Our story

With the adoption of blockchains and rise of decentralised wealth, merchants & creators will increasingly turn to onchain payments to tap into fast growing audience of crypto savvy users that love spending with their crypto wallets.

That’s where Helio comes in to play and we’ve made it easy for the first time for anyone to accept crypto payments. We power payments for +5,000 creators & merchants and 100s of thousands of unique active wallets. Set up in minutes & get paid instantly for E-commerce, NFT pre-sales, ticketing, subscriptions & digital products.

A few things merchants & creators can achieve with Helio

• Accept USDC, SOL, ETH, BTC & 100s of digital assets seamlessly as a method of payment and benefit from instant payouts & low fees

• Integrate the Helio Checkout Widget in your website with ease, or add our e-commerce plugin for WooCommerce or the Solana Pay plug-in for Shopify

• Launch a Pay Link in a few clicks for NFT pre-sales, gated payments, subscriptions, Discord memberships, video paywalling and more

• Use Helio Wallet to receive payments and offramp digital currencies to fiat / your bank account

• Integrate the Helio API for real-time USDC and other digital currency deposits in your app

• Enable traditional card payments for your customers, no wallet or crypto required, and always receive crypto

Who’s behind Helio?

We're an experienced team of builders backed by leading VCs, Lightspeed Faction & Peak Capital. The founding team previously built, scaled and exited two B2B SaaS companies for a total of $600m.

Make sure to connect your crypto wallet at https://hel.io/ to set up your first payment. We only interview people who have tried our product and have a strong desire to make it better!

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 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. 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.

You will have a passion for Web3 technologies including NFTs and all things blockchain.

• Fluency in Rust and Solidity or other similar smart contract languages

• 2+ years of experience in blockchain development.

• Practical experience deploying smart contracts on the mainnets of major blockchains

• Contribution to a crypto project with a substantial token market cap a plus

• Experience in containers, deployment pipelines, A/B testing, Blue/Green principles to prove what you’ve built

• A passion for automation and defining everything via CaC to drive platform consistency

• Ability to troubleshoot and investigate complex 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
