Backend Engineer at Knowtex

This role is ideal for a mid-level backend engineer (3–6+ years of experience) who excels in Python and AWS environments. It is a perfect fit for someone who enjoys building the "plumbing" for complex AI systems and wants to work on a product with tangible social impact—specifically, horizontal scaling of voice AI to reduce clinician burnout. Based in San Francisco (hybrid), this position offers the chance to join an early-stage team founded by Stanford AI scientists during a period of "explosive growth." While the base salary isn't listed, the package includes meaningful equity, unlimited PTO, and premium healthcare. You’ll be working on high-stakes infrastructure that manages sensitive healthcare data across both commercial and federal (GovCloud) sectors. **You might be a good fit if you...** * Are highly proficient in Python and have experience productionizing ML model inference. * Have a strong grasp of AWS services like Lambda, ECS, and RDS. * Prioritize security and reliability, ideally with experience in HIPAA-compliant or regulated environments. * Thrive in a fast-paced startup where you’ll collaborate across ML, Frontend, and Integrations teams.
