This role is with one of Dex's trusted partner companies.
We work closely with their teams to truly understand their culture, goals, and what they're looking for, so we can match you with the right opportunity and give you context about the role before you commit to a process.
The role
This company is building an AI operating system for the parts and equipment industries.
Think automotive spare-parts distributors, construction, agriculture - businesses sitting on vast, fragmented, unstructured data across legacy systems.
They're bringing modern AI to a blue-collar world, backed by leading VCs and founded by AI researchers.
This isn't another consumer app; it's a deep technical challenge with real-world impact.
You'll be one of the first US tech hires, working directly with the founders to build this system end-to-end.
This is a foundational role: you'll own data ingestion, cleaning, transformation, and the backend services that serve insights.
It's not a narrow feature-team role; it's about shaping the architecture, setting standards, and defining the engineering culture from day one.
Expect intense work, but also the rare chance to build the core product of a fast-growing company.
- The work
- Design, build, and own end-to-end data pipelines, from raw ingestion through cleaning and transformation.
- Develop robust orchestration workflows (Airflow-style DAGs) to ensure reliable, observable data movement.
- Integrate deeply with messy, legacy customer systems - on-prem databases, SFTP, CSV dumps, ERPs - to structure fragmented data.
- Architect and develop the core APIs and backend services that power AI insights for non-technical users.
- Define the engineering standards for data quality, schema evolution, observability, CI/CD, and deployment automation.
What You Bring
- 5+ years shipping backend services, ideally in an early-stage or fast-paced environment. (Exceptional mid-level engineers with 2-3 years will be considered.)
- Deep expertise in Python for APIs, services, workflow design, job scheduling, and orchestration tools.
- Proven ownership of end-to-end data pipelines, ensuring reliable and observable data movement.
- A builder's mindset: you thrive on startup intensity, have a track record of shipping, and are not looking for a 9-to-5.
- Your primary strength is backend engineering; this is not a full-stack or frontend-focused role.
