• Develop and implement innovative security testing methodologies specific to blockchain and DeFi environments
• Analyze new and emerging dApp and wallet attack vectors (phishing, session hijacking, malicious npm packages, RPC manipulation) and assess their potential impact on the ZetaChain ecosystem
• Lead or coordinate security audits and penetration tests for ecosystem projects, and drive timely remediation of findings
• Contribute to and help manage the bug bounty programs by validating and triaging reported vulnerabilities
• Create and maintain security guidelines, best practices, and documentation tailored for ecosystem developers

Who We Are: SkyTrade is the planet's first air rights marketplace (n to 1), operating at the intersection of Real World Assets (RWA) and Decentralized Physical Infrastructure Networks (DePIN). We work with institutional real estate players, homeowners, government agencies, drone logistics firms, and crypto-native investors. Our users range from high-net-worth property owners in Manhattan to DeFi degens in Singapore. You need to think in both Excel and memes.

We're a pre-TGE startup with massive ambition and a bias toward execution. You’ll work directly with the founders and lead the charge in establishing revenue-generating partnerships. This isn’t a sandbox BD role. It’s a frontline position where your actions open markets and shape the company’s trajectory.

What You Will Do: As Business Developer, your job is to identify, close, and scale commercial opportunities across the SkyTrade ecosystem. You’ll drive adoption of our platform with real estate asset owners, drone fleet operators, and telecom partners. You will:

• Build, qualify, and convert pipelines of commercial leads (institutional and retail)
• Close deals across multiple verticals including real estate, DePIN, drone logistics, and tokenized finance
• Identify and secure partnerships with air rights brokers, real estate developers, logistics companies, telcos, and token infrastructure players
• Create winning pitch decks, proposals, and deal structures tailored to diverse stakeholders
• Represent SkyTrade in meetings, demos, events, and negotiations across markets (real world and Web3)
• Work closely with product, legal, and marketing to ensure our offers match real-world needs and close loops fast
• Help define and iterate GTM strategy across geographies (U.S., MENA, LatAm, APAC)
• Report directly to founders with clear metrics, deal updates, and lessons learned

Who You Are: You’re an execution machine who gets things done, fast and right. You're naturally persuasive, commercially-minded, and adaptive to complex markets. You have:

• 4+ years of experience in BD, sales, or strategic partnerships (Web3, PropTech, DePIN, or fintech preferred)
• Deep interest in emerging infrastructure, tokenized assets, and real-world dealmaking
• Prior experience closing high-value B2B or B2G deals
• Strong understanding of property markets, crypto economics, and DePIN incentives—or the hunger to master them fast
• No fear of cold outreach, long pitch cycles, or demanding partners
• Excellent communication skills—both for pitching and structuring deals
• A record of hitting targets and building durable business relationships

Bonus: Experience working in start-ups, real estate, drone logistics, or infrastructure tokenization.

Skills & Tools You’ll Likely Use: CRM tools, investor decks, tokenomics models, partnership structuring, LinkedIn/email prospecting, BD workflows, Notion, Telegram, DeFi dashboards, Web3 messaging platforms.

What’s On Offer: Highly competitive salary, token equity, remote-first setup, and a chance to be part of a once-in-a-generation marketplace at the frontier of real-world and digital infrastructure.

We are committed to diversity, inclusion, and ambition. If you are mission-driven and ready to build the rails for low-altitude commerce, we want to hear from you.

What We’re Building

Ares is the newest product under Fountain Platform, focused on building a high-performance social trading platform for decentralized markets.

We believe trading has evolved. It’s no longer solitary — it’s cultural, real-time, and driven by memes, narratives, and reflexive attention loops. Yet most platforms are stuck using static tools built for yesterday’s market structure.

Ares is built for what trading has become — and where it’s going. We fuse speed, signal, social mechanics, and cultural context into a unified trading experience designed for today’s markets and tomorrow’s meta. At the core is a real-time intelligence layer that aggregates onchain and offchain data, surfacing the pulse of the market as it emerges. But information alone isn’t power — influence is. Ares turns trading into a collaborative, reputation-driven game where every trade is a signal and every user is a node of intelligence.

We’re not building a better terminal — we’re building the next dominant trading platform. One where culture leads, conviction is rewarded, and traders move markets together.

We’re backed by top VCs and Alliance (tier 1 crypto incubator). This is your opportunity to help define what the future of trading looks like from the ground up. This isn’t a typical job — and we’re not looking for typical people. We want resourceful, hungry, top 1% builders who move fast and think like founders.

About the Role

We’re looking for a Senior+ Fullstack Engineer (Backend-Leaning) to join our team. Our engineers tackle complex challenges at the core of trading infrastructure and user experience. At Ares, engineering defines the culture, pace, and quality of everything we build — pushing the limits of what’s possible in crypto-native systems.

What You’ll Do

• Work directly with the CEO and have transparency into other aspects of the company
• Architect important systems and anticipate strategic and scaling-related challenges via thoughtful long-term planning
• Design and implement infrastructure across the full stack — from high-performance frontends (Next.js + Tailwind) to backend systems (NestJS, PostgreSQL, Redis, and Solana RPCs)
• Build transactional engines that optimize for execution speed, accuracy, and UX under volatile, memecoin-driven conditions
• Drive the architecture of our real-time trading intelligence layer, fusing onchain and offchain signals into actionable interfaces
• Build integrations with external services (Telegram, bots, alerting engines) to power novel product experiences
• Ship fast and often — we deploy product daily and treat working code as the ultimate source of truth
• Collaborate directly with founders and senior engineers in a high-bandwidth, fast feedback loop
• Engage with early users — from CT influencers to alpha groups — and shape features around real workflows
• Take ownership over what you build, with freedom to make autonomous decisions and move without bureaucracy

Our Tech Stack

Nest.js, Solana, Redis, PostgreSQL, Typescript, Node.js, Materialize, gRPC, Drizzle, WebSocket, Google Cloud Platform, Terraform

You Might Be a Fit If You

• Have Node.js backend experience, ideally in performance-sensitive environments (e.g., crypto, fintech, gaming, real-time apps)
• Thrive in fast-paced, product-centric orgs where speed, autonomy, and ownership are the norm
• Can move independently and communicate clearly in async workflows
• Care deeply about craft, clean abstractions, and performance
• Have strong user empathy and can translate real behavior into real product
• Understand crypto and trading — and care about how and why traders behave the way they do
• Want to work with A-players — people who think like founders and ship like it

Why Join Us

• Work with a passionate team obsessed with product, velocity, and craft
• Ship real infrastructure used by real traders and degens — the kind of users who demand speed and performance
• Leave your mark on a product that could reshape how trading is done in the social-first, memetic era of DeFi
• It’s all greenfield — no legacy baggage, no bureaucracy, just you, a fast team, and the freedom to build what should exist
• Backed by top investors and Alliance DAO, with deep ties across DeFi
• Total flexibility — async, remote, and built for true builders who want to own their time and output
• You won’t be another cog — you’ll be a core part of shaping the next dominant trading platform
