About the role

- Build a true platform rather than a fixed product with abstractions for infinite customizability.
- Write the spec, make architectural decisions, and ship the code for each problem assigned in weekly cycles.
- Interface directly with customers, participate in on-call rotations, and travel onsite as needed.
Qualifications
