About TestBox

TestBox was founded with a bold mission: to fundamentally transform how software is bought and sold. We’re building an innovative platform that empowers buyers with transparent, interactive software experiences, while equipping sellers with powerful tools to deliver exceptional buying and onboarding journeys. Our core technologies - synthetic data, intelligent orchestration, and our unique product graph - help teams achieve faster implementations, clearer insights, and increase trust with their customers.

At TestBox, we're not just improving demos; we're building the next generation infrastructure for software transactions, creating seamless experiences from initial interest to successful onboarding and beyond.

We're a fast-growing startup built by a team that values experimentation, velocity, and customer impact. We’re backed by world-class investors and are building a platform that’s disrupting the traditional B2B sales motion.

Role Overview

We’re hiring our first dedicated AI Data Engineer to partner with our growing Solutions Architecture team. You’ll be the go-to expert for crafting, transforming, and operationalizing demo-ready datasets that fuel our most complex customer environments.

You’ll work hand-in-hand with Technical SAs (based in Brazil) and Customer-facing SAs (based globally) to bring product stories to life through clean, smart data. You’ll unblock implementation roadblocks, speed up delivery, and enable better customer storytelling.

This is a builder role, not a maintenance role. You’ll help define what great looks like and establish the blueprint for future team growth.

What You’ll Do

Data Creation & Transformation

  • Design and build high-quality, fictional datasets across industries and personas
  • Transform structured inputs (e.g., CSVs, JSON, Postgres etc.,) into usable tables and mock user behavior
  • Translate technical specs into production-ready data for each customer implementation

Technical Delivery

  • Collaborate with Technical SAs to build and QA environments
  • Own the most complex and reusable data transformations across all implementations
  • Set up systems that scale data work across customers without duplicating effort

Workflow Optimization

  • Maintain and improve internal tools/scripts for dataset generation and transformation
  • Identify opportunities to templatize common needs and speed up implementation velocity
  • Partner with Engineering and Product teams as needed to expand automation capabilities

Team Collaboration

  • Join grooming, standups, or async updates with Technical SAs and CE leads
  • Provide guidance and unblock Technical SAs on advanced data modeling issues
  • Ensure each SA pod is shipping environments with best in class data stories

Who You Are

  • You’re resourceful, structured, and detail-obsessed
  • You love solving technical puzzles and designing clean, elegant data systems
  • You work well with ambiguity and are excited to shape a new role in a fast-moving startup
  • You communicate clearly across technical and non-technical teams

Preferred Experience

  • 3–6 years in Data Engineering, DataOps, Solutions Data, or equivalent roles
  • Strong skills in data transformation using Python, SQL, or scripting tools
  • Experience working with APIs, automation platforms, and data formats (CSV, JSON, etc.)
  • Familiarity with GTM tools (CRM, support, marketing platforms) or sandbox/test environments
  • Bonus: Experience using AI for synthetic data generation
  • Bonus: Experience in pre-sales or implementation engineering environments

Why Join TestBox

  • Shape a high-impact role from day one
    Accelerate how world-class GTM teams build and tell stories with data

  • Join a company obsessed with customer experience, speed, and scale
