• Strong preference for backgrounds in smaller, high-ownership environments
• Experience wearing multiple hats (application + infrastructure + deployment)
Why Join

• Variety of industries and problems
• Small, elite engineering team
• Opportunity to shape a fast-scaling consultancy
Location: San Francisco (5 days a week on-site)
Salary: $190k-$250k + 10-20% bonus + equity + sign on bonus
