About the role

Senior Software Engineer responsible for setting technical direction, designing scalable platform services, and embedding AI-native capabilities into production systems at interface.ai.

Responsibilities

  • Lead the design and implementation of platform services — scalable, observable, and maintainable systems that power our AI products
  • Own technical decisions end-to-end: architecture, APIs, data models, performance, and security
  • Build and extend backend systems in TypeScript and Python; shape frontend experiences in JavaScript
  • Drive the integration of LLM-based and agentic AI capabilities into production systems — this is applied AI engineering, not research
  • Define and enforce engineering standards: code review, testing strategies, deployment practices, and incident response
  • Embed AI-native tooling (Claude Code, Cursor) into your daily workflow and help the team get better at it
  • Work side-by-side with product, design, and data — in the office, in real time, every day

Qualifications

  • 3+ years of software engineering experience with a track record of shipping impactful, production-grade systems
  • A portfolio of work you led, not just contributed to — you can walk through design decisions, trade-offs, and outcomes
  • Deep proficiency in TypeScript and/or Python; solid JavaScript for frontend contributions
  • Strong platform engineering instincts: distributed systems, API design, cloud architecture (AWS/GCP), observability
  • Fluent in AI/ML engineering: you've built on top of LLMs, understand prompt engineering, and know where AI adds value — and where it doesn't
  • Experience designing systems under real constraints — latency, reliability, cost, and scale
  • BS/BA in Computer Science; graduate degree a plus
  • Self-directed and decisive: you identify problems before they're assigned, propose solutions before they're requested, and close loops without reminders
  • In SF, committed to 5 days/week — the collaboration is real and intentional
