Your mission:
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
• Extensive experience building backend systems with Node.js / TypeScript
• Strong architectural skills in distributed systems, async workflows, and service boundaries
• Deep understanding of data modeling and relational databases (PostgreSQL)
• Experience with AWS, Terraform, CI/CD, and modern DevOps 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
