Principal Backend Engineer

We're hiring a Principal Backend Engineer to help scale our platform from handling hundreds of customers to thousands, and from millions of documents to tens of millions. The ideal candidate has 8+ years of experience building and scaling backend systems, a strong CS foundation, and recent production experience with Python and cloud infrastructure.

Requirements

• Assess our current backend architecture and identify the highest-leverage areas for improvement around reliability, scalability, and security.
• Partner with the platform and infrastructure team to design and implement the core abstractions (data model, data pipeline reliability, deployment patterns) that will support our next phase of growth.
• Set the technical direction for how we scale our infrastructure from handling hundreds of customers to thousands, and from millions of documents to tens of millions.
• Raise the bar on backend engineering practices across the team: not through process for process's sake, but by building systems that make the right thing the easy thing.
• Long-term, this role shapes how Heron's entire platform evolves. You'll be the person who ensures our backend can support whatever product throws at it.

• Occasional travel for retreats and to work with the team
• Competitive benefits: health insurance; pension/401k; uncapped annual leave; parental leave
