Description

This is a full-time Head of Product position. You will own the product function end-to-end: deciding what we build, who we build it for, and how we know it is working. You will work closely with our scientists, engineers, and BD team to turn deep research into products people actually want to use.

Responsibilities

In this role, you will split your time between the following responsibilities as needed:

Own the product roadmap

Decide what we build next and why, in collaboration with the senior leadership

Write clear specs that capture the problem, the user, and the success criteria

Cut scope ruthlessly to ship faster and learn sooner

Design the user experience

Map out user flows for complex on-chain interactions and make them feel simple

Work with designers and engineers to turn flows into shipped product

Build opinionated taste into every screen, transaction, and error state

Run experiments and measure what matters

Define the metrics that tell us whether a product is working

Instrument products properly and set up dashboards the whole team can read

Design and run A/B tests where the traffic supports it, and qualitative experiments where it does not

Treat the roadmap as a series of hypotheses to validate or kill

Stay close to the market

Use the products our partners, competitors, and the rest of the ecosystem ship, every day

Know the major protocols, wallets, aggregators, and frontends, and the people building them

Track what users are actually doing on-chain and translate that into product opportunities

Talk to users constantly

Run user interviews with developers, integrators, and end users of our infrastructure

Sit in on partner calls with BD to hear pain points first-hand

Bring the user voice into every product decision

Requirements

The requirements for this position are:

Shipped products to real users in crypto, DeFi, or web3, with metrics you can point to

Deep, current knowledge of the blockchain ecosystem and the products people actually use

Strong UX sense, with examples of flows or products you designed (UI design skills welcome, not required)

Hands-on experience with product analytics, A/B testing, and lean startup style experimentation

Comfortable spending money to test a market, and equally comfortable killing a product when the data says so

Stellar written and oral communication, in English

High agency, low ego, biased toward shipping

What we offer

The opportunity to shape products used across the blockchain ecosystem, with the support of a strong and influential team in the space

A salary of $120k-$180k annually (depending on level), plus stock options

Unlimited PTO

A budget for the equipment and tools you need to do great work

Fully remote, or work from our Athens office if you prefer

Opportunities to travel with work throughout the year

The opportunity to work and learn from world-class scientists from major universities in the field of blockchains, cryptography, and consensus

The chance to work with diverse partners, with many innovative projects, to learn the ins-and-outs of the blockchain market as it develops, and to remain on the bleeding edge of the latest developments in our field
