Job Description

Full Stack Software Engineer 

We’re looking for a full-stack software engineer to join a rapidly growing startup poised for nationwide expansion. This is a 100% on-site role located in Austin, TX. 

You’ll work closely with product and engineering teams to build, test, and maintain features as well as contribute to technical design and prioritize a product roadmap in a fast-paced, collaborative environment.

The ideal candidate will bring a product-driven mindset and lead initiatives focused on high-volume data scalability, applied AI integrations, and robust observability in production environments.

They’re a close-knit team that’s smart, humble, hungry to learn, endlessly curious, and takes full ownership of what they do

If you’re a curious, driven, resourceful engineer ready to build impactful solutions, we want to hear from you!

Responsibilities

  • Build meaningful features end-to-end from concept to design, code, test, and deployment.
  • Own complex, backend-heavy systems that handle large datasets and drive product intelligence.
  • Design clean, scalable Postgres schemas and write efficient queries to keep performance predictable.
  • Shape technical architecture, contribute to microservice design, API interfaces, and operational runbooks.
  • Write clean, maintainable, and well-tested code across frontend, backend, and data layers.
  • Collaborate with engineers, product, and design on priorities, trade-offs, and technical direction.
  • Raise visibility, strengthen observability through better logging, metrics, and tracing, so issues are obvious and fixes are fast.
  • Embrace ambiguity, propose solutions, challenge assumptions, and turn ideas into real, high-impact features.

Requirements

  • 5+ years building and delivering robust software solutions
  • Strong skills in Typescript and modern JavaScript frameworks (e.g., React/Next.js)
  • Proficiency in Python and API frameworks (Ruby on Rails knowledge a plus)
  • Experience with relational database schema design (e.g., Postgres)
  • Familiarity with large language models and text-processing tools
  • Knowledge of cloud platforms (e.g., AWS, GCP, Azure) and CICD pipelines
