and real-time chat features using a modern stack of TypeScript, Node.js, Go, and AWS.
- Mentor engineering teams through code reviews and design sessions while establishing high standards for AI-assisted development tools to accelerate delivery and define team-wide engineering best practices.
The ideal candidate
- Possesses 10+ years of hands-on software engineering experience with a proven track record of shipping and scaling distributed systems for tens of millions of monthly active users.
- Deeply proficient in TypeScript, Node.js, Go, and AWS, with specific expertise in optimizing PostgreSQL for high-throughput production environments through query optimization, partitioning, and replication.
- Highly experienced in service-oriented architecture transitions and familiar with modern AI/ML infrastructure components, including vector databases, embedding pipelines, and LLM API orchestration.

We never post fake jobs
This isn't a trick. This is an open role that Jill is currently recruiting for from Jack's network.
Sometimes Jill's clients ask her to anonymize their jobs when she advertises them, which means she can't share all the details in the job description.
We appreciate this can make them look a bit suspect, but there isn't much we can do about it.
Give Jack a spin! You could land this role. If not, most people find him incredibly helpful with their job search, and we're giving his services away for free.
