Growth Engineer

Most people who want a coach never get one. They think about it, they poke at a website, and then life happens and they go back to making it up on their own. The distance between wanting help and actually having a coach is short, and almost nobody crosses it.

We're hiring a Growth Engineer to close that distance.

You'll own the systems that bring new athletes into Farren, connect them to the right coach, and give them a reason to stay. Onboarding. Merchandising. Profiles, feeds, and sharing. Referral. The pieces that decide whether someone becomes an athlete here or another abandoned signup. This role is a combo of technical and growth focused. If you’re an engineer who loves straddling the boundaries between the business, the customer, and the code, this job is for you.

The playbook for this work is being rewritten every six months. The tactics that worked two years ago are dead. So we're not looking for someone with a binder of growth tactics. We're looking for someone who can form a sharp hypothesis, build the thing, read the data honestly, and be willing to throw out what they just built when the numbers say so.

You'll work directly with the founding team, our iOS engineer, and our coaches. You'll be responsible for outcomes, not tickets.

Own the backend behind acquisition, onboarding, and activation, from signup through coach match. This is python services and threading together service APIS.

Build the backend for our community surfaces: profiles, feeds, sharing, and the loops that make athletes want to bring other athletes.

Ship and instrument referral and merchandising experiments, then own the readout and the call on what happens next

Support the systems behind our website and marketing surfaces while our iOS engineer owns the front end

Extend our experimentation stack in PostHog so the whole team can move faster on evidence
