The company’s platform sits at the intersection of traditional finance, Web3, and tokenized assets, powering blockchain-based financial workflows used by leading financial institutions, and shaping how digital assets, wallets, tokenized securities, and decentralized systems are experienced by end users.

Responsibilities

  • Own the roadmap and full product lifecycle for customer-facing Web3 applications across web and mobile.
  • Design and optimize user journeys across wallets, token flows, signing flows, transaction experiences, and on-chain interactions.
  • Translate complex blockchain concepts, including wallets, permissions, signing, and token interactions, into intuitive product experiences.
  • Work closely with engineering on APIs, distributed systems, implementation details, system behavior, and edge cases.
  • Build products supporting treasury management, collateral management, repo financing, trading workflows, and asset lifecycle management.
  • Leverage AI tools such as Claude, ChatGPT, and Copilot to rapidly prototype, create mocks, iterate, and improve product specifications.
  • Collaborate with product, engineering, business, compliance, and institutional stakeholders to deliver scalable and compliant solutions.

Qualifications

  • 3+ years of Product Management experience.
  • Hands-on experience in Web3, crypto, DeFi, digital assets, or blockchain-based products.
  • Strong understanding of blockchain transactions, wallet interactions, signing flows, permissions, token behavior, and on-chain systems.
  • Experience building Web3 applications, wallet experiences, tokenized products, blockchain-based user flows, or crypto platforms.
  • Understanding of financial systems and asset flows, including trading, treasury, collateral management, or tokenized assets.
  • Strong product ownership mindset with the ability to independently define, design, and iterate on product flows.
  • Experience working closely with engineering teams, APIs, distributed systems, and technical product environments.
  • Hands-on use of AI tools for product design, prototyping, iteration, and workflow acceleration.
  • Excellent communication skills in English and a proactive, execution-oriented mindset.

Application conditions

  • Full-time position.
  • The listing header gives the location as Remote (London, England, GB), while the description states ‘London / Hybrid’, indicating attendance that is hybrid in London; a remote posting does not by itself imply worldwide eligibility.
  • Residency, work authorization, time zone, and specific language requirements are not stated apart from English communication skills being required; confirm them on the original page.

Preferred qualifications

  • Experience with tokenized assets, digital securities, stablecoins, DeFi applications, trading systems, liquidity platforms, or settlement infrastructure.
  • Familiarity with account abstraction, smart contract wallets, session keys, or blockchain security considerations.
  • Experience working with institutional financial clients, regulated financial environments, KYC / AML workflows, or financial infrastructure platforms.
  • Experience building mobile-first or responsive Web3 applications.

Compensation and benefits

  • No pay range, currency, equity, insurance, leave, or allowances are specified in the source.
