Blockchain Lead

Lead Blockchain Engineer / Head of Crypto Protocols

Location: Kirkland, WA (Hybrid or Remote options possible)

Reports To: Co-Founder & CTO of hushh @Justin Donaldson

Role Overview

In this role, you will be the primary owner of the hushhcoin protocol end-to-end—from ideation and architectural choices to mainnet launch and post-launch governance. You will ensure hushhcoin is robust, secure, and compliant, and you will integrate privacy-preserving features that allow hushhcoin to function not only as a stablecoin but also as a unique platform for “human brand value” (akin to a “Zestimate” for an individual).

This position requires mastery of smart contract development, stablecoin peg mechanisms, zero-knowledge proofs (or related privacy tech), and an ability to navigate both the technical and regulatory complexities of launching a 1:1 USD-pegged token.

Key Responsibilities

1. Token Architecture & Protocol Design

• Design the hushhcoin protocol for stability, security, and modularity, leveraging best practices from existing stablecoins (e.g., USDC, DAI, GHO).

• Determine the optimal collateralization model (fully fiat-backed, crypto-collateralized, or hybrid) to maintain a reliable USD peg.

• Integrate identity and privacy features (e.g., soulbound tokens, ZK proofs) to track and update each user’s public “brand value” in a privacy-preserving manner.

2. Smart Contract Development & Audit

• Implement core token smart contracts (ERC-20 for hushhcoin, additional contracts for collateral vaults, oracles, and governance).

• Write, review, and maintain secure Solidity or Rust code (depending on chain) and ensure thorough testing.

• Collaborate with third-party auditors to complete security reviews and compliance checks prior to mainnet launch.

3. Blockchain Infrastructure & Scalability

• Evaluate and select the optimal blockchain deployment strategy (Ethereum L1 vs. L2 solutions like Arbitrum/Optimism, or other chains like Solana or custom Cosmos-based).

• Develop strategies for bridging hushhcoin across multiple ecosystems, ensuring high throughput and low fees where appropriate.

4. Peg Stability & Liquidity Management

• Design and manage redemption/mint mechanisms, ensuring hushhcoin maintains a $1.00 peg under stress.

• Oversee the creation and seeding of liquidity pools on DEXes (Uniswap, Curve) and work with market makers to ensure hushhcoin is tradable with minimal slippage.

• Implement oracles and potential yield strategies (ERC-4626 vaults) to manage reserves in a transparent, fully-audited manner.

5. Privacy & Data Integration

• Integrate advanced cryptography (zero-knowledge proofs, secure multi-party computation) to protect user data in the hushh ecosystem.

• Collaborate with hushh’s data and AI teams to allow for privacy-preserving updates of each user’s brand-value token/score.

• Ensure user data vaults and on-chain/off-chain interfaces comply with relevant privacy laws (GDPR, CCPA).

6. Regulatory & Compliance Coordination

• Work closely with legal counsel to ensure hushhcoin issuance meets regulatory requirements (FinCEN, SEC, MiCA in EU, etc.).

• Help design and implement robust KYC/AML procedures for hushhcoin minting/redemption processes.

• Provide technical inputs for ongoing audits, compliance disclosures, and licensing efforts.

7. Team Leadership & Collaboration

• Recruit, mentor, and lead a small team of blockchain developers, DevOps engineers, and cryptography specialists.

• Collaborate cross-functionally with Product, AI, Legal, and Marketing teams to ensure hushhcoin integrates smoothly into hushh’s broader data/value ecosystem.

• Drive best practices in code quality, security, and project management.

8. Post-Launch Maintenance & Iteration

• Establish ongoing monitoring systems to track hushhcoin’s peg stability, liquidity, and security.

• Oversee protocol upgrades and governance proposals as hushh evolves from a centralized to a more decentralized structure (if applicable).

• Manage incident response plans for potential exploits, black swan events, or compliance shifts.

Required Qualifications & Experience

1. Blockchain & Smart Contracts

• 3+ years of hands-on experience in blockchain engineering, specifically with Solidity (Ethereum) or Rust (Solana/Cosmos).

