- Stay at the forefront of emerging AI tooling and practices to improve engineering workflows
- Collaborate cross-functionally with product, data, and go-to-market teams in an async-first environment
- Identify and eliminate single points of failure to improve system resilience
What they're looking for
- 6+ years of experience building large-scale backend systems and APIs

- Proficiency in Python, Go, React, and TypeScript
- Experience with Kubernetes, AWS, Datadog, and relational/NoSQL databases
- Strong command of SQL and thoughtful database modeling

The hot takeJeff's read on Postscript
Likes: Their 4.2 Glassdoor score is relatively strong for companies with more than ten reviews. They have a clear perks & benefits section. They were shared on the Forbes Best Startup Employers List. They have solid testimonials.
Dislikes: The first few folds is about who THEY are and what they expect YOU to be. Companies really should start the same way you would by selling a prospect: target audience first, you second.
