Travala.com is the world's leading Web3 travel booking platform, with AVA as its native utility token. We're hiring a Senior BD Manager to own new coin listings on Travala end-to-end — sourcing targets, pitching, negotiating, and closing deals. Listings may be structured as a traditional paid fee or as an in-kind token arrangement, decided deal by deal — the specific structure isn't the focus of this role, closing quality listings is. This is a hunter role, not a strategist or management role. You'll have sales collateral and initial market research to build from - you're not starting from a completely blank page. While this is a fully remote position, candidates based in the Asia-Pacific (APAC) region are preferred to align with working hours across our wider growth team and key internal departments, with flexibility for exceptional candidates in other locations. We’re looking for a Blockchain Engineer to explore and build new possibilities around RGB++, CKB, and Bitcoin. RGB++ is built around the UTXO model, so this role is particularly suited to engineers who understand Bitcoin, UTXO-based systems, or similar protocol-level architectures and are interested in exploring what new ideas can be built from that foundation. You’ll start with RGB++ — understanding what exists today, exploring what could come next, and turning promising ideas into tools, prototypes, or infrastructure that other developers can build on.

Act as primary BD liaison for internal teams (product, legal, marketing, finance) to coordinate workflows, documentation, and compliant token integration. Research and stay up to date with cryptocurrency market trends, emerging tokens, and innovative blockchain projects to identify potential listing opportunities. What's Not in Scope To keep this role focused and avoid overlap with our marketing team, the following sit outside this role: Post-signature announcements, co-marketing, and campaign work - owned by our CMO's team once a deal is signed. Broader strategic partnerships beyond listings (e.g. major platform integrations) - owned separately. Managing other BD staff -this is an individual contributor role, not a management position.

More skills

5+ years of professional experience in business development or sales within the blockchain or cryptocurrency industry. Deep understanding of Web3, including tokenomics, crypto payments, wallets, and market trends. Genuine Web3/crypto BD experience - you already understand how token teams evaluate exchange listings and partnership offers. Existing relationships in the space are a critical component - warm pipeline beats cold outreach. Senior enough to run a full deal cycle independently, without needing management oversight at each step. Genuinely commission-motivated. This role is structured for someone who wants their effort and results to show up directly in their paycheck - not someone seeking a flat, low-variability package. Strong sales instincts and comfort with rejection - this is a quota-driven, outbound-heavy role. Not looking for a “Head of BD” or management title - this is a hands-on, deal-closing role by design. Exchange-side experience (Preferred): Prior experience on a listings/BD team at a crypto exchange is a strong plus - you understand how listing conversations and decisions actually get made from the other side of the table. Experience managing social media, online communities, gaming communities, crypto communities, or digital brands. Strong understanding of Web3, cryptocurrency, blockchain, GameFi, or online gaming. Good knowledge of X/Twitter, Telegram and Discord and how content performs differently across each platform. Ability to communicate naturally in English with an international audience. Strong writing skills and the ability to turn an idea or update into engaging social content. Understanding of crypto culture, memes, trends, and community behavior. Ability to work independently without needing detailed instructions for every task. Comfortable communicating directly with users and handling both positive and negative feedback. Creative mindset and willingness to test unconventional ideas. Reliable, organized, and able to work remotely. Experience with any of the following is a strong advantage: Web3 gaming, GameFi, NFT communities, gaming projects, influencer outreach, partnerships, community launches, viral content, Reddit, TikTok, YouTube, or short-form video. Previous experience at a crypto exchange, blockchain company, Web3 startup, gaming studio, or crypto media project is welcome but not mandatory. Why join Portal Sever? You'll join a growing project at a stage where your ideas can have a visible impact. Solid blockchain fundamentals and experience working beyond application-level development. Strong hands-on engineering ability with Rust and/or JavaScript/TypeScript. Ability to take an idea from exploration to something tangible without needing a detailed specification. Enjoy figuring out what should be built, not only how to build it. Strong interest in Bitcoin, blockchain infrastructure, and protocol-level innovation. An open-source mindset and comfort building things that other developers can use and extend. Self-driven and comfortable working independently in a remote environment. Comfortable communicating in Chinese, with sufficient written English to read technical documentation and communicate asynchronously Hands-on experience with Bitcoin, UTXO-based systems, or other UTXO-based protocols CKB / RGB++ experience L1/L2 or blockchain infrastructure development experience Systems or embedded engineering background Meaningful open-source contributions or strong public technical projects Why This Role This isn't a role where you'll spend your time working through a predefined backlog. You'll start with RGB++, but you'll have room to explore broader possibilities around CKB and Bitcoin, develop your own ideas, and turn the most interesting ones into something real. You'll be building in the open, with the opportunity to create tools and infrastructure that other developers can use and extend. We care less about titles or years of experience than whether you're curious, self-driven, technically capable, and excited to figure out what should be built next. Experience as a market maker, liquidity manager, or professional crypto trader. Strong understanding of decentralized exchanges and automated market makers. Experience with Uniswap, Polygon, and EVM-compatible ecosystems. Knowledge of liquidity pool management and tokenomics. Familiarity with on-chain analytics tools. Strong analytical and quantitative skills. Ability to work independently in a remote environment. Experience supporting emerging blockchain projects. Understanding of treasury management. Experience with algorithmic trading or market-making tools. Knowledge of cross-chain liquidity strategies. Familiarity with Web3 analytics platforms. Experience in marketing, sales, or business development. Interest in blockchain, cryptocurrency, or Web3. Strong communication skills. Self-motivated and results-oriented.

This is an opportunity to participate in the growth of a long-term project while earning performance-based rewards. Important Representatives are expected to communicate accurately about UTOPOS and UTOP. Misleading statements, guarantees of profits, or investment promises are strictly prohibited. All marketing must be factual and professional. If you're passionate about Web3 and business development and want to help build the future of decentralized commerce, we'd love to hear from you.
