Energy Jobline ZR
Energy Jobline is the largest and fastest growing global Energy Job Board and Energy Hub. We have an audience reach of over 7 million energy professionals, 400,000+ monthly advertised global energy and engineering jobs, and work with the leading energy companies worldwide.
We focus on the Oil & Gas, Renewables, Engineering, Power, and Nuclear markets as well as emerging technologies in EV, Battery, and Fusion. We are committed to ensuring that we offer the most exciting career opportunities from around the world for our jobseekers.
Job Description Career Renew is recruiting for one of its clients a Senior/Lead Smart Contract Engineer - this is a fully remote role for candidates based in the US or Europe (if they can overlap at least 6 hours with EST timezone). Salary range: 250-500K USD yearly.
We are the largest decentralized perpetual exchange on Arbitrum, processing over
$20 billion in cumulative trading volume
since launching in October 2024. We enable leveraged trading of real-world assets—commodities, forex, indices, and stocks—alongside crypto, bringing global markets onchain with full self‑custody.
Our momentum:
$150M daily trading volume
$40M+ TVL with 10x growth in 2025
26% of Arbitrum's total DEX activity
Backed by General Catalyst, LocalGlobe, and Susquehanna International Group
We're a small team building critical infrastructure at the intersection of DeFi and traditional finance. Our backend systems process thousands of trades daily, integrate multiple oracle networks, and provide institutional‑grade reliability for a protocol handling billions in volume.
The Role We're looking for an exceptional Senior or Lead Smart Contract Engineer to help scale our protocol as we expand to hundreds of markets and billions in daily volume. You'll work directly with our founding team (Harvard/Bridgewater/BlackRock) to architect and implement critical protocol upgrades, new market mechanisms, and infrastructure that enables the next of onchain derivatives.
This is not a junior role. We need someone who has
built perpetual DEX smart contracts in production
and understands the nuances of funding rates, liquidations, margin management, oracle integration, and keeper systems at scale.
Required Skills & Experience Must‑Have Experience
3+ years building production smart contracts in Solidity
Direct experience building smart contracts for a perpetuals DEX
(this is non‑negotiable)
Deep understanding of perpetual futures mechanics: funding rates, margin systems, liquidation engines, and PnL calculations
Production experience with oracle integration (Chainlink, Pyth, or custom oracles)
Strong grasp of DeFi protocol design patterns and composability
Experience with Hardhat, Foundry, or similar development frameworks
Track record of contracts handling significant TVL ($10M+) in production
Technical Expertise
Advanced Solidity optimization techniques and gas efficiency patterns
Smart contract security best practices and common vulnerability patterns
Experience coordinating external security audits
Understanding of Layer 2 scaling solutions (Arbitrum, Optimism, etc.)
Proficiency with automated testing and continuous integration for smart contracts
Soft Skills
Ability to work independently with minimal oversight in a remote environment
Strong written communication for technical documentation and code reviews
Comfortable with fast‑paced startup environment and rapid iteration
Must be available for 4 hours daily overlap with Eastern Time (9 AM - 6 PM ET)
Why Join Us? Impact & Ownership
Be one of a small team building a protocol processing billions in monthly volume
Own critical components of the protocol from design to deployment
Ship code that directly impacts thousands of users and massive trading volume
Influence product direction and technical architecture decisions
Technical Challenge
Solve genuinely hard problems at the frontier of DeFi and TradFi convergence
Work with cutting‑edge oracle infrastructure and Layer 2 technology
Build systems requiring institutional‑grade reliability and security
Tackle novel problems around onchain RWAs that few others are solving
Growth Trajectory
Join during explosive growth phase (10x TVL increase in 2025)
Platform has demonstrated clear product‑market fit with sustained traction
Well‑funded with runway from top‑tier VCs (General Catalyst, LocalGlobe, SIG)
Positioned at the center of the expanding RWA narrative in crypto
Team & Culture
Work with founders from Harvard, Bridgewater, and BlackRock
Small team means high impact and visibility
Remote‑first with flexible working arrangements
Open‑source development practices and transparent collaboration
Competitive compensation including equity/tokens
Compensation & Package + tokens and equity
