What are the responsibilities and job description for the Founding Engineer - TerraByte position at Pioneer Square Labs?
Founding Engineer
Terrabyte AI San Francisco, CA Full-Time
About Terrabyte
Terrabyte is building the intelligence layer for Earth - turning geospatial data into actionable insight at scale. We're an early-stage company moving fast, working directly with founders, and shipping products that matter. If you want to be part of building something from the ground up, this is the role.
The Role
We're looking for a Founding Engineer to help us scale our product and engineering foundation as we grow. You'll be one of the first engineers at Terrabyte, which means you'll have significant ownership over technical direction, architecture decisions, and the culture we build together. This isn't a role for someone who wants to execute a pre-written roadmap - it's for someone who wants to help write it.
You'll work directly with the founders, move fast, and care deeply about building systems that are both production-ready and built to last.
What You'll Do
Nice to have: Prior startup experience or time at a high-growth engineering org (hyperscaler, strong eng culture company)

- Leverage modern AI coding tools to move faster and build more
- 4-7 years of software engineering experience with strong fundamentals across backend and infrastructure
- Demonstrated track record building and scaling production systems
- Comfortable in early-stage ambiguity - you can define the problem, not just solve it
- Fluent with modern AI development tools (Claude, Cursor, Codex, etc.) alongside traditional engineering practices
- High ownership mindset and a bias toward shipping
