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
The physical economy—from automotive spare-parts distributors to heavy equipment and salvage operators—runs on decades of fragmented legacy ERPs, on-prem databases, and unstructured file dumps. Fresh off a major round from top-tier VCs, this company was founded by AI researchers to build the unified AI operating system that turns this messy data into automated pricing, inventory, and distribution intelligence.
You will partner directly with the founders to build the platform from the ground up. This is not an operational maintenance role or a narrow feature ticket queue; you will own end-to-end data ingestion, workflow orchestration, and backend service architecture, while defining the company standards for data quality, schema evolution, and deployment 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.
The work
- Architect and operate resilient ingestion pipelines that ingest, clean, and transform messy customer data across legacy ERPs, on-prem databases, and flat files.
- Design and maintain observable workflow orchestration systems using DAGs to keep critical data pipelines running reliably.
- Build robust, scalable Python APIs and microservices that power AI-driven insights and customer-facing interfaces.
- Set engineering standards across the stack, including data quality gates, schema evolution strategies, CI/CD automation, and observability.
What You Bring
- Substantial production experience designing, building, and operating backend systems and APIs in Python, with a track record in early-stage or high-velocity engineering teams.
- Hands-on ownership of end-to-end data pipelines and workflow orchestration engines such as Airflow or custom DAG-based systems.
- Deep experience tackling messy integrations across legacy protocols, on-prem databases, SFTP feeds, and unstructured file dumps.
- High agency and comfort operating with early-stage startup intensity, shaping architectural foundations without relying on predefined playbooks.

Why apply through Dex

Applying through Dex puts your engineering track record directly in front of the decision-makers and gives you a deep, honest briefing on their stack, roadmap, and compensation before the first interview.
