Backend Engineer (Senior, Staff)

$160k - $220k

PRIMIS , Inc. Defunct

Location: Hybrid SF Bay Area
Compensation: $160,000-$220,000 base + equity

About the Opportunity

Our client is seeking a highly skilled Backend Engineer to help design and build robust, secure backend systems powering modern web applications and data platforms. This team intentionally prioritizes simplicity and reliability, maintaining a monolithic architecture until scale truly demands otherwise. Their philosophy is to focus engineering effort on customer value and product discovery while ensuring systems remain secure, stable, and maintainable.

What You'll Do

  • Design, build, and maintain clean, reliable backend services
  • Partner cross-functionally to define domain models and system architecture
  • Optimize performance, scalability, and system stability
  • Ensure strong security practices and data protection standards
  • Continuously improve code quality, infrastructure, and engineering processes
  • Stay current on backend engineering best practices and emerging technologies
What They're Looking For
  • Strong experience building and operating production web services and data systems
  • Deep proficiency in Python and at least one modern Python web framework (e.g., Django, FastAPI)
  • Solid understanding of databases, data modeling, and data pipelines
  • Familiarity with modern backend frameworks, tooling, and libraries
  • Experience with CI/CD workflows and automated deployment systems
  • Demonstrated commitment to writing high-quality, maintainable code
  • Strong problem-solving, communication, and collaboration skills

Research indicates that men will apply to a role when they only meet 50-60% of the descriptions, however, when looking at women and other minority groups, they can look for up to a 99% match in order to apply to a role. If you feel you are a fit for our role, please still apply, don't worry if you don't tick every single box. We'd still love to hear from you. We encourage underrepresented talent to apply to all our roles & support accessibility needs
