What are the responsibilities and job description for the Staff Backend engineer position at Seer?

About The Role

We are seeking a Backend Engineer to take deep ownership of the core platform services that power all of our products. In this role, you will drive the evolution of our backend architecture by identifying opportunities to improve or rebuild foundational systems, scoping and delivering significant engineering initiatives, and shaping the technical direction of the platform.

This role is ideal for someone who enjoys working across multiple domains and is excited to learn new technologies and unfamiliar subject areas.

You will primarily work with Python, GraphQL, CI/CD systems, infrastructure-as-code (AWS with Terraform), and a variety of modern AI-powered development tools.

What You'll Do

  • Own and evolve the shared backend services that support all product teams
  • Identify platform gaps and opportunities, then drive independently scoped engineering projects from concept to completion
  • Make architectural and technology decisions to enable new services and capabilities
  • Collaborate closely with product engineers to build practical, effective solutions
  • Improve platform reliability, observability, testing, and developer experience
  • Leverage modern AI tools to accelerate development and enhance engineering workflows

What We’re Looking For:

  • Strong experience with backend development, ideally in Python
  • Experience designing and implementing APIs (GraphQL experience is a plus)
  • Familiarity with cloud infrastructure (AWS) and infrastructure-as-code (Terraform)
  • Comfort working across multiple technical domains and learning quickly
  • Strong communication skills and the ability to work effectively with cross-functional teams
  • A bias toward ownership, fast iteration, and hands-on prototyping
  • Intellectual honesty, curiosity, and a willingness to experiment and continuously improve

Who You Are:

  • You are excited by the idea of building systems from the ground up and solving problems that don’t have existing playbooks
  • You thrive in smaller, high-output engineering teams where individuals have outsized impact
  • You enjoy writing meaningful amounts of code, iterating quickly, and improving clarity through action
  • You are comfortable with ambiguity and can navigate complex business or technical contexts
  • You are energized by leveraging AI tools to dramatically expand engineering productivity
  • You believe in ownership, continuous learning, and transparent communication
  • You understand that sometimes the best path forward involves throwing away code and starting over
