Job Description

Career Renew is recruiting for one of its clients a Core Dev - Crypto - this is a fully remote role for candidates based in N / S America. Salary range : 120-200K USD yearly plus benefits.

We are on a mission to simplify DeFi and make sophisticated yield opportunities available to anyone, anywhere. Guided by our vision “to create transparent and reliable DeFi experiences that drive financial value and opportunity,” we translate complex strategies into intuitive, one-click products that empower users and institutions alike.

What We Build

Leverage Tokens – ERC-20 assets that bundle borrowing, swapping, and automated rebalancing into a single token, giving users amplified exposure without the headache of active position management.

Vaults – curated strategy vaults that automate liquidity deployment and risk management so capital never sits idle.

Staking – a straightforward way to lock SEAM and earn protocol fees.

Governance – SEAM holder community-led decision-making that steers new product launches, risk parameters, and treasury growth.

Why Work With Us

Category Ownership – We’re defining the next generation of DeFi primitives—packaged leverage—on Base and beyond. Your code will ship to hundreds of thousands of wallets and manage nine-figure TVL from day one.

Real Impact, Real Autonomy – Small, senior-heavy squads own problems end-to-end. From ideation through governance proposal to mainnet deploy, you’ll see your ideas come alive fast.

Open-Source & Community First – All core smart contracts are public, auditable, and designed for composability. We believe transparent code and open governance create trust and accelerate innovation.

Sustainable Incentives – Revenue flows back to stakeholders via Staking, aligning long-term protocol health with SEAM token holders.

Our Culture

Clarity Over Complexity – whether it’s UI copy or Solidity, we strip out jargon and surface only what users truly need.

Bias for Shipping – perfect is the enemy of good; iterative delivery wins.

Ownership at Every Level – if you spot a gap, you fill it.
