About the role

Role Summary

We are looking for a Senior Backend Engineer /Tech Lead who can operate as a senior individual contributor while also setting technical direction, establishing engineering standards, and mentoring the team as we grow.

This role is ideal for someone who has already worked as a senior/staff-level engineer or informal tech lead, and wants to take on more architectural ownership and long-term influence in a fast-moving AI-centric environment.

You will partner closely with the CPTO and collaborate with backend, AI, and product teams to deliver high-impact systems.

Architecture & System Ownership

  • Design and own core backend architecture across multiple services
  • Build and scale distributed, event-driven systems
  • Establish patterns for reliability, performance, and observability
  • Own major technical decisions and ensure long-term maintainability

AI-Enabled Systems

  • Architect integrations with LLM-driven components
  • Work on retrieval layers, inference pipelines, and structured output flows
  • Collaborate with AI engineers on evaluation, monitoring, and model integration

Infrastructure & Reliability

  • Oversee backend infrastructure using AWS, Terraform, CI/CD
  • Improve resilience, security, and operational excellence
  • Drive observability, monitoring, and instrumentation practices

Engineering Leadership (non-manager IC)

  • Define and enforce code quality, architecture standards, and review practices
  • Guide backend engineers through complex problem-solving and design
  • Contribute to hiring, interviewing, and onboarding future team members
  • Work closely with product to drive technical planning and roadmap execution

Your profile

Technical Expertise

  • Deep understanding of data modeling and relational databases (Postgre SQL)
  • Experience with AWS, Terraform, CI/CD, and modern Dev Ops tooling
  • Familiarity with AI/LLM system integration or strong motivation to learn quickly

Leadership Qualities

  • Strong communicator who can articulate trade-offs and technical reasoning
  • Collaborative, low-ego and pragmatic - prioritizes outcomes over ego
  • Bias for action - comfortable shipping fast in ambiguous 0→1 environments
  • System thinker - sees the big picture while delivering incrementally
  • Natural mentor to other engineers, even without formal people management