• Demonstrable end-to-end experience taking a crypto project from prototype to mainnet launch (bonus if it was a stablecoin or DeFi protocol).

• Deep understanding of ERC-20, ERC-721/1155, ERC-4626 vault standards, or equivalent on non-EVM chains.

2. Stablecoin & Tokenomics

• Proven track record or strong academic/research background in tokenomics—designing peg mechanisms, collateral strategies, and liquidity incentives.

• Familiarity with leading stablecoins (USDC, DAI, GHO, FRAX) and their strengths/weaknesses.

• Knowledge of oracle design (Chainlink, Band, Pyth) and how to maintain trustless price feeds.

3. Security & Auditing

• Strong grasp of smart contract security—common vulnerabilities (reentrancy, flash loan attacks, oracle manipulation) and mitigations.

• Experience working with third-party auditors, plus a track record of shipping audited code in production.

• Ability to respond to security incidents with composure and leadership.

4. Privacy & Cryptography

• Experience or demonstrated interest in zero-knowledge proofs (ZK-SNARKs, zk-STARKs, Bulletproofs) or privacy-preserving protocols (e.g., Aztec, zkSync).

• Familiarity with on-chain/off-chain data encryption, secure enclaves, or multi-party computation is a big plus.

5. Regulatory Awareness

• Understanding of current crypto regulatory landscapes—particularly stablecoin regulation in the U.S. (FinCEN, SEC) and EU (MiCA).

• Comfortable implementing KYC/AML flows if necessary, and working with legal teams on compliance frameworks.

6. Collaboration & Communication

• Excellent communication skills to explain complex blockchain topics to non-technical stakeholders and potential investors.

• Track record of working on cross-functional teams—close collaboration with product managers, designers, AI/ML engineers, or compliance leads.

7. Education

• Bachelor’s or Master’s degree in Computer Science, Electrical Engineering, Mathematics, or a related technical field. Equivalent hands-on experience is also valued.

• Additional certifications (e.g., in cryptography, cybersecurity, or blockchain engineering) are a bonus but not mandatory.

Preferred / Nice-to-Have Qualifications

• DeFi Protocol Experience: Prior experience shipping or maintaining a DeFi protocol (e.g., liquidity pools, yield optimizers).

• AI Integration: Familiarity with building APIs or protocols that interface with AI/ML services, especially around data ownership and preference modeling.

• DAO Governance: Experience designing or implementing on-chain governance frameworks (Snapshot, Tally, Aragon, etc.).

• Product Mindset: Ability to think beyond code—envision how hushhcoin can integrate into consumer-facing apps, brand marketing portals, or data-sharing workflows.

• Start-up Experience: Comfort in a fast-moving, ambiguous environment with minimal bureaucracy and high autonomy.

What Success Looks Like

• Security & Trust: The hushhcoin protocol launches with robust audits, minimal vulnerabilities, and a track record that gains user and market trust.

• Stable Peg: Hushhcoin maintains a consistent $1.00 peg under both normal and stressed market conditions, with healthy on-chain liquidity.

• Seamless Identity Integration: A working soulbound token or privacy-preserving identity layer that updates each user’s “brand value” dynamically, without exposing personal data.

• Compliance & Credibility: Positive regulatory posture, with hushhcoin recognized as a legitimate, fully-backed stablecoin by major jurisdictions.

• Ecosystem Adoption: Hushhcoin is integrated into hushh’s broader product ecosystem (user data vaults, brand marketing tools, AI personalization) and fosters a growing user/brand community.

• Team Growth & Leadership: A strong, motivated engineering team delivering on-time milestones while upholding best practices in code quality and security.

Interested candidates should provide:

• Résumé highlighting relevant blockchain/stablecoin experience.

• GitHub/Portfolio links demonstrating past projects (especially any 0→1 token launches).

• Short Cover Letter explaining why hushhcoin’s vision resonates and a brief mention of relevant cryptographic/stablecoin projects you have contributed to.
