About the Job

About us and our mission

Helio is a web3 payments platform built from the ground up to transform the online payments market that is dominated by giants who charge creators & merchants astronomical fees, pay out slowly, and create friction by asking end-users for too much information including sign-ups and card entries

We want to fix these issues using modern blockchain technology, stablecoins and decentralised identity. Our mission is to accelerate the adoption of web3 payments in the world economy. We do this by enabling merchants & creators to accept direct payment from consumers at zero fees for 1-time payments, enable pay streams with live cancellation & instant merchant payout by the sec/min while providing consumers with a friction-fee checkout experience that doesn’t require log-in or card details.

We’re an experienced team who built, scaled, and exited SaaS companies. Our ambition is to build Helio into a significant, lasting company that can fulfil our mission and grow to 1000’s of employees and millions of customers over time. We have exciting opportunities for exceptional talent to join the project at this early stage. We look for deep technical knowledge and exceptional motivation to make an impact and pursue new responsibilities. We hire both remote and in our London HQ.

You will help build and architect the foundation of the Helio software platform which all other systems will flow from and interact with.

We want to build a platform that is led by engineering excellence paired with pragmatic approaches to solving problems and delivering financial grade quality throughout our products and services.

Technical knowledge is critical but we are a startup treading in uncharted territory so attitude is even more important.
