We’re looking for a Senior Growth Engineer to accelerate the product flywheel across activation, retention, collaboration, and monetization. You’ll own end‑to‑end experiments and features, instrument product analytics, and ship fast, measurable improvements to core funnels. Expect a tight build–measure–learn loop, deep ownership, and lots of time with real users.

• Move the metrics that matter: design and run A/B/n tests to improve sign‑up, activation, collaboration, and retention; validate with trustworthy instrumentation and guardrails.

• Ship full‑stack growth features: onboarding flows, in‑product education, checklists, templates, referrals, pricing/paywall UX, and lifecycle triggers (email/in‑product).

• Build growth infra: experiment frameworks, targeting/segmentation, holdouts, attribution, and feature flagging.

• Collaborate deeply: partner with Design, Data, Product, Marketing, and Sales to prioritize hypotheses and land launches that actually change behavior.

• Keep the funnel healthy: anti‑abuse, bot/low‑quality traffic detection, and experiment ethics.

• 5–8+ years building and shipping user‑facing products with measurable impact; you’ve meaningfully moved activation/retention or revenue metrics at scale.

• Full‑stack Type Script experience across React, APIs and backend.

• Strong product sense + analytical rigor: you write SQL, define success metrics, and know when to pivot or double‑down.

• Experience with experimentation platforms (homegrown or vendor), event schemas, and cohort/segmentation analysis.

• Bias to action: you prototype quickly, validate with users, and ship.

• PLG experience in devtools or AI products
• LLM/agents experience (prompting, evals).
• SEO/landing‑page systems, referral loops, or collaboration network effects.
• Prior work on enterprise trials, self‑serve to enterprise bridges, and sales‑assist workflows.

• Competitive Salary & Equity
• 401(k) Program
• Health, Dental, Vision and Life Insurance
• Short Term and Long Term Disability
• Paid Parental, Medical, Caregiver Leave
• Commuter Benefits
• Monthly Wellness Stipend
• Autonomous Work Environment
• In Office Set‑Up Reimbursement
• Flexible Time Off (FTO) + Holidays
• Quarterly Team Gatherings
• In Office Amenities
