About the Role

We are hiring a Blockchain / Tech Team Lead to own the technical direction and engineering execution of our core blockchain infrastructure. This is a player-coach role: you will write and review production code, design protocol architecture, and lead a distributed team of senior engineers building high-performance, secure, and scalable Web3 systems.

You will be the final technical authority on smart contract architecture, node infrastructure, consensus integration, and on-chain data pipelines. If you have shipped production blockchain systems and can lead engineers at the deepest technical level — this role is built for you.

What You Will Actually Do (Technical Scope)

Architecture & Protocol Design

Design and own the end-to-end architecture of blockchain-based systems: smart contracts, off-chain services, indexers, and RPC infrastructure.

Define upgradeability, proxy patterns, and storage layout for production smart contracts (UUPS, Transparent Proxy, Diamond Standard).

Architect cross-chain and multi-chain solutions: bridges, message passing, rollup integration (Optimism, Arbitrum, zkSync, Base).

Make consensus-level decisions: validator setup, staking mechanics, finality, and reorg handling.

Smart Contract Engineering

Write, review, and audit Solidity / Rust smart contracts deployed to EVM and non-EVM chains.

Enforce security standards: reentrancy protection, access control, oracle manipulation resistance, MEV mitigation.

Lead integration with audit firms and drive remediation of findings.

Own gas optimization and contract efficiency at the opcode level.

Backend & Infrastructure

Build and scale indexing and data layers: The Graph, Ponder, custom indexers, subgraphs, and on-chain analytics pipelines.

Design high-throughput backend services in Node.js, Go, or Rust that interact with nodes, mempools, and RPC providers.

Manage node infrastructure: full nodes, archive nodes, validators, RPC endpoints (self-hosted and managed).

Implement observability and monitoring: Tenderly, OpenZeppelin Defender, Grafana, Prometheus,



on-chain alerting.

Team Leadership (Player-Coach)

Lead, mentor, and grow a team of 5–15 senior blockchain and backend engineers.

Set technical direction, run architecture reviews, and make final calls on critical trade-offs.

Own sprint planning, code review culture, and engineering standards.

Hire top talent: define roles, run technical interviews, and build the team.

Collaborate with product, security, and compliance to align engineering with business goals.

Security & Reliability

Drive threat modeling for all on-chain and off-chain components.

Own incident response for smart contract and infrastructure failures.

Establish CI/CD pipelines with automated testing, fuzzing, and formal verification where applicable.

Ensure 99.99% uptime for critical on-chain services.

What We Expect From You

6–10+ years of software engineering experience, with 3+ years in blockchain/Web3.

Production experience deploying and maintaining smart contracts on mainnet (EVM required; Rust/Solana/Cosmos a strong plus).

Deep knowledge of: EVM internals, gas mechanics, mempool dynamics, consensus algorithms, and cryptographic primitives.

Strong backend skills in at least two of: Go, Rust, Node.js/TypeScript, Python.

Proven leadership: you have managed engineers, run code reviews, and owned technical roadmaps.

Security-first mindset: you think like an attacker and design like a defender.

Fluent English for async communication across time zones.

Nice to Have

Experience with zero-knowledge proofs (zk-SNARKs, zk-STARKs, Circom, Noir).

Contributions to open-source blockchain protocols.

Experience with MEV, liquid staking,



or restaking infrastructure.

Familiarity with formal verification tools (Certora, Halmos, K Framework).

Why This Role Pays $300k–$500k

This is a top-tier technical leadership position with direct ownership of systems that hold real user funds and process real value. The compensation reflects:

Extreme scarcity: Few engineers combine deep blockchain expertise with proven team leadership.

Direct financial exposure: Your architecture decisions protect millions in on-chain assets — a single bug can be catastrophic.

Full technical ownership: You are the final decision-maker on protocol design, security, and infrastructure.

Market competition: Top Web3 companies globally compete for this exact profile, driving compensation to the top of the market.

Revenue impact: Your systems directly enable trading volume, TVL growth, and product scalability.

What We Offer

$300,000 – $500,000 annual salary, based on depth of experience and proven track record.

Token / equity package with long-term vesting.

Remote-first with async culture and flexible hours.

Hardware and tooling budget: your ideal dev setup, paid.

Conference and certification budget (Devcon, ETHGlobal, security summits).

Direct line to CTO and founders — no layers, fast decisions.

Relocation support if you prefer hybrid in a tech hub.

How to Apply

Send your resume plus a short technical note covering:

One blockchain system you architected and shipped — stack, scale, and outcome.

A critical security or performance problem you solved — how you diagnosed and fixed it.

How you lead engineers — your philosophy on code review, ownership, and mentoring.

Links to GitHub, deployed contracts, or audit reports are strongly encouraged.

Pay: $320,000.00 – $500,000.00 per year
