About Travala
Founded in 2017 and now backed by industry giant Binance, Travala is the leading crypto-native travel booking service, offering 2,200,000+ properties across 230 countries, 600+ airlines, 50,000+ car rental locations, and 400,000+ activities globally.
Travala is a champion of cryptocurrency adoption, accepting over 100 leading cryptocurrencies alongside traditional payment methods. In addition to unbeatable prices via its Best Price Guarantee, Smart members on Travala can also enjoy additional discounts and loyalty rewards for eligible bookings made on the platform.
By incorporating next-generation blockchain technology and tokenised loyalty rewards, Travala.com is creating a cutting-edge experience at the intersection of Web3 and travel.
About the Role
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.
Key Responsibilities
Own the full listing deal cycle: prospecting, outreach, pitching, negotiation, and closing - across paid listings and in-kind/token-based listing arrangements
Build and actively manage a prioritized pipeline of target projects, using our existing research as a starting point and expanding it over time
Represent Travala directly to token project founders, BD leads, and treasury teams to pitch new listings
Negotiate commercial terms within approved guardrails, and manage the process through to signature
Keep leadership updated on pipeline status, deal velocity, and market feedback on our listing offering
Build strategic token partner relationships to drive revenue, while identifying broader ecosystem or co-marketing leads for internal teams.
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.
What You'll Have From Day One
Sales collateral and initial market research to support outreach and pipeline-building
Direct access to leadership for deal support and approvals - no bureaucratic layers slowing down a close
Requirements
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.
Benefits
Compensation: Competitive Base Salary + Uncapped Commission, depending on experience. Candidates with direct exchange-side listings experience would sit at the top of this range.
Travel Perks: Access to Smart Platinum tier on Travala.com for exclusive discounts and rewards.
Work-Life Balance: Remote working mode within a dynamic, high-performing international team culture.
Flexible Engagement Models: We offer tailored contracting or employment structures depending on your jurisdiction and location (to be discussed during the interview process).
Growth: Dedicated annual budget for courses, certifications, and tech conferences.
Web3 & Tech Exposure: Direct exposure to cutting-edge and trending technologies across Blockchain, Web3, FinTech, and real-world crypto adoption.
Premium Work Tools: High-end MacBook and necessary peripherals.
