How You’ll Make An Impact
As a Machine Learning Engineer for Agentic AI & ML, you will work at the intersection of research and production. You will collaborate closely with internal stakeholders and customers to translate ambiguous challenges into effective, shipped features. You will work on features throughout the lifecycle - from discovery and model building to production deployment and maintenance. By designing and shipping ML and agentic systems, you will expand the platform's capabilities to fundamentally reshape how business owners run their operations and how workers manage transparency and work-life balance.
What You’ll Do
- Build and optimize ML models to enhance and extend Planday, framing problems from real metrics and engineering robust feature pipelines.
- Design and ship agentic systems involving tool use, function calling, and multi-agent orchestration for reliable planning workflows.
- Deploy and operate model services in production, ensuring performance for cost and latency through caching, batching, and quantization.
- Design and run rigorous evaluations, including LLM-as-judge and regression suites, so quality changes are always measured.
- Collaborate on turning research prototypes into reliable, observable production workflows and pipelines.
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.
Success looks like
- Stable and sustainable support for live ML services in production as our variety of deployments grows.
- Successful release of new features like auto-scheduler models and intelligent AI agent needs.
- Reduced ambiguity in model quality through the implementation of repeatable and high-fidelity evaluation sets.
- Proactive maintenance and debugging of production services, ensuring high reliability for end-users.
- Delivery of research-backed features that directly improve complex workflows like shift assignment.
What You’ll Bring With You
- 3–5 years of hands-on experience designing, building, and deploying machine learning or data systems in production environments.
- Strong collaborative skills - we are a small, high-impact team, and we view cross-functional partnership as a feature, not a bug.
- Solid grounding in ML fundamentals (metrics, validation, leakage) and a strong theoretical foundation in AI research.
- Practical experience shipping ML or data systems in production environments, beyond purely academic or notebook settings.
- Strong Python skills, including experience with numerical and dataframe libraries such as NumPy and pandas.
- Experience writing tested, maintainable, and observable code for services deployed to the cloud.
- Hands-on experience with LLM applications and agentic architectures, such as RAG, function calling, or planning workflows.
- Familiarity with data tooling (SQL, dbt, Snowflake/Databricks) and an end-to-end mindset for product building.
- MSc or relevant experience in a quantitative field, with a preference for researcher-oriented profiles with coding proficiency.
