Single Grain | Start Growing · Los Angeles, CA · 2 mo ago
RemoteRemoteEngineering$50k/yrFull-time

Responsibilities

  • Own the conversion funnel. Audit the full free trial → paid activation flow, map drop-off points with data, and ship improvements that move conversion rates.
  • Ship production code independently. Build and deploy backend, frontend, and infrastructure changes without waiting for a dedicated DevOps team.
  • Run structured growth experiments. Launch a minimum of two activation experiments per month by Month 6; instrument event analytics to measure impact.
  • Build in-product expansion triggers. Design and ship a system that identifies expansion opportunities within the product and surfaces them to users.
  • Operate AI-native workflows. Use AI (Claude, Cursor, and similar) for scaffolding, refactoring, and test creation. Document repeatable prompt workflows. Contribute to internal AI SOPs.

Requirements

  • 3+ years of full stack engineering experience at an early-stage startup, with clear evidence of growth — promotions, expanded scope, or increased ownership over that time.
  • You've built and shipped a product end-to-end that real users paid for or actively used. You can speak to what you personally built, the problems you hit, and how you iterated.
  • You think in funnels, not features. You frame engineering decisions in terms of conversion, retention, and expansion — not just technical correctness.
  • You're an AI Power User. You don't just use AI occasionally — you've built repeatable workflows with it, quantified the time it saves you, and actively look for more ways to apply it.
  • You're comfortable with ambiguity and full ownership. You don't need a PM to scope your work. You can look at data, form a hypothesis, build a test, ship it, and measure the result.

Qualifications

  • Bachelor's degree in Computer Science, Engineering, or related field.
  • Experience with Agile methodologies and continuous integration/continuous deployment (CI/CD).
  • Strong understanding of web technologies including HTML, CSS, JavaScript, and frameworks/libraries such as React or Angular.
  • Experience with databases and SQL.
  • Knowledge of API design and RESTful services.
  • Experience with version control systems such as Git.
  • Experience with cloud platforms such as AWS, Google Cloud, or Azure.

  • $50K life insurance policy, paid 100% by the company.
  • 12 weeks of paid family leave, effective after the first year of employment.
  • Flexible Unlimited Paid Time Off.
  • $100 utilities stipend, paid out as an extra $50 per paycheck.
  • $60 UberEats credit each month.
  • A MacBook.
  • $500 WFH office reimbursement.
  • Fully remote — work from anywhere.
