About us and our mission

Blockchain and Web3 technology has the potential to dramatically improve the way payments work on the internet simply because it’s cheaper and faster to send money directly to anyone, anywhere without the need for intermediaries such as banks. We believe in a world where Web3 becomes mainstream with 100s of millions, and ultimately billions, of users with many new projects flooding in, all in need of great payment tools.

Our mission at Helio is to accelerate the adoption of Web3 payments and we’re building a complete Web3 native-payments stack starting with Solana. We make it easy for anyone to get paid in crypto instantly using our pre-built checkouts or integrate payments directly into their store, app, content, game or platform.

Helio delivers a solution that’s cheaper, faster and offers a better UX than any other payments platform. Solutions include:

  • Pay Streams: on-chain, time-metered billing to dramatically lower the cost and flexibility of subscriptions, SaaS payments and memberships

  • E-commerce: spin up an e-commerce page in seconds to accept crypto payments instantly

  • Web3 paywalls: monetise gated/metered access to anything ⇒ events, games, data, video and more

  • Pay Links: lower the cost and increase the speed of day-to-day payments such as invoicing, freelancing, services, tipping, split-payments, salaries and more

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 serve 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 skills and singular motivation to make an impact and pursue new responsibilities. We hire both remote and in our London HQ.

You will:

You will help build and architect the foundation of the Helio software platform which all other systems will flow from and interact with. You will use all your previous experiences, skills and initiative to get things right from inception - which is to a naturally high standard of code, logic and engineering prowess in general. We want to build a platform that is led by engineering excellence paired with pragmatic approaches to solving problems and delivering Fintech 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. We’re looking for people that like uncertainty and want to figure out how to do things that haven’t been done before. You’re a true team player and inherently positive. Where others see problems, you see solutions.

  • +3 years of experience in frontend teams ideally using ReactJS, JavaScript/Typescript and NextJS

  • Experience of other mobile frameworks like Flutter, React Native or Kotlin is a plus

  • Natural ability to write clean and elegant code, whilst being diligent and pragmatic in equal measure

  • Data interoperation and UX skills. SQL first and foremost.

  • Ability to troubleshoot and investigate issues across systems

  • Desire to build, maintain and improve anything you work on with a high level of ownership

  • Above all this, we are looking for engineers that want to do the best they can, learn, improve, grow, lead, help others and add value every single day for yourself, your teammates and for Helio
