Job description

Harmony is an open blockchain with data sharding and fast finality. Social games and community AI can use our onchain tokens for micro-payments, smart contracts for market pricing, and zero-knowledge proofs for data privacy.

Harmony’s mission is to scale trust and create a radically fair economy. Our platform is decentralized, scalable and secure to settle any transactions without trusted parties.

\uD83D\uDE80 Building a (Rocket)Ship
We are a Day-1 startup. Blockchains are becoming the foundation of the global economy, yet their adoption is at only 1%. That means that you as a pioneer and developer are shaping the future with 10X impact. Harmony is a community-driven project, a network with hundreds of applications, and a team wearing crazy ambitions on their sleeves. Because the invincible summer awaits!

For engineers, we value your deep understanding of how bytes work. You are a tool maker, a system hacker, and a math nerd all in ONE. Your typical day involves prototyping a top-conference research paper, debugging and profiling in hexdecimal, or writing updates to coordinate asynchronously with tens of engineers in the open. Building a blockchain is like jumping off the cliff while assembling the plane engine on the fly – but, if you can thrive in chaos, why NOT?

For creatives, we approve your obsession with user experience. You are a product designer, a brand manager, and an industry analyst all in ONE. Your typical day involves studying what delights and what hurts through hard metrics, writing long-form narratives on the why's and the do's, or scrumming tasks for a product launch to iterate with millions of users. Building a community is like sharing your blue heart while keeping the culture alive for decades – but, if this is your dream of 50 years, start NOW?

\uD83D\uDC99 See our project vision on Social A(G)I and Shard 1.
Responsibilities
  • Develop a blockchain with high security, scalability and decentralization.
  • Operate a network of 1000 nodes and $500M assets in open development.
  • Optimize 100M requests per second at $250K monthly operational cost.
Requirements
  • Bachelor degree in computer science – specializing in kernel, data structures or compilers.
  • 5 to 10 years of working experience including 1 year of startup experience.
  • 60-hour work week, daily 4-hour overlap with Pacific Time.
  • Exceptional communication and people skills.

We may use artificial intelligence (AI) tools to support parts of the hiring process, such as reviewing applications, analyzing resumes, or assessing responses. These tools assist our recruitment team but do not replace human judgment. Final hiring decisions are ultimately made by humans.
