About the role

What You’ll Do

  • Own products and systems end-to-end — from scoping what to build, to shipping, to monitoring and iterating post-launch
  • Build backend and full-stack systems that serve millions of users with high performance and reliability
  • Design clean, scalable APIs consumed by web, iOS, and Android clients
  • Collaborate closely with Product, Design, Data Science, and peer engineering teams
  • Run experiments, instrument metrics, and make data-informed decisions about what to build next
  • Communicate proactively and with high bandwidth — concise & information-dense async updates, stakeholder alignment, low entropy
  • Raise the technical bar through code quality, architectural thinking, crisp abstractions, and mentorship

What You’ll Need

Required

  • 5-7+ years of software engineering experience
  • Backend or full-stack experience building consumer products at scale
  • Strong API design skills — you’ve built APIs consumed by multiple client teams and have opinions about how they should work
  • A generalist, get-it-done attitude paired with genuine technical depth in at least one area
  • Comfort with high ambiguity — you can scope what matters, make tradeoffs, and drive forward without a fully defined spec
  • Excellent communication skills — your written updates are clear and dense, and you collaborate well across teams
  • Product intuition — you think about the end user in addition to the system

Strong Plusses

  • Experience with feed architecture, recommendation systems, content ranking, or search/retrieval at scale
  • Experience shipping social product features (follow graphs, notifications, engagement systems, publishing flows) at a consumer company
  • Power user of social media with genuine intuition for why engagement mechanics work (familiar with network effects, NFX literature, creator dynamics)
  • Hands-on experience with AI image and/or video model inference — diffusion models, token-based inputs, LoRA tuning, inference optimization
  • Full-stack capability including modern frontend (React, TypeScript, NextJS)
  • Mobile-first API design experience working directly with iOS/Android teams
  • Experience building 0→1 products and existing on existing products in a startup environment
  • Web experience with Python, Django, Kafka, Elasticsearch, Postgres, Redis
  • Technical leadership experience
  • A love of music, whether you’re an avid listener or musician yourself

  • Company Equity Package
  • 401(k) with 3% Employer Match & Roth 401(k)
