    Collaborate closely with Data Scientists to provide optimized features and reliable datasets for real-time ML models.
  • Optimize for Scale:
    Tune our big data environment for maximum performance, ensuring our infrastructure (AWS/GCP, Spark, Airflow) grows as fast as ouruser base.
  • Bridge the Gap:
    Work with Product and Engineering teams to turn business requirements into robust data schemas and reliable analytical assets.

Who You Are ✨

    Data Governance,
    including data cataloging, lineage tracking, and implementing data quality frameworks (e.g., Great Expectations, dbt tests).
  • Cloud Native:
    Deeply comfortable managing data infrastructure on cloud platforms (AWS, GCP, or Azure).
  • Problem Solver:
    You thrive on optimizing slow queries and fixing bottlenecks in high-through put systems.

ROLE OVERVIEW:

We’re looking for a hands-on R&D Mechanical Engineer to design and build a variable-angle wind tunnel for testing our VTOL delivery drones.

The wind tunnel will generate controlled wind speeds and directions while the aircraft remains mounted on a force-measurement test stand. The complete system will include motors, propellers, structural frames, airflow components, force sensors, actuators, and a large pivoting mechanism that allows the wind angle to be adjusted automatically.

This is a highly practical role involving CAD design, prototyping, fabrication, assembly, instrumentation, testing, and continuous improvement.

Design the complete wind tunnel structure and airflow system

Select and integrate motors, propellers, bearings, actuators, belts, gears, and structural components

Develop a pivoting mechanism that can automatically change the wind tunnel angle

Design test stands and fixtures for mounting VTOL aircraft

Integrate force sensors and other measurement equipment into the test setup

Create parts and assemblies in SolidWorks

Produce components using 3D printing, CNC machining, sheet materials, and workshop fabrication

Assemble, modify, and troubleshoot the physical system

Conduct airflow, vibration, structural, and mechanical tests

Work closely with flight-control and embedded-software engineers to integrate the wind tunnel into our verification pipeline

Improve the system based on test results and experimental data

QUALIFICATIONS:

Degree in Mechanical Engineering, Aerospace Engineering, Mechatronics, or a related technical field

Strong SolidWorks or equivalent CAD skills

Experience designing and building mechanical systems or test equipment

Familiarity with motors, propellers, bearings, belts, gears, actuators, and structural assemblies

Experience with 3D printing, rapid prototyping, and workshop fabrication

Comfortable using workshop tools such as drills, Dremels, saws, adhesives, and hand tools

Good understanding of mechanical loads, vibration, tolerances, airflow, and structural design

Experience with wind tunnels, test rigs, drones, robotics, or aerospace systems is a plus

Strong problem-solving skills and a practical, hands-on approach

Why You’ll Love Working Here

Design and build a unique variable-angle wind tunnel from the ground up

Work with an exceptionally talented team

Work on cutting edge drone & AI technology

Build real hardware and see it used in aircraft testing

Good compensation

Equity participation (Stock options)
